Volvo announced today that it has updated its S80 sedan. The 2010 Volvo S80 gets refreshed exterior styling, an upgraded interior and sharper chassis and an updated engine range.

“We are ready to give the competition a tough match. With the new S80, we’re placing the bar at the very highest level when it comes to exclusiveness, quality and driving properties,” says Volvo Cars President and CEO Stephen Odell.

In the U.S., the 2010 Volvo S80 will be offered with a 3.2L inline 6, the turbocharged T6 3.0L inline 6 and the top-of-the-range 311-hp 4.4L aluminum V8. The T6 and V8 models will come with Volvo’s Instant Traction AWD system as standard.

The 2010 S80 will make its world debut at the Geneva Motor Show next week with U.S. sales to start in the second half of 2009. Pricing details will be announced closer to launch.

2010 Volvo S80:

Of course good news like this only comes for the Europeans. Volvo is introducing a new 2.4L 5-cylinder diesel engine for its S80 sedan. The new D5 engine will be available in the UK starting mid-2009 and Volvo will soon release pricing and further specification closer to launch.

What we do know right now is that the engine has sequential twin-turbochargers and piezoelectric fuel injectors that allows it to produce a total of 205-hp with a maximum torque of 310 lb-ft of torque. That allows for a fuel-economy figure of 45.6mpg (38 mpg U.S.) and CO2 emissions of 164g/km.

The new D5 engine is also equipped with ceramic glow-plugs, an innovative solution that allows cold-starting properties via a very quick warm up period.
