Unfortunately, there’s no additional power on this model, which means the supercharged 5.0-liter V-8 found under the hood delivers the same 550 horsepower and 502 pound-feet of torque as the lesser XKR-S. But that doesn’t really matter, as British journo Chris Harris recently found out when sampling the car for the latest episode of Drive. Bad weather meant he couldn’t really drive the car very fast but he does manage to get it sideways a few times, and the engine does sound a treat.
Starting with an XKR-S, which is already no softy, the engineers at ETO widened the track, added more negative camber, increased the speed of the steering and toughened up the suspension.They also added a host of aero aids while also uprating the brakes.
All of these upgrades come at a steep cost, however. The $174,000 starting price of the XKR-S GT is knocking on supercar territory.
