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 shows inflatable child seat concept [w/video]

Volvo is bringing its emphasis on safety and design to the littlest members of the family with its concept for an inflatable, rearward facing child safety seat. The design is meant to help traveling families by offering a lighter and less bulky alternative to traditional car seats.
The design is quite ingenious. The seat is covered in drop-stitched fabric, which fills with air to create the form of the seat. An electric motor in it allows inflation and deflation in less than 40 seconds, according to Volvo. It weighs less than 5 kilograms (11 pounds) and folds small enough when collapsed to fit into a bag. It even has a Bluetooth connection, so parents can begin expanding it remotely.
The inflatable seat in the brainchild of Lawrence Abele, Volvo's design manager at its Monitoring and Concept Center in Los Angeles, CA. "For many, travelling with young children is a challenge; any assistance to simplify the parents' life with young children is a great thing," he said in a statement released by Volvo. The chair remains a concept for now, and the automaker isn't saying whether it's going to put it into production, but it's a clever solution to a common problem. Scroll down for a video showing it in action and to read the release.

Volvo recommits to Sweden with development of next-gen platform and engines

Taking into account the facts that Volvo is now owned by China's Geely and how poorly the European automotive market has been recently, we would have definitely understood if Volvo moved production of its products out of its home market. And yet, the automaker has confirmed that it will be investing billions of dollars into new platforms and engines that will be made in Sweden. On a global scale, Volvo is making roughly $11 billion of investments, and close to half of that is being earmarked for Sweden for plant expansion and upgrades.
The new Scalable Product Architecture (SPA) platform will be the used as the basis for most future Volvo products starting with the next-generation XC90 that will be debuting at the end of 2014. SPA will be used to make up two-thirds of Volvo's sales, and gives Volvo a quicker and easier break from Ford-derived platforms. As for the Volvo Engine Architecture (VEA) family of engines, there are really no details about this mill except that it will be a four-cylinder that is more fuel efficient than current engines.
