2013 Subaru BRZ Long-Term Road Test


2013 Subaru BRZ: Utah Road Trip Fuel Economy

July 31, 2013

2013 Subaru BRZ

I've complained about our long-term 2013 Subaru BRZ's feeble power on my recent road trip to Utah. But as I've been hinting, the BRZ returned stellar fuel economy, even though its 2.0-liter engine got a workout on the mountain passes, and even with 75-mph speed limits on much of Interstate 15.

Over 1,726 miles, the Subaru averaged 31.9 mpg. Not only does that far surpass its lifetime average of 26.5 mpg, it's well ahead of its 30 mpg EPA highway rating.

Since I was driving through remote stretches of desert for much of the trip, I didn't try to go for any range records. Actually, I really thought I was going to get a 400-mile tank on the return leg, but I chickened out and paid $5.00/gallon for 91 octane in Baker, California. That tank netted 381.7 miles, which is still well ahead of our previous range record of 356.9 miles.

The BRZ also recorded a new fuel economy high. Its previous best was 32.5 mpg, and that record was broken on one 236.1-mile tank, which netted 33.3 mpg. But then I decided to top up early once I entered the town of Moab, and my small 89.7-mile tank was good for 34.5 mpg.

    Fuel economy is quite good, considering the motor gets spun-up near the top of the tach on a few occasions. I like many things about the BRZ, but the one issue that kills any thought of buying one is that dead spot in the middle of the power band. I don't think I would enjoy having the motor lay down between 3 & 4 grand.

    re torque hole between 3 & 4k - I wonder, is this even noticed anywhere but on a dynamometer? With partial throttle during normal driving, it's probably not apparent. With full throttle and redline shifts, gear changes should drop the rpm to *above* 4k. (This isn't a 4-spd after all.) Just wondering.

    You bought gas in Baker?? I thought everybody who uses I-15 knew not to do that. If there is any doubt about getting to at least Victorville you fill up in Las Vegas. The good gas mileage in Utah does not surprise me. I have seen the same with a naturally aspirated vehicle when touring around at altitude. Oxygen is short so less fuel goes in for a given throttle opening. As a result you are running with the throttle at wider opening which reduces pumping losses and improves gas mileage.
