Car appreciation... the aesthetics, the engineering, etc

I think i must have underestimated the power of that 4 cylinder Volvo if it's running in the 6.8's, what power would you need for that?

that rx3 is a steel bodied car with glass, i think prob 1400kg or 3000lb.

i'd hazard a guess that the volvo would be minimum 1600 fwhp, but much lighter car.
