2011 Acura TSX Wagon: Excellent Highway MPG
May 24, 2011
I'm late in updating you all, but last week, I drove 800 miles in our 2011 Acura TSX wagon. On the trip north to Half Moon Bay, California, I was hurried, slavishly monitoring the radar detector, driving with no regard for efficiency. Well, here's how that shaped out:
461.7 miles --> 16.760 gallons of 91 octane --> 27.5 mpg
On the way back, though, at your suggestion, I decided to do a fuel economy run, limiting my speed and smoothing my throttle inputs to maximize mpg. I remember someone suggested a 65-mph pace, but that's not realistic on Interstate 5 where the limit is posted at 70 mph and the vibe among motorists is decidedly unrelaxed. So I picked 70 mph as my speed and tried to stay close to that (obviously I had to go slower on certain portions of CA Highway 152 between U.S. 101 and I-5).
Make the jump to see how old leadfoot did.
342.3 miles --> 10.521 gallons of 91 octane --> 32.5 mpg!!
To review, the 2011 TSX wagon is rated at 22 mpg city/30 mpg highway/25 mpg combined.
Cruising at 70 was not the most comfortable pace because of the contentious environment among motorists and truckers on I-5. I would often go up to 75 mph briefly when passing trucks to lessen the severity of the tailgating behind me. Had this been a purely recreational drive, I would have just cruised at 75 mph, even at the expense of a couple mpg.
Still, the fact that I got 32.5 mpg speaks to what a few you have been saying about the TSX wagon's appeal as a fuel-efficient entry-level luxury car. This wagon has more appeal for me now that I know what kind of mpg it can lay down if I'm disciplined and unhurried.
