Concept Car of the Week: Ford 021C (1999)

As Australian-born designer Marc Newson this week joined Apple, we can only wish that he brings with him the same smart-yet-playful approach as he did with his radical Ford 021C concept. Presented at the 1999 Tokyo Motor Show, the project began when Marc Newson was commissioned by Ford global design director, J Mays, to create an innovative interior. Their mutual passion for design and their enthusiasm led to a much larger project and Newson eventually delivered a complete working prototype.

Renault Twin’Z Concept previews 2014 Renault Twingo

The Renault Twin’Z Concept, designed by British designer Ross Lovegrove, is an electric city car previewing the 2014 Renault Twingo. The Renault Twin’Z Concept is a small, just 3623mm long, urban runaround with a small electric motor good for 67bhp and 167lb/ft of torque  and weighing in at 980kg, complete with a fairly sophisticated double wishbone suspension and relatively long wheelbase with a wheel at each corner stance. The Twin’Z is very much a concept car - designed by British designer Ross Lovegrove – and comes complete with the usual concept fripperies like electric suicide doors, cameras instead of rear view mirrors, sweeping LED lights, a solid crystal rear spoiler and big, complicated alloys.

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.
