Actual experience: 28.8(-)mpg, 43% City/57% Hwy vs EPA estimates 28 city, 31 combined (weighted 55 city, 45 highway), and 37 highway. We use cruise control almost in all driving conditions above 25 mph; we use top-tier gasolines as recommended by GM and Chevrolet. We maintain tire pressures checking at least monthly. With this automobile, we use nitrogen in its 18 inch wheels/low profile tires. Based on our prior experiences with GM automobiles and the way we drive and maintain our cars, we expected better,
The 2017 Cruze Hatchback Premier RS is a superlative car especially with its additional options for passenger comfort and driver confidence. Ours has no substantive defects except one - fuel economy. By this forum, that has not been a significantly issue with Cruze non-diesel owners for the last several years. Left rear passenger door requires more "umpf" than others to be closed; the others close with almost no effort. Tire Pressure Monitoring System (TPMS) is sensitive with the 18 inch wheels. Driver Information Center (DIC) is very intuitive -- annoyance is that reported fuel economy averages for last 25 miles, 50 miles, and 450 miles are nearly always about 10-15%+ more than actual fuel economy, as measured by miles driven/gallons consumed. Tripodometer reset at every fuel-up averages 3-8%+ more than actual fuel economy.
We know that fuel economy varies across the different Cruze models, and our current Cruze is the heaviest among the 2017 models. We have purchased two prior Cruzes - a 2011 Eco and a 2012 Eco. Other GM cars we have owned include a 2005 Chevrolet Venture LT and a 2007 Pontiac Vibe. ALL of these automobiles routinely met or exceeded their EPA estimates, as we have driven them and based on fuel logs we keep. Only the Vibe is no longer in use within our extended family.
We know that fuel economy variance is from a number of factors:
- driver variance and vehicle load (EPA fuel economy ratings acknowledges)
- environmental differences (weather and road types and conditions) (EPA fuel economy ratings acknowledges)
- fuel differences (EPA fuel economy ratings acknowledges)
- variation within GM production cars (Chevrolet secret?!?)
Chevrolet Customer Assistance stands behind the EPA estimates. Know how these are obtained, know what they represent. Old EPA ratings gave a range, current are point estimates only. What the variance is, due to differences among production cars of the same model, is known only to GM/Chevrolet. Dealers don't want to know or obtain.
Our experience has been very consistent in our Cruze's first 4184 miles of use. One dealer checked fuel stoichiometry after 3000 miles, and the measurements were within specification; and, asked us to drive more miles and track the fuel economy claiming with additional "break-in" the fuel economy may improve. For this car, we keep its fuel log public at fueleconomy.gov (you can see its updated average only) and fuelly.com (the fueling log is fully accessible). rxmonchamp (fuelly.com) with his 2017 Cruze HB Premier achieves fuel economy meeting and exceeding EPA estimates, based on his log of his car's first 5541 miles.
Actual experience (18 fuelings) until next fueling: 28.8(-)mpg, 43% City/57% Hwy vs EPA estimates 28 city, 31 combined (weighted 55 city, 45 highway), and 37 highway. We use cruise control almost in all driving conditions above 25 mph; we use top-tier gasolines as recommended by GM and Chevrolet. We maintain tire pressures checking at least monthly. With this automobile, we use nitrogen because of the 18" wheels/low profile tires. Others in this forum have reported rapid drop off in fuel economy above 60mph with earlier model year Cruzes that have 18" wheels. Best fuel economy highway has been 33.4mpg with most miles driven at 60mph, two passengers, minimal cargo/luggage. At this point, fuel economy underperformance is 12.5% adjusting based on the EPA combined estimate method (28x0.43 + 37x0.57)=32.95mpg expected vs 28.8mpg actual.
Not sure how Chevrolet stands behind a specific car that is under warranty and underperforming to the EPA estimates substantially. One dealer has said that with the computers-controlled 1.4L Turbo, there is nothing that dealer's service department can offer. We are looking forward to experiencing that Chevrolet will correct our car's underperformance, and will use this forum to acknowledge any Chevrolet actions taken. A "case" has been open since January 20.
