One Lap of the Web: A Tumbler for Gumball, smashing supercars in China and a pedigreed race car for sale

We spend a lot of time on the Internet -- pretty much whenever we're not driving, writing about or working on cars. Since there's more out there than we'd ever be able to cover, here's our daily digest of car stuff on the Web you may not otherwise have heard about.

Porsche makes £14k on every car it sells, Bentley makes £12.7k

Porsche made £14k on every car sold in 2013 If you need an illustration of how much more profitable high-end sports and luxury cars are than mainstream cars, VW Groups sales figures demonstrate it perfectly. At the extreme ends of the profit per car spectrum, Porsche made an enviable £13,931 for every car it sold in 2013 and VW made just £615 (although SEAT actually lost £330 on every car it sold) . In fact, although you might expect the higher-priced Bentley range to make more per car than a Porsche, Bentley only managed a creditable second place on VW Group’s profit per car table, turning in £12,700 profit for every car it turned out (11,000 of them in 2013).
