I personally think the 1992 engine was mis-rated at 268hp, but that's a whole separate argument. Note that the identical 119.975 engine in the 1992 S-class was rated at 282hp. And, some of the factory service docs (click here) also indicate that the 119.975 was rated at 282hp, not 262, in both 124 and 140 chassis. 93-up are all rated 275hp regardless of chassis. I think MB was playing a numbers game. The only place that 262hp number appears is in the USA sales literature.
