Audi, the inventor of TDI, is about to blaze another trail in the field of engine manufacture with the A3 TDI clubsport quattro, a one-off show car featuring the most extreme incarnation to date of its advanced four-cylinder TDI engine.

The long awaited new Mercedes C-class was finally unveiled last year, and has already established itself as a firm favourite with fleet buyers.

The new Audi A4 hits the showrooms early in 2008 and needs to make a big impact in the compact executive market. Competing with the big selling BMW 3 series and the recently launched new Mercedes C-Class, the A4 is in illustrious company.
