How good has it been on the jobs it has immediately been thrown into? Across PH and its sister titles it has been group tested against a Mercedes-AMG E63 and Cadillac CTS-V (and won), videoed alongside an E63 (and won), videoed along with a new Alpina B5 (still to be screened, but guess what?), it has been signed-up for the PH trip to Le Mans, and it has been through a full Autocar Road Test figuring session whose results are, also, as I write, still to be published.
There's a lot that's remarkable about those numbers, but mostly it's that they arrive despite the fact that, when all's said and done, this is a car that tips the scales at 1,940kg and still does all that a BMW 5 Series does.
It, as standard or optionally, seats five in great comfort, is nearly five metres long, has a 530-litre boot and split-fold (heated) rear seats, and a 68-litre fuel tank from which it can sip unleaded at 28mpg (though 21 is more likely, and 7.5 is possible).
As tested, then, it costs £101,900, thanks to a fair few options on top of the £87,940 list price. Both of which are a lot but, then, it does do quite a lot. It rides comfortably enough via its coil springs with adaptive dampers. It has grip and traction to spare in its standard 4WD mode, rather less in RWD, and overtakes things on a whim thanks to the engine's easy-going, boosted thrust and. It's both supremely easy and at the same time quite exciting to spend time in.
