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 finds a way to turn body panels into batteries [w/video]

One of the problems with designing an electric vehicle is figuring out where to fit the battery pack. Volvo - as a part of a European Union research project - is working on a way around this issue by replacing standard parts with lightweight components that double as batteries on both conventional and plug-in vehicles. The image above shows one such piece on a Volvo S80. While looking like nothing more than a carbon fiber plenum cover, the piece is actually a battery pack that can store and supply enough energy for the car's entire 12-volt power system.
The parts are made by sandwiching super capacitors (which can charge faster than standard batteries) in between layers of carbon fiber. They can then be formed to replace numerous body panels such as the decklid, roof or door panels. Volvo says that the replacing the body panels and batteries with these nano batteries can help reduce the vehicle's weight by as much as 15 percent. It has taken more than three years just to design the batteries, so there's no telling when, or if, we'll ever see this technology used on a production vehicle.

Volvo won't go after S-Class, 7 Series market

Volvo vice president of powertrain engineering, Derek Crabb, recently said that the Swedish automaker is developing smaller and smarter powertrain options that will "turn V8s into dinosaurs" - a statement that could have been our first indication that Volvo is no longer looking to create a luxury flagship sedan to take on German land yachts like the Mercedes-Benz S-Class, Audi A8 and BMW 7 Series. Now Automotive News seems to be backing this up after speaking with CEO Hakan Samuelsson, who said that a big sedan wouldn't fit the brand's green image and, more importantly, might not even be a car that its customers would even consider.
Rather than trying to compete in a small, established market against rear-drive, 12-cylinder sedans, Volvo is looking at the emerging, higher-volume premium small car segment to take on its German rivals with the all-new Volvo V40 (shown above). Not wanting to abandon the big-vehicle segment altogether, a next-generation XC90 is due out within the next couple years (and was spotted in some recent spy shots), and it will ride on the new Scalable Platform Architecture (SPA), which will be shared with the new S80 according to the AN article.
