Volvo specs new 450-hp triple-charged four-cylinder engine

When Volvo lifted the veil on the new XC90 a little over a month ago, it announced that all versions would be powered by one engine design: a new 2.0-liter four-cylinder to be offered in various states of tune. That would range, Volvo said, all the way up to a high-output version with "around 400 horsepower," but while it wouldn't specify exact output, now it has.
The new High Performance Drive-E Powertrain incorporates two parallel turbochargers fed by a third electric turbo-compressor. Instead of feeding the cylinders directly, that third unit spools up the twin turbochargers, working together with a dual fuel pump pressurized to 250 bar.
The result is an output of 450 horsepower - far more than the existing 320-hp version and even more than expected. That also works out to 225 hp/liter, far more than the 177 hp/liter boasted by Mercedes-AMG's high-output turbo four and the 139 hp/liter in the Alfa Romeo 4C. Short of a rotary engine (whose actual displacement is the subject of great debate), you'd have to go up to something like the Koenigsegg One:1 (268 hp/liter) to find a higher specific output than what Volvo's boasting here.

Volvo S60 Polestar Concept looking Smurfy in Jay Leno's Garage

Is it just us, or has Jay Leno's Garage evolved from an intimate, off-the-cuff video series designed to show off the late-night comedian's automobile collection into something a lot more ambitious and... mainstream? This isn't a complaint, exactly, as Leno has been putting out engaging videos at an increasingly furious pace. However, we can't help but note that the subjects have largely graduated from the funnyman's steam-powered eccentricities and forgotten classics to lots of new production and concept cars, often with automaker execs in tow. It's almost as if the series is turning into an internet version of his NBC talk show, one where bigwigs swing by to show off their latest projects as part of their publicity tours, only instead of new movies and albums, it's cars or the occasional motorcycle.
Such is the exactly case with Volvo's stonking S60 Polestar Concept, which makes its appearance in Jay's warehouse of wonders this week. Tuned by in-house skunkworks Polestar, the "Swedish Racing Blue" S60 has certainly been making the rounds as of late, with recent appearances near Leno's garage at the LA Auto Show and an Auto Motor und Sport track faceoff against the BMW M3 and Audi RS4 Avant.
Perhaps we shouldn't be surprised that Volvo is so keen to get its showcar in front of the cameras - last we heard, executives were seriously considering a small production run for their unlikely 508-horsepower, all-wheel drive sport sedan, though we continue to hear that realistic pricing is likely to be a roadblock.

Volvo Polestar celebrates STCC title with Black R edition S60, V60 and XC60

The relationship between Volvo and Polestar was forged - and forges deeper still - on the racetrack, where the latter fields the former's tin-top entries in the STCC, WTCC and V8 Supercars. And based on their success together in touring-car racing, Volvo has had Polestar amp up a number of its production road cars. What we have here is the latest.
This year Volvo and Polestar dominated the Scandinavian Touring Car Championship, taking both the drivers' and manufacturers' titles. So to celebrate, Polestar has rolled out a new Black R package for the S60 sedan, V60 wagon and XC60 crossover.
The package includes an upgrade to 329 horsepower for the T6 engine and to 230 hp for the D5, and further enhances with special wheels, a dropped suspension, special sport seats and more. Unfortunately the package is only being offered in Sweden, but you can scope out the details in the press release below and the photos in the gallery above.
