2015 Volvo S60: Fuel Economy Update for November: Average Fuel Economy Barely Budges

by Cameron Rogers, Associate Editor on December 4, 2015

2015 Volvo S60

After a car has been in our fleet for a few months, its average fuel economy more or less levels off and stays consistent throughout the rest of its stay. Case in point: the 2015 Volvo S60. Even though we averaged 24.2 mpg over 1,381 miles in November, the S60's overall fuel economy increased by just a tick, from 22.9 mpg to 23.0 mpg.

That's about what the average has been since the end of April. The best fill for the month was 28.8 mpg over 425 miles, set by Messrs. Romans and Schmidt.

As Brent noted last month, we've produced our share of pessimistic headlines about the disparity between the S60's EPA-estimated fuel economy and our own fill ups. But as commenter prndlol noted on that post, our average of 23.0 mpg is fine for a car that makes 302 horsepower.

I agree. For comparison, our long-term 2013 Cadillac ATS had 272 hp on tap from a turbocharged 2.0-liter engine. The ATS was less powerful and slightly slower than the S60 in a 0-60 mph race, and it finished its tenure with us with an average of 22.1 mpg.

Our last long-term S60, a 2012 model with a 250-hp turbocharged five-cylinder, averaged 22.8 mpg. On the other hand, our current 2015 Acura TLX comes with all-wheel drive, and a 3.5-liter V6 just 12 hp shy of the Volvo. It has returned 24.2 mpg so far and has achieved a best fill of 33.7 mpg versus the S60's 30.5 mpg.

So while our S60's real-life fuel economy falls drastically short of its EPA ratings, it is more powerful and efficient than a couple of past long-termers with turbocharged, small displacement engines. Unfortunately, the S60's trick super- and turbocharged engine hasn't yet matched or beaten the fuel economy of the TLX's naturally-aspirated V6 in real-life driving.

That said, I would still buy the S60 for its more responsive engine and fantastic seats.

Worst Fill MPG: 14.9 mpg
Best Fill MPG: 30.5 mpg
Average Lifetime MPG: 23.0 mpg
EPA MPG Rating: 28 Combined (24 City/35 Highway)
Best Range: 460.7 miles
Current Odometer: 14,983 miles
