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 to test 100 self-driving cars on Swedish roads [w/video]

Autonomous vehicles are increasingly being tested on public roads around the globe, including Nissan in Japan and Google here in the US, and now Volvo is preparing to test its own self-driving cars on the streets of Sweden. In conjunction with the state government, Volvo's Drive Me project kicks off next year, starting with the development of customer research and infrastructure technology before setting 100 self-driving cars loose on the streets of Gothenburg in 2017.
These 100 cars will be in the hands of customers, and the tests will help Volvo and the Swedish government track varying aspects of self-driving cars including economic benefits, consumer confidence, traffic flow and passenger safety. The technology being developed by Volvo uses not only on-board radar and sensors but also map data gathered from the cloud, and it controls all driving systems including the brakes, throttle and steering. Drivers can engage and disengage the car's autonomous drive mode by pushing a button on the steering wheel, and the technology will also allow for a self-parking feature.
While the cars shown in this demo are S60 models, the test vehicles will be based on Volvo's upcoming Scalable Product Architecture (SPA), which underpins future models like the next-gen Volvo XC90. Scroll down for a video and press release marking the announcement.

Volvo Polestar reveals new V8 Supercars engine

Volvo may be better known for turbo fives and inline fours, but in 2005 it launched the XC90 with a new eight-cylinder engine built for it by Yamaha. Fast forward to this past June when Volvo announced its intention to enter Australia's V8 Supercars series, where it would compete with the likes of Ford, Holden, Nissan and Mercedes-AMG. This is the engine with which it intends to do so.
Revealed this weekend at the Sydney 500, this competition-spec powerplant is based on the same B8444S that powered the XC90 and S80 (not to mention the Noble M600), but tuned for racing duty to be shoehorned into the new S60 touring car. The 60-degree aluminum block has been bored out from 4.4 liters to 5.0, its compression ratio boosted to 10:1, modified to run on E85 bio-ethanol and its redline increased to 7500 rpm. Volvo also promises a unique engine note from its new racers.
While Volvo and its racing partner Polestar haven't released official output numbers, regulations call for outputs between 620 and 650 horsepower - in any event, a whole lot more than the 311 hp it produces in stock form. (Noble managed to squeeze that much out of the same block, but that required twin turbochargers while this unit remains naturally aspirated.) Scope out the details in the press release below and the photos from the reveal in the gallery above.
