Already credited with some of the world’s most desirable high-performance road cars, BMW’s M Division has excelled again – the all-new M6 Gran Coupe is without doubt one of the best cars money can buy. And worth every one of Car Showroom’s maximum five stars.
Honed by testing at the Nurburgring, this bahnstorming German supercar is of course at home on the famed autobahns and autostradas of Europe and naturally is loaded with all of BMW’s high-tech driver aids including lane-keeping assist and the remarkable top-view camera system.
In short, the BMW M6 Gran Coupe is why they invented the term ‘Supercar’.
BMW M6 Gran Coupe Overview
So you write a cheque for $299,145 and the BMW guy hands you the keys to your brand-new M6 Gran Coupe. Trust us; this will be the best day of your life – possibly only matched by the birth of your children.
The team at the M Division has taken the gloriously-styled four-door Gran Coupe and turned it into a projectile. That 4.4-litre V8 sings like nothing else, there’s technology to match the Space Shuttle and a to-die-for interior which will accommodate the aforementioned family.
And unlike some rivals, the BMW M6 Gran Coupe provides comprehensive luggage space – a practical high-performance supercar…trust BMW.
Whether you’re driving to work or have the family and related paraphernalia on-board for a trip to the country or beach-house, every drive in the BMW M6 Gran Coupe will be memorable.
BMW M6 Gran Coupe Engine
Power comes from BMW’s sonorous 4.4-litre turbocharged V8 engine – by any measure one of the best high-performance engines on the planet.
The high-revving V8 (redline 7200rpm) delivers maximum power of 412kW from 6000rpm and peak torque of 680Nm between 1500-5750rpm.
Zero to 100km/h takes 4.2 seconds and fuel consumption (combined cycle) is rated at 9.9l/100kms. To that end the BMW M6 Gran Coupe runs auto start/stop and brake energy recuperation.
Drive is to the rear wheels via BMW’s seven-speed M Double Clutch Transmission with Drivelogic and the Active M differential.
The noise of the 4.4-litre V8 at work is sublime. Unlike any other V8 really, the M6 Gran Coupe bursts into life and absolutely howls at the upper end of the rev range – astonishing.
And if that’s not enough, BMW offers an optional ‘Competition Package’ which boosts output by 11kW to 423kW and also adds a sportier suspension calibration and revised mapping for the Active M differential and steering.
BMW M6 Gran Coupe The Interior
Some have criticized the 6 Series Gran Coupe for its interior packaging – we don’t think that’s valid as, like the CLS Mercedes-Benz and Porsche Panamera, these cars are unique and you know what you’re buying. It should also be noted that BMW has extended the wheelbase of this model to provide enhanced interior space.
For us, we reckon this is one of the best interiors money can buy. Period.
We loved the ‘M’ front seats (heated and ventilated) which combine more curves than the Nurburgring for support but also staggering luxury and comfort. Rear seat passengers enjoy similarly sculptured seats, ample leg-room and a centre console.
We also loved the cockpit with the new-design M steering wheel just the right thickness, a head-up display and the usual excellent M instrumentation (so much information, colours and graphics you feel like an Airbus A380 pilot!). The compact gear lever snicks through a tiny ‘U’ shape as you move from ‘P’ to ‘D’, ‘R’ or ‘M’.
The boot is massive and the rear seat split-folds 40:60 for cargo versatility (460-litres when in-place or 1,265-litres when folded).
BMW M6 Gran Coupe Exterior & Styling
You don’t normally think of BMWs in orange paint but our M6 Gran Coupe looked absolutely brilliant. Regardless of the colour, this is one of the most exotic designs of the current era – a true European four-door coupe which turns heads wherever you go.
In fact this M6 is the first four-door coupe from the legendary ‘M’ stable so there’s the hallmark side fender ‘gills’, flared wheel-archesto accommodate the wider track, massive 20-inch alloy wheels with 265/35 R 20 and 295/30 R20 tyres and the twin tailpipes.
But there’s also substantial technology in play here – all in the name of reduced weight and aerodynamics.
Notice the roof – it’s made from carbon-fibre and there’s a recess for channeling air. Underneath the rear is a large diffuser – also from carbon fibre.
Front guards are made from thermoplastic and the doors and bonnet are aluminium.
Side view is highlighted by the low roofline and extended 2964mm wheelbase (113mm longer than the previous model for the enhanced interior space).
At the rear the beautifully-formed bootlid spoiler is a masterpiece and safety gets a real boost with a massive, high-mounted stop light running the full width of the rear window.
BMW M6 Gran Coupe On The Road
Here’s the situation: Friday afternoon rush-hour, you’re stationary in the BMW M6 Gran Coupe at the red merging light for the freeway, the light goes green and you can see the gap. Nail the throttle and the M6 simply erupts and despite all of the technology underneath and launch control, the rear tyres briefly squeal on the change from first to second as you extract your skull which is embedded in the head-rest.
Of course there’s much more to this four-door supercar…but the blistering performance of the twin-turbo V8 is a large part of it.
And the sound of the high-revving V8 has to be heard to be believed. Even when you first hit the starter button, unlike conventional engines, BMW’s 4.4-litre bursts into action with an immediate rev which signifies its intent.
Over our high-speed mountain roads test loop with every setting in the ‘S’ mode the BMW M6 Gran Coupe belied its size with an astonishing performance even in damp conditions. Change of direction was instantaneous, flat and precise and the combination of ‘M Dynamic Mode’ (raises the ESC threshold) and the Active M differential delivered just the right amount of rear-end drive enthusiast drivers look for.
Around town, BMW’s Low Speed Assistance for the seven-speed dual-clutch automatic transmission is a brilliant innovation and this ultra-high-performance German coupe ambles along smoothly with none of the ‘clunkiness’ which is a problem with other dual-clutch systems (all the more impressive given its 1875kgs weight and substantial torque). The surround view camera was brilliant when navigating our tight CBD carpark however the large 12.5-metre turning circle was at times troublesome.
BMW M6 Gran Coupe Challenges
It’s churlish to criticise this astonishing BMW but we will mention that we detected a couple of minor scrapes from beneath as we traversed just average-size speed humps. So if you have one of those steep driveways common in Sydney’s harbourside suburbs, this might become annoying.
BMW M6 Gran Coupe The Competition
At $262,645 the Mercedes-Benz CLS 63 AMG shapes as a great buy. With 386Nm/700Nm, the gloriously styled range-topper of the CLS lineup covers zero to 100km/h in 4.4 seconds (4.2 for the M6 Gran Coupe) and comes equipped with the full arsenal of AMG goodies.
We haven’t driven the Porsche Panamera but the Turbo comes in all-wheel-drive for $382,400 or S for $443,600. We suspect the Panamera might not have the rear seat leg-room of either the M6 Gran Coupe or Benz CLS 63 AMG.
