Looks like KresoF1s wife will have something to look forward too

Sitting in the passenger seat, two things immediately impress: the relentless force of the acceleration and the noise. Thanks to a tweaked version of the XK's six-speed automatic transmission, gearshifts are even faster, taking only 600 milliseconds. And with steering wheel-mounted paddles, Jaguar promises that the driver will feel plug-ged directly into the experience.

Enhancing this sense is the firm's Active Exhaust system, which features special valves in the tailpipes which open under hard acceleration. They've been tuned to allow the V8 engine's roar to enter the cabin rather than being drowned out by the whine of the supercharger. And with a thunderous, hard-edged rumble, it sounds fantastic!
