2015 Volvo S60 T6 Drive-E [w/video]

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.

Volvo debuts new Drive-E four-cylinder engines

Volvo is introducing a new engine family based on its new Drive-E philosophy, which encompasses "all innovations made to reduce the impact on the environment," the automaker says. Less cylinders allows for less environmental impact, so the new engines are all four-pots. They also were designed to pair easily with Volvo's upcoming hybrid drive system, which "will reach power figures in the V8 territory" and play a "dominant part of the top end of [Volvo's] range," says Derek Crabb, Vice President Powertrain Engineering. Volvo also says we can expect "power curves that give exciting drivability compared with engines with more cylinders."
Volvo says some versions of the engine were designed targeting best-in-class fuel economy. There are both gasoline and diesel options, but the latter of which isn't scheduled for US consumption. Instead, the US will be offered two states of tune of the gasoline Drive-E engine for front-wheel-drive vehicles. Some of Volvo's current all-wheel-drive powertrains will remain available in the US until the company has transitioned solely to the new, fuel-efficient inline-fours.

Volvo demos autonomous self-parking car concept

A number of companies are developing autonomous vehicle technology - Google and Audi come to mind - but Volvo is applying its work in the area to a particular usage case: parking. The Swedish automaker has the technology up and running in a concept vehicle, which it says can be dropped off at the curb by its owner and left to its own devices to enter and navigate a car park, then find and park in an available parking spot. Volvo says the process can even be reversed when the owner is ready to go, with the car leaving the car park on its own to meet its key-holder again at the curb.
The vehicle first interacts with Vehicle 2 Infrastructure technology, which places transmitters in the road itself to inform the car (and driver) if the self-parking service is available. The driver then hops out, activates the Self Parking function on his or her smartphone and then leaves the car to do its work. The car uses sensors, all seemingly hidden from view (an advancement of its own in this field), to autonomously navigate the car park, which includes interacting and adjusting to other cars, people and objects.
The technology used here builds off of Volvo's other work in autonomous vehicle research, namely the Safe Road Trains for the Environment (SARTRE) project in which the company managed to create a train of four cars autonomously following a lead truck at speeds up 56 miles per hour. Volvo says the first application of its autonomous research in a production vehicle will happen at the end of 2014 with some level of autonomous steering available in the next-generation XC90.
