Split/Second has "choppers". Blur has careers and power-ups. The tutorial movies after the break prove it.
In summary: Career involves getting Lights and Fans to unlock event and new cars. Complete rivals' demands to try to beat them, after which you steal their cars.
Power-ups are power-ups. You drive through them and fire them.
Blur's a racing combat game from Bizarre Creations. It's out for PC, 360 and PS3 on May 28. OK? Good. Watch the movies.
