Fuel Economy of the 1985 Chevrolet Caprice Wagon

The total weight must've been close to 7000 lbs. The TDI (stock other than nozzles) pulled the weight just fine. Hills were a bit slow. With the reduction in drivetrain weight, the Caprice/Roadmaster won't weight much more than a Jetta or Passat.

Other options are the Cummins 4BT and Mercedes OM617a.

Thanks. I think I'll go with something powered higher though. And I didn't mention it in the topic but I am playing with the thought of using the car as a towing vehicle too.

I'm talking about a 1996 model although I didn't specify that in the topic at first. Are there specs here relating to the ratio? (Also, I'd like something at least the size of a 5.0.)
