2019 BMW 4 Series Convertible

The volume 2019 430i Convertible carries over the 2.0-liter TwinPower turbo four at 248 hp, unchanged from 2018; the 440i's inline-six lifts the model range to 320 hp (the separate M4 Convertible is not part of this entry).

258 lb-ft (350 Nm) arrives from roughly 1,450 rpm and holds on a broad plateau, which is why the 430i feels stronger in traffic than its horsepower figure implies.

BMW's own figure for the rear-drive 2019 430i Convertible is 6.0 seconds; the folding hardtop's roughly 4,040 lb curb weight costs a couple of tenths against the coupe, and independent tests of the same drivetrain have run a few tenths quicker.

The turbo four is smooth and effectively lag-free with peak torque by 1,450 rpm, and quiet enough with the roof down; what holds it out of the top band is character rather than manners — reviewers consistently note it sounds ordinary next to the 440i's inline-six and leans on augmented cabin sound.

The standard ZF 8HP eight-speed Steptronic is the benchmark torque-converter automatic of this era — quick, smooth, decisive gear selection and a well-judged manual mode, with no hunting despite eight ratios.

xDrive all-wheel drive was optional on both the 430i and 440i Convertible, so AWD is available across the range rather than locked to a top trim — but it is a paid option over a rear-drive default, and it is a road-biased on-demand system with no low range or terrain modes.

US convertible buyers got two gas turbo engines — the 2.0L four (430i) and the 3.0L inline-six (440i) — each with rear- or all-wheel drive, which covers mainstream needs; there was no hybrid, PHEV, EV or US diesel option in this body style.

EPA rates the volume 2019 430i Convertible at 27 MPG combined on premium gasoline — respectable for a roughly 4,040 lb retractable-hardtop luxury convertible, but unremarkable against the wider gas fleet the band covers.

24 MPG city from the turbo four with auto stop-start and the eight-speed automatic; the folding hardtop's weight keeps it from doing better in stop-and-go use.

Highway is this car's strongest efficiency showing — a tall eighth gear and small-displacement turbo return 34 MPG, genuinely good for a luxury convertible.

The 15.8-gallon tank paired with the 27 MPG combined rating gives about 427 miles of total range — enough for a comfortable day's touring, but mid-pack because the modest tank offsets the decent economy.

EPA's annual estimate is $2,800 at current premium prices — the 91-octane requirement, more than the consumption itself, is what makes this expensive to feed relative to its 27 MPG rating.

Premium unleaded is the specified fuel for the 2.0L TwinPower turbo — both the EPA ratings and BMW's quoted output assume 91 octane, so there is no cheaper way to run it and no flex-fuel or electrified alternative anywhere in the convertible lineup.

NHTSA carries the 2019 4 Series Convertible in both drivetrains (C RWD and C AWD) but every rating line returns "Not Rated" — no frontal, side or rollover test was run on this low-volume two-door. Held mid-band: the F33 shares its structure with the F30 3 Series, which did earn 5 stars as a sedan, but a retractable-hardtop body is not covered by that result.

IIHS never crash-tested the F32/F33 4 Series in any body style, so there is no Top Safety Pick award and no individual Good ratings to point to — 2019 is a late year of a structure introduced for 2014. No known crashworthiness concerns and a well-regarded related platform (the 2019 3 Series sedan earned TSP+) keep it off the floor, but an untested convertible cannot claim the mostly-Good band on inference alone.

For 2019 the 430i Convertible ships with no active-safety content at all: standard equipment is a rearview camera, front/rear Park Distance Control, rain sensor with auto headlights and non-adaptive Dynamic Cruise Control. Active Driving Assistant (5AS — forward collision warning, city collision mitigation, pedestrian warning, lane departure warning) is the $500 ZDA option, blind-spot detection another $500, and active cruise $1,200. Every feature this item measures is extra-cost, which is the bottom band — and it is the year's key separation from 2020, when BMW made 5AS standard.

The 4 Series has no IIHS front crash prevention rating in this generation, so nothing confirms real-world performance. When the $500 ZDA box is ticked the car gets city-speed collision mitigation with partial braking and daytime pedestrian warning — a competent pre-2020-architecture system with no nighttime pedestrian capability — but the volume car leaves the lot without it, so an as-delivered 430i Convertible has no automatic braking at all.

Active Blind Spot Detection is a $500 standalone option, or bundled into the new-for-2019 ZCV Convenience Package or the ZMP M Sport Package, and it is alert-only. The F33 offers no rear cross-traffic alert in any configuration and no safe-exit function. Optional-only alert coverage with a missing cross-traffic system sits in the bottom band.

The only lane function offered is lane departure warning — a steering-wheel vibration alert with no corrective steering — and for 2019 even that is optional inside the ZDA package rather than standard. There is no lane keep assist or lane centering on the F33 at any price, so nothing here approaches the centering quality reviewers judge by.

The 430i Convertible ships with 544 Dynamic (non-adaptive) Cruise Control; 5DF Active Cruise Control is a $1,200 standalone option that replaces it. When fitted, BMW's radar ACC is smooth and handles full-speed-range stop-and-go well, but there is no integrated highway assist mode on this generation and 5DF cannot even be combined with the M Sport package.

No hands-free highway system is offered in any 2019 4 Series configuration. BMW's Highway Assistant arrived years later and only on newer platforms with the required camera and mapping hardware; the F33's most capable option, Active Cruise Control, requires hands on the wheel at all times.

Full-LED headlights and LED fog lights are standard across the 2019 range following the 2018 LCI, with rain sensor and automatic headlights also standard. Adaptive Full LED Lights with cornering function and automatic high beams require the Executive Package, which itself requires ordering the Convenience or M Sport package. IIHS never rated 4 Series headlights, so nothing confirms Good performance and the standard non-adaptive units are competent rather than class-leading.

Roof down, sightlines are excellent in every direction — the convertible's structural advantage. With the three-piece retractable hardtop raised, thick rear quarters and a shallow backlight create real over-the-shoulder blind zones, and the compensating hardware is all optional: only the rearview camera and front/rear parking sensors are standard, while blind-spot detection, side/top-view cameras and Parking Assistant cost extra.

The F33 is a strict 2+2 with LATCH anchors in its two rear buckets and no rear doors — every installation means tilting and sliding a front seat and reaching over a high sill, and the low roofline makes leaning in awkward with the top up. Two seats is the hard ceiling, the standard wind deflector cannot be used with rear passengers, and rear legroom behind a tall driver is tight for a rear-facing seat.

The F33 Convertible is a strict four-seater with two rear buckets, unchanged for 2019 (a carry-over year within the 2014–2020 first generation). Four is the floor of the convertible normalization band, though it is two more seats than the roadsters this car is cross-shopped against.

BMW's own technical data gives 40.4 in of front headroom measured with the three-piece retractable hardtop raised — at the top of the convertible band, helped by the metal roof's more upright profile than a stowed fabric top allows.

42.2 in sits mid-band — enough for tall drivers on the standard power sport seats, and identical to the F32 Coupe since the two share the same front structure and 110.6 in wheelbase.

37.1 in of rear headroom with the hardtop raised is unusually good for a convertible 2+2 and near the top of the segment band — the folding steel roof preserves a taller rear roofline than a stowed soft top permits. Top down the measurement is moot.

33.1 in of second-row legroom is well clear of what a Mustang Convertible offers and genuinely usable for children or a short adult trip, but it is tight behind a tall driver and reviewers consistently name the rear seat as the car's practical limit.

BMW publishes the SAE trunk volume as a 7.8–13.1 cu ft range — the larger figure with the roof up is among the biggest in the convertible class and near the top of the band, but stowing the three-piece hardtop cuts it by 40%, so open-air motoring and luggage compete directly.

The 2019 car ships with BMW's 493 Storage Package, additional 12-volt sockets and a standard split fold-down rear seat that opens a genuine through-load path for skis or long items — but the cubbies themselves are small, there is no underfloor storage or onboard AC power, and the adjustable front armrest only arrives bundled with the $500 wireless-charging option. The bigger drawback is procedural: the cargo separator must be positioned before the roof will cycle, and reviewers describe retrieving anything from the trunk with the roof down as a multi-step automated process.

Sport seats and power front seats are standard on the 2019 430i Convertible and draw consistent praise for long-stint support, but lumbar adjustment is not standard on the volume car — it comes only inside the $1,100 Convenience Package or the M Sport Package (it is standard on the 440i). The two firm rear buckets are short-trip furniture, which is what keeps this out of the top band.

The standard suspension is well damped and composed over broken pavement, and the reinforced hardtop structure means only the most offset bumps produce any shake at all with the roof down. It falls short of plush because the standard 225/45 R18 run-flats transmit sharp impacts, and the optional Adaptive M Suspension in its firmer modes trades away comfort.

The insulated three-piece steel hardtop carries a noise-absorbing headliner that BMW credits with up to 2 dB less wind noise than the predecessor's, making this one of the quietest convertibles of its era with the roof up, and the standard wind deflector keeps top-down buffeting low. Run-flat road noise is the main intrusion, so it is quiet for a drop-top rather than quiet outright.

Automatic climate control and ambient lighting are standard, and BMW offers the genuinely convertible-specific $500 Neck Warmer that blows warm air from the headrests to extend top-down season — but the comfort content buyers actually shop for is all extra-cost on the volume 430i: heated front seats are $500 or bundled in the $1,100 Convenience Package, the heated steering wheel is another $190 and cannot be ordered without one of those, and no ventilated seats exist at any price.

BMW's own MY2019 pricing guide opens the 4 Series Convertible at $52,950 for the rear-drive 430i, plus a $995 destination and handling charge — $53,945 delivered, already past the $55,000 top of the convertible normalization band before a single option box is ticked.

The all-wheel-drive 430i xDrive is the volume US configuration at $54,950 + $995 destination, and BMW's à-la-carte structure pushes real transactions higher: heated seats and blind-spot detection are only available inside the $1,100 ZCV Convenience Package, and any color but Alpine White or Jet Black is $550 — content essentially every four-season convertible buyer specifies.

Published 4 Series cost-to-own data puts five-year scheduled maintenance near $3,000 and repairs near $3,100, and RepairPal's BMW-brand average of $968/yr with 0.9 shop visits per year — more than twice the industry rate — corroborates that order of magnitude. The figure is nudged above the class estimate because the F33's power three-piece retractable hardtop is a heavy multi-motor mechanism the coupe-derived class data does not price in. BMW Ultimate Care covers the first 3 years/36,000 miles of scheduled service, so most of this spend lands in years 4–5.

KBB's observed valuations bracket the five-year point directly: the 2019 430i Convertible was worth about $28,200 at four years old and is worth $18,350 now at seven, a straight-line loss of roughly six points of original MSRP per year that puts the five-year mark near 46%. That is well short of the ~52–54% the 4 Series line as a whole is credited with, because the drop-top depreciates harder than the coupe and this one carries a body BMW replaced in 2021.

BMW's New Vehicle Limited Warranty covered 2019 models bumper-to-bumper for 4 years or 50,000 miles — a year longer than the mainstream 3/36 standard and the normal term across the German luxury field, though the 50,000-mile cap binds before the fourth year for most drivers.

BMW publishes no powertrain coverage beyond its bumper-to-bumper term, so the engine and drivetrain of a 2019 430i Convertible are protected for the same 4 years/50,000 miles — under the 5-year floor where the segment band even begins, and less than half the 10-year terms some mainstream brands advertise.

BMW Ultimate Care bundles 3 years/36,000 miles of complimentary scheduled maintenance — oil and filter, brake fluid, spark plugs, cabin filter and inspections — with 4 years of unlimited-mileage roadside assistance, BMW TeleServices, and standard ConnectedDrive Services and Remote Services. That sits at the strong end of the luxury field, where several rivals include only a first visit. It falls short of the top band because wear items such as brake pads require the paid Ultimate Care+ upgrade, and 2019 shipped Apple CarPlay on a one-year trial with an $80/yr renewal — a fee BMW only cancelled, retroactively, in December 2019.

$57,600 volume-trim price minus its estimated resale value after 5 years (46% retained, or about $26,496) leaves about $31,104 in depreciation. Add the projected $6,400 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $37,504 in total.

Signals are mixed and mid-pack at best: J.D. Power rated the 2019 430i 4/5 for Quality & Reliability, while Consumer Reports' own 2019 4 Series page flags it as less reliable than the average 2019 car, with owner-survey trouble spots concentrated in electrical systems plus transmission, cooling and the convertible top. 2019 is the sixth year of the mature F32/F33 generation, which normally earns a maturity credit, but the three-piece retractable hardtop adds a failure mode the coupe does not carry and it shows up in the survey data.

BMW is the strongest of the German luxury brands in recent multi-year dependability data — J.D. Power 2024 VDS 9th overall at 190 PP100 (3rd among luxury behind Lexus and Porsche), 2025 VDS 189 PP100 versus Mercedes 243 and Audi 273, and #1 luxury in the 2025 Consumer Reports brand report card. It still trails the Japanese leaders and its 2025 Initial Quality Study result (196 PP100) sat below the 192 industry average, so short of a top-tier 85+.

Three NHTSA recalls cover the 2019 4 Series, and one is a driveability-safety item rather than paperwork: 18V-465 for engine stalling (5,309 units), 19V-352 for an improperly folded knee airbag (5,079 units), and 18V-533 for a passenger frontal airbag inflator (a 3-unit campaign). The 2019 model year sits just outside BMW's large 24V-608 electric coolant-pump fire recall, which stopped at 2018. TSB and independent-shop patterns for the F33 add hardtop hydraulics (snapped fluid lines, pump failure, latch faults), blocked roof drains causing water ingress, and the generation's usual oil filter housing and valve cover gasket leaks.

The volume 430i runs the B46 2.0L turbo four — the US-market sibling of the B48 — paired with the ZF 8HP automatic, and both are well-proven: the B46/B48 family is a clear step up from the troubled N20 it replaced, with no timing-chain weakness and no systemic failure trend, and the 8HP is the segment's durability benchmark. The 440i's B58 straight-six is among BMW's most durable modern engines. Deductions are for the family's well-documented consumables — coolant leaks, oil filter housing and valve cover gaskets, water pump — which are maintenance-grade rather than catastrophic.

The F33 LCI cabin is solidly premium — standard SensaTec with available Dakota leather, real metal and wood trim on higher lines, and switchgear that still feels dense — but by 2019 the F32-generation design was five years old and reviewers consistently placed it behind the newer Audi A5 Cabriolet and Mercedes C-Class Cabriolet on material richness and cabin design. Hard plastics remain in the lower dash and lower door zones at a price point where rivals had moved on.

Assembly is a strength: the F33 was in its sixth production year at BMW Dingolfing with the tooling long settled, and reviewers and owners call out excellent fit and finish with tight panel gaps and few chronic rattles. The retractable metal hardtop seals far better than a fabric roof and keeps cabin noise and water intrusion down when the drains are clear, though a folding-roof convertible inevitably carries more structural shake and seal-alignment exposure than the coupe.

BMW ran roughly 340 US retailers in 2019 (about 370 today) with dense metro and suburban coverage and a deep independent-specialist network behind it, which matters more for a now-used car. Service satisfaction is only adequate: BMW has posted at-or-above-average results in J.D. Power's premium Customer Service Index but finished last among luxury brands in the 2025 ACSI auto study at 75. Rural coverage is thinner than a mainstream brand's.

Availability is genuinely good — OEM channel plus one of the largest enthusiast aftermarkets in the business (FCP Euro, ECS Tuning, Turner) — but cost is where this car loses. RepairPal ranks BMW 30th of 32 brands at 2.5/5 with ~$968 average annual maintenance against a ~$652 industry average, and the closely related 428i sits at ~$1,229/yr. The F33's hydraulic three-piece hardtop is the aggravating factor: pump and fluid-line failures are effectively dealer or specialist work with no cheap fix, and blocked-drain water damage compounds it.

2019 is the year the navigation system became standard equipment on the US 4 Series Convertible, which promotes every car from the 6.5-inch base display used through 2018 to the 8.8-inch touch-capable iDrive screen. It is still small by 2019 standards — the F33's hardware dates to the 2014 launch and nothing larger was ever offered in this body.

iDrive 6.0 on NBT EVO is one of the best-executed systems of its generation: a fast live-tile interface driven by the console rotary controller with handwriting pad and programmable shortcut buttons, plus touch input on the now-standard 8.8-inch screen, and real physical climate and audio keys underneath. It loses points only for a learning curve reviewers still flag and for looking dated against the iDrive 7 systems arriving on BMW's newer platforms that same year.

Wireless Apple CarPlay is standard equipment on the 2019 car — ahead of the wired-only projection most rivals shipped — but as sold it carried only a one-year trial and an $80/year subscription after that, a charge BMW cancelled retroactively in December 2019 so surviving cars now have it permanently. Android Auto is simply absent: BMW did not offer it until mid-2020 and only on iDrive 7 hardware the F33 never received, so half of phone owners get nothing.

For 2019 BMW Navigation is standard rather than optional, and it ships with Advanced Real-Time Traffic Information as standard too — genuinely good native mapping that no longer costs extra. Voice control is the pre-iDrive-7 command-word generation, reliable for addresses and contacts and backed by a handwriting pad, but not conversational: BMW's natural-language Intelligent Personal Assistant launched with iDrive 7 and never reached this platform.

The volume 430i Convertible ships with BMW's Hi-Fi sound system plus HD Radio, which is a competent base for the class, and the Harman Kardon surround system is a well-regarded $875 upgrade (standard on the 440i). It stays out of the top band because that upgrade cannot be ordered à la carte — it requires the Convenience or M Sport Package first — and convertible acoustics fight any system with the roof down.

The volume car runs analog dials with BMW's 'instrument cluster with extended contents' — a colour info panel between conventional gauges, not a reconfigurable display. The 6WB Dynamic Digital Instrument Cluster exists for 2019 at a nominal $350, but it can only be ordered on top of the $2,550 Executive Package, which itself requires the Convenience or M Sport Package, putting roughly $4,000 of prerequisites in front of a $350 item. A standard digital cluster did not arrive until the G23 second generation.

The NBT EVO head unit behind iDrive 6.0 supports over-the-air map updates through BMW ConnectedDrive and nothing beyond that. BMW's Remote Software Upgrade, which pushes whole-vehicle feature updates, launched with iDrive 7 and was never back-ported to this generation, so every other software change means a dealer visit.

For 2019 the whole connected bundle is standard rather than package-gated — Remote Services (lock/unlock, vehicle finder, vehicle status, send-to-car), ConnectedDrive Services, BMW Assist eCall and TeleServices all ship on the base 430i, with a Wi-Fi hotspot arriving alongside the wireless-charging option. It is held mid-band because there is no remote engine start on this generation, no digital key (BMW's NFC phone key launched in 2020 on newer hardware), and services lapse into subscriptions once the included term ends.

Device power is the car's weakest technology area: a standard hands-free Bluetooth and USB-A audio connection plus additional 12-volt sockets, nothing at all for rear passengers, no USB-C anywhere on this platform, and no household outlet. Wireless phone charging is a $500 option that cannot be ordered without the Convenience or M Sport Package.

Comfort Access proximity entry is a no-charge item fitted by default on the 2019 430i Convertible (outright standard on the 440i) — which on this body also allows the roof to be cycled from the fob — alongside standard push-button start, an alarm system and a universal garage-door opener. What holds it mid-band is what does not exist on this platform at any price: no remote engine start and no phone-as-key.

A rearview camera and front-and-rear Park Distance Control are both standard for 2019, which covers the everyday case on a car whose top-up rear sightlines need the help. The better hardware — side and top-view cameras and the self-parking Parking Assistant — is locked inside the $2,550 Executive Package, which itself requires another package first, so surround view is a roughly $3,650 proposition.

BMW's full-colour head-up display is orderable on the volume 430i Convertible as a stand-alone $1,100 option with no package prerequisite — one of the better implementations of its era, showing speed, navigation and speed-limit data crisply. Optional rather than standard, and at that price rarely ticked, which holds it to the middle band.

A two-door 2+2 with no rear doors makes every child-seat installation a matter of tilting and sliding a front seat and reaching over a high sill, and with the hardtop raised the low roof opening makes leaning in awkward. Two rear positions is the hard ceiling, and the stroller that fits the 13.1 cu ft trunk stops fitting the moment the roof is stowed and capacity drops to 7.8.

2019 is the weakest year of this generation for a family buyer: the 430i Convertible leaves the lot with no active-safety content at all — forward collision warning, city collision mitigation, pedestrian warning and lane departure warning are all inside the $500 Driving Assistance Package, blind-spot detection is another $500, and adaptive cruise $1,200. (BMW made Active Driving Assistant standard only for 2020.) Compounding it, neither NHTSA nor IIHS ever crash-tested this body, so there are no independent crash credentials to lean on either.

Better than most convertibles for a family — 33.1 in of rear legroom and 37.1 in of rear headroom with the top up genuinely seat two children, and the insulated hardtop keeps the cabin quiet enough for long stints. But there are no rear amenities whatsoever (no rear vents, no rear USB or 12V for the back seat) and four people's luggage does not fit alongside a stowed roof.

The 248-hp turbo four with 258 lb-ft from 1,450 rpm and the standard ZF eight-speed make low-speed traffic effortless, the ride is well damped, and the three-piece roof drops in about 20 seconds at up to roughly 11 mph so the open-air option costs nothing at a stoplight. The recurring annoyances are the auto stop/start restart and restricted over-the-shoulder visibility with the hardtop up.

27 MPG combined is respectable for a 4,037-lb retractable-hardtop convertible, but every mile burns required premium and EPA puts the annual bill at about $2,800 — and the standard run-flat tires are an expensive, frequently replaced consumable on a brand RepairPal ranks near the bottom for repair cost. Average-at-best commuting economics for the class.

A compact 182.7 in footprint and a 37.1 ft curb-to-curb turning circle make city work genuinely manageable, and a rearview camera plus front-and-rear parking sensors are standard for 2019. Working against it: thick rear quarters and a shallow backlight with the hardtop up, and the surround-view cameras and self-parking that would fix that are locked behind the $2,550 Executive Package.

There is no work case here at all: no US tow rating, no bed, no meaningful payload headroom, and a trunk that shrinks to 7.8 cu ft the moment the roof is stowed. A luxury two-door convertible is the opposite of a work tool.

The B46 turbo four and ZF 8HP driveline are durable enough in ordinary use and the F3x platform is well proven, but nothing else about the car suits abuse — leather or SensaTec and soft-touch surfaces throughout, low-profile run-flats, 5.1 in of ground clearance, and a complex three-piece powered hardtop whose seals and hydraulics are an expensive failure point rather than a fleet asset.

No onboard AC power, no bed or tie-down system, no factory hitch, no roof-rack possibility on a retractable hardtop, and no washable surfaces or upfit ecosystem of any kind. The only work-adjacent provision on the car is a pair of 12-volt sockets.

This is the car's strongest mission after commuting: a well-isolated hardtop cabin, standard sport seats reviewers call good for hours, a composed highway ride and roughly 427 miles from the 15.8-gallon tank at 27 MPG. It stops short of the top band because the fatigue-reducing driver assistance is entirely optional on the 2019 car — adaptive cruise is a $1,200 box and the volume car ships with plain Dynamic Cruise Control — and rear occupants will want out well before the fuel does.

xDrive all-wheel drive is available for $2,000 and makes the car usable in bad weather, which is the whole of its outdoor credential. Ground clearance is 5.1 in, the tires are low-profile run-flats, there is no tow rating and no roof-rack possibility on a folding metal roof, and nothing in the packaging supports camping or gear hauling.

13.1 cu ft is a genuinely useful convertible trunk and the split fold-down rear seat is standard for 2019, so long items can pass through into the cabin without paying for an option. But the trunk opening is shallow and segmented, the cargo separator needed to stow the roof cuts capacity to 7.8 cu ft, and there is no roof rail, hitch or underfloor storage to fall back on for anything bulky.

Quick steering, a near-53% rear weight bias and a heavily reinforced open structure give the F33 secure, composed cornering with essentially no scuttle shake, and the optional M Sport or Adaptive M suspension tightens it further. It cannot reach the top band because 4,037 lb of curb weight and a higher center of mass blunt the agility the F32 Coupe finds on the same platform.

The electric rack is accurate and direct with sharp turn-in, and the drive-mode weighting is sensibly judged — lighter in Comfort and Eco Pro, meaningfully heavier in Sport. Reviewers of this generation are consistent that it is numb by BMW's own historical standard: precise enough, but short on the feedback that separates good steering from great.

Ventilated discs at all four corners with BMW's well-tuned pedal give firm, progressive response and repeatable stops from highway speed, and the stiff-sidewall run-flats contribute short, stable stopping distances. Unlike 2020, M Sport Brakes were still orderable on the 2019 Convertible for buyers who want more fade resistance. No instrumented figure specific to the 2019 Convertible was located, which caps the confidence rather than the score.

The 2.0-liter turbo's 258 lb-ft plateau from 1,450 rpm makes it feel effectively lag-free, and the standard 8HP50 Sport Automatic is the benchmark torque-converter automatic of the era — quick, decisive and sensibly calibrated with no hunting across eight ratios. The one persistent complaint is the standard auto stop/start restart, unsmoothed by any 48V system on this generation.

The four-cylinder is smooth and well isolated, and with the roof down the engine note is pleasantly audible rather than intrusive thanks to low wind noise. It is acoustically ordinary next to the B58 inline-six in the 440i — competent and inoffensive rather than a reason to drop the roof.

BMW's own technical data gives 37.1 ft for the rear-drive 430i Convertible and 38.7 ft for the xDrive models, whose front driveshafts cost about a foot and a half of agility. Mid-band for the segment — compact enough for city work but no better than an ordinary sedan.

Standard power sport seats and a multifunction wheel give a low, well-adjustable driving position, and iDrive's rotary controller alongside retained physical climate and audio keys makes the cabin easy to work without looking away from the road. It falls short of the top band on sightlines: with the hardtop raised the thick rear quarters create real over-the-shoulder blind zones, and the low sills make ingress and egress a drop rather than a step.

Roof down on a good road the 430i Convertible is genuinely enjoyable — rear drive, a willing turbo four, 20 seconds to open sky at up to 11 mph. But the tuning is deliberately grand-touring: reviewers describe it as a comfortable cruiser rather than a backroad car, delivering pace without much involvement, and the four-cylinder soundtrack does not compensate.

2019 was the year BMW backfilled the obvious gaps: navigation, front and rear parking sensors, an upgraded instrument cluster and an Apple CarPlay trial all became standard, joining the power retractable hardtop, 10-way power sport seats, Comfort Access keyless entry, dual-zone automatic climate, LED headlights and fog lights, ambient lighting and a standard wind deflector. It is still unmistakably German à-la-carte, though: on a $53,945 convertible, heated seats and blind-spot detection are locked inside the $1,100 Convenience Package, every active-safety feature is a $500 option, and adaptive LED headlights, parking cameras and Harman Kardon audio are all extra-cost.

Fair rather than generous. $53,945 buys a 248-hp four-cylinder and a folding hardtop, and a Mustang GT Convertible delivers roughly double the horsepower for well over $10,000 less. Within the luxury drop-top set the pricing is level with the Audi A5 Cabriolet and Mercedes C 300 Cabriolet and the BMW out-drives both, but the underlying hardware — a 2013-vintage platform running iDrive 6.0 — was visibly a generation behind what rivals were fielding by 2019, and the à-la-carte option structure means a representative car lands near $58,000.

Six factory configurations of the convertible body alone — 430i and 430i xDrive with the 248-hp four, 440i and 440i xDrive with the 320-hp six, and the rear-drive M4 Convertible in standard and Competition tune — spanning roughly $54,000 to $82,000, with rear- or all-wheel drive available at both mainstream power levels and one of the deepest package and trim-line catalogues in the segment above that.

18,621 US deliveries across all three 4 Series bodies is still real volume for a $50k-plus two-door line, but the trajectory is the problem: down 40.7% from 2018 and less than half the 2017 peak, in a year when BMW brand sales overall were roughly flat. Buyers were moving to SUVs and the market had begun discounting a body that was plainly nearing replacement, and the slide continued into 2020.

BMW is a top-tier aspirational badge with a loyal following, and the roundel does real work on a car bought substantially for image. The F33 in particular has aged well: it is the last 4 Series with a conventional kidney grille and the last with a folding hardtop, both of which read as advantages in hindsight against the polarizing G23 that replaced it, and owner sentiment for the 2019 car is strong.

A good year to negotiate. By 2019 the F33 was in its sixth model year with volume down 41%, which gave dealers real motivation on stock, and BMW supported the line with subvented lease programs plus stackable loyalty, military and college-grad bonuses. It falls short of the top band only because the replacement had not yet been revealed — the open clearance pricing arrived in 2020 — so the discounts were healthy rather than exceptional.

Mid-to-late life. 2019 is the sixth model year of the F32/F33 generation launched for 2014, and only one year past the MY2018 LCI facelift that brought restyled LED lighting, revised bumpers, retuned suspension and the tile-interface iDrive — so the car was recently freshened even though the platform was not. The successor was not yet public during the 2019 selling season (BMW showed the Concept 4 in September 2019 and launched the G22/G23 in mid-2020), but a 2013-vintage architecture running iDrive 6.0 was audibly older than the 3 Series sedan it shared a showroom with, which had just been redesigned as the G20 for 2019.

Well-reviewed but never the pick of the class. Critics consistently praised the chassis balance, engine range and build quality — the 4 Series is routinely called one of the best-driving convertibles in its set — and owner satisfaction is high, but the aggregate verdict by 2019 was that it no longer held a clear edge over the Audi A5 Cabriolet or Mercedes C-Class Cabriolet, and it placed mid-pack in class rankings. The F32/F33 generation collected no 10Best, NACTOY or IIHS Top Safety Pick honors.
