BMW 6 Series vs Bentley Continental

What's the difference?

What happens when you struggle to sell an odd-bod, not-quite-a-coupe, sort-of-a-hatchback, almost-an-SUV model? Well, sometimes it gets axed, and replaced with a new model that bears a new name.

That's pretty much it in a nutshell for the BMW 6 Series Gran Turismo, which was formerly the 5 Series GT. It essentially takes the place of the 6 Series Gran Coupe - an alternative to the regular 5 Series sedan that's more attainable than a 7 Series limousine.

Confused? It's not as difficult as all that sounds - you just need to know that this model, the 2018 BMW 6 Series Gran Turismo, is supposed to offer a neat alternative to the go-to family luxury car or SUV.

I spent some time in the entry-level 630i to see if it can deliver on that promise. In fact, I spent more than 24 hours driving the BMW 6 Series GT over the past week, and I don't have a sore back, I haven't been left scratching my head over the intended purpose, I haven't been uncomfortable, and I haven't been left wanting for much.

Close your eyes for me and try to picture a two-door vehicle with a thumping V8 engine, 575kW and a whopping 1000Nm on tap, a 0-100km/h burst of 3.2 seconds and a top speed of 335km/h. Does it look like a Ferrari in your head? Something else Italian, or German perhaps?

Well, what if I tell you it also weighs 2.5 tonnes. Are you imagining a luxe SUV with the rear doors removed, perhaps? Think again, because what we’re discussing here is arguably the very best of Britain (albeit German-owned), the all new and highly impressive Bentley Continental GT Speed.

Gone is the famous and fabulous W12 engine, never to return (Bentley was long the world’s biggest maker of 12-cylinder engines, henceforth it will make exactly none), to be replaced by the one and only power plant the company will now offer, in various tunes, in all of its ICE cars (yes, a Bentley EV is coming, of course).

All that torque isn’t just from the big 4.0-litre V8, it’s also an 'Ultra Performance Hybrid', which will allow you to drive up to 81km in fully silent electric mode, should you be so boring.

We flew to a posh and very private members-only race track in Japan to find it out if this really is, as Bentley suggests, the everyday supercar.
