The second-generation Volvo S80 saloon was first introduced for sale back in 2006 and hasn’t seen many major alterations since then except for the introduction of a long-wheelbase version for the Chinese market late last year. That’s all set to change as Volvo has announced plans for a slightly refreshed version due to go on sale in the coming months.

Updates to the car, which arrives in time for the 2010 model year, include distinctive changes to the body, a more exclusive interior and a sharper chassis and upgraded engine range. The new model looks lower, longer and wider. This is thanks in part to a new grille and rocker panels.

Inside, designers have focused on improving the premium feel of the car. New leather seats are featured, and are accompanied by door panels echoing the same trim. The car’s floating center stack has also been upgraded with a silk metal frame that matches the more modern units found in newer models like the XC60.

New to the engine range is the introduction of a brand new five-cylinder diesel unit. The new engine is Euro 5 compliant and delivers up to 205hp (152kW) and 310lb-ft (420Nm) of torque - all while returning fuel economy of 38mpg (6.2L/100km) and C02 emissions of roughly 164g/km. The 2010 S80 is also available with a second diesel, rated at 175hp (130kW) and 310lb-ft (420Nm) of torque.

Finally, Volvo has also added a new chassis management system with two different settings. A “comfort” chassis will be offered as standard and a lowered “sport” chassis will be offered as an option. This sport version features a 20mm lower ride height up front and a 15mm lower height at the rear, stiffer springs, improved shock absorbers, and firmer anti-roll bars.

The refreshed Volvo S80 will be unveiled for the very first time at the Geneva Motor Show next week and will go on sale in most markets by the middle of the year.
