Volvo has unveiled the engine that will power its Volvo Polestar Racing S60s in the 2014 V8 Supercars Championship.

Announced in June, the racing engine has been modified and built by Volvo’s performance partner, Polestar, in collaboration with the engineering team that developed the Swedish car maker’s upcoming ‘Drive-E’ family of four-cylinder engines.

The engine is based on the brand’s 4.4-litre ‘B8444S’ V8, which was developed for Volvo by Yamaha and has been built in Japan since 2005. The V8 was available in Australia in the XC90 SUV from 2006 and in the S80 sedan from 2007 before being phased out of the local line-up in 2011.

Modified to a larger 5.0-litre capacity to meet the race series’ regulations, the aluminium engine features a 60-degree vee configuration and double overhead camshafts.

Development of the race engine began in May, with the first block completed in October and the first dyno run conducted in mid November.

Polestar managing director Christian Dahl says motorsport fans will instantly recognise the distinctive soundtrack of the S60s’ V8.

“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,” Dahl said.

“The next step is to fit the engine to the race car and continue the pre-season development timetable.”

Volvo will become the fifth manufacturer on the 2014 V8 Supercars grid – joining Ford, Holden, Mercedes-Benz and Nissan – when it debuts at Adelaide’s Clipsal 500 in February.

    60 degree V8. Wonder if it has offset crankpins to make the phasing equal?

    • Roadtard

      Would 90 degrees offer a lower COG? Happy to be enlightened by someone more knowledgeable.

        Personally I think the difference in cog would be minute, same as the difference between pushrod and dohc

        They use weights on the block to balance them. Wouldn’t be much in it though.

    • Phil

      if they don’t want it to shake itself to bits, it must have offset crankpins and counter-rotating balance shafts, as did the production version.

    I hope it’s a winner.

    I can see all the same mounting points for ancillaries as my Volvo V8. The two mounts for alternator at the front right, yet they’ve gone for an external one. Can see the belt tensioner mount, yet a complete separate setup, for obvious reasons.
    It’s nice to know they’re using the basics from the road car, as it’s such a gem of an engine. I wonder where I can get some of these parts…

    did not Volvo said this year how V8 are all dinosaurs!?!?! well i dont expect them to be better than Nissan and MB already are

      It is a bit of a joke. The 4.4l Yamaha V8 has been long discontinued not just here in Australia, but in every market worldwide in all models. In another 12-18 months even the existing 5 and 6 cylinder engines will have been withdrawn.

      • Sydlocal

        So in otherwords it fits right in with V8 Supercars considering the ‘Ford’ and ‘Holden/Chev’ engines haven’t been used in a production application for many years either!

    • Dale McKewen

      It is still going alright in the Noble M600. That car uses the same Yamaha V8 and is one of the fastest cars on the planet…

  • new world

    Can believe car of future is running a v8 5lt when every other racing category are down sizing engines . I thought they would go down to v6 turbo or 5 inline turbo with kers and drs like Dtm and F1 . How can they run around with these big engines and get support from fans . Just crazy

      It’s V8 supercar racing. No-one gives a toss about economy, fans watch this series for the sound of V8s and competitiveness of our local racing heroes.

    • Phil

      the idea of CoTF was to reduce costs. Categories that downsize engines and allow things like DRS aren’t saving costs, they’re adding to them compared to unstressed large capacity engines.

      I still reckon sports sedans is the premier category – more flexible rules, up to 6L engines, much lighter, much faster. More exciting. And the flexibility in the rules helps contain costs.

    • horsie

      If you don’t like it, start your own racing category and leave the fans to watch what they want to see V8′s

  • Dan

    Can anyone say Taurus SHO….

    • pro346

      im surprised anyone remembers that thing

  • alan
