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.

This is Volvo's awesome S60 V8 Supercar entry [w/video]

Australian auto news has been dire for the last several months with all three automakers that build there announcing they would stop production within the next three years. But Volvo is providing a shot of excitement with the unveiling of its new S60 racecar for the upcoming season of the Australian V8 Supercar series.
The Volvo S60 racecar will use a 5.0-liter, naturally aspirated V8 based on Volvo's B8444S production engine that will be tuned to produce roughly 650 horsepower on E85 ethanol. Power will get to the ground via a six-speed sequential transmission, and it will be able to reach 62 miles per hour in 3.2 seconds and a top speed of 185. All cars in the series use common parts for the chassis, transaxle, and rear suspension.
Volvo's Polestar performance arm will campaign two of the S60 racers this season. While Volvo might seem like an odd inclusion into Australian racing, it actually has quite a successful history. It won the 1986 Australian Touring Car Championship in a 240 and won the Bathhurst 1000 race in 1998 in an S40. Polestar is not new to racing either, having been racing Volvos around the world since 1996.

Volvo debuts new Drive-E four-cylinder engines

Volvo is introducing a new engine family based on its new Drive-E philosophy, which encompasses "all innovations made to reduce the impact on the environment," the automaker says. Less cylinders allows for less environmental impact, so the new engines are all four-pots. They also were designed to pair easily with Volvo's upcoming hybrid drive system, which "will reach power figures in the V8 territory" and play a "dominant part of the top end of [Volvo's] range," says Derek Crabb, Vice President Powertrain Engineering. Volvo also says we can expect "power curves that give exciting drivability compared with engines with more cylinders."
Volvo says some versions of the engine were designed targeting best-in-class fuel economy. There are both gasoline and diesel options, but the latter of which isn't scheduled for US consumption. Instead, the US will be offered two states of tune of the gasoline Drive-E engine for front-wheel-drive vehicles. Some of Volvo's current all-wheel-drive powertrains will remain available in the US until the company has transitioned solely to the new, fuel-efficient inline-fours.
