Just want to know of those of you who have taken delivery, how do you find the posted MPG or L/100km as compared to real driving conditions?

my fuelly wont be a good presentation since i have only been using it for congested rush hour driving, my MPG will be horrible and drag down the average

Its friday today n the roads in toronto are not as congested during the morning drive to work, SH-AWD V6, same route, 75% city driving 25% highway, econ mode, lots of hypermilling n coasting whenever possible (basically driving like a hybrid), easy on the brakes whenever possible at a red light (rolling stop), engine idle stop whenever possible, outside temp is around 7-9C, drove for around 45mins, max speed just below 60mph, A/C off 95% of the time, getting 9L/100km for my trip. 10L/100km city driving before entering the highway which dropped to the 9L/100km total

engine idle stop does not work for the first 5 mins of driving from a "cold boot", so i suspect the engine needs to warm up first before the idle stop can kick in. which also means when we reach sub-freezing temperatures this function may not work as frequently (if at all) as in the summer or even now.

so going forward, i will most likely leave the car under ECON mode while commuting or normal driving, certainly will not need the full 290HP on the engine in those cases. even though gas prices are temporarily dropping, it still ain't cheap to fill up the TLX for almost a hundred bucks. will put it in SPORT mode if i feel like speeding beyond 75mph or need to accelerate entering a highway ramp to get to highway speeds (but even then ECON is probably sufficient)

i would say under normal to slightly desirable conditions, the advertised city driving MPG is certainly achievable, if not better. canadian models are rated at 11.2L/100km for city driving and overall i am getting around that range (11L/100km or so), or even better if i am more conscious on applying fuel-saving driving techniques and if we are driving in warmer temperatures where the engine warms up much faster.

for this reason i am placing my vote on "better than advertised". may get even better if in the summer (A/C usage may affect mileage though)

i have yet to take long road trips to test crusing highway MPG, but i personally care about city MPG more than highway MPG

I drive from Ajax to Aurora in Ontario and today my average is 7.0 liter/100km or 34 miles per gallon. Only had the car since Tuesday and i drive avg 100kms per day both ways to work. The 7.0/100km is in all sport mode too. Keep in mind i drive avg speeds of 60km to 100km back roads. Decent vs my previous 4gen TL. My best in 4gen TL was 8.3/100km few times and that is with nursing the pedal like a granny. Avg is 9.5 to 10.5/100km 4gen TL.

i read somewhere that driving any faster than 100km/h or 60mph on the highway will increase your MPG and the extra gas use is not worth the extra speed due to drag

did a bit of highway-only driving just before midnight. road is clear, all cars are driving at their limit, no cruise control, same 'ol driving style (ECON mode with AC off, as much coasting as possible), got 7.6L/100km on my short trip, which is slightly lower than the rated 7.8L/100km, so advertised MPGs are certainly achievable or better for both city driving and highway driving depending on your driving habits and style

i also ran my gas tank empty, didnt fuel up until there's only 5% left, with 50km range left. could have tried to milk that remaining 50km/5% fuel but dont want to risk it since it's a brand new car

also looks like the trip computer is a bit off in terms of mileage, i finished my tank of gas and after a fuel-up my "raw calculation" mileage is 10.4L/100km (amount of gas fueled up divided by distance traveled), while the trip computer says 10.0L/100km

guess i am going to start using fuelly, but no images are allowed in signatures on this forum?
 
#57 ·
fueled again just now, with only 12% fuel left, engine light not on yet. trip computer says 9.9L/100km, though fuelly/raw calculation gives me 10.3L/100km

so it looks like the trip computer is off by 0.4L/100km pretty much consistently, which i guess is a good thing since my lexus fluctuates alot on the MPG and for the TLX i can just subtract 0.4L to get the real MPG

this tank was using 89 octane fuel, and got pretty much the same mileage. though i should be able to do better since i wasted quite abit of gas idling and digging through vehicle settings for idle stop stuff (which requires you to be idling on park) and testing the tire repair kit for pumping air into the tires, which requires the cigarette lighter plug and boy does it eat alot of power; you really need to have the car turned on and running.

my next tank is filled up with 91 and letsee how it goes, and i need to seriously stop playing around with settings when the car is idling. but i feel that long term i will be using either 89 or 91, depending on gas prices

Fuel consumption (city)

2nd tank. 91 octane. I achieved 10.4 l/100 km or 22.6 M/US G or 27.16 M/ Imp G. Mostly city driving. Commute to work is about 25 km one way with max speed of 80 and a total of about 15 traffic lights and 3 stop signs. This is slightly better than shown on Acura site. My past experience with my 2004 TSX was significantly better on the highway than advertised ...but who is complaining

:D

The car has only over 1000 km on it but the temperature has been dropping which negatively affect gas consumption. I'll keep you posted.

Better than EPA

With 6k miles I am getting between 37 to 40 mpg with the 2.4 mainly highway driving, normal IDS. Recent road trip was disappointing as I fought head and cross winds reducing mpg to around 30 for the second half of the trip. Now if they could fix the transmission issue we'd have something. When cold it is very jerky on shitfs

6,000 miles already!? :eek:

I thought I had a lot at nearly 3,700 miles.

Impressive V6 MPG



We are impressed that after 2,000 miles our V6 averages 27.5 mpg to work and back at about 45 to 55 miles per hour. Last month I filled it up with premium and did the freeway to the Denver airport and back. On the way back about 65 miles per hour, it was averaging an astounding 39.4 mpg. That was easy cruising with light traffic but still amazing for a 3500 lb car with 290 horsepower. The real test will be with passengers and luggage, going over the Rockies and the 11,000 foot passes. That is a test of any car.

V6 AWS mixed driving town, highway and winding Texas hill country roads. 1,000+ miles on odometer. 93 octane gas. 65 mph on highway and less in town and in the hills. Air on most of the time. Most driving in econ and normal modes. Averaging approx. 32.5. Expect better with more miles. Have used Sport and Sport+ a little and it was lots of fun. Will use more when better broken in. I loved my Mustang GT I traded for the TLX but I have no regrets. The Mustang was slightly quicker but the TLX holds the hilly roads better. Love the car. Very comfortable and fun to drive!

Welcome to the Forum!



Welcome to the Forum! I see this is your first post.

Glad you are happy with your TLX. What color and how many cylinders did you get?

I found I got excellent mileage in Sports mode. One trip to dinner 45 miles away netted me 38.8 MPG. I tried to drive normal, but a couple times I hit the pedal a bit too much. Had AC on and drove on flat roads.

I hardly ever take it out of Sports mode. If I get stuck in bumper to bumper traffic I try to remember to go Econo. :)

would be nice to tell us where you are located

MPG varies according alot of factors:

- weather (snow?)
- temperature (freezing temperatures?)
- driving habits (heavy on the pedals? no coasting?)
- traffic condition/congestion (stuck in traffic and idling for a long time)
- use of A/C
- try driving in ECON mode

Only had car for 10 days, drove 255 miles so far but was in idle for a long time while programming the car's functions. So my mileage so far is 24mpg with 93 octane gas. Was in Normal mode.
I did manage to get 32 mpg on a 50 mile trip on the parkway. Will do a 1100 mile trip in 3 weeks. I used to get 29-31 mpg on my 2012 TL Advance on a 1000 mile trip on #95 between FL & MD and 29-30 MPG on my 2003 TL "S".

Welcome to the Forum! Sorry I missed your first post.

As owners, I think we all understand about sitting in the car in park with the engine on while learning the new technology. Enjoy your new TLX.

It may be in your other post, but what model did you get of the TLX? :)
 
#73 ·
I can't speak to a specific split but I live in a very hilly/mountainous area and my combined with my estimate of 80/20 split is 10.3 l/100km or about 24mpg most;y in sport but some in normal mode, which I am very happy with. I know early on I drove it very hard for half a tank and got 13.7 but that was just because I really wanted to test the car's acceleration and cornering performance.

I agree. The first couple of tanks are fairly useless to record fuel economy if you are like most TLX drivers. Besides testing the cars aggressively in Sport or Sport+ modes, you will probably sit in idle while learning the new technology or showing the car to friends and family. :)

My average fuel economy has been spot on the advertised mileage. I'm averaging about 27 in the city (I've got a 2 mile stretch on my 5 mile commute to work that is no lights and 45 MPH speed limit) and 35 on the highway.

I'm in North Carolina, and we WERE having a pretty mild winter up until today! I have no idea whether the A/C is on. Temp in the car is normally set at 78, and the windows are clear so I would assume so. Pretty light traffic, and I'm easy on the pedals.

ECON mode is a NO GO. It's so sluggish and feels like wading through mud. My car is normally in Sport or Sport+ when I want to keep it out of 7th when I'm doing 45 lol. I have it set to default to Sport whenever I start the car.
