Only few cars arouse the enthusiasm of enthusiasts like the BMW 5. After a long elaboration, the latest super saloon from the Munich brand has arrived. The new M5 is not only the most powerful car to have adopted the iconic badge. It is also the heaviest M5 of all time because it is combined with the plug-in hybrid mode. As expected, under the bonnet is the XM's DNA, namely the 585bhp twin-turbocharged 4.4-litre V8 to which is added a single 197bhp electric motor fed into the 8-speed transmission. Total system output is 727 hp and up to 1,000 Nm of torque, the electric motor is the same as the XM's while the battery is smaller than the XM's, namely 14.8 kWh.
The new M5 accelerates from 0 to 100 km/h in 3.5 seconds. The top speed is limited to 250 km/h, although it goes up to 305 km/h with the M Driver package. The flip side of this speed is the silent, purely electric operation provided by a plug-in hybrid. In electric mode, in fact, the new M5 provides up to 67 or 69 km of silent range on battery power alone. However, if you step on the accelerator or decide to change the M Steptronic transmission, the new M5 will turn on the engine for more power.
Speaking of driving dynamics, there are three standard driving modes for the new M5. Sport and Sport Plus liven things up by keeping the engine revved up, but the optional Dynamic and Dynamic Plus settings are essential for the most complete M5 experience. These modes optimise the powertrain for maximum power and increase cooling on the track. Dynamic is also how you switch from the xDrive all-wheel drive system to rear-wheel drive. This can be achieved by deactivating the stability control, for an unprecedented experience.
There is an electronically controlled differential lock for the rear that can send power to the left or right as needed to get the job done, functioning not unlike a stability control system. The difference here is that power, not brakes, is used to keep the M5 on the road. This results in faster and safer cornering, further aided by active rear steering that turns up to 1.5 degrees.
Stopping the new M5 are six-piston calipers on 16.1-inch discs at the front, with single-piston floating calipers biting 15.7-inch discs at the rear. Carbon ceramic M brakes are optional, increasing the front disc size to 16.5 inches. Behind a set of staggered wheels measuring 20 inches in front and 21 in the rear. This is all part of the M5's bespoke drivetrain configuration, which goes far beyond the stiffer springs of the 5 Series. The five-link rear axle is model-specific and uses reinforced control arms, camber control arms and steering arms designed for higher g-loads.
