So here's the 7 different engines you can choose, I'm sorry I don't explain it any further, but that would take me a couple of hours, and It's getting late here. I can probably do It tomorrow If you wanna know anything about one of the specific engines.
Weight of the S80 is from 2000 kiloes to 2200 kiloes.
Volvo got alot of safety in this car, the most remarkable is the new Driver Alert Control (DAC)
This system will warn the driver if he/she is getting tired, at speed above 65 km/h.
The thing about this Is, that It'll check you're driving routine, and If It doesn't match.. BIPP BIPP.. Take a break.
One of the most remarkable safety systems In this car is the... Intelligent Driver Information System.
I don't feel like writing a boring page about It, but If you wanna read about some amazing safety system, you should defiantly take a look at that.
