5 Least Fuel Efficient Audi Models of 2023
Audi is an industry front-runner in electrification and zero-emission production cars. But there are still quite a few gas guzzlers in the brand's lineup.
Audi S8 - 15/23 MPG
The sportier version of the Audi lineup's holy grail of luxury, the Audi S8 is powered by the manufacturer's trusty 4.0-liter V8 aided by twin turbochargers. In this application, the mill puts down a mighty 563 horsepower. The figure to highlight here, though, is the high curb weight of 6,393 lbs. Hence, the powerful engine yields 15 MPG in the city and 23 MPG on the highway on average.
Audi RS6 Avant - 14/21 MPG
The mechanical elements of the RS6's power plant are nearly identical to that of the aforementioned S8, and a number of other high-performance machines in the Audi lineup. In this case, the 4.0-liter V8 is capable of 591 horsepower. Though the RS6 Avant weighs less than the S8, the performance-oriented setup of the power source results in a worse fuel economy of 14 in the city and 21 MPG on the freeway.
Audi RS 7 - 14//21 MPG
The RS7 is practically identical to its station wagon sibling in terms of the numbers. Similar weight, the same engine and power output, and the same EPA-estimated fuel economy.
Audi RS Q8 - 13/19 MPG
The RS Q8 falls in the same high-performance category as the two previous models on this list. It's powered by the same twin-turbo 4.0-liter engine. Interestingly, however, it weighs quite a bit less. With a curb weight of just under 5,500 lbs, it's over 500 lbs lighter than the RS6 and RS7. But the taller frame of the powerful AWD SUV brings the fuel economy to 13 MPG in the city and 19 MPG on the highway.
Audi R8 - 14/23 MPG / Audi R8 quattro 13/18 MPG
The RWD versions of the final edition of the Audi R8 have a gas mileage that tops those of the RS6 and RS7 with 14 in the city and 23 on the freeway. The figures are lower for the GT model, which comes in at 14/21. But the quattro models, the most powerful iteration of the V10-powered supercar, have an EPA-estimated MPG of 13 in the city and 18 on the highway, which makes it the biggest gas guzzler in the Audi lineup. As with most of these amazing vehicles, though, it's a lot more about the smiles per mile than the miles per gallon.
