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 XC90 R-Design adds a dash of sport

The 2015 Volvo XC90 is a huge leap forward for the Swedish automaker as its first all-new model since leaving Ford ownership. There's a lot riding on the crossover's success, too, because its platform is supposed to underpin Volvo vehicles for years to come. The latest move for the new CUV is adding a little aggressiveness to the look with the R-Design trim for buyers desiring a sportier-looking Swede.
The R-Design joins the already announced Momentum and Inscription trims. Mechanically it doesn't change anything, but ticking the box for the R-Design adds a slightly different grille with horizontal slats, a redesigned lower air dam, new window trim, matte silver side-mirror covers and rectangular exhaust nestled in an altered lower rear bumper. The sportier XC90 comes standard with 20-inch wheels, but a 22-inch design is optional, as well.
The meaner look is carried inside with sport seats covered in Nubuck and Nappa leather, a perforated leather steering wheel and R-Design trim for the gearshift, pedals, floor mats and illuminated tread plates. The touchscreen infotainment system also gets an R-Design theme.

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?
