Why does my car get 50 MPG and most don't?tivoKlr writes "I drive a 2003 VW Jetta TDI, which averages 40-50 MPG on diesel fuel. I own 2 other vehicles, none of which can touch 20 MPG, and ironically, neither one is as fast or powerful (tourque) as the 50 MPG Jetta.
I don't understand why my car is so efficient when not mandatated to be so by the DOT or NHSTA or whatever federal organization (besides congress) mandates mileage requirements for vehicles?
I could understand if this was a tiny micro-car or something, but I consider a Jetta to be a reasonably sized car, capable of hauling 4 adults comfortably, or 2 adults with 2 child seats in the back (my scenario).
How is it possible that I bought a car that seems futuristic when it comes to fuel consumption and power when everything else around me gets half the MPG that the Jetta is able to provide? Given the current geopolitical situation and our (American) dependence on foreign oil, wouldn't it make sense if all mid-sized sedans got 40-50 MPG?
If someone can explain this to me, pro's and con's (I'm sure my emissions are not as clean as some hybrids) I'd be grateful."
