The T8 offers an electric-only range of 44 miles and its 14.7kWh (total) battery can be fully charged in around three hours on an AC connection.
The two mild hybrids use a four-cylinder turbo petrol engine mated to an integrated starter-generator. tThe entry-level B5 makes 247bhp, while an e-supercharger lifts the B6 to 296bhp.
Volvo said that it has reworked the MHEV engines to use the Miller combustion cycle to optimise their fuel efficiency. The B5 has official fuel economy of 33.2mpg and the B6 of 31.7mpg.
Extra sound insulation has been added to the XC90 to make its ride quieter, while Volvo has also revised the standard suspension, with a new double-wishbone arrangement up front, an integral link at the rear and frequency-selective damping.
Volvo claims the new arrangement improves ride comfort and boosts stability. Electronically controlled air suspension will remain an option, using a system that scans the road 500 times per second.
The exterior of the XC90 has been restyled to bring it more closely in line with the EX90 and other recent Volvo models. That includes a revised engine grille, ‘Thor’s hammer’ headlights, new wheels (sizes range from 20 to 22in) and revised rear lights.
