Before you read so much as a sentence more of this story, let’s get one thing clear from the outset: despite what the pictures and your preconceptions might lead you to believe, this is not in any normal sense a twin test.
If we were at all flippant about what we do on this magazine, it could quite easily be construed as such. Because we know already that Jaguar’s new XKR is a fine sporting coupe, having discovered as much when we drove it in isolation and came away breathless about its attributes.
We know too that the BMW M6 is a thumping good car, one that already operates in a broadly similar market to the XKR, in that it has two doors, comes with a prestige badge on its nose and costs more than the British Prime Minister will earn in a year...
But in the real world we know that the M6 and XKR not only appeal to very different audiences. The Jag has an automatic transmission, and is designed primarily to waft its way across the motoring landscape, albeit at a fairly serious lick courtesy of its supercharged 420hp V8 engine. The M6, on the other hand, boasts 500 rip-snorting horsepower from its V10 engine and is to the world of luxury coupes what a backhoe is to a spot of household gardening.
