The new Peugeot RCZ R is set to make its debut at the Goodwood Festival of Speed this weekend.

Powered by a new 1.6-litre THP engine developing 270bhp and 330Nm of torque from 1,900 rpm to 5,500 rpm, the RCZ R can accelerate to 62mph in 5.9 seconds and on to a 155mph electronically-limited top speed.  It can also achieve 44.8mpg on the combined cycle, while emitting 145 g/km of CO2.

New pistons were developed with Mahle Motorsport, cooled by two jets, and connected to uprated con rods.  Bearings with a special polymer coating were also used.

Peugeot says weight reduction has been its mantra for the RCZ R’s development, with 17kg removed in comparison to the standard model.

The suspension has been lowered by 10mm, with revised springs and dampers, as well as a thicker anti-roll bar.

A Torsen differential feeds the power to 19-inch Goodyear Eagle F1 Asymmetric 235/40 R19 tyres, while the brakes, upgraded to 380mm x 32mm discs mounted on aluminium hubs and grabbed by red calipers, provide the stopping power.

Outside, there’s a new fixed rear spoiler and diffuser, chromed exhausts and an exhaust system reworked for both performance and sound.  There’s also subtle red ‘R’ badging.

It’s available in four colours – Moroccan Red, Nera Black, Mercury Grey and Opal White – with a choice of satin or gloss roof treatments, decals and mirror shells.

Inside, there’s an array of ‘R’ logos, such as on the Nappa leather/Alcantara sports seats, as well as red stitching on the dashboard, steering wheel, gear lever, door panels and seats.

A formal reveal will take place at Frankfurt, and the RCZ R will go on sale in early 2014.
