What it’s like to drive, and how quiet it is

One thing you quickly learn about the M5 is that it is so configurable, with settings for everything, that you can’t learn it quickly. However, as a general rule, if you keep the standard adaptive dampers in their softest setting and select Efficient mode via the Drive Performance button - for tamer accelerator response and less aggressive gearchanges, etc - the M5 bumbles around in a more relaxed fashion than the always more aggressive-feeling Mercedes-AMG E63.

Its turbocharged V8 remains hushed and biddable, and the eight-speed automatic gearbox shuffles neatly through its gears. Although there is some pitter-patter from the suspension over really battered town roads, considering the enormity of those tyres at each corner (demanded by the spectacular muscle this car has), it’s barely much of a compromise over a standard 5 Series. So, it’s comfortable and easy to drive when you want it to be: tick.

Switch to the other extreme, however, by ramping up the drive system to its most extreme Sport+ mode and the M5 demonstrates the distinctive duality that buyers of previous M5s have grown to love. Okay, even in its most aggressive mode the gearbox doesn’t have the instantaneous responses of the Porsche Panamera Turbo’s ’box, but for a turbocharged engine the accelerator response is virtually instantaneous – and then comes the power. And what power: it fires you up the road like the angry hand of God has just given you an almighty smack on the bottom. It gets a big tick for that.

And, despite weighing close to two tonnes, BMW has done an impressive job of concealing all that mass. The M5 determinedly resists lean through faster corners and stays superbly composed over even quite challengingly uneven roads. That’s one more tick, then.

Then there’s the four-wheel drive system. Thanks to this, you can deploy all 591 horses at any speed and in any gear with virtually no drama – beyond that of the rapidly rising speedometer on your licence – because traction out of corners in stupefying. In fact, it feels more like a grand tourer than a performance saloon in the way it effortlessly dispatches many miles in the blink of an eye on any road. In a word, it’s rapid – so that is another tick.

Yet it does all feel rather too easy; a bit too digital. Even the V8 engine sound is partly synthesised noise pumped through the speakers, so from a purist’s point of view is it a damp squib compared with the bonkers and shouty E63?

Well, no. If you switch the stability control to its midway point (called MDM mode), the rear-biased four-wheel drive system really lets you have some fun; get it on track and it will slip into tail-out oversteer like the great M5s of old.

Still think that’s not exciting enough? Then you can always take the nuclear option because, like the E63, you can switch off four-wheel drive to make the M5 rear drive only. Mind you, because this also completely disables the traction and stability controls to leave your skills ruthlessly exposed, this option is certainly best left for a closed circuit.

There are a few of criticisms. The steering is generally sweet and predictable, so you can easily place what at times – down a winding country road, at least – feels like a big beast of a car. But even in its least weighty mode, it wants to straighten up the wheel for you out of corners a tad too aggressively. There’s also very little sensation of the road beneath through the absurdly fat steering wheel.

Then there are the optional carbon ceramic brakes we tried. These are magnificently effective at stopping you from high speeds, but in town, when all you wanted was to roll up gently behind the car in front, they’re way too aggressive. The result is your passenger thinks you are a blithering idiot who can’t drive for toffee.

But the most infuriating thing about the M5 is the endless modes and settings you have to fiddle with. Surely, if a proper sports car such as a Porsche 911 doesn’t require you to pull over for five minutes to set the car up for a mile or so of twisty road, then stop again for another five minutes to change everything back before joining a motorway, does the M5? We doubt it.

Still, beyond all the gimmicks, this is still an almightily impressive saloon. In a straight line, it’s capable of eating supercars for breakfast while delivering you to your workplace unflustered – certainly less flustered than the more aggressive but arguably more exciting E63.
