Do you want a tiny James May running round your Smartphone?

James May Science Museum App If you fancy the idea of Top Gear’s James May teaching you science then a new App from the Science Museum is right up your street. Regular Top Gear viewers may remember Messrs Clarkson, May and Hammond taking on ‘Art’ a few seasons ago to teach Northerners how to appreciate galleries. Part of what they did – apart from stealing ’Footballists’ to populate the gallery – was an audio guide for the art gallery tour narrated by James May.

Bonhams' Greenwich auction will show Italian rarities

The biggest star of Bonhams' seventh annual Greenwich auction will be the 1975 Lamborghini Countach LP400 Periscopica shown above, a pristine early example of the legendary wedge with a single owner and less than 10,500 miles -- its roof carried a groove cut into the sheetmetal that allowed light to hit the rearview mirror, providing a still-laughable semblance of rearward visibility. Of course, the door is always preferable. Just 158 LP400 Countachs were ever produced, before the firm moved on in 1978 to the outrageously styled LP400S.

New BMW M3 and M4 engine secrets laid bare

BMW's M division has lifted the veil of secrecy on the inline six-cylinder engine bound for its upcoming M3 sedan and new-to-the-range M4 coupe and convertible, revealing a potent twin-turbocharged 3.0-liter direct injection gasoline unit that produces an official 424 hp at 7,500 rpm and what officials describe as "significantly more than 369 lb-ft" of torque. The newly developed engine, known under the internal codename S55 B30, shares its 84.0 mm bore and 89.6 mm stroke with BMW's standard turbocharged 3.0-liter in-line six-cylinder direct-injection gasoline mill, the M55 used across the German car maker's lineup, endowing the aluminum block unit with an overall swept volume of 2,979 cc. This represents a sizeable 990 cc reduction on the engine BMW's M division's new unit replaces, the S65.
