Highway MPG
Just went to East Hampton from NYC; averaged 36.7 MPJ, going 65-70 MPH
2021 Acura TLX/ASPEC
Pretty damn good
City MPG is half that, or worse

that's pretty good for a mid-size sedan.

I have yet to see 29 mpg on pure highway on my AWD A-Spec and I drive in Normal/Comfort 95% of the time for fuel economy.

Even the V6 first gen TLX V6 had some reports of similar mpg on the highway. The 4cyl fwd some higher. Depending on your traffic and terrain you can go over the EPA estimate on highway/city with most cars today. Although there are some cars of the same make/model that just get crap mpg for whatever reason (some people just get that car and the dealership will not care all that much). I found with the many Acura's we have had that fuel economy creeps up and hits peak after getting close to 20k miles so always got better from when brand new. Not to say it was a lot but maybe 2 to 3 mpg from when it was new. I don't do a ton of highway driving, mostly lower traffic secondary roads and then 5 to 10 miles on I95.

Think in addition to the TLX-S power shortage there is also a mileage shortage. Hopefully they will work it out & apply a OTA ECU update.
Return - more traffic & construction = more throttle usage..

Highway miles are pretty easy to beat EPA estimates averaging 80 mph. Hard to average that on an 8-10 hour trip mostly highway with stopping for gas and such and never hit a traffic jam which I always hit a few. I can get over 28 mpg fairly easy just driving around off the highway if I try but usually my right foot gets heavy. Biggest hit on MPG for me is the cold start mpg for the first 5 minutes on a 15 min round trip when cold the mpg is less than half of normal for part of the time. Been on a lot of long drives and could never average 80 mph on any and that is not for lack of trying. Last trip with nearly 30 mins on PA turnpike going, possibly, 15-30 over that average of 80 in a group of cars still only ended up at 68 mph average on a 6 hours trip almost all highway.

I got almost 33 mpg on a two hour drive to Manhattan, Kansas and I was still averaging about 31 mpg when I got home and that included a little bit of city driving before heading home.

Yes you need to make a lot of runs well over the average to make the average with passes pushing into triple digits. I like to catch on a group of 5 or 6 cars making a fast run as opposed to running alone down the road. Clear run 85/90 will make 33.X on the instantaneous readout.
Considering two C&D tests were 1/4 mile 12.2/12.3 @ 116/115mph its pretty good on straight 93.
Agree short runs are the worse. Closest stores to the house are 8 miles away. Honey Do's drain the car quickly. My normal daily driver is Sport +. I live outside Raleigh in the county so my "city" driving is better than a true intown number. Its 22MPG pretty consistently. Over the road I use "adaptive" GPS automatic selection to optimize fuel usage & enable 8TH overdrive. 8th my highest gear is locked out in any thing with a Sport label.
Anything like that with the 10 speed? Have a 10 in the SUV but never noticed or RTFM

I got 30.7 MPG over the course of 90 miles. My speeds varied from 45-90. It was I would say 75-85% highway. This was I think a mix of shell and costco gas (93 Octane) in my Advance sh-awd.

Everyone's dividing the miles driven (trip odometer reset every gas fill up) by the actual gallons replenished according to the pump/receipt, right?

Reasons I don't bother with the receipt thing outside of being to lazy, hit the NO button, is I am not sure with the pump automatic cutoff that the tank is being filled to the same level each time. Second over they years the spread is just not that important to me.

Too anal for me, I have always done MPG when I do it by the "good enough for government work" standard. Quick & dirty check, usually put in around 6 gallons of 93 at each end of the run. Gas gauge says less than 1/2 a tank used......rated capacity 13.7 gal, useable capacity ?

I don't have to worry about the tank being filled to the same level because if I had reset the trip odometer at the last fill up, then the miles accumulated consumed exactly the gallons of gas at the pump for the current fill up.
I do the math on my iPhone as soon as the pump fills the tank completely!

I find the onboard computer is usually pretty accurate. I usually confirm with the method that Elin mentioned a few times when driving a new car, just to see how accurate the car is.
On the topic of mileage and topping off the gas tank, I saw this in the owners manual (yes, I'm one that actually RTFM)
No idea why this is called out for the TLX-S and how it would be different than the 2.0T engine. Strange.

Car computer did the math; it's legit!

Anyone with a Type S that can report highway mpgs yet? I know it's rated at 24 mpg with the summer tires and 25 with the all seasons. The Redline review guy said he was seeing 26 mpg on the highway with the summer tires. Hoping to get some real world numbers from some of the new owners.

The problem is the "rigorous" method I described is often much lower than what the car reports since you last reset the trip odometer.

FYI: After I noticed the 36.7 MPG, I filled the tank to make sure; it was spot on, for the # of miles driven; believe it!
