TrueDelta Reviews the Real Gas Mileage of the Audi A4 / S4 / RS4

Audi A4 / S4 / RS4 Real Gas Mileage: Pros
YearComment
2017 Everyone has been switching to turbo fours in pursuit of fuel economy. Despite being such a quick car, the new A4 manages EPA ratings of 25 mpg city, 33 mpg highway with front-wheel drive and 24/31 with all-wheel drive. If you're willing to trade off some performance for even better numbers, and don't require all-wheel drive, the new 190-horsepower "ultra" achieves 27/37. In my driving the A4's trip computer reported averages as high as 36 mpg in the suburbs and 34 mpg on the highway. Mid-to-high 20s happened without even trying to be economical. Lexus, perhaps because it's new to turbocharging, can't match these figures. The IS 200t scores 22/32, while the IS 300 (with AWD) manages only 19/26, a full five mpg short of the Audi. see full Audi A4 / S4 / RS4 review

Very surprised! Drive 80 Hwy / 20 City driving. If I watch how I accelerate (cruising speed not so much; I drive 110-125 on hwy). Averaging 6-7.5L/100km. (700+km per 55L tank every fill up). see full Audi A4 / S4 / RS4 review

Despite the supercharger and high performance, this vehicle gives me about 6.8l/100km on the highway on average - amazing fuel efficiency. This is a very welcome bonus. see full Audi A4 / S4 / RS4 review

The diesel version has MORE torque and power AND has a far better range (about 700 miles for 2L diesel engine), I dislike the 22-24 mpg for the combined driving (mostly city). Those are still good numbers for its class. Sucks when have to pay $3.87/gallon see full Audi A4 / S4 / RS4 review
2008 2dr Convertible 420-horsepower 4.2L V8

No 420hp car is going to sip fuel, but the fuel tank is small (14.5 gallons) and thus needs filled too often. see full Audi A4 / S4 / RS4 review

Overall fuel economy barely acceptable on premium fuel. Highway fuel economy is fine but city economy stinks. 21 MPG driving 70% highway miles. However, better than Infiniti G35x see full Audi A4 / S4 / RS4 review

2013 4dr Sedan 328-horsepower 3.7L V6

What the powertrain giveth, the fuel economy taketh away. Nissan's VQ engines just seem to be thirsty - if you commute in heavy traffic, especially for short trips, don't be surprised at 15.5-16 mpg tanks. I don't know what mostly-highway commuting would look like, but maybe 22-25 mpg depending on driving style. see full Infiniti G review
2010 4dr Sedan 328-horsepower 3.7L V6

To be honest, it is exactly what I expected, so no real beefs with it. That said, if you are looking for a car that gets better than 19 or so combined, this is not it. Decent freeway miles (24-27/g) but in city it is hard to beat 16/g. see full Infiniti G review

With such a large displaced engine and so much power you will find that you will have so-so mpg if you drive mainly in the city like I do. Especially if you are a "spirited" driver like I tend to be. I am averaging about 14-16mpg 95% city. On the highway its a different story. I have averaged up to 28mpg @ 78mph, I kind of wish I drove more on the highway. see full Infiniti G review

While not terrible, ~20mpg is by no means phenomenal. Relatively comparable cars get ~23-27mpg, but typically also have smaller engines which explains a good portion of the difference. see full Infiniti G review
