The interior is gutted to save weight and to make way for a welded-in roll cage (the previous Clio Cup has a less rigid bolt-in cage), and a revised aero package provides around 40kg of downforce at speeds above 193km/h.
Without its interior and other non-essential items like air conditioning, the 2014 Clio Cup weighs just 1065kg. That's nearly 140kg less than a showroom-spec Clio RS.
The Clio Cup's 1.6 litre turbo has been massaged by Oreca Magny-Cours and Cosworth to produce 165kW of power and 270Nm of torque, an 18kW and 30Nm gain over the road-going Clio RS.
Renault also replaced the RS' twin-clutch EDC transmission in favour of a Sadev six-speed sequential gearbox, which can be ordered with paddle shifters or a conventional sequential shift lever.
Other features include a AP Racing/Brembo brake package, which marries 320mm ventilated AP rotors with four-piston Brembo rotors at the front, and and puts 260mm solid discs at the rear.
The ZF Race Engineering dampers are fully adjustable, and suspension geometry can also be tailored to particular tracks. The Clio Cup comes equipped with 17-inch Speedline wheels as standard, shod with either Dunlop or Michelin race rubber depending on race series.
The Clio Cup's interior may be spartan, but it's got all a racer needs.
A fixed-back Sabelt racing seat holds the driver firmly in place, and most major controls have shifted from the indicator/wiper stalks to the alcantara-clad steering wheel.
A Cosworth Electronics digital dash displays speed and RPM, and can also call up data on lap times and track layout.
Want one? You'll need to shell out around AU$57,000 for the car, and you'll also need to compete in either the UK or European series of the 2014 Clio Cup.
Australian availability for local racers has yet to be confirmed, however the Clio RS road car is not expected to arrive here until the start of 2014.
