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.

Jaguar turns down offers to join V8 Supercars, questions AMG, Volvo participation

Rumors have swirled in recent weeks that Jaguar may be the next manufacturer to join the V8 Supercars racing series, made popular in Australia but now well-known in other parts of the world as well. Sadly, Jag's participation is not to be. In fact, it would be "insane," according to Jaguar Land Rover Asia Pacific Managing Director David Blackhall, for it to accept either of the two offers it has received to bring Jaguar into V8 Supercars.
Not only is Jaguar not interested in entering V8 Supercars, says Blackhall, it also fails to understand the recent entries from AMG and Volvo. "I don't know what it does for AMG to get flogged by a V8 Commodore week after week, but it's their brand, their issue. And the same thing will happen to Volvo to be honest."
Judging by Blackhall's statements to motoring.com.au, after not-so-serious consideration, the automaker decided the monetary commitment it would take to compete for wins would be more than any potential exposure would be worth, despite the fact that Jaguar has a 5.0-liter V8 to go along with what would seem to be a tailor-made rear-wheel-drive chassis. For what it's worth, one offer would have had Jaguar putting its name across an engine made by someone else, an option that was flatly turned down.
