To Germany, to drive the production version of the Jaguar XFR-S late-spec prototype I drove back in March on the eve of the 2014 Geneva Motor Show. 

A 550hp supercharged RWD estate with a clever limited-slip rear diff? Looking forward to it? You bet.

It gets better. The launch is in Germany. And will take in the Nurburgring – yes, tomorrow will be spent at the Nordschleife, which makes the training I did there a few weeks ago rather well timed. Particularly as the XFR-S, even on the roads around Lake Geneva, felt, shall we say, vibrant…
