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.

They may not be the first thing that comes to mind when you think of the marque, but Volvo has a long and surprisingly lustrous lineage of coupes in its stable, from the P1800 to the 142 to the Bertone 262C to the 780 Bertone and the recently departed C70. Few of those two-doors have stood the test of time the way the voluptuous P1800 has, a fact the company's designers are apparently keenly aware of. It is that exact model that Volvo says they've drawn upon for this new Concept Coupe, and while the showcar bears little resemblance to the smaller P1800 that inspired it, both cars have a visual grace and presence that has often eluded the brand's grasp.
While not completely ripping up the design language established by the 2001 S60 in 2000, the Coupe Concept is arguably the most radical design statement we've seen from Volvo in well over a decade. Gone is the tone set by the drop-shoulder hood, and in its place is a more flowing, organic look, with the generous proportions of a grand tourer. The concept is a particularly nice piece of work, from its new T-shaped daytime running lamps to its pronounced rear fenders that subtly echo those of the P1800. Interestingly, Volvo informs that the first production model to benefit from this new aesthetic will be the next-generation XC90 crossover - and judging by the teasers we recently saw, this language looks like it'll translate nicely to the CUV's larger shape.
The Concept Coupe is powered by a through-the-road plug-in hybrid architecture composed of a twincharged 2.0-liter four-cylinder powering the front wheels and an electric motor servicing the rears. All-in, Volvo says the system is good for 400 horsepower and 443 pound-feet of torque.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.
