Not your ordinary kind of taxi though because this one will take you round the Nürburgring Nordschleife quicker than a black cab can get you from Waterloo to the Embankment.
This is the log wheelbase XJ Supersport from Jaguar that is fitted with the Sport and Speed Pack options which removes the speed limiter to let the 510PS V8 stretch its legs to 174 mph (278.4 kph).
Jaguar’s ‘Nurburgring Taxi’ follows in the footsteps of BMW who’s M5 driven by a certain Ms Schmidt attracted a lot of attention to the fact that those who would rather be driven than drive the ‘Ring themselves could do so courtesy of a very experienced driver in a slightly modified road-car.
The XJ taxi which has been developed at Jaguar’s Nordschleife engineering test facility looks suitably sinister in its matt grey paint finish and the usual leather interior has made way for four snug-fitting racing seats with harnesses plus a roll-cage just in case things get a bit lairy on the track.
Driver – follow that M5 and don’t spare the horses!
