Yes Thi, you're almost right, just a little bit off,
When the '745' was introduced the enginesize was 3210cc(* 1.4 = 4.5)
but soon the engine was swapped for the 3430cc(* 1.4 = 4.8!) BMW did
not rename the car, they stuck to 745. If you look up the official
racing
rules you will see that turbo-engines are now rated at 1.7 times the
non-aspirated
engines. So... now the 745, which really is a 748 should be a 758!!!!!!!
