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 confirms return of the wagon with V60 headed to US

Turns out that promised new production Volvo model for the United States is indeed the V60 wagon, as we had previously predicted. And it's not terribly surprising, as Volvo has a long and storied history of wagon sales in the US, from the old, loveable 240 to the more recent high-performance V70R. And yet the automaker hasn't had a proper non-XC, non-crossover-style wagon in the US since it pulled the V70 away at the end of the 2010 model year.
"The new Volvo V60 is for people who want the handling of a dynamic sports sedan but need the versatility of a wagon," says Volvo, highlighting the reason many of us on the Autoblog team harbor such fondness for wagons in general.
Volvo is currently showing off the R-Design package for its entire model line, including the V60, at the New York Auto Show. We don't know for sure if the V60 will launch with the R-Design package or if it will come at a later date, and we also see no mention of a Polestar edition, though we're hopeful.

Volvo's pedestrian airbags may already be on their way out

As proof of just how quickly automotive technology can advance, just check out the Volvo V40. Developed with an external airbag aimed at better protecting pedestrians in the event of a collision, this innovative safety device could be phased out soon in place of more advanced active safety technologies like pedestrian detection and auto braking.
Go Auto had a chance to talk to Volvo senior VP Lex Kerssmakers at the Tokyo Motor Show, and he suggested that the V40's under-hood airbag will not be used on the next-gen XC90 and might not even be continued on non-SUV models. The passive airbag was designed to deploy at speeds of less than 31 miles per hour to help limit head injuries to pedestrians, but new active technologies are designed to prevent collisions in the first place.
The interview also reveals some details about the new XC90, such as the inclusion of a plug-in hybrid system and the debut of a new safety technology. Kerssmakers told Go Auto that a new Volvo concept will be unveiled at the Detroit Auto Show in January, but it won't be for the XC90.
