Jaguar XKR-S (2011) at 2011 Geneva motor show

Jaguar has turned up the power and sharpened the handling on the flagship XKR coupe for the 2011 Geneva motor show. The result: the XKR-S, claimed to be the fastest production Jaguar sports car ever. For 2011, Jaguar is returning the XKR-S to the top of the XK range. CAR readers may recall the well regarded 2008 limited edition that last carried the badge.  The XKR-S has an uprated version of the 5.0-litre supercharged V8 found in the standard XKR. Power moves up to 542bhp (from 510bhp), and torque swells to 501lb ft (up from 461lb ft) thanks to lots of ECU tweakage.

The 2013 Mazda 6 has been teased by Mazda in a series of short videos (although they were all so pointless we only ran the first one) and now Mazda has released the first official photos of the new Mazda6 ahead of its debut next month at the Moscow Motor Show. But for whatever reason, Mazda seems intent on still hiding the new Mazda6 from proper scrutiny ahead of its Moscow debut; not a single photo of the whole car, just four bits.

If so, Piedmont, S.C.-based DDMWorks might have a solution.
