From an evolution to a revolution

Audi claimed that the R10 was an evolutionary change to the successful R8. The R15 to be raced privately in 2009 is considered revolutionary. I had been thinking for some time with the addition of winglets and ancillary body structure was terminal. The current crop of F1 cars also seem to have gone through considerable revolutionarty chane, rules driven or not, I think it was necessary. Sebring in March will be the first tet for the R15. Audi seems to have a pretty successful formula. Odds are good for them to show the rest of the motor racing world, again. Many thanks to ultimatecarpage.com and autoblog.com.
