2019 Volvo XC60 review - engine, transmission and technical details

Engine, transmission and technical details

As briefly mentioned above, all XC60 models utilise essentially the same 2-litre four-cylinder engine, in petrol and diesel forms. Both share a 1969cc displacement, and depending on their outputs feature a pretty wide spectrum of forced induction methods. Petrol engines are either single-turbocharged or turbo and supercharged, and produce 247bhp and 306bhp in B5 (petrol) and T6 forms. The T6 engine is also used in the T8 Twin-Engine plug-in hybrid variant, with a combined (not equivalent, mind) output of 394bhp, or 399bhp in T8 Polestar Engineered form. Both plug-in hybrid variants use the petrol engine to drive the front axle, with the rear driven exclusively by the 86bhp electric motor on the rear axle.

Diesel variants are somewhat more simple, with the sole D4 model producing 187bhp from a twin-turbocharged version of the diesel engine variant. It’s the mild-hybrid versions that add a new complication to the range, as B4 and B5 (diesel) variants combine a twin-turbocharged diesel with a mild-hybrid system that produce 195bhp and 235bhp respectively.

All engine variants in the XC60 include an eight-speed automatic transmission, operated by either a normal lever, or in some cases, a dubious crystal selector. All-wheel-drive models (bar the T8) utilise a front-wheel-drive-biased system, only sending power to the rear wheels when required.
