Here’s my Alltrack fuel economy findings after two years and 20k miles in my 2017 Golf Alltrack:
Floor: 20 MPG, Ceiling: 30 MPG
Floor: 30 MPG, Ceiling: 45 MPG
The Truth About Cold Engines
There’s a city MPG caveat. Anyone can get 10 MPG city if you just drive a mile. That’s because there’s a hole you have to dig out of every time you start your car, and that hole is the warmup period. When the engine is cold, like when you start it, it’s just going to give you crap MPG. Every ICE (internal combustion engine) car is like this. Just please, don’t idle your car to warm it up. This pollutes more than if you just drive.
When the warmup is complete, usually after 1-3 miles or around 5 minutes, you’ll get decent fuel economy. My figures include warmup time, but exclude trips of less than 3 miles.
Driving Style Affects Fuel Economy
The reason I have floors and ceilings on my MPG numbers is because driving styles vary… in my case they vary wildly. Sometimes I drive fast (but safely). Sometimes I accelerate very slowly and try to preserve momentum to reduce the frequency of using the gas pedal.
