2011 Volkswagen Jetta TDI: Strong First Half

Yes, the trip odometer had been reset properly when our 2011 Volkswagen Jetta TDI was last filled with diesel fuel. This appears to have been a very strong half-tank performance, but the lesser figure on the miles-to-go readout suggests that maybe this gauge isn't accurately predicting the halfway point.

I pulled up to a pump and refilled the tank to sort it all out.

The Jetta took on 9.551 gallons out of a possible 14.5, so by rights the fuel gauge should be at the one-third point. Still, this tank of mixed driving -- a bit more freeway than city, perhaps -- works out to 38 mpg. The Jetta's EPA combined rating is 34 mpg.

Overall performance after 17,100 miles goes like this:

Average lifetime fuel economy: 35.3 mpg (better than EPA-rated)

Best fuel economy: 46.1 mpg

Best single tank range: 642.7 miles

Average range: 357.7 miles on an average fillup of 10.1 gallons

This car can easily top 400 miles per tank if you allow the needle to get past the one-quarter mark. The tank pictured above already exceeds the average and still registers half full. Heck, it's still be impressive if it accurately read one-third full.

Remember that we're stopping at the pump less often than once per week, on average, even though we're driving at a an elevated pace intended to achieve 20,000 miles per year. Drive 12,000 miles per year and you may only need to stop twice a month.

The best part is this: this thing is no slug off the line. We're not hypermiling the Jetta to get these numbers. Diesel torque rules.
