Watch for Volvo Polestar's V8 Supercar to be unveiled this Thursday, February 13.
The 5.0 litre V8 unit will power the S60 entries for Garry Rogers Motorsport next season, marking Volvo’s return to Australian Touring Car Racing.
The new race engine is based on Volvo’s B8444S 4.4 litre production V8, and like the Nissan and Erebus Mercedes-Benz entries of this year, the new Volvo unit promises to bring its own unique sound to the series.
Unveiling the engine at the beginning of this weekend’s final V8 Supercar round for 2013 around the streets of Sydney Olympic Park, Volvo Car Australia boss Matt Braid said the Swedish carmaker had spared no resources in building its new race engine.
“As the first luxury car manufacturer to field a factory team in the V8 Supercar Championship, we’re delighted to share this milestone moment with you and reveal our race engine for the 2014 V8 Supercar season,” Mr Braid said.
“The race team at Polestar have worked hand-in-hand with the engineering team at Volvo Cars to design, build and develop a race engine in Gothenburg, Sweden, to compete in Australia’s premier motor racing category.”
Managing Director of Polestar, Christian Dahl, said work commenced on the race engine in May, with its first-ever dyno-test last month offering pleasing results.
