G80 BMW M3 and G82 BMW M4 – Two Street Legal Beasts!

Regarding these two cars, the BMW M3 and BMW M4 are outstanding performers; they are in the same class or category and share most features, although the latter can be driven on a street. I love these cars because they are very slick and have a very aggressive look.

Listed in this case are G80 BMW M3 and G82 BMW M4.

After the market introduction of both BMW M3 Sedan and BMW M4 Coupé just some months ago BMW M GmbH extends the model range by two further versions and thus brings the M xDrive all-wheel drive for sports cars in the premium mid-class segment on the market.

The precise protagonist of output for the engine provides counted power delivery to all wheels which in turn enhances the dynamism of BMW M3 Competition Sedan with M xDrive and BMW M4 Competition Coupé with M xDrive.

Both the BMW M3 Competition model and the BMW M4 Competition models also have the same inline six-cylinder M TwinPower Turbo drive unit.

This means a combination of two mini scroll compressors, direct injection (with a maximum pressure of 350 bar), valve opening variation, and double-VANOS timing control. Total power is 375 kW/510 hp at 6250 RPM, while maximum torque is 650 Nm available between 2200 and 5500 RPM.

The all-wheel-drive system specially developed for the BMW M intelligently and continuously distributes power between the front and rear wheels as required to continuously enhance agility, directional stability, traction, and power for track-oriented dynamic performance.

The oil supply to the multi-disc clutch has been optimized to maintain the efficient operation of the variable power distribution mechanism even under extreme track conditions.

The task of transmitting power to the front and rear differentials are handled by driveshafts designed specifically for the BMW M3 Competition Sedan with M xDrive and BMW M4 Competition Coupé with M xDrive. And the output shafts that relay torque to the wheels are specially developed components.

We are talking about G80 BMW M3 and G82 BMW M4.

The AWD architecture in this model is a Torsen limited-slip differential, where the primary role is to manage the torque to the rear end. Usually, all the power is transmitted to the rear wheels and the front wheels only get power when the rear wheels cannot transfer all the power to the ground.

To achieve this, the extensive bespoke changes to the all-wheel-drive system mean that the rear-wheel drive models as well as the new M xDrive models have the M-specific steering developed uncompromisingly.

With the new additions of two all-wheel-drive model variants to the mid-size class, BMW M GmbH now has the most diverse all-wheel-drive high-performance options.

Between the two: the BMW M3 Sedan and the BMW M4 Coupé depicts different strategies in handling competition through rear-wheel drive and six-speed manual transmission. As in BMW M3 Competition Sedan and BMW M4 Competition Coupé, power is also distributed to the rear axle although through the newly introduced eight-speed M Steptronic transmission with Drivelogic. This powertrain can be ordered with the M4 Competition Coupé through the replacement of an eight-speed M Steptronic transmission with Drivelogic.
