Volvo developing new three-cylinder engine family

Pop the hood on a Volvo of recent vintage and you'll find four-, five-, six- and even eight-cylinder engines. But the Swedish automaker is downsizing its engines over the coming years. The new XC90, set to be revealed later this week, will use a new family of four-cylinder engines (like the one pictured above). But that's not even the end of it as emerging reports speak of a new three-cylinder engine family in the works.
The new 1.5-liter turbocharged three-cylinder engine will, according to reports, help Volvo further cut its carbon emissions in line with constricting regulations in markets like Europe and Australia. There won't be quite as many versions as the four-cylinder range, which will include gasoline and diesel versions in varying states of tune, but the three-pot motor is tipped to be employed in vehicles as large as the S60 and its stablemates. Larger than that, however, and the three-cylinder engine apparently just doesn't have the necessary torque.
Expect the new three-cylinder engine to be introduced sometime later this decade, after the four-cylinder's introduction in 2016. The three-cylinder engine is also set to form the building block of an even more efficient hybrid propulsion system in the future, enabling this new engine family to stay relevant through 2025.

Volvo XC90 R-Design adds a dash of sport

The 2015 Volvo XC90 is a huge leap forward for the Swedish automaker as its first all-new model since leaving Ford ownership. There's a lot riding on the crossover's success, too, because its platform is supposed to underpin Volvo vehicles for years to come. The latest move for the new CUV is adding a little aggressiveness to the look with the R-Design trim for buyers desiring a sportier-looking Swede.
The R-Design joins the already announced Momentum and Inscription trims. Mechanically it doesn't change anything, but ticking the box for the R-Design adds a slightly different grille with horizontal slats, a redesigned lower air dam, new window trim, matte silver side-mirror covers and rectangular exhaust nestled in an altered lower rear bumper. The sportier XC90 comes standard with 20-inch wheels, but a 22-inch design is optional, as well.
The meaner look is carried inside with sport seats covered in Nubuck and Nappa leather, a perforated leather steering wheel and R-Design trim for the gearshift, pedals, floor mats and illuminated tread plates. The touchscreen infotainment system also gets an R-Design theme.

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.
