How do you get 4400 lbs for the weight of your 245?
And yes, I always thought Volvo was conservative with the hp numbers, and the little 4 cylinder is fairly torquey. Then too, a lot of the numbers for output on the rice burners are achieved only at high rpms, and are effectively not usually available. And an intercooled 24X? Not much on the road is faster in the 3000-5500 rpm zone. If you catch them right with your gear selection and speed, you will beat them.
