2023 BMW 4 Series

Volume 2023 430i Coupe (pre-LCI G22) uses BMW's B48 2.0L turbo I4 at 255 hp (no 48V MHEV on the 430i until the 2025 LCI); the range steps up through the M440i's 48V mild-hybrid B58 inline-six at 382 hp, the S58-powered M4 (473 hp manual), M4 Competition (503 hp RWD or xDrive), and the limited-run 2023 M4 CSL at 543 hp.

The 2023 430i's B48 delivers 295 lb-ft on a broad ~1,600 rpm plateau; M440i's B58 with 48V mild hybrid raises it to 369 lb-ft, the M4 manual to 406 lb-ft, and M4 Competition/CSL peak at 479 lb-ft.

BMW quotes 5.5 s for the 2023 430i RWD Coupe and 5.3 s for xDrive; M440i xDrive drops to 4.3 s, M4 Competition xDrive to 3.4 s, and the limited 2023 M4 CSL to 3.6 s — competitive at each price step.

The B48 in the 2023 430i is among the smoothest turbo fours in the segment with negligible lag and linear delivery (auto-stop is the only rough note pre-MHEV); the M440i's 48V mild-hybrid B58 inline-six is a benchmark for refined performance, and the S58 in the M4 is a hard-edged but throttle-responsive high-strung six.

The ZF 8HP 8-speed Steptronic remains the segment benchmark — crisp, decisive shifts with excellent manual paddle response; the reinforced 8HP in the M4 approaches dual-clutch speed, and the standard 6-speed manual in the base 2023 M4 is one of the last remaining true 3-pedal options in a modern sports coupe.

xDrive is a low-cost option on the 2023 430i, standard on the M440i, and standard on the M4 Competition xDrive; the rear-biased multi-plate clutch system integrates with M Traction Control on the M cars. Base M4 manual, M4 Competition RWD, and the M4 CSL remain rear-drive only.

Three distinct engines across the 2023 range — B48 2.0T (430i), B58 3.0T 48V mild-hybrid inline-six (M440i), and S58 3.0T twin-turbo six (M4/Competition/CSL) — cover efficiency, mainstream luxury, and full performance. No PHEV or EV variant in the G22 Coupe body (BMW reserves electrification for the separate i4 Gran Coupe), keeping this below the 3 Series which offers the 330e PHEV.

EPA combined for the 2023 430i xDrive Coupe (pre-LCI G22) with the non-MHEV B48 2.0L turbo I4. RWD 430i posts 29; the 48V mild-hybrid M440i falls to 25, and the S58-powered M4 Competition drops to 19.

EPA city rating for the 2023 430i xDrive Coupe with auto stop-start (no MHEV on the base 430i pre-2025 LCI); RWD 430i nudges to 26 city, and the M4 Competition drops to 16.

EPA highway rating for the 2023 430i xDrive Coupe; RWD posts 34, M440i drops to 30, and M4 Competition to 23.

Computed from BMW's 15.6-gallon fuel tank and EPA combined 28 MPG for the 2023 430i xDrive. 430i RWD stretches to ~452 mi at 29 MPG; the M4 falls to roughly 300 mi in mixed driving at 19 MPG.

EPA-published annual fuel cost for the 2023 430i xDrive Coupe at 15,000 mi/yr, 55/45 city/highway split, on premium unleaded. Reflects the higher 2022–2023 EPA premium-fuel benchmark relative to later model years; M440i climbs above $3,100 and M4 Competition above $3,900.

Every 2023 4 Series Coupe variant — 430i, M440i, M4, M4 Competition, and the limited M4 CSL — requires premium unleaded (91 octane or higher) per BMW's owner's manual and window sticker; no regular-fuel option, no flex-fuel, and no home-charging alternative in this body style.

NHTSA has not comprehensively rated the 2023 BMW 4 Series Coupe body style; estimate is derived from the shared CLAR-platform 3 Series sedan, which has earned 5-star NHTSA overall in recent testing.

The G22 4 Series earns Good ratings on legacy IIHS crashworthiness tests (moderate overlap front, small overlap front) but is not on the 2023 IIHS Top Safety Pick list, reflecting the updated side-impact and pedestrian-AEB protocols where results have been Acceptable rather than Good.

BMW Active Driving Assistant is standard on all 2023 4 Series trims — forward collision warning with city collision mitigation/AEB, blind-spot detection, lane departure warning, rear cross-traffic alert, and park distance control. Full-speed adaptive cruise with stop-and-go and lane centering remain part of the paid Driving Assistance Professional Package, trailing Lexus RC's standard LSS+ and Mercedes CLE's broader standard suite.

BMW's front collision prevention has earned Superior daytime and Advanced/Superior nighttime pedestrian ratings on the shared-platform 3 Series; the 2023 4 Series uses the same camera + radar sensor suite and expected performance carries over, though not separately IIHS-rated for pedestrian AEB.

Blind-spot detection and rear cross-traffic alert are standard across the 2023 4 Series lineup as part of Active Driving Assistant; intervention is alert-only, without active steering correction on the volume 430i trim.

Lane departure warning is standard; active lane keeping and lane centering come with the Driving Assistance Professional Package. When equipped, BMW's centering is well-regarded for smooth tracking with minimal ping-ponging per reviewer testing of the pre-LCI G22.

The optional Driving Assistance Professional Package adds full-speed-range adaptive cruise with stop-and-go and an integrated Highway Assistant; BMW's calibration (smooth braking, quick resume, natural gap-keeping) is among the best in class. Points off because the full system is not standard on the volume 430i.

BMW Highway Assistant enables hands-free driving up to 40 mph on divided US highways in traffic with driver eye monitoring, offered on the 2023 4 Series via the Driving Assistance Professional Package (broader speed-range coverage came with a later software update). Mapped-road coverage is narrower than GM Super Cruise's network but the system is mature and available.

The 2023 4 Series uses standard LED headlights with automatic high beam; adaptive LED headlights are optional and typically bundled with upper trims. IIHS testing on the pre-LCI G22 4 Series showed Acceptable on volume-trim headlights, Good only with the adaptive units.

Classic coupe compromise — thick B/C-pillars, low roofline, high beltline, and a small rear window restrict natural sightlines. A standard reversing camera and available 360-degree Parking Assistant Plus help, but reviewers consistently flag rear visibility as a weak point.

The two-door 2+2 configuration forces child-seat installation through a single narrow doorway after tumbling the front seat; LATCH anchors are recessed under upholstery and rear-seat width is limited. Not a practical family carrier.

BMW USA lists the G22 4 Series Coupe (430i/M440i volume trims) for 2023 with a rear bench and 5-passenger seating; the raised transmission tunnel and sloping roof make the center rear position a token spot in practice. M4 with optional M Carbon buckets is 4-seat.

BMW-published front headroom for the G22 4 Series Coupe — unchanged since the G22 launch and identical for 2023; moonroof-equipped cars give up roughly 1.9 in.

BMW-published front legroom for the G22 4 Series Coupe — competitive for a compact luxury coupe and comfortable for taller drivers thanks to the long 112.2-in wheelbase. Unchanged for 2023.

Rear headroom of 36.6 in is mid-pack for the coupe segment — usable for shorter adults on shorter trips and clearly better than the smaller 2 Series (35.0 in), though the fastback roofline still constrains taller passengers.

Rear legroom of 34.0 in is tight but usable — meaningfully better than the 2 Series Coupe's 32.2 in and adequate for adults on short trips behind average-sized front occupants.

BMW USA lists 12.0 cu ft of trunk volume for the G22 4 Series Coupe — smaller than the 2 Series (13.8 cu ft) despite the larger footprint because of the tapered fastback shape, but the standard 40/20/40 folding rear seat with ski passthrough expands the load bay for longer items.

Typical BMW cabin storage: modest covered console, small door bins with bottle holders, front cupholders, and a 40/20/40 folding rear seat with ski passthrough. For 2023, wireless charging remains a Premium Package option, so base cars have fewer built-in device-management features than later refreshes.

Standard 14-way power sport seats with adjustable side bolsters, thigh extension, and available Vernasca leather earn consistent praise for long-haul support up front; the rear bench is firm but well-shaped for the space and better than most compact coupes at accommodating an adult on shorter drives.

The G22 4 Series rides more compliantly than the smaller 2 Series thanks to its longer wheelbase and more sophisticated damping; base 2023 430i with standard suspension is notably smoother than M Sport-package cars on 19-in wheels, which trade some pliancy for tighter body control.

Standard acoustic windshield, thick body sealing, and refined B48/B58 powertrains keep highway cruising civilized — measurably quieter than the 2 Series and among the more hushed compact luxury coupes at 70 mph. Some tire roar on M Sport rubber remains the primary intrusion.

Standard dual-zone auto climate and heated front seats on all 2023 trims; heated steering wheel and wireless charging bundled in the Premium Package, and ventilated front seats plus heated rear seats optional on M440i and up. Well-equipped for the class but a step behind rivals that make the heated wheel/wireless charging standard.

The 2023 430i Coupe RWD (B48 2.0T turbo-4, 255 hp) is the base trim at $49,795 plus $995 destination. This is the third model year of the G22 4 Series (2021–2024 pre-LCI), with only minor equipment/pricing changes vs. 2022; the mid-cycle refresh with the Curved Display and iDrive 8.5 arrived for 2025.

The volume build is the 430i xDrive Coupe ($51,795 + $995 destination = $52,790) fitted with the near-mandatory Premium Package (~$2,600: heated seats, keyless entry, moonroof, wireless CarPlay/Android Auto) plus common Convenience/M Sport wheel add-ons — typical 2023 transaction lands in the mid-$56K range, well above the coupe segment mainstream.

German luxury coupe economics: dealer labor rates, run-flat tires, synthetic oil intervals, and turbocharged B48/B58 servicing push 5-year maintenance + out-of-warranty repair to the top of the coupe segment band. With no complimentary scheduled maintenance in MY2023 (Ultimate Care was reinstated only for MY2025), owners pay out-of-pocket from day one for oil, brake, and tire service.

BMW mid-size luxury coupes depreciate faster than Japanese luxury peers because heavily-optioned MSRPs don't hold up on the used market and the coupe body style has softer resale than the 3 Series sedan sibling. 2023 models bought at the tail of the post-COVID pricing peak have taken a slightly steeper hit than 2024s; M440i variants retain 3–5 points better than 430i.

BMW's New Vehicle Limited Warranty is 4 years or 50,000 miles, whichever comes first. Standard among German luxury (matches Audi and Mercedes; trails Genesis/Jaguar 5-yr).

BMW does not publish a separate extended powertrain warranty; the powertrain is covered under the same 4-yr/50k New Vehicle Limited Warranty. Well below the segment band floor of 5 years and dwarfed by Hyundai/Kia/Genesis 10-yr/100k coverage.

BMW dropped its Ultimate Care complimentary scheduled maintenance program starting MY2020 and did not reinstate it until MY2025 — so 2023 4 Series buyers get just 4-yr/unlimited-mile roadside assistance plus a modest BMW ConnectedDrive/eCall trial. Weak vs. peers: Genesis (3 yr / 36k service), Jaguar EliteCare, Volvo, and Cadillac all offered multi-year included maintenance in this window. No included charging/fuel credits (gas-only).

$56,400 volume-trim price minus its estimated resale value after 5 years (45% retained, or about $25,380) leaves about $31,020 in depreciation. Add the projected $9,300 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $40,320 in total.

The pre-LCI G22 4 Series is in its third model year for 2023, with Consumer Reports predicted reliability tracking around Average and J.D. Power quality scores for the model in the low-80s. Hardware is the well-known B48 2.0T / B58 3.0T + ZF 8HP shared with the 3 and 2 Series, and 2023 carries no new-electronics risk (no LCI, no curved-display iDrive 8.5).

BMW consistently sits in the upper-middle of dependability rankings — solid but well behind the Japanese leaders. J.D. Power 2023 VDS places BMW slightly above industry average behind Lexus/Genesis/Toyota, and Consumer Reports 2023 brand reliability ranks BMW around 10th of ~24 ranked brands. Best of the German premium set alongside Porsche.

Through 2023 the G22 4 Series has accumulated typical recall activity — backup camera image display, seatbelt anchor, occupant classification sensing, and assorted software campaigns — but no systemic powertrain, fire, or braking actions. TSB volume is in line with segment norms for a BMW model.

The 430i's B48 2.0T (post-2019 revision) and the M440i's B58 3.0T inline-six with 48V mild hybrid are among BMW's most durable modern engines — the B58 in particular has an outstanding high-mileage reputation (also chosen by Toyota for the GR Supra) and pairs with the industry-benchmark ZF 8HP automatic.

The 2023 pre-LCI cabin uses SensaTec/leatherette or optional Vernasca leather, aluminum or wood trims, and a split 12.3-inch digital cluster + 10.25-inch center display — competitive materials for the low-$50K luxury coupe class though the dashboard look-and-feel is a step behind the incoming LCI update and behind the Mercedes CLE Coupe on perceived richness.

Assembly at BMW's Munich plant produces tight, consistent panel gaps and solid door thunk with low rattle rates in early ownership; iDrive 8 in the 2023 car is largely bug-free by this point in the generation. Not quite Lexus-level flawless but strong for the class.

Roughly 340 BMW dealers spread across all 50 states provide strong nationwide coverage in metro and suburban markets, thinner in rural areas; luxury service satisfaction sits in the upper-middle of the segment behind Lexus and Cadillac but ahead of Audi and Mercedes in recent surveys, though hourly labor rates are among the industry's highest.

OEM parts are readily available through BMW's US supply chain and the 4 Series has healthy enthusiast aftermarket support (FCP Euro, ECS Tuning, Turner), but out-of-warranty ownership cost is notably above segment average — synthetic oil, run-flat tires, expensive brake service, and dealer-only diagnostics push repair costs well beyond mainstream norms and above the luxury median.

2023 is a mid-cycle G22 year: the 4 Series carries the same 10.25" central Control Display paired with a 12.3" digital instrument cluster used since launch. The much larger 14.9" Curved Display did not arrive until the 2025 model year LCI.

2023 is the first full year of iDrive 8 across the 4 Series lineup; it is quick and logically laid out and the car retains the physical iDrive rotary controller alongside touch input — a big daily-usability plus. Early iDrive 8 had some menu depth and occasional bugs that reviewers noted before later software refinements, so it lands just below the 2024 tier.

Wireless Apple CarPlay and wireless Android Auto are standard on every 2023 4 Series Coupe trim (430i, 430i xDrive, M440i xDrive, M4, M4 Competition, M4 CSL) with no subscription. Pairing is quick and stable.

BMW Intelligent Personal Assistant ("Hey BMW") handles natural-language commands for climate, nav, and vehicle functions. BMW Maps with cloud-based routing and Real Time Traffic Information is standard; reviewers rate it capable enough to use in place of phone projection.

Standard 10-speaker Hi-Fi audio is adequate; optional Harman Kardon Surround Sound (464W, 16 speakers) bundled in the Premium Package is a meaningful upgrade and typical for the class. No Bowers & Wilkins tier available on the 4 Series.

12.3" fully digital instrument cluster is standard on all 2023 4 Series trims (Live Cockpit Professional). Crisp with multiple drive-mode layouts and integrated map view; not as visually integrated as the later Curved Display but still class-competitive.

BMW Remote Software Upgrade delivers periodic OTA updates covering iDrive, maps, and select vehicle functions via the embedded modem or My BMW app. Scope is narrower than Tesla/Rivian whole-vehicle updates but broader than maps-only rivals.

My BMW app covers remote start/climate, lock/unlock, vehicle location, and BMW Digital Key Plus (Ultra Wideband) for compatible iPhone devices. Core ConnectedDrive functions free for the first several years of ownership.

Two front USB-C ports and rear USB-C outlets standard; wireless phone charging tray is bundled in the Premium Package rather than standard. Adequate for the segment; no 120V outlets.

Comfort Access keyless entry with push-button start is standard on M440i/M4 and available on 430i via the Convenience or Premium Package. BMW Digital Key Plus (UWB) is available and rare at this price. Remote start via My BMW app included.

Rear-view camera and Park Distance Control (front and rear sensors) are standard; optional Parking Assistant Plus adds Surround View with 3D visualization and automated parallel/perpendicular parking. Image quality is good if not class-leading.

Full-color HUD projecting speed, nav directions, and driver-assist status is optional via the Premium Package on 430i and included within higher option groups on M440i/M4. Broadly attainable rather than volume-trim standard.

Two-door coupe with LATCH anchors at the outboard rear positions, but loading kids or car seats requires tipping a front seat forward every time. Rear legroom of ~34.0 in is slightly better than the 2 Series but still tight for rear-facing seats, making daily family logistics frustrating.

BMW's Active Driving Assistant (frontal collision warning with city AEB, blind-spot detection, lane-departure warning, active cruise) is standard across the 2023 range, but the 4 Series Coupe is a low-volume body that has not earned a current-generation IIHS Top Safety Pick and NHTSA does not publish a full 5-star crash rating for it.

12 cu-ft trunk and marginally better rear legroom than the 2 Series help, but the sloping coupe roofline compresses rear headroom, there are no rear-seat climate vents on standard trims, and four-up plus luggage is a squeeze for multi-hour trips.

2.0L turbo-four (M440i adds 48V mild-hybrid inline-six), ZF 8-speed, standard Active Driving Assistant and well-bolstered sport seats make the pre-LCI 4 Series a low-fatigue daily. The 10.25" central display with iDrive 7/rotary controller (some 2023 builds gained iDrive 8) trails newer rivals, and the firm ride on run-flats plus low seating position are minor drawbacks.

2023 430i RWD returns ~28 mpg combined and 430i xDrive ~27 mpg — competitive for a rear/AWD luxury coupe but requiring premium fuel. BMW consumables (run-flat tires, brake service, out-of-warranty maintenance) push per-mile cost above mainstream commuters, though the 3-yr/36k-mi Ultimate Care scheduled maintenance still applied to 2023 sales.

At ~187.9 in long and 72.9 in wide with a ~38.7 ft turning circle, the 4 Series is bigger and less nimble in tight parking than the 2 Series but still manageable in the city; standard rear-view camera plus Park Distance Control and optional Parking Assistant Plus with Surround View help. Coupe C-pillar creates over-shoulder blind spots.

Not rated for towing in the US market, no bed, no published payload, and only a 12 cu-ft trunk. Effectively no meaningful work capability.

Luxury-oriented interior with Sensatec/Vernasca leather trims, carpeted trunk, and no wash-out surfaces. BMW B48/B58 engines are durable in normal service but the car has no fleet reputation for hard-use work.

No cargo-area 120V outlet, no bed tie-downs, no factory trailer hitch, no roof-rack system on the coupe body, and no upfit ecosystem. Essentially zero work-oriented provisions.

Excellent front sport seats, quiet highway cruise, standard Active Driving Assistant with adaptive cruise and lane keep, and a 15.6-gal fuel tank giving ~430-mi highway range make the 4 Series a strong two-up tourer. Coupe roofline limits four-up endurance and rear amenities are thin.

xDrive AWD is available on 430i and standard on M440i and helps with snow and light gravel, but ground clearance of ~5.5 in, run-flat performance tires, no factory roof rack, and no factory hitch make it pavement-bound. Fine as a snow commuter; not a genuine adventure enabler.

12 cu-ft trunk is larger than the 2 Series and the 40/20/40 folding rear with center pass-through helps for skis and long items, but the small coupe aperture, absence of roof rails on the coupe body, and no factory hitch cap bulky-gear flexibility.

The G22 4 Series on BMW's CLAR platform delivers taut body control, near-50/50 weight distribution, and strong grip. Standard RWD or optional xDrive with a rear-biased split, an available Adaptive M Suspension, and stiffer bushings versus the 3 Series sedan give the Coupe a slightly sharper edge; the 2023 M440i xDrive posts roughly 0.91-0.93 g on the skidpad and M4 Competition xDrive climbs into the 1.0+ g range on summer rubber. The limited 2023 M4 CSL is the sharpest of the lineup with stiffer dampers, a wider track and 240 lb less mass than a Competition.

The 2023 430i and M440i use BMW's current electric power steering with a quick, accurate rack and well-judged weight, but on-center feedback is muted versus the brand's earlier hydraulic systems. The M4's Variable Sport Steering is more communicative in Sport mode though still short of best-in-class feel; the M4 CSL's revised rack is a touch more direct.

Standard brakes are strong with a firm, linear pedal — the 2023 M440i xDrive stops from 70 mph in the 155-160 ft range on all-seasons; M4 Competition xDrive with standard M Compound brakes has been measured near 140 ft on summer tires with excellent fade resistance. Optional M Carbon Ceramics are offered on the M4 and are standard on the 2023 M4 CSL.

BMW's B48 2.0T (430i) and B58 3.0T inline-six with 48V mild-hybrid assist (M440i) paired with the ZF 8HP 8-speed automatic set the class benchmark for drivability: prompt tip-in, minimal turbo lag, imperceptible shifts, and smoother stop/start thanks to the MHEV starter-generator on the M440i. The M4's S58 is more high-strung but still tractable with excellent throttle response; the base 430i lacks the 48V system so its auto-stop is a touch coarser than the M440i's.

The B58 inline-six sings with a rich, cultured tone under load and the B48 turbo-four is well isolated at cruise; the M4's S58 produces a harder, more mechanical note that some reviewers find less charismatic than the outgoing S55, though the 2023 M4 CSL's titanium exhaust adds welcome aural drama. Cabin sound is partly synthesized in Sport modes but background NVH is well controlled.

BMW USA specification sheet for the G22 4 Series Coupe lists a curb-to-curb turning diameter of approximately 38.7 ft on the 2023 430i/M440i — competitive for a compact luxury coupe despite the long 112.2 in wheelbase. M4 variants with wider front tires and different steering geometry are marginally larger.

Low, sporty seating with wide seat/wheel adjustment range and supportive standard sport seats; controls are logically placed and the standard rotary iDrive controller remains a strength. Rear over-shoulder visibility is compromised by the coupe roofline and thick C-pillars; the 2023 4 Series debuted the curved-display iDrive 8 which shifts more climate/audio functions to touchscreen submenus versus the previous system.

Rear-drive-biased chassis, strong balance, an eager B58 six in the M440i and the properly quick M4/M4 Competition make this one of the most engaging cars in its price bracket — and the 2023-exclusive M4 CSL (1,000 units globally, 543 hp, RWD, weight-cut) is a genuine collectible enthusiast halo. Press consistently recommends the M440i as a real driver's car, though the polarizing grille and slightly larger footprint versus the 2 Series cost a small amount of the classic 'small BMW' character.

The 2023 430i at ~$50k includes SensaTec upholstery with 8-way power sport seats, dual-zone climate, LED headlights, a 10.25" central display, 12.3" digital cluster, and the Active Driving Assistant ADAS bundle — but heated seats, keyless entry, moonroof, wireless Apple CarPlay/Android Auto, and Harman Kardon audio still live inside the Premium Package (~$2,600) or Convenience Package. Competitive rather than generous for the segment: a Lexus RC or Genesis G70 (four-door but cross-shopped) bundle more of that content at base.

The 2023 M440i xDrive at ~$59k delivers 382 hp from the B58 3.0T mild-hybrid inline-six, standard adaptive M suspension, xDrive, and M Sport differential — one of the strongest performance-per-dollar plays in the luxury coupe class versus the outgoing Audi S5 and pre-CLE Mercedes C-Class coupe. The 430i at ~$50k is fair rather than a bargain, trading standard content for BMW's benchmark chassis balance; the 2023 M4 Competition xDrive undercuts a Porsche 911 Carrera by tens of thousands with comparable straight-line pace.

The 2023 coupe body is offered as 430i RWD, 430i xDrive, M440i RWD (US-limited), M440i xDrive, then the separate M4, M4 Competition, and M4 Competition xDrive — plus the halo 2023-only M4 CSL (1,000 units globally, 543 hp, RWD, weight-cut). Add the 4 Series Convertible and 4 Series Gran Coupe siblings and the family covers a genuinely wide spread from ~$50k tourer to ~$140k collectible. Manual transmission remains on the standard M4 Coupe (a notable point of breadth versus most rivals) though not on the volume 430i/M440i.

The 4 Series was the best-selling two-door in BMW USA's 2023 lineup and one of the top-selling luxury coupes in the country, outselling both the 2 Series and 8 Series. Overall coupe segment volume has been shrinking as buyers migrate to SUVs and as Audi wound down A5 Coupe availability, so absolute numbers stayed modest — a steady mid-to-upper-pack seller in a contracting class.

BMW consistently ranks among the top-tier luxury brands with strong enthusiast credibility through the M sub-brand, and the 4 Series benefits directly from the M4 halo — amplified in 2023 by the M4 CSL. The polarizing large vertical kidney grille introduced with the G22 generation remains the most-cited critique of the model's image and does pull the score slightly below what a more conventionally styled BMW coupe would earn.

As the third year of the pre-LCI G22 generation, 2023 4 Series inventory transacted with meaningful (though not desperation) discounts — BMW Financial Services ran subsidized lease and low-APR programs on the 430i and M440i most months, with loyalty/college-grad cash stacking, and late-2023 leftovers moved at 4-6% below MSRP once the 2024s landed. The M4 and (especially) M4 CSL sold at or above sticker with no negotiation room. Better buyer economics than a Porsche or a fresh-launch Mercedes.

MY2023 is the third year of the G22 4 Series (launched MY2021) with no mid-cycle refresh yet — the LCI with the Curved Display, iDrive 8.5, revised styling, and 48V mild-hybrid across the range arrived only for MY2025. Not aging badly, but 2023 buyers face a known refresh looming two model years out, which softens future resale and dates the interior tech versus fresher rivals like the all-new 2024 Mercedes CLE.

The 2023 4 Series drew consistently positive reviews from Car and Driver, MotorTrend, Edmunds, and Road & Track for chassis balance, the B58 straight-six drivetrain, and the M440i's blend of pace and refinement. The 2023 M4 CSL earned universal acclaim as a modern M-division halo — Road & Track, Car and Driver, and Autoweek all singled it out — and the M4 Competition remained a frequent comparison-test podium finisher against Audi RS5 and AMG C63. Grille styling and shrinking coupe interest kept it off Car and Driver 10Best, but U.S. News, Edmunds, and Car and Driver Editor's Choice mentions placed it in the upper tier of luxury coupes.
