Volvo debuts 2014 V8 Supercar engine

Volvo Car Australia Managing Director Matt Braid lifted the covers off the race engine in Sydney on December 8, with Volvo Car Group Motorsport Technical Director Martin Persson and Commercial Director Alexander Murdzevski Schedvin in attendance.

The Volvo 'B8444S' 4.4-litre production V8 has been modified and built specifically for racing in the V8 Supercar Championship by Polestar, Volvo's performance and motorsport partner since 1996.

Polestar and Volvo claim the B8444S is a truly unique design, with compact dimensions, narrow 60 degree vee configuration and a distinctive sound. The compact V8 has already undergone high-rev simulations and long-distance bench-testing with Polestar, with in-car testing to follow.
