look if u are comparing both vehicals for a race
then both cars are compatible but it depends on the driver..........
u can't say cultus efi definately will win against vitz (auto or manual) similarly vitz can beat cultus easily...........
Cultus is however 16 valve, 4 cylinder, G10B (1000cc) engine (mostly like G16B engine of baleno 1.6Gti) where as
Vitz 12 valves, 3 cylinder, vvti engine
Depends on the driver, a car never runs only a driver run...
