The Buick Verano earns credible EPA gas mileage ratings, but when it's compared to its own next of kin, those numbers pale.
It's a platform-mate with the Chevy Cruze, which has a smaller pair of four-cylinder engines on its features list. The Cruze earns up to 42 mpg highway with its 1.4-liter four--and 46 mpg highway with its new diesel option.
The Verano instead offers a larger-displacement 2.4-liter four-cylinder that drags on its fuel economy. Outfitted with its standard six-speed automatic, the Verano is pegged at 21 miles per gallon city, 32 mpg highway, and 25 mpg combined by the EPA. It's not only lower than the Cruze, but also lower than non-premium compacts like the Ford Focus and Hyundai Elantra, though it's likely the Verano's figures will be in lockstep with the Mercedes-Benz CLA, its newest competitor in the premium-compact class.
The Verano Turbo makes the base four-cylinder engine look a bit more compromised. It's rated at 21/30 mpg with the automatic, and 20/31 mpg with the 6-speed manual transmission, and 24 mpg combined with either. That's still a good bit off the pace of mid-size, mass-market sedans like the Nissan Altima, Honda Accord, and Ford Fusion, but more acceptably close to their performance-oriented configurations.
