2014 Chevrolet Impala Mileage Update: 5,456 Miles

Our long-term 2014 Chevrolet Impala can't seem to return decent fuel economy; it's still averaging a few miles per gallon short of its 22 mpg combined EPA rating. We know the comfy sedan can exceed its 29 mpg highway rating with cruising mileage up around 31 mpg, but it recently logged a new lowest-recorded tank of 17.36 mpg, falling short of its 19 mpg city rating.

Chevrolet Impala is the best

A little car with truck mpg and sticker price. Why not just buy an SUV or Pickup?


I think the new Impala is a good car, but it seems like GM can easily get more power but rarely gets better average fuel economy than past models. I can match this fuel economy on our 2000 Impala LS with 231,000 miles and a 4 speed trans (I'm averaging 28.7mpg right now, but hit 31.5mpg last summer on a trip). Our car still looks very nice inside and out, but I would rather have ours with one of GM's best engines ever (3800) vs a more powerful but more complicated engine. I'm hoping for 300,000 miles?

When our's finally goes, I'm looking at a new Accord with their 4 cyl. and CVT. I heard Honda has that setup nailed down.
