2016 Audi TT RS guns for Porsche Cayman S with £51,800 starting price

With an added 90kg, the Roadster’s 0-62mph time is a claimed 3.9sec, which is 0.3sec quicker than the previous model. Top speed for both new TT RS models is limited to 155mph, although it can be raised to 174mph.

Peak torque is 354lb ft between 1700 and an uncharacteristically high 5850rpm, 11lb ft more than the old model.

A seven-speed, dual-clutch automatic gearbox with TT RS-specific ratios is standard, along with launch control software and steering wheel-mounted shift paddles.

Chassis

The new TT RS rides on a chassis lowered by 10mm over the standard TT. Further changes include stiffer springs and dampers and standard 19in alloy wheels, ceramic brakes will be a pricey optional extra, costing around £4000.

Styling tweaks include new bumpers front and rear, wider door sills, deeper air intakes at the front end, oval exhaust pipes and a large rear fixed spoiler, although buyers can opt for a more subtle extendable spoiler. Also available are optional organic light emitting diode (OLED) tail-lights each consisting of four elements, the largest of which features the TT logo and Audi’s four-ring emblem.

This marks the first time a series production Audi has been fitted with OLED lights - we can expect more models to benefit from the tech from here on.

Audi only expects to sell around 50 models in the UK this year, with the Roadster variant accounting for around a third of that number.
