July 1, 2006 Jaguar yesterday revealed its new supercharged sports car – the Jaguar XKR. Building on the XK that debuted in 2005, the XKR will be available as a Coupe or Convertible. Like the XK model, the new supercharged XKR makes intelligent use of practical, modern technology such as an industry-leading aluminium monocoque structure that results in a light and yet very stiff body. An uprated 420bhp (SAE) supercharged V8 engine and class-leading calibration of a state-of-the-art, six-speed automatic transmission deliver accessible, real-world, high performance of 0-60mph in 4.9 seconds, 50-70mph in just 2.5 seconds and has an (electronically limited) top speed of 155mph. The all-aluminium body construction delivers a lighter, stiffer car, with excellent agility. At 1665kg, the Coupe is 70kg lighter than its predecessor, while the 1715kg Convertible is 100kg lighter than the previous convertible XKR.
