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.

Now the AA has revealed that a survey of 29,911 of their members reveals that 40 per cent of local roads are considered to be in a ‘Terrible’ state, 34 per cent of main roads the same and just 11 per cent of local roads considered ‘Excellent’. None of which will come as a surprise to Cars UK readers; we get endless emails on the subject from disgruntled readers bemoaning the dangerous state of our roads and asking what can be done.
