Volvo Polestar reveals new V8 Supercars engine

Volvo may be better known for turbo fives and inline fours, but in 2005 it launched the XC90 with a new eight-cylinder engine built for it by Yamaha. Fast forward to this past June when Volvo announced its intention to enter Australia's V8 Supercars series, where it would compete with the likes of Ford, Holden, Nissan and Mercedes-AMG. This is the engine with which it intends to do so.
Revealed this weekend at the Sydney 500, this competition-spec powerplant is based on the same B8444S that powered the XC90 and S80 (not to mention the Noble M600), but tuned for racing duty to be shoehorned into the new S60 touring car. The 60-degree aluminum block has been bored out from 4.4 liters to 5.0, its compression ratio boosted to 10:1, modified to run on E85 bio-ethanol and its redline increased to 7500 rpm. Volvo also promises a unique engine note from its new racers.
While Volvo and its racing partner Polestar haven't released official output numbers, regulations call for outputs between 620 and 650 horsepower - in any event, a whole lot more than the 311 hp it produces in stock form. (Noble managed to squeeze that much out of the same block, but that required twin turbochargers while this unit remains naturally aspirated.) Scope out the details in the press release below and the photos from the reveal in the gallery above.

Volvo celebrates 20 years of sleeper wagons with 850 T-5R and V60 Polestar

I must have been around Bar Mitzvah age when I was in the back of my parents' car on the highway as we passed a truck full of Volvo 850 T-5R wagons - half of them in black, half in banana yellow. It was one of the coolest things I'd ever seen: a whole gaggle of sleeper power wagons that were infinitely cooler than whatever minivan we were riding in. Hard to believe that was 20 years ago, but it was. And Polestar is understandably keen to mark the anniversary of the first overt Volvo performance wagon.
While Volvo's racing partner hasn't released some commemorative edition to celebrate that prototypical sleeper, it has shot a special batch of photos of the T-5R (based on the 850 wagon internally known as the 855 for its five doors) alongside its modern successor, the V60 Polestar. The images shot in Huntington Beach, CA, only go to show how much has changed in the two decades that separate them.
Whereas this front-drive T-5R packed a turbocharged inline-five driving 240 horsepower through a four-speed automatic propel the yellow box to 62 in 7.0 seconds, the turbo six in the svelter, Rebel Blue-clad 2015 V60 Polestar churns out 350 hp to all four wheels through a six-speed auto for a 4.9-second sprint. That's the kind of progress we can get behind. In fact, it's the sort of progress that everyone can get behind, really, because chances are whatever you're driving will probably have a hard time keeping up.

Volvo C30 Polestar Concept hits the 'Ring

It's been over three years since the Volvo C30 Polestar Concept was unveiled, driven by journalists and, as it turns out, lapped around the Nürburgring with Scandinavian Touring Car Championship driver Robert Dahlgren behind the wheel. For whatever reason, the video of the 'Ring track session was only published by the tuning company yesterday. (Another discrepancy: Did Polestar's C30 lose 46 horsepower somewhere along the line? Because the video states that it has 405 hp, while the company's website quotes 451 hp...)
Whatever the case, the tuned Volvo is a beast, much more so than the similar-looking, 250-hp 2013 Volvo C30 Polestar Limited Edition that was sold last year. With 451 hp (sounds better than 405 hp, doesn't it?), all-wheel drive, limited-slip differentials front and rear and Öhlins dampers, the Polestar Concept checks all of the right boxes for us.
For some reason, the video, which you can watch below, seems a bit vanilla to us. Perhaps the overly dramatic music takes away from the action and the beautiful sounds of the turbocharged five-cylinder engine?
