The BMW M5 needs no introduction anymore and everyone acknowledges that the M5 has been, as Mr. Clarkson says also, “the ultimate sport saloon”….well, sedan as we call it here in the U.S.
So, Top Gear decided to take the Ultimate Driving Machine, that being the M5 for those that were in doubt, against the the newly and somewhat highly praised Jaguar XFR. But before we jump into the 7 minutes or so video, let’s review the two cars from a technology standpoint.

BMW M5: powered by the amazing and soon phased out, 5.0 literV10 S85 engine which produces 500 horsepower and redlines at 8250 rpm. Torque? 384 lb-ft(520Nm). Top speed is limited at 155 mph(250km/h). Official numbers show 0-60 mph(0-100km/h) figures at around 4.5 seconds.

Jaguar XFR: powered by a direct-injected and supercharged 5.0 liter V8 engine outputting 510 horsepower and 461 lb-ft of torque. Jaguar let the XFR loose with a top speed of 200 mph(320 km/h) - car tested by Top Gear stops at 155 mph. Official numbers say that the XFR runs from 0 to 60 mph in 4.5 seconds.
