McLaren P1

McLaren has revealed the first interior images of the production-ready P1 ahead of its debut in Geneva next month. The interior was hidden with heavily tinted windows in Paris, but these pictures show a sparse cabin with a considerable amount of carbon fiber on display. The woven wonder stuff is used for the dashboard, floor, pillars, doors and rockers while a single piece is shaped for the center stack.

Lamborghini Egoista concept

To celebrate the 50th birthday of Sant'Agata's most famous export, Volkswagen Group Design Director Walter de Silva led a team in the creation of the wild Lamborghini Egoista concept. "I am very attached to this Italian brand, being an Italian myself," said de Silva at its unveiling. "I wanted to pay homage to and think up a vehicle to underline the fact that Lamborghinis have always been made with passion, and with the heart more than the head." This single-seat, V10-powered sportscar – with Alessandro Dambrisio responsible for its exterior design and Stefan Sielaff its interior – is an extreme interpretation of the faceted aesthetic introduced by the 2007 Reventón and last seen on the Veneno shown earlier this year at the Geneva motor show.

CAR tech: who's to blame for your car's terrible fuel economy?

In early 2013 Audi lost a case brought by the Advertising Standard Agency (ASA) because of ‘misleading’ fuel economy figures used in an advert, after a customer complained they couldn’t get anywhere near the 68mpg quoted. The court case once more exposes the yawning gap between officially sanctioned mpg figures and those experienced by owners. A recent study by the Independent Council on Clean Transportation (ICCT) looked at cars sold in the UK and Europe, and discovered the difference between official mpg figures and real-world driving had grown from 8% in 2001 to a barely believable 21% in 2011.
