The previous-generation S80 was powered by a turbo six as well, but the latest engine uses a single, twin-scroll turbo as opposed to the previous car’s 2.9-liter twin-turbo setup, which produced 272 hp.
The new turbo motor has been downsized in displacement from the 3.2-liter I-6 by decreasing both bore and stroke, but it’s nevertheless good for 285 hp and 295 lb-ft of torque, increases of 50 hp and 56 lb-ft over the regular six-holer. The S80’s V-8 makes 311 hp and 325 lb-ft of torque.
Maximum twist is on tap from just 1500 rpm. The S80 T6 (V-8 AWD model pictured above and in photo gallery) will be exclusively all-wheel drive—"for now," says Volvo—when it goes on sale sometime this fall.
