One Lap of the Web: Mock the Week Edition

-- Mazda Europe designer Peter Birthwhistle talks about the future of Mazda: potential hybrid and electric powertrains for the Skyactiv-obsessed company, and how we'll all be driving Mazda-branded pods in the 22nd century.

No, it's the exhaust systems on those Skyactiv engines that force a longer, larger hood compartment, and the "long, flowing looks" not usually found on FWD engines.

THE UPCOMING replacement for the world's fastest luxury car could be too quick to test, according to a motoring magazine. Bugatti is looking to replace the famous Veyron with a new, faster model that could reach speeds of around 286mph, but questions have been raised by weekly title Autocar over whether the facilities will exist to test it to its maximum. Not only is space a concern for the 1,500-horsepower concept, because it will need much longer straights than the Veyron, but also tyres are an issue.
