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 off 345-hp S60 and V60 Polestar

We showed you the hot, new Volvo V60 Polestar a few months back and raved about the fact that this long-roofed family car can hit 60 miles per hour in just 4.9 seconds. Now, we're seeing it and its four-doored brother, the S60 Polestar sedan, in person for the first time.
As we told you when the V60 Polestar was unveiled, both cars are motivated by a 3.0-liter, turbocharged six-cylinder that generates 345 horsepower and 369 pound-feet of torque, with peak twist arriving between 2,800 and 4,750. Power is channeled to a rear-biased all-wheel-drive system via a six-speed automatic transmission with paddle shifters and launch control.
Both Polestar models benefit from a suspension that features Öhlins shocks, while they ride on 20-inch "bespoke" wheels. Six-cylinder Brembo calipers clamp down on 14.6-inch rotors in front, meaning these Volvos should come to a stop as quickly as they get going.

Volvo Concept Coupe may see limited production

Despite the impressive production debuts from Porsche and BMW at this year's Frankfurt Motor Show - the 918 Spyder and the i8, respectively - there was one car that captured the attention of the press and the public alike, enough so that we awarded it our overall top pick of the show: the Volvo Concept Coupe. Most concepts never make it to production, but the car's reception has been so positive that Volvo's board of directors is considering to produce it in limited quantities, Auto Bild reports. Italian coachbuilder Bertone could handle the limited production run.
Styled after the classic P1800, the Volvo concept was similar to the new Porsche and BMW in that it was equipped with a high-performance hybrid drivetrain. But Volvo took a different route from there, giving the sleek coupe a turbocharged and supercharged 2.0-liter four-cylinder engine paired with an electric motor at the rear axle. All in, the combo is good for 400 horsepower and 490 pound-feet of torque.
If the Concept Coupe makes it to production, it may not get the trick hybrid drivetrain mentioned above, Motor Athority reports, but a milder plug-in hybrid setup or even just a conventional fuel-burning engine. In any case, it would be a treat if Volvo produced a fully functional, street-legal Concept Coupe, though at that point we're thinking it would be due for a name change.
