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 demos autonomous self-parking car concept

A number of companies are developing autonomous vehicle technology - Google and Audi come to mind - but Volvo is applying its work in the area to a particular usage case: parking. The Swedish automaker has the technology up and running in a concept vehicle, which it says can be dropped off at the curb by its owner and left to its own devices to enter and navigate a car park, then find and park in an available parking spot. Volvo says the process can even be reversed when the owner is ready to go, with the car leaving the car park on its own to meet its key-holder again at the curb.
The vehicle first interacts with Vehicle 2 Infrastructure technology, which places transmitters in the road itself to inform the car (and driver) if the self-parking service is available. The driver then hops out, activates the Self Parking function on his or her smartphone and then leaves the car to do its work. The car uses sensors, all seemingly hidden from view (an advancement of its own in this field), to autonomously navigate the car park, which includes interacting and adjusting to other cars, people and objects.
The technology used here builds off of Volvo's other work in autonomous vehicle research, namely the Safe Road Trains for the Environment (SARTRE) project in which the company managed to create a train of four cars autonomously following a lead truck at speeds up 56 miles per hour. Volvo says the first application of its autonomous research in a production vehicle will happen at the end of 2014 with some level of autonomous steering available in the next-generation XC90.

Volvo S60 Polestar Concept looking Smurfy in Jay Leno's Garage

Is it just us, or has Jay Leno's Garage evolved from an intimate, off-the-cuff video series designed to show off the late-night comedian's automobile collection into something a lot more ambitious and... mainstream? This isn't a complaint, exactly, as Leno has been putting out engaging videos at an increasingly furious pace. However, we can't help but note that the subjects have largely graduated from the funnyman's steam-powered eccentricities and forgotten classics to lots of new production and concept cars, often with automaker execs in tow. It's almost as if the series is turning into an internet version of his NBC talk show, one where bigwigs swing by to show off their latest projects as part of their publicity tours, only instead of new movies and albums, it's cars or the occasional motorcycle.
Such is the exactly case with Volvo's stonking S60 Polestar Concept, which makes its appearance in Jay's warehouse of wonders this week. Tuned by in-house skunkworks Polestar, the "Swedish Racing Blue" S60 has certainly been making the rounds as of late, with recent appearances near Leno's garage at the LA Auto Show and an Auto Motor und Sport track faceoff against the BMW M3 and Audi RS4 Avant.
Perhaps we shouldn't be surprised that Volvo is so keen to get its showcar in front of the cameras - last we heard, executives were seriously considering a small production run for their unlikely 508-horsepower, all-wheel drive sport sedan, though we continue to hear that realistic pricing is likely to be a roadblock.
