Audi S1 at Paris

The Audi S1 will have a Paris Launch (A1 Wörthersee Concept pictured) It’s getting on for a year since we reported that – despite some saying it wouldn’t happen – Audi were planning at least a warm version of the A1 and had on the drawing board the Audi S1 to take on the MINI Cooper. So it’s not a shock that we hear Audi are planning on bring the S1 along to Paris for a reveal before getting the S1 on the roads by the second quarter of 2011. Expect the usual Audi S bits in the mix  - bigger wheels, fettled suspension, beefed-up brakes, body kit – and power in the S1 to come from the S/C turbo 1.4 TSI found in the VW Polo GTI, although the S1 may just get a tweaked version of the engine as befits its higher standing in the VW hierarchy with a bit more than the 178 horses the Polo GTI manages.

Tesla touts top sales at Detroit auto show

Tesla credits the "exceptional cold weather performance" of its Model S for 20 percent-higher-than-expected Q4 sales of 6,900 units, bringing total Model S sales worldwide to 25,000 so far. In fact, Tesla says its sedan does so well in the snow that the rear wheels are the only ones that need any torque. "This car performs outstandingly in winter conditions," said Tesla vp of vehicle engineering Chris Porritt in a video released the day of the Detroit Auto Show.

McLaren 650S Sprint (2014): the gentleman racer’s Macca

By Tim Pollard First Official Pictures 11 August 2014 17:59 Visitors to the upmarket Pebble Beach festival this week will witness the world debut of a very special McLaren track-day special: the new 650S Sprint coupe. The clue’s in the name: the Sprint is a track-only version of the 650S, designed for wealthier fans to go on track days and race at junior levels. It slots beneath the full-blown 650S GT3 racer – this is more a My First Track Day Special for wealthy owners after an amateur race-day weapon.
