Volvo C30 Polestar Performance Concept Prototype

Την πιο άγρια έκδοση του C30 έφεραν στο φως οι άνθρωποι της Polestar. Φέρει τον ίδιο 2.5 λίτρων 5-κύλινδρο turbo κινητήρα από την έκδοση Τ5 μόνο που η ιπποδύναμη έχει αυξηθεί από τους 230 hp στους 405 hp. Αυτό έχει επιτευχθεί με την χρήση μεγαλύτερης τουρμπίνας, μεγαλύτερου intercooler, custom πιστονιών, μπιελών και εκκεντροφόρων. Επίσης αλλαγές έχουν γίνει τόσο στις αναρτήσεις (Ohlins) όσο και στα φρένα (Brembo) με το σύστημα τετραδιεύθυνσης Haldex να παραμένει ως είχε και στην αρχική έκδοση. Πάντως η παρούσα έκδοση δεν περιλαμβάνεται στα πλάνα της εταιρείας για παραγωγή (παραμένοντας στην Τ5 ως την δυνατότερη έκδοση).

Volvo C30 Polestar Performance Concept Prototype

Premiere for concept car from Volvo Cars' official Racing and Performance Partner

This weekend Volvo Cars and Polestar enter their fifteenth consecutive motorsport season in the Swedish Touring Car Championship (STCC) as reigning champions. But even before the racing cars exit the pit for the weekends' first practice session, Polestar now present the ultimate Volvo car for the street.

Main objective with the Volvo C30 Polestar Performance Concept Prototype is to explore what happens when racing engineers and designers get free hands to build a street car without any limitations set by a specific racing regulation.

Polestar has a long and successful competition history with Volvo, racing with 850, S40, and S60. In 2009, Polestar won the STCC for Volvo Cars with the C30, a car they developed completely from scratch.
The close relationship between Polestar and Volvo Cars in testing and development has lead up to Polestar receiving the responsibility to develop Polestar Performance Engine Optimization Products as a complement to Volvos standard cars.

These products are sold through Volvos dealers on several markets and are the only engine optimizations for Volvo cars covered by Volvos original warranty and where the certified fuel consumption and emissions remain unchanged.

With the Volvo C30 Polestar Concept Prototype, Polestar aimed to build further on the strong driving characteristics of the standard C30 and at the same time illustrate the link between the racing cars and the Polestar Performance products.

The car is based on Polestars unique experience from developing the Volvo C30 into a winning race car. The interior and exterior design reflects Polestars know-how on 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 car will premiere for the public at Gothenburg Motor show April 22-25.
