We’ve seen this XFR-S prototype at the Nurburgring before, but this time it has sprouted a huge wing on the back, bigger even than the one found on the XKR-S coupe! They’ve tried to camouflage it with a bit of white tape, but there’s no missing it, is there!
If you thought the new BMW M5 is not aggressive enough for you to swap in your E60, this might be the perfect solution. Instead of discrete bodywork, the XKR-S has a large diffuser, visceral exhaust note and a huge gaping front end. What’s more, this is the only stock sedan we know that rides on low profile performance tires like these.
The power for this all-mighty machine will come from the same 5.0-liter supercharged V8, but over the standard 510 PS (503 hp) of the regular XFR, this will have an extra 40 horsepower and 70 Nm for a grand total of 542hp (550PS) and 680Nm (501 lb-ft) of tarmac twisting power.
