The S80 is Volvo's largest sedan, but not by much. Compared to other vehicles in the luxury segment, the S80 is actually smaller than midsized offerings like the BMW 5-Series and Audi A6. The base S80 is offered with a 3.2l six-cylinder engine and front-wheel-drive. The higher priced T6 model equips a more powerful turbocharged six-cylinder engine and all-wheel-drive. The S80 has a healthy list of standard equipment.
