The fifth edition of the BMW M3 with the internal code F80 has been available since spring 2014. In contrast to the previous models, only the four-door sedan is marketed as the M3 . The technically largely identical coupés and convertibles are now called M4 (Coupé: F82; Cabrio: F83) and thus belong to the BMW 4 Series.

Model history

After the model was presented on the Internet at the end of 2013, the official trade fair premiere was at NAIAS 2014. In mid-2015, the M3 received a facelift with slight visual changes to the rear. At the beginning of 2017 there was another facelift in which the front was changed. The M3 CS was unveiled at the end of 2017 and officially presented at the 2017 LA Auto Show . The CS is limited to 1,200 copies.

In February 2018, BMW announced that the M3 F80 would no longer be sold in Europe from August 2018. The reason for this is that the vehicle's engine cannot comply with the guidelines of the Euro 6d standard, which will become mandatory on September 1, 2018, without a petrol particle filter (OPF) . The M4, on the other hand, has a particle filter and will therefore also be produced for Europe beyond 2018.

technology

The M3 (F80), which is based on the BMW F30, is powered by a twin- turbo in-line six-cylinder with 3.0 liter displacement with a charge air cooler . The engine is of the BMW N55 derived provides 317 kW (431 hp) and 1850 to 5500 min -1 a maximum torque of 550 Nm. Acceleration from 0 to 100 km / h is 4.1 to 4.3 s, depending on the transmission. There is a choice of a manually shiftable six-speed transmission and a 7-speed dual clutch transmission ; the latter causes faster acceleration despite 40 kilograms more weight.

The new turbo engine consumes less fuel than the high-speed engine of the predecessor. With 8.8 or 8.3 l per 100 km, it has a 25% 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 well lubricated even under high acceleration . The M3's oil pan is made of magnesium . The motor allows speeds up to 7500 min -1 .

The F80 series is manufactured exclusively in the Regensburg plant .

When developing the M3 (F80), one of the conditions was the lightest possible construction. For the first time, the sedan has a roof made of carbon fiber-reinforced plastic , as was reserved exclusively for the coupé in its predecessor; this saves 5 kg of weight. The six-speed manual transmission including two-disc clutch weighs 12 kilograms less than that of the predecessor. The bonnet with the characteristic “power dome” and the fenders are made of aluminum. The strut bar made of carbon fiber reinforced plastic weighs only 1.5 kilograms and is stiffer than an aluminum part of the same weight would be. The cardan shaft is also made of CFRP; numerous chassis components made of forged aluminum. This enabled the curb weight to be reduced by 60 kg compared to its predecessor.

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 clad and the so-called " Gurney Flap " on the trunk of the sedan ensures higher contact pressure on the rear axle with reduced air resistance . The c w value is 0.34 (frontal area 2.29 m²).

The newly developed rear-axle locking differential ("Active M Differential") improves traction and driving stability when changing lanes and accelerating out of bends, at high cornering speeds and on different road conditions. An electronically controlled multi-plate clutch is used for this purpose, which reduces the speed difference between the rear wheels. The blocking effect is variable from zero to 100 percent.

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.

The electronically controlled shock absorbers of the “Adaptive M Chassis” permanently adapt to the road conditions and driving style within milliseconds and are intended to ensure optimum, situation-dependent road contact, higher 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 ensures comfortable locomotion during everyday trips and also ensures safety in the event of sudden evasive maneuvers. 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 are achieved with the “Sport +” setting.

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 automatic gear selection, traction control for the starting process ( Launch Control ), "Low Speed ​​Assistance" and a stop-start system . It enables very quick gear changes without interrupting the tractive effort. Two sub-transmissions, each with their own clutch, transmit the engine power to the rear wheels without interrupting the shift. Shifting takes place automatically or triggered by the driver using shift paddles on the steering wheel or the shift lever. As with the "Launch Control", which allows a standstill with maximum acceleration, this means: Shifting at full throttle, without a clutch pedal, with continuous power transmission. The Drivelogic provides three shift programs to choose from in both automated (D mode) and manual (S mode) - from extremely sporty to comfortable or fuel-efficient.

The M3 comes with LED headlights and LED taillights as standard.
