Let’s talk power and torque. Power in the new car is up 40bhp over the XFR, and torque 41ft lbs, bringing the grand total to 550bhp and 501ft lbs from the 5.0-litre supercharged V8. Amazingly, this boost in power hasn’t had an impact on the fuel consumption and emissions as they’re still 24.4mpg and 270 g/km.
But numbers like this put it toe-to-toe with Stig’s favourite sideways saloon, the BMW M5. The Jag will hit 62mph in just 4.4 seconds (just 0.1 seconds slower than the M5), and it will go a lot faster: the XFR-S is limited to 186mph, where the M5 has its reins pulled in at 155mph.
The Jags eight-speed transmission comes packaged with tech developed for the impending F-Type called ‘Quickshift’. Quickshift aims to get you the quickest and crispest shifts when you want them by anlaysing road conditions, throttle and steering input. If you’re being a bit lairy, it’ll throw cogs at you like Donkey Kong throwing barrels, but if you’re being a bit more relaxed and gentle with the throttle it will change the shift to something a bit smoother and lower down the rev band.
Frankly, if it’s anything like the last car to get the R-S treatment from Jaguar Land Rover’s specialist ETO division, the XKR-S, you’ll be shifting hard. The fast XK is rightly lauded for its glorious noise, and in the XFR-S they’ve replaced the silencer from the standard car with an X-piece and near straight-through rear pipes. Expect that characteristic crackle on the overrun.
