Peugeot RCZ R with 260bhp to debut at Goodwood FoS

The Peugeot RCZ R (concept pictured) will debut in July at Goodwood We saw the first glimpse of the Peugeot RCZ R at the Paris Motor Show when Peugeot revealed the RCZ R as a concept at the same time as it revealed a facelift for the RCZ range. At the time we said we expected the RFCZ R to turn from concept to reality by the end of 2013, and today Peugeot has revealed that the RCZ R will make its debut at the Goodwood Festival of Speed in July before going on sale. The production RCZ R gets a tweaked version of the 1.6 litre turbo found in other RCZs (and other PSA/BMW cars) with 265bhp and the same range of styling tweaks the regular RCZ facelift got last year.
