If you liked Motorstorm, you might like Pure. It's not quite the same kind of game but it's an arcadish game focusing on speed. Grid might also be up your alley. Just test the demos.
I'd also suggest Sonic Unleashed if it weren't for the shitty night levels that take like three fourths of the game and suck royally. Such a shame how much that game sucks. The potential is there.
