2014 Volkswagen Passat TSI: Fuel Economy Update for December

January 3, 2014

2014 Volkswagen Passat TSI

The end of December marked the end of our first month with our 2014 Volkswagen Passat TSI and its fuel-economy-centric 1.8-liter turbocharged four-cylinder. Thanks to fairly impressive range, we've only run through three tanks of fuel over more than 1,200 miles of driving.

What kind of fuel economy is our new gasoline-powered Passat returning and, importantly, how is it comparing to our diesel Passat? Find out below.

Worst Fill MPG: 24.1
Best Fill MPG: 27.6
Average Lifetime MPG: 26.1
EPA MPG Rating: 28 Combined (24 city/34 highway)
Best Range: 451
Current Odometer: 2,280

Now, let's take a look at the Passat TDI's fuel economy from November. Just for kicks.

Worst Fill MPG: 25.2
Best Fill MPG: 43.8
Average Lifetime MPG: 36.7
EPA MPG Rating: 34 Combined (30 city/40 highway)
Best Range: 733.8
Current Odometer: 11,031

    I'm a little dissapointed in that best fill. That's pretty much the same mileage i got from the 1.8T/tiptronic combo in my '04 Jetta. I know the Passat is a bigger car, but it's also got an extra gear and 8 years of improved tech.

    I have just under 1000 miles on my TSI. Love the motor & auto transmission. Way too cold to be taking mpg seriously. -10 is possible this evening. Low 30's mpg is very reachable, just have to get some temps warmer than the teens.

    Crazy. I don't think I have ever gotten less than 26 mpg with my 5-cylinder 5-speed 2012 Passat. Summer highway mileage is 36-38 mpg, winter -- 33-34 mpg. This result is much worse than I would expect. I thought the new engine is supposed to be MORE fuel efficient?!

    @vvk I have found MPG is highly dependent on regional location. Every region in the US uses a different fuel blend based on air pollution, altitude, and weather. I currently drive a 2013 Hyundai Accent A/T. We are based in Colorado Springs and work in Den

    Eh, too much jumping to conclusions that are unfounded. We don't even know what kind of driving is behind these TSI figures. I'm hoping Edmunds will do a true fuel economy comparison between the TSI and TDI, driven along the same route at the same time, etc. I'm also hoping that at some point we will get some actual driving impressions about this car. You've had it for a month and all you've posted about is the backup camera and that the car is capable of heating up in 40 weather.

    Do you track how much those fill ups cost, it would be great to see these "fuel economy updates" @ dollars per mile which is the true test of such a comparison. I realize CA prices are different from other parts of the country but it's still the best measure esp where the diesel does better than EPA estimate on highway and I expect the gas to rarely if ever do that. Thanks

    Looks like the 1.8T is underperforming its EPA numbers. The 2.0T my wife and I had in our '06 Jetta did the same. But at least the Diesel is posting numbers in line with or slightly better than its sticker.

    Looks to me like it's got 2300 miles on it and has not been taken on any highway trips. I guess if you think 27.6 mpg (current best) is the best it's ever going to do...but I don't think so.
