Even if you're not a fan of the boot-mounted Boeing appendage, or the distinctly un-Jag nuclear blue paint, you'd be utterly certifiable not to get The Fizz from the XFR-S' exhaust note.

OK, so it doesn't play a festive ditty, but the 5.0-litre supercharged V8 stapled to some free-flowing pipes sure sounds pretty at full chat. Even more so when you remember that this 550bhp M5 botherer can hit 100kph in 4.4 seconds, and go on to a limited top speed of 300kph.

Best sounding Jag ever, TopGear.commers? Or does that honor still belong to the Eagle E-Type?
