Often times, automotive luxury brands pump out gussied-up doppelgangers of a cheaper version of the same cars, such as the Lexus ES and Toyota Camry. However, this is far from the case with the Acura TLX. Completely redesigned for 2021, the TLX has a powerful 2.0-liter turbo powertrain, similar to that found in the Honda Accord and Civic Type R. The TLX manages its power much better than these two cars, however, because it offers all-wheel drive. For those who need even more persuasion, a turbocharged 3.0-liter V-6 is available later this year in the Type S trim with 355 horsepower. Equipped to both engines is a 10-speed transmission, which is sure to aid the 2021 Acura TLX’s mpg numbers along with acceleration times. To put this theory to the test, Charlie took an AWD TLX out on the highway to measure its real world highway mpg.
After completing the 100-mile test, the TLX all-wheel drive, not equipped the sporty A-Spec package, returned 29 mpg at highway speeds. The EPA’s highway testing figures corroborate that figure. If you’re looking for a few more mpg and can sacrifice all four wheels clawing you along, the front-wheel-drive version is claimed by the EPA to do 31 mpg. This is not at all a bad fuel-economy rating for a car that makes almost 300 horsepower.
During road trips, traveling tank to tank on the highway would provide a calculated range of 460 miles. Unfortunately, the TLX does not have a very large fuel tank compared to some other vehicles its size, so it will need more pit stops than some performance sedans. But can your bladder last 460 miles? Probably not. And if it can, you need to hydrate.
How We Test
Daily Motor’s real-world highway-fuel-economy test of the 2021 Acura TLX consists of over 100 miles of consistent highway driving. We fill the car using the “three-click method,” meaning running the gas pump on high flow until it clicks, waiting 10 seconds, running low flow until it clicks again, waiting another 10 seconds, then running low flow one final time. We use the lowest-octane fuel accepted by the vehicle’s manufacturer. We then drive 54.2 miles on public highway in one direction and then back in the opposite direction, attempting not to draft or accelerate hard. We set the cruise control at GPS-indicated 73 mph in an attempt to achieve a moving average speed of 70 mph over the entire test. Upon return to the fuel station, we refill at the same pump as the initial fill using the same three-click method. Miles per gallon is determined by dividing the total miles traveled by fuel used. In cases where our observed figure differs greatly from the vehicle’s indicated figure and/or EPA’s estimate, we may recommend a number in between or plan to retest the vehicle.
