Volvo has unveiled the new V8 engine that will power the Volvo S60 V8 Supercars in next year’s season. The engine has made its debut at the Sydney 500 event, which takes place this weekend.
Detailed with lots of carbon fibre, the engine is based on the 4.4-litre naturally aspirated Yamaha unit that has powered a number of road-going Volvo vehicles over the years. It is of course completely rebuilt and tuned ready to take on the local touring car championship next year.
With Volvo joining the Aussie Ford and Holden battle, the V8 Supercars series will have five different car brands involved in the 2014 season. Volvo joins the recently introduced factory Nissan team and the Mercedes-Benz entrants from Erebus Motorsport and Stone Brothers Racing.
The Volvo team, called Volvo Polestar Racing, is a partnership set up by Volvo, Polestar, and Garry Rogers Motorsport. The group will apply an S60 body to the Car of the Future platform, along with a sophisticated V8 engine.
As you can see in the image, the V8 will use eight individual throttle bodies which are fed by eight carbon fibre intake trumpets. It will also use double overhead camshafts capped by carbon fibre rocker covers. Capacity is taken out to the 5.0-litre regulations.
