TrueDelta Reviews the Real Gas Mileage of the Subaru Forester

Subaru Forester Real Gas Mileage: Pros
YearComment
2014 Subaru's latest engines when paired with a continuously variable transmission (CVT) earn much better EPA numbers than their ancestors. The 2013 Forester rated only 20 mpg city, 26 mpg highway. The 2014 checks in at 24/32, about as good as you'll find in a compact crossover with all-wheel-drive. The CR-V manages 22/30, the RAV-4 22/29. Only the Mazda CX-5 comes close, 25/31 or 24/30, depending on engine size (you want the larger one with the slightly lower EPA numbers). In suburban driving I observed trip computer averages of 23 to 27 once the engine was warmed up. But 15 for the first couple of miles--it was cold and snowy the week I had the car. (This big difference when the engine is warming up is typical, but something many people don't realize when comparing their winter averages with the EPA ratings.) Summer fuel economy should be better. see full Subaru Forester review

I drive mainly around town and average 26 overall. On a highway drive, I get around 33. My previous vehicle was a 2009 Escape V6 AWD, this is a definite improvement on fuel economy. I could rarely get 30 on the highway. Typically around 27. see full Subaru Forester review

The suggested/promised MPG is pretty high and, while I haven't hit those numbers on average, I can say that I'm getting better mileage than I was getting in a smaller, non-AWD, non-SUV "sporty" car with a smaller engine. The built-in value of the vehicle is top notch... For the price, I got more equipment than I would have gotten on much of the competition...! A truly great value for the bucks....! see full Subaru Forester review

Fuel econmy is OK in summer, again would be good vehicle for california. However in Canada where we get lots of cold weather fuel economy is very poor, in fact it is worse than my BMW, which has twice the horsepower and my Honda Van, what gives?

Some people look at the XT's ratings and think 19-24 is horrible AND you have to buy premium gas! Not me. Don't mind it one bit. Do the math: $3 extra over regular unleaded at the pump every fill-up, 4 times a month (although I fill up less), that's $12/month. Multiply by 12 months and you're looking at $144/year! That's nothing to pay for the fun added to your driving experience! Some people pay more than that for one nice dinner out! see full Subaru Forester review

2004 4dr SUV turbocharged 210hp 2.5L I4
4-speed automatic AWD
Fuel economy is hit or miss. I've seen anywhere from 14-20 in the city with no discernable difference in driving habits. On the highway I've seen anywhere from 19-26. Once again, with no discernable difference in driving style, speed, or weather. There is just no predictability. see full Subaru Forester review
 

TrueDelta Reviews the Real Gas Mileage of the Cadillac CTS

Cadillac CTS Real Gas Mileage: Cons
YearComment
With the 2011 528i, BMW pioneered the use of a turbocharged four-cylinder engine in a $60,000 midsize sedan on this side of the Atlantic. The point: fuel economy, specifically EPA ratings of 22 mpg city and 33 mpg highway even with all-wheel-drive (24/34 with RWD). Audi followed with an A6 2.0T good for 20/29 (25/33 with FWD) a year later. The new CTS takes the path blazed by the Germans, but much less effectively. Though the Cadillac weighs significantly less than the Audi or the BMW, its EPA ratings are lower, 19/28 (20/30 with RWD). The same is the case with the two 3.6-liter V6 engine options, even though unlike the turbo four they can be paired with an eight-speed (instead of a six-speed) automatic. The rear-drive-only Vsport barely evades the gas guzzler tax with ratings of 16/24. Even the 445-horsepower turbocharged 4.4-liter V8 in the BMW 550i does a bit better. In my real-world driving, the CTS's trip computer confirmed this shortcoming. Even considering that the outside temperature was near zero, post-warm-up averages that clustered around 18 were disappointing. Only by driving the car with a light foot could I nudge the suburban average over 20, and even then not much over. A 320-horsepower 3.0-liter 640i Grand Coupe tested a week earlier in similar conditions did at least one mpg better than the 272-horsepower, 2.0-liter Cadillac. And when I tested a 528i xDrive in slightly warmer temps it often managed 25 mpg (in an EcoPro Mode the Cadillac lacks). In one trip this BMW even touched 30. see full Cadillac CTS review
