Much as I foolishly did when I first drove the new BMW 6 Series convertible, I came to the Gran Coupe with some unfortunate preconceptions. Too big. Too bloated. Too much of a plutocrat barge for this day and age. A €100k car in 2012 Ireland? C'mon, that's like €30k more than Audi asks for the A7 or Mercedes wants for a CLS. Etc etc. And so on.But, just as I did with the cabrio, I (spoiler alert) came away utterly loving the car. Which just goes to prove two things. One, never underestimate BMW and, two, review the car on the road, not the car in your head...
So, what is a Gran Coupe? Well, it's the latest in a burgeoning line of car makers either adding extra doors to existing two-door coupes or chopping the rooflines of existing saloons to create saloon-coupe hybrids. The idea is to create cars with the looks and panache of coupes with most of the easy-access practicality of saloons. Thus the afforementioned CLS and A7 but also the A5 Sportback, the Volkswagen CC and sundry others currently in development.
In the specific case of the Gran Coupe, BMW has taken the standard 6 Series shell, given it a 113mm wheelbase stretch (taking to just beyond the 5-metre long mark) and crammed in a couple of extra doors. The result is a long, low wide chop-top that manages to avoid looking like a 6 Series that's turned back, Cinderalla-at-midnight-style, into a 5 Series and is frankly, pretty gorgeous. Especially in the black of our test car, which in true Father Ted fashion, wasn't actually black at all but instead very, very, very, very, very dark blue. It's gorgeous and I'm going to shut up now and just let you go and look at the photos.
Done? Good, then I'll continue...
Behind the sharks-nose grille and lights likes the 40d diesel engine, actually a 3.0-litre straight-six with twin sequential turbos – a development of the engine we've been familiar with for many years in the 535d and the old 635d. Now, it comes with some interesting figures. 313bhp is a good start but 630Nm of torque is even better again and those are combined with a 5-odd-secs 0-100kmh, claimed 50mpg fuel economy and 148g/km of Co2. That is frankly a remarkable set of figures and proof once again that BMW's chief engine designer is actually a Mr. Potter, a youthful man with glasses who displays his diploma from Hogwarts with quiet pride.
It's a truly stunning engine to be in control of, so much so that it eclipses the more headline-grabbing 560bhp petrol V8 from the M5 in my mind. Power arrives in a near-silent rush from below 1,500rpm, shunting the 630d forward in a manner that suggests that the Atchison, Topeka and Santa Fe express has derailed and smacked you, silently, up the backside. The engine only makes you aurally aware of it at higher rpm, where instead of a diesel rattle, you get a creamy, slightly rough-edged snarl. It's lovely. And addictive. Rather like cream itself.
As for economy, well almost needless to say we couldn't match BMW's claimed figure but our average, which hovered in the mid-sevens in terms of litres burned per 100km traveled (a solid 45mpg-ish) still seemed pretty good, and if we also failed to match BMW's claimed touring range of 1,300km, then a solid 8-900km still seems achievable.
Inside, in spite of the Gran Coupe's extra length, the cabin still feels intimate and tight fitting. The dash and centre console seem to bulge and swoop almost organically around the driver, allowing you to settle deep within the car, wheel pointing straight at your chest. The standard leather trim is gorgeous and inviting and the seats prove endlessly comfortable, something the old-shape 6 Series missed out on.
In the back, while it's not surprisingly not as commodious as a 5 Series, the Gran Coupe is absolutely fine for both head and legroom and unless you're the star player for your local basketball team, you should be able to get very comfy. That practicality is backed up by a 460-litre boot which should be adequate for most purposes.
To drive, that stretch in the wheelbase seems only to have improved the dynamics relative to the standard 6 coupe. Not that the standard car is lacking in any sense but just that the Gran Coupe seems to give you a wider range of options. Selecting comfort from the little toggle switch by the gear selector for the excellent 8-speed automatic transmission seems to be the best option for Irish roads. Sport is fine and won't knock your fillings out, but Comfort just gives you that extra little sense of flex that turns tackling an Irish back road from a chore to a delight. In spite of its size, the Gran Coupe can be cornered on a pin and placed to within millimetres of your desired trajectory. The steering, in any of the four modes, is always a little bit wooly and artificial feeling (something not helped by BMW's continuing insistence on fitting its M-Sport specced cars with fat, over-stuffed steering wheel rims) but the reactions of the chassis itself are wonderfully well balanced and its these that you learn to exploit, and never mind the faintly disappointing steering.
I had expected many things of the Gran Coupe, few of them good. Given the massive extra expense it asks buyers to stretch too relative to an Audi A7 or Mercedes CLS, I was certain ahead of the fact that BMW was overstretching itself, and I remain convinced that the Mercedes actually has the better sorted chassis. But the Gran Coupe, thanks in no small part to its wonderful engine, is actually a star performer and goes so far to justifying its lofty six-figure price tag that you almost begin to forgive the expense. Fabulous to drive, irrepressibly grunty and bewitching to look at, it may be a niche within a niche but that's a niche I'd happily squeeze myself into.
Actually, on a final note, the best drive I had in the Gran Coupe was not up some twisting coast road (although I did do that and it was fabulous) but a gentle 50-60km pootle to my local cinema and back. The Dark Knight Rises, the new Batman film was on, and comic book nut that I am I simply couldn't resist. Coming back out after nearly three hours of Bat-tastic Batmanery and plipping the lock on the low, dark, glowering Gran Coupe felt just perfect, and for the briefest of moments, I was Bruce Wayne. And that might just be the moment at which the Gran Coupe's price tag begins to look worth it...
