What Our Members Are Saying about the Real Gas Mileage of the Volvo S80

Volvo S80 Real Gas Mileage: Pros
YearBody/PowertrainComment
2008 4dr Sedan 235-horsepower 3.2L I6
6-speed shiftable automatic FWD		 Even though it says it requires Premium in Summer some where in that manual it states I can use 87~89 octane gas without harming the engine. That is helpful to know. With premium fuel and my mainly highway driving with only 2 persons on board we get 25MPG see full Volvo S80 review

5-speed automatic FWD		 Very small comparing to other cars see full Volvo S80 review

4-speed shiftable automatic FWD		 Excellent city and highway mileage. see full Volvo S80 review
2001 4dr Sedan 168-horsepower 2.4L I5
5-speed automatic FWD		 I've had this car for 13 years now and the mpg has always been very good. Being a European model (2.4 litre petrol auto - 170 bhp) it does not compare directly with any US models. I have the air con on 100% of the time. If I keep to the speed limit - 80 -85 on the speedo I get 35 mpg (English gallons!) without any problem. On a holiday trip to Portugal doing long distance driving and at slightly slower speeds - say 70 mph on the speedo - I managed 40 mpg over nearly 1,500 miles. In town stop start driving I will usually get 25 mpg. Impressive figures I think for a 13 year old vehicle weighing as much as it does. see full Volvo S80 review

2007 4dr Sedan 235-horsepower 3.2L I6
6-speed shiftable automatic FWD		 Very good fuel economy overall but running the AC continuously does produce a noticeable 2-3 mpg decrease in fuel economy. see full Volvo S80 review

5-speed shiftable automatic RWD		 16 city/21 highway. Buy it only if you can afford it with out complaining. see full Cadillac STS review
2005 4dr Sedan 320-horsepower 4.6L V8
5-speed shiftable automatic AWD		 This car is thirsty. I live in flat country and I get 15 mpg with 80% highway traffic. I only get 19 mpg on trips. It probably needs a 6th speed overdive for the highway. see full Cadillac STS review
