I read where the engine is limited to around 172 MPH. Can this be made to go away? If so, what would the car truly do at top end?

 

interested in this too...friends M3 already overspeeded me in top speed..I bumped at 275km/h...

speedometer


naw gps speed

 

It's electronically limited.

Back in the day, some used the Apex'i Rev Speed meter to override the limiter on many Toyota models. Not sure if this still works with the newer Toyota/Lexus/Scion models.

 

how did your friend take you at top speed in the M3. the new ones are supposed to be limited to I think 160 or lower. Im sure it was not as high as the F's 172. I read somewhere that if the lex wasant limited it could hit 190....

 

186mph is the top speed for the IS-F if you take out the limiter...heh but dang...I don't think I'll ever get to 170mph much less 186mph...lol

 

Yeah I'm pretty sure BMW advertises the M3 electronically limited at 155. I've heard of people taking off the limiter though already. I heard it only gives them like 10 more mph.

 

in Europe, u can buy limiter off function with tickets to Nurnburgring for driving lesson.

Also MB amg can take off limiters with some package..
