Revolutionizing the BMW M3

BMW is less than a year away from officially revealing the fifth generation of the menacing M3, the first to receive turbocharged six-cylinder power. The performance sedan, code-named F80, is expected to appear as a lightly veiled concept at the 2013 Geneva motor show, debuting the appearance and mechanical package of the M division's eagerly anticipated Mercedes-Benz C63 AMG rival. A showroom-ready version with a production interior arrives at next year's Frankfurt motor show, BMW sources say.

BMW Gran Lusso Coupe Pininfarina teased

Does that mean the Gran Lusso previews a new 8 Series from BMW? Probably not, any more than last year’s BMW Zagato Coupe from Villa d’este spawned a new BMW, but it’s an interesting idea to revive a big V12 coupe when the rest of the car world is downsizing. BMW aren’t giving much away about the Gran Lusso beyond these few photos, but it’s clear from those tease photos that it has a makeup similar to the 8 Series, with a long nose, two doors and swooping coupe roofline.

Police get tough with Ariel Atom supercar

ANYONE with a taste for speed might fear the sight of flashing blue lights in their mirrors, but nothing could be more frightening than this! British supercar maker Ariel has created this police-specification version of its new Atom 3.5 in order to support the Avon and Somerset Constabulary’s Safer Rider campaign. The Atom PL1 has the same 350bhp supercharged 2.0-litre Honda engine, sequential gearbox and spectacular performance as the regular car – with a 0-60mph time of 2.5 seconds it can match most superbikes – but with the addition of Avon and Somerset Constabulary livery, aerodynamic pursuit lights and safety equipment.
