Jaguar's new XK supercar is a stunning looking car, bound to turn heads wherever goes. It has the beauty and sleekness of some of the old Jaguars of the 1960s. Yet like those masterpieces, the real story of the new XK, and what sets it apart from its competitors is what lurks beneath the paintwork.
No, this time it is not some sensational engine, as it was with the XK120, but the fact that the body is made from aluminum - like the new Jaguar XJ.
The idea of using aluminum – Honda started the trend 15 years ago with the NSX, and was quickly followed by Audi with the A8 – is to reduce weight. Honda reduced a lot of weight with the NSX sports car – the body was 40 per cent lighter than if had been made from steel.
Aluminum bodies last longer than steel ones because the metal does not corrode like steel, and they also absorb crash impact well – so they are safe. Now, several auto companies use aluminum for some body parts, but Jaguar is a world leader in making cars from aluminum sheet and extrusions.
