BMW Z4 sDrive 35is (2009) at Detroit motor show 2010

These are the first official pictures of the new high-performance BMW Z4 sDrive 35is, unveiled today at the Detroit motor show. A bit of a mouthful (that's BMW's new nomenclature for you), but it's essentially the fastest, hardest Z4 to date since the recently departed M roadster curled over and died.The Z4 sDrive 35is uses Munich's existing 3.0-litre twin-turbo straight six, tweaked to produce 335bhp and 332lb ft of the twisty stuff all the way from 1400-4500rpm. That's one flat torque curve, and a 29bhp jump over the regular sDrive35i.

Bentley Continental GT3-R (2014) first official pics

By Damion Smy First Official Pictures 17 June 2014 12:00 The Bentley Continental GT3-R is the fastest accelerating Bentley ever built. It’s a road-gong version of the car that stormed to victory at Silverstone last month, the Continental GT3, and ticks off 0-62mph in 3.8sec: this is some grand tourer The 4.0-litre twin-turbo V8 that’s just been introduced into the Flying Spur saloon has been wound up to a heady 572bhp, with a stonking 516lb ft combining to make this svelte coupe the fastest accelerating Bentley production car ever built, and a whopping 0.8sec better than the V8 S model. The GT3-R is not the fastest Bentley, though, with its top-end only 170mph (virtually walking pace, really), but the eight-speed ZF gearbox and final drive have been tuned to make this car a corner carver, as opposed to a top-end tourer.
