Actually, 2004... the deadline for a change for 2003 passed on March 15. Toyota has agreed to the current formula through 2003 at the behest of Ford and Honda. . CART's eventual formula will probably displace less that 3.5 litres but the bore limit deck height and V- angle will be the same as the IRL to keep the basic block design workable for both series. There will be no rev-limiter as in the IRL. Honda hasn't agreed to this plan, but more importantly, they haven't said no.... Look for an announcement on engine rules at Detroit.
