One Lap of the Web: Cutaway F1 cars, Bugatti's Blue Dream and building your own paint booth

Alfa Romeo Giulietta facelifted for the 2013 Frankfurt Motor Show

Alfa Romeo today only sells two regular cars, the MiTo and Giulietta.

It’s a very discreet and low-effort facelift, but the firm still hopes it’s just enough to keep the family five-door ticking over.

Jaguar to hand-build build six new 'Lightweight' E-Types

JAGUAR is bringing history to life with an incredible mission to build six ‘Lightweight’ E-Types from scratch – by hand.
