2007	4dr Sedan, ext. 382-horsepower 5.5L V8 7-speed shiftable automatic RWD	Since my driving is about 50-50 city and highway, I average about 20-21 mpg, using premium fuel. All highway is 29-30mpg and all city is 14-15mpg. see full Mercedes-Benz S-Class review
2007	0	While on long trips at 70-80mph I average 32mpg around town it never goes better than 24mpg. Easy on the pedal sure shows results but fully loaded the thing shifts like a two door sports. see full Mercedes-Benz S-Class review

TrueDelta Reviews the Real Gas Mileage of the Toyota Prius

Toyota Prius Real Gas Mileage: Pros
Year	Comment
2016	The new Toyota Prius's EPA ratings are the best of any car without a plug: 54 mpg city, 50 mpg highway. Well, almost. That honor specifically goes to the Prius Two Eco, the variant I tested. With more battery-powered range, some aerodynamic enhancements, and a slightly lower curb weight, the Prius Two Eco scores 58/53. The Ford C-MAX's EPA ratings aren't in the same league: 42/37. When running on gasoline, the Chevrolet Volt doesn't test as well as the Prius: 42/43. But you can plug in the Volt for about 50 miles of electric-only range. The new Honda Civic, among the most fuel-efficient non-hybrid compacts, manages 31/41. In my real-world driving the Prius Two Eco easily beat its EPA ratings, at least in temperate weather. Driven with a very light foot on my standard suburban route, it twice averaged 93 mpg, easily the best in my testing of any car without a plug. When the air temperature dropped into the 40s, though, I couldn't quite manage 60 mpg. On a 70-mph highway in mild weather the Prius averaged just over 60 mpg. Overall for the week it averaged 65 mpg, nearly double the C-MAX and more than double the Civic. My efforts were aided by some of the most thorough driving style feedback you'll find in a car. The Prius scores how you acclerate, cruise, and brake, and provides tips for improvement. It also stores your average mpg daily for a month, then monthly over a long time period. see full Toyota Prius review

2012	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	This is the obvious number one reason to buy a Prius. Unlike Ford, Nissan and others who make hybrid vehicles, the Toyota usually came out ahead in MPG- even in the freezing cold winter of Minnesota. The mileage ranged from 42+ in the winter to well over 59-62 in the spring-fall. My best tank was 601 miles to a tank of regular Costco gas. see full Toyota Prius review
2011	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	Great, a number one factor with high gas prices. see full Toyota Prius review
2011	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	The gas mileage of the Prius is unbeatable. With the price of gas climing at the pump it was time to buy the Prius. see full Toyota Prius review
2011	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	Fuel economy is excellent. Also, the car is very rromy with lots of leg room and can carry some pretty big cargo. I once had 7 people in it for 15 minutes, not recomended as it was reaaly slow and too heavy for its braking power. In 25,00 miles NOTHING has gone wrong or needed repair. see full Toyota Prius review
2010	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	The new Prius is even easier to drive in a responsible manner and has improve MPG from previous models. see full Toyota Prius review
2010	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	it gives the highest mileage among all cars. Beats Honda Insight hands down. see full Toyota Prius review
2010	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	It gets 40+ mpg no matter how badly you drive it. see full Toyota Prius review
2010	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	52 mile commute to work every day and averaging approximately 50 mpg. Reduces USA dependence on foreign oil and carbon footprint. see full Toyota Prius review
2010	4dr Hatch 98-horsepower 1.8L I4 Hybrid CVT FWD	The Prius 50 MPG mixed driving is realistic. The worst MPG I have seen is 45 MPG and the best was 56 MPG. I can only compare that to tests results I have seen where the Insight is 38-42 MPG see full Toyota Prius review

2007	4dr Hatch 76-horsepower 1.5L I4 Hybrid CVT FWD	The engine continues to run when I stop at a stop street, red light or in traffic. That is a sin. There is no excuse to continue running any engine if the car is not moving. see full Toyota Prius review
