Your Jetta also produces all of 74 horsepower. That wasn’t much in 1997 and it’s even less by today’s standards. The new TDIs are better, but I don’t see the U.S. embracing diesel like Europe has any time soon. I wouldn’t want one. I drove a co-worker’s 2005 TDI Jetta to lunch a while back. I was not impressed. It had good initial grunt. But at 3000-3400 RPM the engine fell flat on its face and was producing far more noise than power. The narrow powerband means you really have to row through the gears to keep the engine in optimum range. I’ll take a gas engine every time.
