Volvo C30 Polestar Concept

…that produces more than 300kW of power.

It uses the same engine as the incredible Ford Focus RS, just tweaked a little more by Volvo's racing partner Polestar.

The concept was first shown at the Gothenburg Motor Show last year.

Although Volvo describes the car as the ultimate street machine, it unfortuately has no plans to put the hyper C30 into production.

That's a shame because it's cars like this that the company needs, not the safe but mainly boring cars that it has been producing for years.

Polestar has successfully campaigned a vesion of the car in the Swedish Touring Car Championship (STCC).

Volvo said the main objective in building the prototype was to explore what happens when racing engineers and designers are given a free hand to build a street car without any limitations set by a specific racing regulation.

The Volvo C30 Polestar Concept Prototype is based on Polestar's unique experience from developing the Volvo C30 into a winning race car.

The interior and exterior design reflects Polestar's know-how with the C30's aerodynamic and driving properties derived through several years of development and testing – from computer simulations, to wind tunnel and race track testing.

The T5 2.5-litre turbocharged five cylinder engine is fitted with a larger intercooler and KKK 26 turbo, with modified pistons, conrods and inlet camshaft.

It produces 302kW of power and 510Nm of torque, with drive fed to all four wheels through the Haldex all-wheel drive system. The car rides on Ohlins shock absorbers and springs, and 19 inch BBS alloys fitted with 235/35 Pirelli P Zeros.

A more responsive steering rack with 2,25 ratio, along with six piston Brembos up front and four piston Brembo brakes at the rear.

Polestar has a long and successful competition history with Volvo, racing with 850, S40, and S60 and in 2009 won the STCC with the C30, a car they developed completely from scratch.

The close relationship between the two companies has seen Polestar given responsibility to develop Polestar Performance Engine Optimisation Products to complement to Volvos standard cars.
