Efficiency without compromise: the T8 Twin Engine powertrain from Volvo, launched in the 2016 XC90, represents these traits. Made possible through Volvo’s Drive-E engine (2.0-liter, four cylinder, super- and turbocharged) and Scalable Product Architecture (SPA), the T8 Twin Engine ensures high power with cleaner emissions than many other automotive power plants available today – 400 horsepower, 59MPGe, 20 miles on pure electricity in the XC90. A gasoline engine up front mates to an electric motor at the rear for eAWD, with the two united through an integrated starter generator just past the transmission versus a driveshaft. The generator can also provide an additional power boost in certain situations. With SPA, Volvo can place the Lithium-Ion batteries in the traditional transmission/driveshaft tunnel, resulting in better weight distribution and interior layout. Passengers thus enjoy more seating space, ultimately earning the XC90 T8 Twin Engine the title of the first plug-in hybrid, seven-seat SUV.
