Shopping for a fast sports saloon? This test conducted by EVO will make it easier for you to make the final decision. This is a 1000m acceleration test to which one of these fine Swiss army knifes – Porsche Panamera, Mercedes E63, the new BMW M5 and Jaguar XFR – is faster. That’s probably the most important factor, because if it’s not for the speed you can save yourself tens of thousands of Euros and buy diesel-powered versions of these cars. So buckle up, and hit the jump to watch the race.
