2025 BMW 4 Series

Volume 430i Coupe uses BMW's B48 2.0L turbo I4 with 48V mild hybrid at 255 hp; the range steps up through the M440i's B58 mild-hybrid inline-six, the S58-powered M4 (473 hp manual), M4 Competition xDrive at 523 hp, and the limited M4 CS at 543 hp.

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

BMW quotes 5.8 s for the 430i RWD Coupe and 5.5 s for xDrive; M440i xDrive drops to 4.3 s, M4 Competition xDrive to 3.4 s, and the M4 CS to 3.2 s — competitive at each price step.

The 48V-boosted B48 in the 430i is among the smoothest turbo fours in the segment — negligible lag, imperceptible auto-stop restart, linear delivery; the M440i's B58 mild-hybrid inline-six is a benchmark for refined performance and the S58 in the M4 is a hard-edged but 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 M4 is one of the last remaining true 3-pedal options in a modern sports coupe.

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

Three distinct engines across the range — B48 2.0T mild hybrid (430i), B58 3.0T mild-hybrid inline-six (M440i), and S58 3.0T twin-turbo six (M4/Competition/CS) — cover efficiency, mainstream luxury, and full performance. No PHEV or EV variant in the 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 2025 430i xDrive Coupe with the B48 2.0L turbo I4 and standard 48V mild-hybrid assist introduced with the 2024 LCI. RWD 430i gains ~1 MPG; M440i and the S58-powered M4 range fall well below the volume trim.

EPA city rating for the 430i xDrive Coupe with 48V MHEV auto-stop assist; RWD nudges a tick higher.

EPA highway rating for the 430i xDrive Coupe with the mild-hybrid B48; RWD 430i posts 34.

Computed from BMW's 15.6-gallon fuel tank and EPA combined 28 MPG for the 430i xDrive. 430i RWD stretches to ~453 mi on the same tank; M4 falls closer to 300 mi.

EPA-published annual fuel cost for the 2025 430i xDrive Coupe at 15,000 mi/yr, 55/45 city/highway split, using premium gasoline pricing. M440i climbs past $2,900 and M4 above $3,700.

Every 2025 4 Series Coupe variant — 430i, M440i, M4 — 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 2025 BMW 4 Series Coupe; estimate is derived from the shared CLAR platform with the 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 2024 or 2025 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 2025 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 the Mercedes CLE's more inclusive standard suite.

BMW's front collision prevention has earned Superior daytime and Advanced/Superior nighttime pedestrian ratings on the shared-platform 3 Series; the 2025 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 2025 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 current G22 cars.

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 85 mph on divided US highways with driver eye monitoring, offered on the 2025 4 Series via the Driving Assistance Professional Package. Mapped-road coverage is narrower than GM Super Cruise's ~750k-mile network but the system is mature and available.

The 2025 LCI brought new headlight styling but the base 4 Series retains standard LED headlights with automatic high beam; adaptive LED remains optional and trim-locked on upper trims. IIHS testing on the current 4 Series has generally shown Acceptable on volume-trim headlights, Good 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) 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 — carried forward through the 2025 LCI refresh; 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 wheelbase (112.2 in). Unchanged by the 2025 LCI refresh.

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 expands the load bay for skis/long items.

Typical BMW cabin storage: modest covered console with wireless charging tray, small door bins with bottle holders, front cupholders, and a 40/20/40 folding rear seat with ski passthrough. Competent but no standout tricks like frunks or hidden bins.

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 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, heated front seats, and wireless charging on all trims; heated steering wheel bundled in the Premium Package, and ventilated front seats plus heated rear seats available on M440i and up. Well-equipped but a step behind rivals that make heated wheels standard.

Base trim is the 430i Coupe (RWD) with the B48 2.0T turbo-4. The 2025 model year received the G22 LCI mid-cycle refresh (revised front/rear styling, standard Curved Display with iDrive 8.5), with a modest price uplift over the 2024 base of $49,995 + $995 destination. BMW's 2025 destination charge rose to $1,175.

The volume build is the 430i xDrive (~$53,170 with destination) fitted with the Premium Package (heated seats, keyless entry, moonroof, wireless CarPlay/Android Auto) plus M Sport wheels or the Convenience Package — the two most-selected option groups per BMW configurator data.

BMW dealer labor rates, premium parts (run-flat tires, iridium plugs, adaptive dampers where fitted) and turbocharged inline-6/turbo-4 servicing push 5-year maintenance and out-of-warranty repair to the top of the coupe segment band. The 3-yr/36k Ultimate Care mitigates early scheduled maintenance but years 4-5 (brakes, tires, potential VANOS/thermostat/gasket labor) carry the total higher than a 2 Series.

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. 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.

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 segment leaders (Hyundai/Kia/Genesis 10-yr/100k) and shorter than Mercedes' overlap coverage.

BMW Ultimate Care includes 3-yr/36,000-mi factory-scheduled maintenance (oil, filters, brake fluid, inspections) — one of the better complimentary programs in luxury (Audi and Mercedes-Benz provide little to nothing at that duration). Paired with 4-yr/unlimited-mile roadside assistance and BMW ConnectedDrive/eCall trials. No included charging/fuel credits (gas-only).

$58,200 volume-trim price minus its estimated resale value after 5 years (46% retained, or about $26,772) leaves about $31,428 in depreciation. Add the projected $9,200 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $40,628 in total.

G22 4 Series has tracked around average predicted reliability in Consumer Reports through the current generation, and J.D. Power quality scores for the model land in the low-80s. 2025 introduces the LCI refresh with iDrive 8.5 and updated infotainment/headlights, adding a modest early-life electronics risk on top of the otherwise settled B48/B58 + ZF 8HP hardware shared with the 3/2 Series.

BMW consistently sits in the upper-middle of dependability rankings — solid but not top-tier. J.D. Power 2024 VDS places BMW slightly above industry average behind Lexus/Genesis/Toyota, and Consumer Reports 2024 brand reliability ranks BMW around 10th of 34 brands. Best of the German premium set alongside Porsche but well behind the Japanese leaders.

The G22 4 Series has accumulated typical recall activity through its run — backup camera image display, seatbelt anchor, occupant classification, 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 2025 LCI cabin uses SensaTec/leatherette or optional Vernasca leather, aluminum or wood trims, and BMW's curved 12.3-inch/14.9-inch display; reviewers rate materials as competitive-to-strong for the mid-$50K luxury coupe class though below the plusher Mercedes CLE Coupe on perceived richness in some low-touch zones.

Assembly at BMW's Munich plant produces tight, consistent panel gaps and solid door thunk with low rattle rates in early ownership; iDrive 8.5 has drawn scattered UI/software complaints but no widespread build issues. 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.

2025 marks the first model year of the G22 LCI refresh, which introduced BMW's Curved Display: a 12.3" driver instrument panel merged with a 14.9" central touchscreen behind a single glass, standard on the 430i volume trim. Among the largest displays in the luxury coupe class.

iDrive 8.5 on the new Curved Display is fast and graphically rich; the 4 Series remains one of the last BMWs to keep the physical iDrive rotary controller alongside touch input, which reviewers cite as a big usability win. Climate controls migrated into the touchscreen, which draws some criticism.

Wireless Apple CarPlay and wireless Android Auto are standard on every 2025 4 Series Coupe trim (430i, 430i xDrive, M440i xDrive) 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 and reviewers consider it worth using over phone projection.

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

12.3" fully digital cluster within the new Curved Display is standard on all 2025 trims. Crisp, offers multiple driving-mode layouts and integrated map view; slightly less customizable than Audi Virtual Cockpit but larger and better integrated visually.

BMW Remote Software Upgrade delivers periodic OTA updates covering iDrive, maps, and select vehicle functions. 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 and Android devices. Core ConnectedDrive functions free for the first several years.

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 and available on 430i via option group. BMW Digital Key Plus (UWB, unlocks without waking the phone) 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.

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. Broadly attainable rather than volume-trim standard.

Two-door coupe with LATCH anchors at the outboard rear positions, but loading kids and 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 (forward-collision warning with city AEB, blind-spot detection, lane-departure warning, active cruise) is standard across the 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 rating for it.

Trunk holds 12.0 cu ft and rear legroom is marginally better than the 2 Series, 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.

Refined 2.0L turbo-four with 48V mild-hybrid assist, ZF 8-speed, standard Active Driving Assistant, well-bolstered sport seats and BMW's iDrive 8 curved-display cockpit combine into a low-fatigue daily. Firm ride on run-flats and low seating position are minor drawbacks.

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.

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 reversing camera and available Parking Assistant Plus with 360° cameras 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 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 still 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 ski 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 composed body control, strong grip and near-50/50 weight distribution; standard RWD (or optional xDrive) plus taut adaptive M-tuned damping make it one of the better-handling luxury coupes. Larger and heavier than the 2 Series so slightly less darty, but more planted at speed.

Quick, accurate rack with well-judged weight and consistent effort build-up, but BMW's variable-ratio EPS is criticized by reviewers for muted on-center feedback compared with older hydraulic BMW systems. Precise enough for confident placement without being especially communicative.

Firm, linear pedal with strong bite and good fade resistance; instrumented 70-mph stops for the M440i xDrive land in the 155-160 ft range on all-seasons, better on summer rubber. Optional M Sport brakes further boost repeatable performance.

BMW's B48 turbo-four (430i, 255 hp) and B58 turbo-six (M440i, 382 hp) — both paired with 48V mild-hybrid assistance and the ZF 8HP automatic — are benchmarks for drivability: prompt tip-in, minimal turbo lag, and near-imperceptible shifts. MHEV integration smooths stop/start and low-speed torque delivery.

The M440i's B58 inline-six has a rich, cultured tone under load and the 430i's B48 four is well-isolated for its class. Some cabin sound is synthesized in Sport modes, but background NVH is low and cruising is quiet.

BMW USA specification sheet for the G22 4 Series Coupe 430i RWD lists curb-to-curb turning diameter near 39.4 ft; xDrive variants add a small amount to that figure. Long wheelbase for the class limits maneuverability in tight spaces.

Low, sporty seating position with wide seat/wheel adjustment range and supportive standard sport seats; controls are logically placed and an optional head-up display keeps eyes on the road. Rear over-shoulder visibility is compromised by the coupe roofline and thick C-pillars, and the LCI-updated curved-display iDrive 8.5 layout puts more HVAC/audio functions on the touchscreen than on physical controls.

Rear-drive-biased chassis, willing balance and a charismatic B58 inline-six in M440i form make the 4 Series an engaging drive; even the 430i feels lively thanks to the quick-shifting ZF 8HP. Slightly bigger and less playful than the 2 Series but a more mature grand-tourer feel.

2025 is the first year of the G22 LCI refresh: 430i standard content adds the new Curved Display (12.3" cluster + 14.9" touchscreen) with iDrive 8.5, standard wireless Apple CarPlay/Android Auto, LED headlights, SensaTec 8-way power sport seats, dual-zone climate, and the Active Driving Assistant ADAS bundle. Solid at ~$51k, but heated front seats, moonroof, keyless entry, and Harman Kardon audio still live in the Premium and Convenience packages — competitive rather than generous versus a well-optioned Lexus RC or the fresh Mercedes CLE.

The M440i xDrive delivers 382 hp from the B58 3.0 turbo I6 with 48V mild-hybrid, AWD, adaptive M suspension and M Sport differential for ~$61k — one of the best performance-per-dollar plays in the luxury coupe segment against the Mercedes CLE 450 (~$65k) and Lexus RC 350 F Sport. The 430i at ~$51k trades some content for signature BMW chassis balance and the new curved display; bang-for-buck edges the fresh CLE but remains behind the smaller M240i.

2025 lineup covers 430i (RWD), 430i xDrive, and M440i xDrive on the coupe body, with the separate M4 / M4 Competition / M4 CS as the halo, plus 4 Series Gran Coupe and Convertible siblings widening the family. No manual gearbox on the volume trims and the M440i is xDrive-only in the US — reasonable breadth for a luxury coupe but narrower than the 3 Series sedan ladder.

The 4 Series remains the best-selling two-door in BMW USA's lineup and one of the top-selling luxury coupes in the country, outselling the 2 Series and 8 Series and gaining share as Audi has withdrawn the A5 Coupe from the US market. Overall coupe segment volume continues to shrink as buyers migrate to SUVs, so absolute numbers are modest — steady mid-to-upper-pack seller in a contracting class.

BMW consistently ranks among the top-tier luxury brands with strong enthusiast credibility via the M sub-brand, and the 4 Series inherits the M4 halo directly. The polarizing large vertical kidney grille introduced with the G22 generation carries into the LCI and remains the most-cited critique of the model's image; still, brand pull on the 4 Series badge is well above the segment median.

BMW Financial Services runs subsidized lease and low-APR programs on the 430i and M440i most months, and loyalty/college-grad/Corporate Fleet Program cash typically stacks — but as the first year of the LCI refresh, MY2025 4 Series inventory transacts closer to MSRP than the late-cycle pre-refresh cars, with typical dealer discount only low-single-digit percent. Better buyer economics than a Porsche or a fresh Mercedes CLE, but nowhere near mainstream-rebate territory.

MY2025 is the LCI mid-cycle refresh year for the G22 generation (launched MY2021): updated front/rear styling, the standard Curved Display, iDrive 8.5, revised trim colors, and 48V mild-hybrid across the range. The freshest the current 4 Series will be — buyers face no imminent redesign risk and get the newest cabin tech in the lineup.

Reviews of the refreshed 2025 4 Series praise the M440i xDrive's chassis, steering, and B58 straight-six drivetrain, and credit the LCI's Curved Display and iDrive 8.5 as meaningful cabin improvements; the 430i earns praise for balance if not thrills. Grille styling and the fresh CLE keep it out of Car and Driver 10Best for the non-M car, but frequent Editor's Choice mentions and strong U.S. News/Edmunds rankings place it in the upper tier of luxury coupes.
