Based on the S60's platform, the career of the XC60 in its current form is winding down, despite it being Volvo's bestselling vehicle. It's also saying farewell to the five- and six-cylinder engines and leaving only the four-cylinder Drive-E with 240 horsepower (T5 turbo) and 302 horsepower (T6, turbo and supercharger). The T5 has standard FWD and optional AWD, the latter being included with the T6. All XC60s are equipped with an eight-speed automatic gearbox.
