Boy, 124s certainly rule the mpg criteria. I got near 37 on the way home from picking it up. ( D2 mpg was always 10-15% higher).

It must be a lighter car is all I can reckon.

Several forum members have reported excellent fuel economy with the 606 engine in the '95 W124 chassis. Weight, weight distribution, gearing, smog stuff, etc., may all play a part. The large fuel tank really helped the range; I have read here that Mercedes advertised a 750-mile range for the '95 E300D.

Be careful with your terminology: your '95 had a 606 engine while the earlier 124 models had a 603 or a 602 (both turbo in the USA, other parts of the world could get an NA version). The 4-valve head of the 606 engine should breathe better than the 2-valve 602/603. W210 cars (1996-1999) had 606 engines, NA for 96-7 and turbo intercooled in 98-9. The latter should be the most efficient.
