The BMW M4 is a high-performance version of the 4 Series automobile developed by BMW's in-house motorsport division, the BMW M GmbH. Part of the renumbering that BMW splits the 3 Series coupe and convertible models to the 4 Series (to further differentiate with the 3 Series sedans), the M4 replaces the M3 Coupe and Convertible models. Upgrades over the standard 4-Series include: a very powerful and responsive, twin turbocharged engine; improved handling, suspension, and braking systems; aerodynamic body enhancements; interior/exterior accents with the tri-colour "M" (Motorsport) badging; the significantly reduced weight compared to the standard 4 series and its predecessor with an all-new stiffer chassis and extensive use of carbon fiber, especially the roof of the car. The car will be starting at $65,700 MSRP.
F82/ F83 M4[]
BMW officially presented the M4 concept on August 16, 2013. However, the concept car did not reveal any interior or technical details.
On September 25, 2013, BMW released technical specifications of the M4 powered by a M-tuned S55B30 engine, although it is a 3.0 L inline engine. BMW states that it is completely different to the N55 engine seen in other BMW 35i models, this engine has been built specifically for the New M4/M3, displacing 3.0 L (180 cu in) and redlining at 7,500 rpm. The rev limiter coming in at 7,600rpm. The engine uses two mono-scroll turbochargers with boost peaking at 18.1 PSI. The power is rated at 425 hp (317 kW; 431 PS) while torque will be 550 N·m (410 lb·ft). The weight of the 6 speed manual M4 is 3,556 lb (1,613 kg), with the M-DCT some 88 lb (40 kg) heavier. Both 6-speed manual and 7-speed M-DCT transmissions are available. The 7-speed M-DCT transmission accelerates the car from 0 to 100 km/h (62 mph) in 4.1 seconds). The 6-speed manual transmission does 0 to 100 km/h (62 mph) in 4.3 seconds).
Carbon fiber reinforced plastic is used extensively throughout the car, including drive shaft, roof, roof bow, trunk, and front strut brace. For the first time in the M vehicle, an electric power steering unit is being used. The steering system is specifically tuned for the M3 and M4. The 18 inches (460 mm) and 19 inches (480 mm) wheel options are available with lightweight forged alloys being standard. The M compound brakes come standard (in blue), while carbon ceramic brakes (in gold) are available as an option.
The M4 features Active Sound. A live amplification of the engine's natural sound will be inducted into the passenger cabin via the speakers. BMW says this technology has been used so that the well insulated cabin can reduce road/wind noise but still provide the driver with the sporty sound of the M powered engine. There are no artificial sound or any pre-recorded track.
Overall, 50 percent of the components on the M4 are standalone compared to the F32 4 Series.
F83 M4[]
The convertible was announced along with its coupe sibling. It shares almost everything with the coupe version, but weighs more due to its retractable hardtop. The convertible weighs 1,750 kilograms (3,858 lb) (manual), 60 kilograms (132 lb) less than its predecessor. The three-piece retractable hardtop folds in 20 seconds.
Because of its extra weight it accelerates slower, taking it 0.3s longer to 100 km/h, 4.6s with the manual and 4.3s with the D-CT transmission.
Competition Package[]
During February 2016, BMW announced the M3/M4 Competition Package. With this package, the M4 boasts 444 horsepower and a revised suspension for better handling. New springs, dampers and anti-roll bars complement the included Adaptive M Suspension. BMW also retuned the electronic differential and the Dynamic Stability Control to match the upgraded hardware. The interior remains largely unchanged, but Competition Package cars get new lightweight sport seats along with the M-striped woven seat belts. The exterior include the M Sport exhaust with black chrome tailpipes and high gloss Shadow Line exterior trim. Gloss black trim are added to the kidney grille, side gills, and model badge on the trunk.
With the competition package the Coupe version goes from standstill to 100 km/h in 4.0s, while the convertible version does the run in 4.3s, both using the dual clutch transmission.
The Competition package costs $5,000 for the M3/M4 coupe and $5,500 for the M4 Convertible on top of its base price.
M4 GTS (2016)[]
BMW introduced the M4 GTS concept in August 2015 at the Pebble Beach Concours d'Elegance. In 2016, BMW introduced the production version of the car which was a track-focused version of the standard M4 coupé itself with a limited production run of 700 units. It is powered by the same 2,979 cc (3.0 L; 181.8 cu in) twin-turbocharged straight-six engine as in the normal M4, but the power output has been raised to 368 kW (500 PS; 493 hp) at 6,250 rpm and 600 N⋅m (443 lb⋅ft) of torque at 5,500 rpm largely due to a nozzle water injection system that is the first to be used on a production automobile in almost twenty years. In addition to the increased engine power, the M4 GTS is 27 kg (60 lb) lighter than the standard M4 Coupé with the DCT transmission, so the weight now stands at 1,585 kg (3,494 lb). The 0 to 100 km/h (62 mph) acceleration time is reduced to 3.8 seconds, while the top speed stands at 305 km/h (190 mph). The M4 GTS has, according to BMW, lapped the infamous Nürburgring Nordschleife track in 7 minutes and 28 seconds, 24 seconds faster than the base M4 and 20 seconds faster than the M3 GTS. This equates to the same time as a Porsche Carrera GT.
M4 CS (2018-2020)[]
The M4 CS is a more track-focused version of the F82 M4. It had a limited run of only 3,000 units.
Second generation (G82; 2021)[]
The second iteration of the BMW M4 (codenamed G82) is a largely based on the standard 4 Series (G22 generation), which was previewed by the BMW Concept 4. It is a high performance version of the standard G22 4 Series. Prototypes of the BMW M4 have been seen tested on the Nurburgring beside the G80 BMW M3. The first units were assembled in November 2020, with global deliveries starting in early 2021.
The more notable upgrades for the G82 M4 is a 35 kW (48 PS; 47 hp) increase over the previous M4, as well as adopting the twin-kidney grille from the 4 Series.
The convertible version of the new M4 was introduced in May 2021. Like the standard new-generation BMW 4 Series Convertible, the M4 Convertible (internal designation G83) has a folding soft top. It normally opens/closes in 18 seconds, at speeds up to 50 km/h (31 mph). The convertible is available as a Competition model with the M xDrive. Top speed is electronically limited to 250 km/h (155 mph), but with the optional M Driver's Package, it can increase to 280 km/h (174 mph). As for acceleration on 0–100 km/h (0–62 mph), it is 3.7 seconds.
For the North American market, only the manual will be available in the standard M4.
For the Thailand market, the manual will be available in the standard M4 and automatic will be available in the M4 Competition they will be imported from Germany.

BMW M4 DTM[]
Main article: BMW M4 DTM
The BMW M4 DTM competed in the Deutsche Tourenwagen Masters from 2014 to 2020. Marco Wittmann won the 2014 and 2016 championships.
BMW M4 GT4[]
The BMW M4 GT4 is a competition version of the road car, sharing the 3.0 L turbocharged straight-six engine and 7-speed dual clutch transmission. Reuse of these elements of the road car, and of shared electronics systems including the TCS, are aimed at cost, maintenance, and driveability, with further race engineering reused from the GT3 version. Chassis are homologated under the SRO GT4 category, aimed at amateur drivers, with the engine trimmed to 317 kW (431 PS; 425 hp) in line with the Balance of Performance regulations. The car debuted at the 2017 24 Hours of Nürburgring.
BMW M4 GT3[]
The BMW M4 GT3 is a racecar version of the G82 BMW M4, homologated under the FIA Group GT3 category, which also enables entry to SRO, IMSA and ADAC competition. It is a direct successor[weasel words] to the BMW M6 GT3, racing from the 2022 season. The M4 GT3 will use a race-prepped variant of the inline-six from the road car. BMW M Motorsport stretches the front to add much wider fenders, and more angular styling for the hood accentuates the inward slanted brows above the headlights. The exhaust exits just ahead of the passenger side front wheel, on the right side of the car. At the back, there are inlets on the sides of the wider fenders. A gooseneck-mounted spoiler and rear diffuser manage the airflow. The steering wheel can be used in racing simulators without modifications. Deliveries started in late 2021.
