2015 Volvo XC90 mule spotted testing in the snow

The Volvo XC90 was a big step for the Swedish automaker in 2003, but the midsize crossover has changed very little since its introduction. All that's about to change as Volvo starts its initial development on the 2015 XC90, which we see for the first time in these spy shots showing a cobbled-together XC70.
Like the current XC90, the next-generation model will be both longer and wider than the XC70 - judging by the modifications made to this mule's body - which will continue to allow Volvo's flagship crossover and provide three rows of seating. The next XC90 will ride on a new platform that will eventually make up around two-thirds of all Volvo sales, called the Scalable Product Architecture (SPA).
Our shooter managed to find out the registration number for this mule, which indicated that it was powered by a five-cylinder diesel, but we expect the automaker to start stepping away from its current powertrains with a big push toward smaller engines courtesy of the new Volvo Engine Architecture (VEA). Rumor has it that the future engine lineup for the XC90 will rely heavily on turbocharged four-cylinder engines and eight-speed automatic transmissions, which will likely eliminate or lessen some of the current mills available like a straight-six or V8.

Volvo promises new direct-injected diesels, 8-speed auto

As a part of eliminating its dependence on Ford platforms and powertrains, Volvo has previously announced information about its Volvo Engine Architecture (VEA) and Scalable Platform Architecture (SPA), but now we're finally getting some details about what will power some of the Swedish automaker's next-generation products.
The biggest key to VEA on the diesel engines is a new technology Volvo calls i-ART. This system uses unique injectors at each cylinder capable of monitoring fuel pressure and adjusting accordingly to maximize fuel economy and performance and reduce emissions. Looking ahead, Volvo says its four-cylinder engines will be able to offer the power of a six-cylinder and eventually, mixed with some sort of electrification, will be able to rival the performance of a V8 and "turn V8s into dinosaurs."
More details about the new diesel injection technology is posted in the press release below.

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.
