BMW M6 Coupe (2012) CAR review

By Georg Kacher

First Drives

14 November 2012 12:15

BMW has downsized the new M6 – but the good news is that less means more. As with last year’s M5 super-saloon, the charismatic F1-derived 5.0-litre V10 has been replaced with a more mainstream 4.4-litre twin-turbo V8. In the process, though, fuel economy has been improved by 30 percent, and power increased by 10 percent to 552bhp. The new V8’s torque curve is also absolutely flat all the way from 1500 to 5750rpm, dishing up a muscular 502lb ft in the process – 118lb ft more than before.

Is the new BMW M6 as complicated as the old car?

Unlike the previous model, you don’t need a button to access full power either – it’s on tap at all times. The new M6 doesn’t even need launch control to dispatch the 0-62mph sprint in 4.2sec, eclipsing its predecessor by 0.4sec. Not bad, considering its 1850kg heft means it’s gained 140kg on the model it replaces. Maximum speed is restricted to 156mph, but extra money buys an M Driver’s Package, with professional tuition, plus an ECU tweak that lifts the top speed to 191mph. Unless you live in the UK, because that’s not an option for British buyers.

The downsized V8 engine may be less exotic, less extreme and ultimately less involving than the V10, but the direct-injection and twin-turbo unit comes with all the bits that made BMW powerplants famous, including the Valvetronic lift system and double VANOS cam adjusters. It’s difficult not to like, with a soundtrack that ranges from a Wagnerian idle speed to a full-bodied multi-phonic aural climax inspired by Bruckner and Glass. It’s also almost impossible not be knocked out by the torque – it’s like a Muhammad Ali right hook.
Attached to this all-aluminium engine is the M version of the familiar seven-speed dual-clutch transmission that offers a choice of automatic and manual modes. An innovative addition to the drivetrain department is Low Speed Assistance – an auto cruise mode that minimises gearchanges in built-up areas.

Unlike other 6-series models, the M6 eschews the ‘Drive Dynamic Control’ toggle selector in favour of five small buttons grouped around the stubby gear lever, via which the shift speed, throttle/engine/gearbox response, stability control programme, shock absorber setting and steering feedback can be personalised. You can dial-in an individual preference, or group and store two different settings and then activate them via the M buttons on the steering wheel (ie you could have M1 set for comfort, M2 for sporty driving). On top of this, there’s the familiar MDM mode, which gives the stability control system some slack, without turning it off.

The range of electronic driving settings has been reduced to three levels: Comfort, Sport and Sport Plus. This approach works okay for the dampers, which can be amazingly supple and compliant, or quite firm and totally planted. But it’s less convincing with regard to the drivetrain, which varies from quite relaxed to rapid-fire quick but lacks a clearly defined middle ground. The least convincing character tweak concerns the variable-rate, variable-assist steering. Here, the adjustment range spans from rather heavy to quite heavy, which is not what we were looking for. Last but not least, there is DSC, which can be deactivated completely.

So, how does the 2012 M6 handle?

Sampling the spectrum of the five adjustable dynamic characteristics is a trial-and-error exercise that calls for patience and practice. On the track, finding the sportiest mixture is not exactly rocket science. On undulating, patchwork country roads, however, it can make more sense to combine the softest damper position with the fastest shift speed and the lightest steering effort.
The M6 deserves full marks for never bottoming out, for never being kicked off-line, for never losing its composure. With the chassis hardware in soft, this car copes well with broken-up back roads almost as well as the battered Citroëns, Peugeots and Renaults that are as ubiquitous in the Spanish Sierra as stray donkeys and confused sheep.
Although the M6 is almost as long as the four-door M5, its wheelbase is 113mm shorter.

The downside of this is that the high-speed stability suffers over dips, grooves and seams in the road, although on the positive side the more compact chassis is more chuckable. It turns in with the determination of an Olympic fencer on the attack and waltzes around any corner with the grace of a professional dancer, travelling between the bends with the light-footedness of a high-wire artist. Although hot Iberian tarmac after two months without rain offers about as much grip as black ice in a Bavarian winter, the BMW remained tractable and predictable in its responses.

On twisty mountain roads, the M6 invites you to explore the full spectrum of handling – from determined understeer to even more drastic oversteer. Despite a certain nose-heaviness and that substantial kerbweight, you don’t have to turn in particularly early, you can still brake heart-stoppingly late and those huge reserves of torque are always there to propel you through and out of the bend, stepping the rear end out in the process according to the settings, your mood or your skill level.
In town and on narrow country lanes, however, the new M6’s extra 45mm of girth makes the car more unwieldy. This width expansion is primarily down to flared wheel arches to take the 30mm-wider track and optional 20in rims shod with wider tyres. Our test car was fitted with 20-inchers which provide more grip, enhance the traction out of tight bends and have almost no negative effect on the commendably comfortable ride (when the dampers are set to Comfort, mind).

Is the new M6 more soothing GT or M Division-hooligan?

We also tested the M6 on the Ascari racetrack. On fresh Michelins, the 552bhp coupe emerged as a nicely balanced, sharp-handling GT that appreciates subtle inputs and a relatively defensive line. On worn rubber, deactivating DSC and lighting up the rear wheels is just about the only remedy against stubborn, terminal understeer.
While brake dive and acceleration squat are kept well in check, body roll is not alien to the M6, and working the car hard will also produce some pitch and yaw. Adaptive Drive (active anti-roll bars) might have helped here; also conspicuous by its absence is the Active Steering which works quite well in the 5-series but may not harmonise with the coupe’s shorter wheelbase.
Although the optional carbon-ceramic brakes cost as much as a decent used car at £7395, they are definitely an extra worth having. Fade-free, with no variation in performance or pedal pressure even when red hot, they give impressive stopping power and a 19.4kg weight saving over the compound steel rotors.


As regards the improved fuel consumption – officially up from 19.8mpg to 28.5mpg – it’s quite difficult to get more than 20mpg on the road, so it’s still an expensive car to run. And the purchase price has inflated along with the weight – the fixed-head M6 now costs £93,820, about ten grand more than before.
But, fiscal considerations aside, the new M6 boasts a combination of three key strengths that are quite addictive: compliance, control and confidence.
Compliance is the overriding forte of the M6 suspension which combines the best of all worlds, providing you don’t try to attack the crappiest road with the firmest setting.
Control allows you to go sideways through corners without making a complete fool of yourself – like most M cars, this XXL two-door GT is extremely deft at letting go where you can and at hanging on where you must.

Verdict

Confidence is what you, as a driver, gain from the M6’s compliance and control. We drove the socks off the raucous red rocket, storming through blind bends and over sickbag crests, often with a rockface on one side and a yawning precipice on the other. But in the M6, you don’t think: ‘Lift off… brake… caution… DSC on… omigod! Instead, you simply concentrate on the road ahead because you know that the tool in your hands is about as good as such tools get. Provided you get the settings right before setting off.

  The comments below indicate people are wanting a simpler, purer. less weighty driving experience these days. Perhaps more Toyota GT86/Subaru BRZ sort of motoring, but with a bit more zip and comfort.

It has gained 140kg. So over the old model it is one morbidly obese average height man heavier. This can hardly be called progress when every brand under the sun is looking at ways to reduce weight.

Has Car found out yet why the long term test M5 spent six weeks (or was it a month - whats a couple of weeks amongst friends) in a dealership with a fault nobody could appear to fix ?

I have no idea how much an M5 costs these days but I'd ever so slightly annoyed running around in a 1 series loan car whilst my ultimate driving machine was doing no such thing.

I'm not ageist, but this car is like putting your grandfather on steroids and a bodybuilding program. It's simply too big and heavy, and IMHO the previous 6 was the better and more interesting looking car - Bangle got it right for once.

The best 6-series would be a 640d Gran Turismo.

For CAR to be credible it needs to be balanced.  This article reminds me of the old-school car mags that just spouted the positive stuff the OEMs fed them. Can do better....
