The BMW F82 , sales designation M4 is one since 2014 offered sports coupe and the highly motorized version of the 4-series of BMW . The cabriolet itself has the factory designation F83 . A motorsport variant is offered with the BMW M4 GT4 .

Model history

After the coupé was presented on the Internet at the end of 2013, an official presentation at the North American International Auto Show (NAIAS) 2014, the M4 initially started as a coupé in spring 2014; the Cabriolet, which was officially presented at the New York International Auto Show (NYIAS) in early 2014 , was launched in the fall. They replaced the coupé and cabriolet of the BMW M3 . The four-door sedan, which has the same engine and is technically largely identical to the M4, will continue to be marketed as the M3 (F80) .

technology

engine

As with the sedan, the engine is a twin-turbo in- line six-cylinder engine with 2979 cm³ displacement with charge air cooling . He is the BMW N55 derived, has a maximum power of 317 kW (431 hp) and a maximum torque of 550 Nm from 1,850 to 5,500 min -1 .

The new turbo engine consumes less fuel than the high-revving V8 engine of the predecessor. At 8.8 and 8.3 liters per 100 kilometers, it has a 25 percent lower fuel consumption than the fourth-generation M3 and meets the EU6 emissions standard. Dry sump lubrication ensures the oil flow so that the engine is always well lubricated even when driving with high lateral acceleration forces. The M4's oil pan is made of magnesium . The motor allows speeds of up to 7500 min −1 ..

drive

There is a choice of a six-speed manual transmission, which, including the two-disc clutch, weighs 12 kilograms less than its predecessor, and a 7-speed dual clutch transmission , the latter causing faster acceleration despite 25 kilograms more weight.

The "M double clutch transmission" is a 7-speed double clutch transmission with so-called "Drivelogic", which, according to BMW, is specially designed for the "M high-speed engines". The system has traction-optimized automatic gear selection, Launch Control , "Low Speed ​​Assistance" and an "Auto Start Stop" function. Two sub-transmissions (one for gears R / 2/4/6, one for gears 1/3/5/7), each with their own clutch, transmit the engine power to the rear wheels. It is controlled automatically or manually using shift paddles on the steering wheel or the shift lever. The “Launch Control” function enables a start from a standing start with maximum acceleration. The Drivelogic provides three shift programs to choose from in both automated (D mode) and manual (S mode) - from sporty to comfortable or consumption-optimized.

The newly developed “Active M Differential” optimizes traction and driving stability when changing lanes and accelerating out of bends, at high cornering speeds and on different road conditions. The road grip is optimized using an electronically controlled lamella lock to reduce the speed differences between the rear wheels. The rear-axle locking differential locks variably from 0 to 100 percent.

body

Lightweight construction measures were used in the development of the M4. The bonnet with the characteristic “power dome” and the fenders are made of aluminum. The roof is made of carbon fiber reinforced plastic (CFRP) , which saves 6 kg in weight. The tailgate and strut bar are also made of CFRP. The strut bar weighs only 1.5 kg, but offers a stiffness that would not be achieved with aluminum. With these measures, the curb weight could be reduced by 83 kg compared to its predecessor, but it is still more than 1.5 tons.

In addition to weight, aerodynamics also play a role in a sports car . The "M-gills" behind the front wheels reduce the turbulence on the front wheel arches. The underbody is smoothly covered. The c w value is 0.34 (frontal area 2.23 m²).

landing gear

The electronically controlled shock absorbers of the "Adaptive M Chassis" constantly adapt to the road conditions and driving style within milliseconds and are intended to ensure optimal, situation-dependent contact with the road, optimized traction and even more agile handling. The chassis configuration can be configured from comfortable to sporty-dynamic via the settings “Comfort”, “Sport” and “Sport +”. The "Comfort" mode should be suitable for comfortable locomotion during everyday journeys. In "Sport" mode, if there is sufficient comfort, the wheel movements are reduced and road contact is more direct; this mode is said to be ideal for country roads and undulating racetracks. Minimum wheel movements and maximum driving dynamics on level roads and racetracks should be achieved with the "Sport +" setting.

The cardan shaft is also made of CFRP; numerous chassis components made of forged aluminum.

Furnishing

The M4 is supplied with LED headlights and LED taillights as standard.

The characteristics of the accelerator pedal, steering, damping and shifting can be adjusted in three different electronic settings. There are two programmable M buttons on the steering wheel within easy reach of the left thumb - the preferred setup for different situations can be activated at the touch of a button.

variants

M4 DTM Champion Edition

The BMW M4 was first launched in 2014 as a DTM Champion Edition, based on Marco Wittmann's victory in the 2014 DTM season . The color of the model is based on Wittmann's M4 DTM of the 2014 season. The 2014 Champion Edition is limited to 23 copies, Wittmann's start number.

After winning the 2016 season , BMW again released a DTM Champion Edition of the M4. The M4 DTM Champion Edition relies on the engine known from the M4 GTS with 368 kW (500 PS) maximum power and water injection . All performance data are identical to those of the GTS. The model is limited to 200 pieces and is based on the DTM vehicles with the basic color white. The biggest visual difference to the GTS lies in the smaller spoiler and the absence of the orange design elements. The price is 148  € 500 slightly above that of the sold out GTS.

M4 GTS

At the Tokyo Motor Show in October 2015, BMW presented the special model M4 GTS based on the coupé . This is limited to 700 copies and was sold out in November 2015. The engine comes from the M4, but in the special model it delivers a maximum of 368 kW (500 hp) through water injection. Another world first in a series vehicle were the OLED rear lights. The weight of the model was reduced by using more carbon, etc. a. for the bonnet, and a titanium exhaust further reduced. A carbon ceramic brake is part of the standard equipment. The first vehicles were delivered at the end of April 2016 at prices of 142 600  €.

M4 CS

At Auto Shanghai in April 2017, BMW presented the M4 CS based on the coupe . This essentially differs from the production model in that its output has increased by 21 kW (29 hp), the curb weight has been reduced by 35 kg and the chassis is sportier. Externally it can be recognized by a modified front spoiler and at the rear by a spoiler lip and OLED taillights. Just like the GTS, it has a carbon-ceramic brake system.

At least 116 will be built 900  € expensive vehicle since July 2017 in Munich. The M4 CS is only limited by the production period from 2017 to 2019.

Motorsport

A motorsport version of the M4 F82 that is approved for the GT4 group has been available since mid-2017 . The first test race was carried out at the Dubai 24h 2017.
