I have about 400 miles on my Onyx XT so far, so the engine is still breaking in. My avg mpg on my current tank of gas is a whopping 17.5 ?
Things impacting this include:
- Horrible stop-n-go traffic in the DMV (5 mile one way commute takes me ~25 minutes). I actually like the start/stop feature when I’m waiting several minutes to get through an intersection
- The aforementioned new engine break-in period
- Lead foot syndrome means lots of boost
- Showing off the car to friends and family means lots of boost
I’m starting to notice that using the paddle shifters can drastically increase your mpg. For instance, if you had to accelerate a bunch to get through a light or make a tight merge, you can shift up afterwards to let the CVT know you’re not always driving crazy.
Ultimately if you drive the car conservatively you should probably get around the EPA estimates. But boost is also pretty fun....
I have my first mini road trip (250 miles) for a wedding this weekend, so I should see a good uptick in mpg. Will report back!
On a side note, are there any drive modes on this vehicle (eco, sport, etc)?
