2015 Volvo S60: New Best MPG, But Average Still Far Below EPA
July 14, 2015
The miles aren't piling up as quickly as we figured. Our crack driver squad added 1,212 miles to our 2015 Volvo S60 this month, bringing the grand total up to 6,692 miles. But we'll need to average more 1,800 per month from here on out if we're to reach our 20,000-mile goal. Good thing summer road trip season is just around the corner.
Much of our driving has been local. Sure, we've taken it on a couple road trips, but mainly north on Interstate 5, a visually uninteresting and maddeningly competitive stretch of freeway where the prevailing flow of traffic will bowl you over if you don't keep up. This route is not conducive to kicking back and letting the scenery glide past while your car sips fuel, even if that's your style.
Perhaps that's why the Volvo's average fuel economy continues to lag behind its EPA combined rating. The feds say it should be hovering around 28 mpg, but our Volvo's lifetime average is just 23.7 mpg with June factored in. This barely matches its EPA city rating.
Brent Romans took it to Fresno this month, and he tried hard to conserve on the way back. His 30.5-mpg effort is a new best tank for the S60, too, but even he admits he didn't get the most out of it thanks to the I-5 shuffle.
A new worst-fill of 14.9 mpg came courtesy of Mark Takahashi, who lives deep within the impacted road system that is west Los Angeles. But his new low hardly counts. This was an abbreviated tank of just 42.9 miles, all of it in the worst traffic imaginable. We usually prefer to let things play out over a couple hundred miles of varied driving before filling up.
But Mark was on a mission. He tanked up when he did because he was starting an official lap around our vehicle evaluation loop. Fuel economy isn't the main point of the exercise, but it's something we track with care. His lap amounted to 27.8 mpg, a virtual match of EPA combined.
The stats break down like this.
Worst Fill MPG: 14.9 (new low, but an abnormally premature fill)
Best Fill MPG: 30.5 (new high)
Average Lifetime MPG: 23.7 (4.2 gallons per 100 miles)
EPA MPG Rating: 28 combined (24 city / 35 highway)
Best Range: 410.5 miles
Current Odometer: 6,692 miles
