Jag XKR-S GT vs SRT Viper TA
542bhp Brit brawls with 631bhp of American muscle. But which will come out on top?
Posted: 03 Apr 2014
Now it's time to find out for real, as we've just arrived at one of the fastest race tracks anywhere in the world - Willow Springs International Raceway. This 61-year-old, 2.5-mile facility has hosted everything from Formula One cars - Nigel Mansell tested his Lotus here in 1983 before the Long Beach Grand Prix - to Superbikes and has a track record of one minute six seconds, an average speed of 136mph.
I've already driven the TA on this circuit during its launch event. So today, to keep things fair, we are going to be using the adjacent Streets of Willow track instead. It's shorter, narrower and more twisty than the big circuit, but it'll help us dig into each car's abilities more thoroughly and at more sane speeds. On the big circuit, you can hit Turn Eight - the fastest corner on any race track west of the Mississippi - at over 145mph in the Viper. So you're mainly concerned with staying alive rather than how the car is behaving.
