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 Cars reports theft of R&D data by hackers

STOCKHOLM — Volvo Cars said on Friday it had launched an investigation into a cyber security breach and the theft of some research and development data that could impact the company's operation. A spokesperson for the firm, majority owned by China's Geely Holding, said it had been approached by a third party, but declined to give any further details. "Investigations so far confirm that a limited amount of the company's R&D property has been stolen during the intrusion," the Swedish carmaker said in a statement. It added that "there may be an impact on the company's operation," without specifying what that might be. It said it did not see an impact on the security of its customers' cars or their personal data. The Gothenburg-based company said it had implemented security countermeasures to prevent further access to its property, while notifying relevant authorities. "Volvo Cars is conducting its own investigation and working with a third-party specialist to investigate the property theft," it said. Shares in Volvo Cars, whose IPO on Oct. 29 was the biggest in Europe this year, were down 3.2% at 1555 GMT.  

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.
