We welcomed a 2013 Honda Civic to Cars.com's long-term test fleet in March to evaluate the unheard of changes Honda made just one year after the Civic's complete redesign. Like our 2013 Subaru BRZ, the one-year ownership experience is tracked in numerous ways including detailed gas mileage logs.
We've only just begun to put the LX sedan trim level with an automatic transmission through its paces after logging 1,400 miles in just over two months. The Civic is mostly being used as a commuter car in and around Chicago with city and suburban stop-and-go driving, a style of driving reflected by the observed 28.4 mpg average. Road-trip season is approaching quickly, and we expect to rack up quite a few trips this summer to test the Civic's 39 mpg highway rating.
Since the BRZ's previous mileage update, both highest and lowest observed mileage have new place holders. A 30.15 mpg fillup marks the highest so far — besting 28.8 mpg — and 18.1 mpg tank the lowest we've seen by 3.3 mpg.
