So you blew away the EPA estimate for highway by 7 mpg for the FWD?!! Is that reading off the car or doing your own calc?
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.

Door to door a bit over 200 miles each way including city traffic Raleigh 45 & OIB 35/20mph at each end so thats 400 miles give or take round trip. Outside of Raleigh before the I95 crossing is 10 miles of construction in both directions that sucks. Makes or breaks any high average. In OIB use the beach buggies & leave the car parked.
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.

I would believe 30.7 over 36.7 mpg any day!
Everyone's dividing the miles driven (trip odometer reset every gas fill up) by the actual gallons replenished according to the pump/receipt, right?

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 ?
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.

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

My cars computer has short and long term memory. The short term automatically resets each day if you do nothing to it, the long term you have to reset it yourself. Both show time driven (amount of time car has been running), ave speed, cumulative miles since reset and mpg I noticed last week running around that it had hit exactly 60 mins just by chance. The average speed and miles driven were spot on. I will take those figures over the fill the tank and then dividing the miles driven by gallons bought. I am too lazy to bother with that. Years back I tried that a few times and it was always pretty much the same as the car calculated.

The ones reporting that I have seen have been a bit on the low side but it's on rated 19/25 (surprising low considering the outgoing V6 was 20/29 and I never got below 21 driving and usually a few miles higher not hitting the highway in my aspec. Hopefully they get less thirsty when broken in. MPG is one of those areas the type S is behind in. Not sure what it is, when I got my S5 i was really surprised how good it was on gas while being so much quicker and powerful than my 18 v6 sh-awd aspec. The gains were balanced out as the 2018 was fine on regular gas and now I have to buy from top-tier stations and get premium only.

Well the way I look at it if I drive 200 & a few miles from full & put in 6 gallons or so every time the mileage on the cars counter must be pretty close. Will say its not as good as C&D got on the heavier M340 with the same engine but equal to or better than the EPA one.
