Cabin appointments have moved more upmarket with similar appointments from its cooking siblings, but spruced up with M5-specific items, such as the form-hugging front chairs with their illuminated M5 logo, new digital dials and a new steering wheel.
The latter is home to the M buttons — M1 on the left and M2 on the right, finished in red. The start button, too, is now in a scarlet red hue, while the gear lever and centre console are model-specific items.
Under the bonnet lies a similar 4.4l twin-turbo V8 to its predecessor, but featuring new turbos and a higher flow fuel-injection system with a 350bar pressure (150bar more than the predecessor). This has resulted in 441kW at 5,600r/min, like the previous Metal Edition variant, but with 750Nm at 1,800r/min — 50Nm more.
Not that the model needed more power to begin with, but what it was begging for was better traction and the M xDrive four-wheel drive system in the new model has done just that.
It is a variable system that is mostly rear-wheel biased and gives the vehicle superior traction under most conditions. The model is said to accelerate to 100km/h in 3.4 seconds and go on to a top speed of 250km/h (305km/h should you specify the Driver’s Package option).
M Dynamic Mode neuters slightly the dynamic stability control, allowing some slip at the rear for a rear-biased four-wheel-drive feel. This was apparent while flinging the vehicle around the Estoril racetrack in Portugal. Be more aggressive with the throttle out of corners and the vehicle will go into a controllable four-wheel drift.
Select 2WD mode and it morphs into a rear-wheel-drive only machine that allows you gratuitous rear-tyre burnouts should you be so inclined.
The exhaust system has been fettled with a resonator that gives the engine clearer vocal chords for its V8 tune.
The new model comes with an eight-speed automatic gearbox instead of the seven-speed dual clutch variety. According to the engineers, this is to make it more driveable in peak traffic.
The new BMW M5 has ironed out all that was amiss with the previous model to arrive at what is the most useable and refined M5 yet.
