The 190D changed from the 2.2l to the 2.5l engine (602) about '86 (don't know the year for sure). A much peppier engine even without the turbo.

The 190D 2.5 (non-turbo) is listed at 2845lbs in '87, the turbo at 3010lbs, the 300D turbo at 3375lbs. Big difference in final-drive ratio with the non-turbo (3.42:1) vs the turbo cars' 2.65:1 to help it launch.

The 240D was 2.4l, I don't think that changed even in the US. I'm not really confident that the 240D was lighter than the 190D, could have been. Although the 240D might have been built with heavier body steel etc., it had less features and creature comforts than the later 190Ds which add weight (such as sound-deadening and airbags for example).
