Driving the 4.4L Petrol AT
The F90 M5 carries over the 4.4L V8 from the F10. It gets some updates and a higher power output of 592 BHP @ 5,600 - 6,700 rpm. Interestingly, the F10 M5 made 592 BHP too, in the limited edition Jahre and Competition editions. The engine puts out 750 Nm of torque @ 1,800 - 5,600 rpm and powers all four wheels. Now, the all-wheel-drive system in this is a bit different from others. It, by default, sends all of its power to the rear wheels, and if needed, it transmits power to the front. The 0-100 timing has been recorded by various people at between 3.2 and 3.4 seconds, which frankly is ridiculous! Of course, its all due to the extra traction offered by the all-wheel-drive system.
Another big change, I would say, is the use of a conventional torque converter transmission. It is a ZF 8-speed called M Sport automatic transmission. The shift times are quicker than the standard 8-speed torque converter. Lock up happens very early, and it is also locked up most of the time so that the feel is more direct. The earlier M5 and M3 used dual-clutch transmissions, and the E60 M5 and the E46 M3 used single-clutch transmissions. While this transmission is brilliant in every way, the only time you would miss the DCT or SMG is during a gear change when going flat out. The automatic transmission just doesn’t have that ‘jhatka’ during the gear shift which really gives you a mechanical feel, in spite of the shift times now being faster than the DCTs.
Getting into the comfortable multifunction seats, the interior somehow feels familiar. The red M1 and M2 buttons stand out on the steering wheel. There is now a red engine start button too, and when you press that, the start-up sounds all too familiar! Flicking the gear shifter to the right into D, I let go off the brake and was surprised to feel the M5 move ahead. Even when the M division used the 8-speed in the X5M, the creep function was removed and you had to press the accelerator to move front, so it was quite a surprise to feel the creep in this. Moving on, driving in Mumbai city traffic, the M5 feels very comfortable and is not a struggle at all. The width is something to be watched out for, but apart from that, its easy to drive.
Driving sedately, the M5 feels completely at home. Its truly something which can be used every day. Turbo lag is non-existent, and seeing how it makes the 750 Nm of torque from 1,800 rpm onwards, this is not surprising. The gearshifts too are smooth and imperceptible, when the gearbox is left in one of the lower Drivelogic settings. But start hustling, and that’s when the M5 wakes up. If you have preset one of the M buttons like I did (everything in Sport Plus and traction in 4WD Sport), pressing it truly wakes the beast up. It feels like you are in a different vehicle. The way the F90 M5 accelerates needs to be felt to be believed. It pushes you back into the seat properly, and the push just gets harder all the way till the redline! The M5 seems to defy physics in the way it accelerates to jail-term speeds, and it is absolutely relentless.
What is truly special is the way the vehicle launches to a 100 km/h. With the earlier RWD sedans, the traction light would be blinking constantly till 100-120 km/h. With this, there is a blink or two in first gear and that’s it. Even on Mumbai’s dusty concrete roads, it just grips and goes! The all-wheel-drive system works seamlessly and you will never figure out when and how much torque is transferred to the front wheels. Its really tricked out. But at the same time, for M purists, having all-wheel-drive means a loss of one important thing – drama! Be it the E60 M5 or the F10 M5 or even the F80 M3, you know you’re in an M car when you’ve got to keep both your hands on the steering wheel when you accelerate hard, especially if the car is in MDM mode. With all-wheel-drive, the drama of having the tail lose and having to counter slightly with the steering wheel is gone. You can keep one hand on the steering and the M5 just goes! But at the same time, the kind of grip offered through corners is really, really good. You can start accelerating out of a corner with full throttle without a worry, whereas in a rear-wheel-drive car, the tail would surely kick out. So in terms of absolute speed, the all-wheel-drive system has given the F90 M5 a big boost.
In terms of ride quality, at low speeds, there is a bit of body movement. You feel every undulation on the road, but the suspension is well damped. It is never uncomfortable in spite of the 20” rims. As the speed picks up, the ride gets even better and it flattens small and medium bumps. On the highway, the ride is perfectly comfortable and I found nothing really lacking in terms of comfort. Of course, large bumps and potholes have to be watched out for, because of the low profile tyres. But on the whole, the M5 is very useable in the city and on the highways too.
Handling is great, and the grip levels are very high. It almost never seems to want to lose grip even when it is really pushed through the corners. I managed to get the tail out a bit in 4WD Sport only on two corners, and while it was predictable, I didn’t really enjoy it. 2WD mode was far better in that sense, but then again, you’ve got to really watch out since the traction control is turned off completely. The M5, on the whole, feels very agile and the steering is quick and communicative. It is also worth mentioning that the steering is fully electric, and I found it better in terms of feel than the F10 M5 steering, which was hydraulic. The chassis just feels really, really tight in spite of the size, and it feels a size smaller than it actually is when its being pushed.
So to conclude, the F90 M5 is supremely fast and practical, but misses out on a bit of the drama from the rear-wheel-drive M cars in everyday driving. But it makes driving fast very easy, and is certainly a great buy for those considering!
The menu where you set up the M1 and M2 buttons. For M2, everything is in the sportiest setting, but the suspension is in comfort for the terrible Mumbai roads:
This is where you select between 4WD and 4WD Sport (also puts the M5 in MDM), and 2WD, which switches the traction control off completely:
The red M1 and M2 buttons are right in your face, and I think this new placement of buttons is great:
