The BMW M4 is a high-performance version of the BMW 4 Series automobile developed by BMW's motorsport division, BMW M GmbH. Part of the renumbering that splits the 3 Series coupé and convertible models from the 4 Series (to further differentiate it from the 3 Series), the M4 replaced the M3 Coupé and Convertible models. Upgrades over the standard BMW 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 fibre, especially on the roof of the car.

|Predecessor||BMW E92/E93 M3|
On September 25, 2013, BMW released the technical specifications of the M4 powered by an M-tuned S55B30 engine. Although it is a 3.0-litre inline-6 engine, BMW states that it is completely different to the N55 engine used in the base 4 Series models and that the engine has been built specifically for the new M4/M3, having a redline of 7,800 rpm with the rev limiter coming in at 7,600 rpm. The engine uses two mono-scroll turbochargers with a peak boost pressure of 18.1 psi (1 bar). The power is rated at 317 kW (431 PS; 425 hp) while the torque is rated at 550 N⋅m (410 lb⋅ft). The weight of the M4 equipped with a manual transmission is 1,572 kg (3,466 lb) and with the M-DCT, the car is some 40 kg (88 lb) heavier, losing some 80 kg (176 lb) from the E92 M3. Two transmission choices are available, those being the 6-speed manual and 7-speed M-DCT transmissions. The 7-speed M-DCT transmission accelerates the car from 0 to 100 km/h (62 mph) in 4.1 seconds). With the 6-speed manual transmission, the car accelerates from 0 to 100 km/h (62 mph) in 4.3 seconds.
Carbon fibre reinforced plastic is used extensively throughout the car, including drive shaft, roof, roof bow, trunk, and front strut brace. For the first time in a M vehicle, an electric power steering unit is being used. The steering system is specifically tuned for both 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 inducted into the passenger cabin via speakers in the car. 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 in the system.
The convertible variant of the M4 was announced along with its coupe sibling. It shares almost everything with the coupé 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 (62 mph), 4.6s with the manual and 4.3s with the M-DCT transmission.
F82/F83 Competition Package
During February 2016, BMW announced the M3/M4 Competition Package. With this package, the M4 boasts 331 kW (450 PS; 444 hp) and a revised suspension for better handling. New springs, dampers and anti-roll bars complement the included Adaptive M Suspension. BMW also re-tuned 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 (62 mph) in 4.0s, while the convertible version does the run in 4.2s, both using the dual clutch transmission.
F82 M4 GTS
BMW introduced the M4 GTS concept in August 2015 at the Pebble Beach Concours d'Elegance. In 2016, BMW released 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 and a price tag of $133,205. 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 has been raised to 500 PS (370 kW; 490 hp) at 6,250 rpm and 600 N⋅m (443 lb⋅ft) of torque at 5,500 rpm largely due to a novel 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.
F82 M4 CS
In Spring 2017, BMW announced M4 CS in limited run of 3,000 units globally. The M4 CS sits between M4 Competition Package and M4 GTS. The M4 CS utilises the same engine as the standard M4 which generates 338 kW (460 PS; 453 hp) and 600 N⋅m (443 lb⋅ft) of torque.
The M4 GT4, aimed at amateur drivers, debuted at the 2017 24 Hours of Nürburgring. It features a 3.0L turbocharged straight-six engine producing 431 PS (425 hp; 317 kW), and a 7-speed dual clutch transmission.
