Geneva Show 2014: Hot Audi S1 arrives

ONE OF THE smallest cars on the Audi stand at the Geneva Motor Show was also grabbing the most attention, as the German firm unveiled the new S1. Based on the A1, the smallest Audi in the range, the S1 also takes inspiration from the strictly limited edition A1 Quattro that appeared in 2012. Packing a turbocharged 2.0-litre engine under its compact bonnet it is comfortably the fastest A1 in production, with a top speed limited to 155mph and 0-62mph taking 5.8 seconds.

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.

Ferrari F70 takes test laps

It's a strange world we live in when, even in my short-to-medium lifespan, we've gone from the 1980 Ferrari 308 GTSi making either 205 or 214 hp—depending on who you're asking—to the Ferrari F70, which is rumored to make 950 hp with its V12 and KERS system. I would put an Excel graph here, but just imagine a line going up at a 45-degree angle to infinity. With all of that in mind, here's about five minutes of the camouflaged supercar flying around the test track with fantastic audio of the Italian stallion in action.
