Cars.com's long-term 2013 Honda Civic and 2013 Subaru BRZ have accumulated roughly 1,000 and 1,100 miles, respectively, since our previous update a month ago. Surprisingly, both are within 2.7 mpg of each other in overall observed gas mileage despite one being an enthusiast's sports coupe and the other a bean-counter's economy car.
The Civic's highest tank average of 33.58 mpg is up from its previous best of 33.11 mpg and bumps the overall average up a few ticks to 28.53 mpg after 2,500 miles. Hold on: 28 mpg? The Civic has half the total miles of our BRZ; it joining the Cars.com long-term test fleet a few months after the Subaru and has far fewer highway miles under its timing belt. Our Civic's overall average hovers right on top of its EPA-estimated 28 mpg city rating.
The Civic rotates among Cars.com staffers just like the BRZ. The intention for both cars is to accumulate miles, though the Civic has yet to stretch its legs at highway speeds for very long with much of its use coming as a city commuter. The BRZ made a road trip from Chicago to Detroit right off the bat in January for its introduction at the 2013 Detroit auto show as Cars.com's Best of 2013 winner along with the 2013 Scion FR-S. Apparently some of the Cars.com staff enjoys self-inflicted pain, taking the stiff-riding BRZ on additional road trips, or maybe its fun factor is irresistible. In this update, the BRZ's best recorded tank average is set slightly higher at 30.8 mpg, up from 30.15 mpg.
