TrueDelta Reviews the Real Gas Mileage of the Toyota Corolla

Toyota Corolla Real Gas Mileage: Pros
Year	Comment
2014	Those seeking to maximize fuel economy should check out the Corolla LE Eco, with EPA ratings for 30 mpg city, 42 highway. The regular LE checks in at 29/38, and the S at 29/37. Even the last is within spitting distance of the best in the segment, including the 30/39 Sentra. In my efficiency-minded suburban driving the trip computer reported an average of 37.7, a bit better than the 36I managed with the Sentra. Driving with less care for fuel economy netted 32, about even with the Nissan. The Toyota couldn't quite match the Nissanona 65-mph highway drive, though, with a two-way trip computer average of 38 vs. 40 (quite close to those EPA estimates). see full Toyota Corolla review

2010	4dr Sedan 132-horsepower 1.8L I4 4-speed automatic FWD	Fuel economy is great, as expected with 1.8 I4. EPA rated city driving at 28MPG but i have never been below 32. When cruising at 65 with A/C off, 40MPG is possible. The sole reason i bought the car was for economy. Paired with great MPG and great price, I would say this beats out a Prius if you want to save money. see full Toyota Corolla review

2009	4dr Sedan 132-horsepower 1.8L I4 4-speed automatic FWD	Lost 4 MPG after Technical Service Bulletin work performed to decrease oil use. Oil still disappearing. see full Toyota Corolla review
2007	4dr Sedan 126-horsepower 1.8L I4 4-speed automatic FWD	This car gets 25 City, 35 Highway. It looks like it should be able to do better, but it does not. The 3-speed Automatic with Overdrive (4-speed in reality) is dated and is only okay with the engine's performance. The engine itself, the 1ZZFE, has very few flaws, but is the final evolution of a 90's engine design, that gets okay horsepower, but goes through gas more than it should. And when they get older, they do go through more gas than they should. In addition, the engine can't handle E10 in cold weather (regular gasoline with "up to" 10 percent ethanol) without problems, requiring you to spend more on "REC" fuel, which is non-ethanol pure gasoline. On top of that, the drive by wire throttle has a noticeable delay between the hair trigger throttle and the engine surging forward, making smooth starts with the automatic difficult. see full Toyota Corolla review
2005	4dr Sedan 170-horsepower 1.8L I4 6-speed manual FWD	The gearing which keeps the engine in its power band keeps it at 4k RPM on the highway (I go fast). 30MPG on premium fuel is not justified by the modest increase in power. see full Toyota Corolla review

2007	4dr SUV 200-horsepower 3.0L V6 4-speed automatic AWD	For some reason when new Michelin All Terrain tires with Nitrogen air replaced the Champions from the factory, it plummeted to 17 & 20 mpg. No explanation from Michelin, Costco or Ford/Mercury - they have no idea why. see full Mercury Mariner review
