Volvo has just unveiled their new 5.0-liter V8 engine that will power the Polestar Racing S60 in the 2014 V8 Supercar Championship.
This engine is based on the company's 4.4-liter V8 which was used in the S80 and XC90. It has been modified and built specifically for racing in the V8 Supercar Championship by Polestar.
According to Polestar Managing Director Christian Dahl, "We have completed a number of high-rev simulations and long-distance runs and we're very happy with the figures and outcomes we've achieved. The next step is to fit the engine to the race car and continue the pre-season development timetable."
Development of the race engine began back in May 2013. The first block was completed in late October and had its first run on the dyno in mid November.
