It is true that the e12 M535I and e28 M5 are not the same car but both had M engines. Both are adjustments of the m88 from the M1.The M535i and the M5 where not the same car. The M535 was a M5 looking car with all the trim, but not the engine. The prefect wannabee car.
The M5 has a WBS VIN.
The E12 M535i had a 3453cc M30 non-M engine and a WBA Chassis numberIt is true that the e12 M535I and e28 M5 are not the same car but both had M engines. Both are adjustments of the m88 from the M1.
I do not believe the e12 version had the M88 engine. I had the regular euro 12 valve 6 banger. Only the e28 version had the m88 24 valve motor.It is true that the e12 M535I and e28 M5 are not the same car but both had M engines. Both are adjustments of the m88 from the M1.
All correct except the last line:The E12 M535i had a 3453cc M30 non-M engine and a WBA Chassis number

It WAS an M powered engine car. But it was built before Motorsport division built the entire car. Motorsport only built the motors back in the mid 80's. The motor was a direct descendant of the M1 racing motor. The M635 was introduced in 1984 at the Frankfurt Auto show.I think the same with M635. It wasn't a M-power engine car.
The Euro version did have the higher compression, tubular stainless steel headers, and the single row cam chain and cam chain tensioners, more aggressive ECU computer mapping. It had no smog equipment whatsoever, not even EGR. The European market emphasised lighter weight and performance over luxury. The Euro M635 tipped the scales at 3300 lbs (that is what my Euro M635 weighed at the port prior to DOT/EPA cert). Each Euro car was custom specified by its potential buyer before build, and many came equipped only with manual sport seats. These cars also had the water buffalo hide option which was never offered in US cars. I have had no rust on either of the Euro M635s I have owned, but they are CA cars and do not see salt on the roads during winter.Well, the euro M635csi like the Euro M5 had a slightly different engine, 286 vs 256 HP.
Europeans got the better headers and compression, but possibly single thickness timing chain, no?
Also, lighter cars, less weatherproofing, and more likely to rust in the fenders....that's my vague recollection. I had a M6 for a while......nice Luxo cruiser.
