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.

The Swedes Bend Sixes And Fives Into Fours
With government agency pressures mounting, the auto industry's latest engine and powertrain trends invariably include the cobbling of heretofore eight-cylinder models into charged (either turbo- or super-) six-cylinder models, six-cylinders into charged four-cylinders and so on. And then there's the mating of these downsized engines to fuel-saving automatic transmissions with ratio counts previously reserved for bicycles and semi trucks. Volvo can at last follow suit with the best of Germany and Japan thanks in great part to an $11-billion multi-year investment by its Chinese owners, Geely.
After we survived the recent Frankfurt Motor Show marathon of news and reveals (chief among said bits being the stunning Volvo Concept Coupe), we were escorted by the Swedish automaker to the far less frenetic air of southern France to explore the most significant step yet in the company's new life. Volvo's entire movement of new tech is referred to as Drive-E, and it includes these all-new four-cylinder engines we just tested, a new modular architecture called Scalable Product Architecture (SPA) that will first be found under the next-generation XC90, along with a host of other onboard advancements. Think of it as a Scandinavia's version of Mazda Skyactiv, a total-systems approach to developing more efficient yet more sporting new models.

California adapts ZEV mandate with PHEVs for smaller automakers

California is the nation's largest market for zero-emissions vehicles with over 100,000 of them estimated to be on the roads there. The state's goal is to keep that number growing every year. To that end, the California Air Resources Board is now tweaking its rules in a way that might not boost ZEVs but could mean more plug-in hybrids for the Golden State. Jaguar Land Rover, Mazda, Mitsubishi, Subaru, and Volvo asked for an exemption to the state's zero-emissions vehicle mandate last year due to their relatively small development budgets compared to larger automakers. CARB denied their request but did craft a compromise, according to Automotive News. Rather than being required to offer a ZEV in the state, companies with an annual global revenue of less than $40 billion, like those in this group, may instead sell plug-in hybrids to earn ZEV credits. The companies aren't completely off the hook, though. If these plug-in hybrids don't earn enough credits, the corporations must buy them on the market to make up the difference. Automakers with popular electric models like Nissan and Tesla have made a big business through this trading system by selling their surplus to rivals. Tesla alone pocketed $51 million in the first quarter from this part of its business, according to Automotive News. The changes to the regulations also aren't set in stone, yet. CARB is meeting in 2016 and could adjust things further at that time.
