Official 2018 Chevrolet Equinox Diesel Fuel Economy Numbers Don’t Quite Get to the 40-MPG Mark

General Motors’ expectation that the 2018 Chevrolet Equinox Diesel would climb to the arbitrarily important 40 miles per gallon marker will not be fulfilled by the production Equinox.

In accordance with Environmental Protection Agency procedures, the Equinox 1.6TD comes up short of the 40-mpg highway marker by a single mpg. 

Released today by General Motors and likely to be featured on the EPA’s fueleconomy.gov website on August 15th, the front-wheel-drive 2018 Chevrolet Equinox Diesel is rated at 28 miles per gallon in the city and 39 on the highway, for a combined rating of 32 miles per gallon.

Diesel-powered, all-wheel-drive Equinoxes share the 28 mpg city rating and the 32 mpg combined rating, but drop to a 38 mpg highway rating.

GM calls the 39 mpg highway result “expected segment-topping” fuel economy, but we’ve yet to see what Mazda achieves once the EPA certifies the CX-5 Skyactiv-D.Compared with other editions of the Equinox, the 1.6TD offers a combined rating equivalent to the best highway rating of any of the other models: the front-wheel-drive 1.5T, which has a city rating of 26 mpg. The thirstiest Equinox, meanwhile, is the hi-po 2.0T all-wheel-drive, for which premium fuel is recommended. It’s rated at 22 mpg city, 28 highway and 24 combined.

Prior to the CX-5 diesel’s arrival, the Equinox 1.6TD’s most efficient rivals are the Nissan Rogue Hybrid and Toyota RAV4 Hybrid, which have combined ratings of 32-34 miles per gallon, though the Equinox is measurably more thrifty on the highway.

The 1.6 turbocharged diesel, offered in top Equinox trims, commands a premium over the 2.0T, but, due to equipment differences, the comparison is not as straightforward as you’d expect. Including fees, the 2018 Chevrolet Equinox Diesel is priced from $31,435.

Sales expectations are modest. GM hopes to see 5 percent of Equinox buyers opt for the diesel, which would have translated to roughly 1,200 U.S. sales in July 2017.
