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 planning Golf rival, 'breathtaking' C60 coupe

Despite just having refreshed nearly its entire portfolio, Volvo is still in the middle of a big product offensive. Vehicles like the C30 hatchback and C70 convertible have been given the axe, but a brand-new platform is being developed in addition to the Scalable Platform Architecture (SPA) that will underpin larger vehicles. According to Automobile, this means some very interesting newcomers may be on tap for the brand.
Volvo, in collaboration with Geely, is said to be working on a new platform about the size of a Volkswagen Golf that will likely spawn both a sedan and hatchback. Automobile reports that while the automaker's new scalable architecture is quite flexible, it cannot be stretched (or rather, shrunk) to accommodate a smaller vehicle.
Instead, SPA will be used for the company's larger offerings, starting with the V40 on the small end. (Though to our eyes, the current V40 looks plenty Golf-sized to us.) A new XC40 is apparently in the works, as is an S90 flagship, and new versions of the XC60, XC90 and S60 will all be coming based on this new flexible architecture.

2015.5 Volvo S60 and V60 Polestar [w/video]

Polestar Performance has been around since 1996, but until recently, it only did two things: manage Volvo motorsports operations and run a specialist consumer-facing side that built concept cars and boosted Volvo's turbocharged production cars by 15 to 60 horsepower. Five years ago, it fulfilled its long-held desire to engineer an actual production car, first creating the C30 Polestar Performance Concept, a showcar that led to the C30 Polestar Limited Edition.
That foray led to the berserker, 508-horsepower 2013 S60 Polestar Concept that Auto Motor und Sport called "a hard slap in the face to the Germans," and that model led to the limited-edition S60 Polestar production car just for Australia, a car reviewers swooned for, with one comparing its chassis finesse to the Ferrari 458 Italia.
All of which is to say, Polestar has a good start for a motorsports and tuning company to make good on its production car dreams. The 2015 Volvo S60 Polestar and V60 Polestar keep that momentum going, and beautifully at that.
