Concept Car of the Week: Porsche Tapiro (1970)

By the late 1960s it was time for Porsche to create a new car that would replace its ageing entry-level model, the 912. Its sister company Volkswagen also needed a sports coupe to replace the Karmann Ghia and so the two brands joined together to develop what would become the Porsche 914. These days the 914 holds something of a ‘cool factor', generally considered as the ‘black sheep' in Porsche history.

Audi R18 TDI dominates Le Mans 2011 test day

Le Mans echoed to the sound of racing cars on Easter Sunday as teams took part in the sole scheduled test day, and Audi's new R18 coupe dominated the LMP1 class. Le Mans 2011: classes and rules changes The Automobile Club de l'Ouest (ACO), the organisers of the annual 24-hour race, made several changes to the competition classes and technical specifications for Le Mans 2011, aimed at reducing costs, raising lap times and ending the dominance of turbodiesel endurance racers. Out went V10 and V12 engines in the LMP1 (Le Mans Prototype) class, and in came new capacity limits for all engines, intake restrictors and lower turbo boost limits on existing turbodiesels. Naturally aspirated petrols units are now limited to 3.4-litres, turbo'd petrols can be no bigger than 2.0, and turbodiesels are restricted to 3.7-litres.
