The 2021 Genesis G80 arrives as an all-new vehicle for the model year. We already knew the new G80 would arrive with a new design, more advanced technology, and more luxury features, but one thing we weren’t sure of was fuel economy. The 2021 G80 has a new lineup of powertrains compared to the 2020 model that, according to the EPA’s official fuel economy figures, will make the 2021 G80 far more efficient than the 2020 model.

For 2021, the G80 is available with two new powertrains. The base engine is now a turbocharged 2.5-liter four-cylinder that’s paired to an eight-speed automatic transmission. With rear-wheel drive, the G80 is rated to get up to 26 mpg combined. Going with all-wheel drive lowers the combined fuel economy rating to 25 mpg.

Thanks to the new four-cylinder engine, the 2021 G80 is far more efficient than last year’s model. Last year, the standard powertrain in the G80 was a 3.8-liter that was rated at up to 21 mpg combined with rear-wheel drive and 20 mpg combined with all-wheel drive.

While the 2021 G80 is more efficient than last year’s model, the trade-off comes in horsepower. The new 2.5-liter turbo four-cylinder engine is rated at 300 horsepower and 311 pound-feet of torque, while last year’s 3.8-liter V6 produced 311 hp and 293 lb-ft of torque. We think the majority of consumers will be fine with the trade-off.

At the top of the range, the 2021 G80 now comes with a twin-turbocharged 3.5-liter V6 that’s rated at 375 hp and 391 lb-ft of torque. The engine also comes with an eight-speed automatic transmission. With rear-wheel drive, the V6 is rated at up to 22 mpg and 21 mpg combined with all-wheel drive.

Those figures are better than both of last year’s available powertrains. Last year’s twin-turbo 3.3-liter V6 was rated at up to 20 mpg combined, while the available 5.0-liter V8 could get up to 19 mpg combined. With the new twin-turbo 3.5-liter V6 engine, consumers are getting more power than last year’s available 3.3-liter twin-turbo V6. That engine was rated at 365 hp and 376 lb-ft of torque. The optional 5.0-liter V8 engine is far more powerful than anything offered on the 2021 G80, though, as it was rated at 420 hp and 383 lb-ft of torque.

In addition to being more efficient than last year’s model, the 2021 G80 compares well to the competition. The BMW 5-Series can get up to 28 mpg combined, Mercedes-Benz E-Class is rated at up to 26 mpg combined, Audi A6 has a combined rating of 27 mpg, and Lexus ES can get up to 26 mpg combined.

Surprisingly, the G80 is also more efficient than the smaller, compact G70. That sedan is rated to get up to 25 mpg. The large G90 is far less efficient than the other two sedans, carrying a combined fuel economy rating of up to 20 mpg.
