Short drives where the engine doesn't warm up are bad for any internal combustion engine fuel consumption. It would be worse for a non-hybrid.

 

my 2024 rx350 AWD gets 14mpg in new york traffic highway about 25/27 1250 miles on odometer hope it gets better i also do a start up to warm the car.

 

Don’t do the warm up… just give it like 10 seconds and go… that warm up kills a lot of your gas if you’re doing short trips.

 

Not sure why I don't get that kind of mileage. I have a new 2024 RX350 AWD. I drove from Orange County to Las Vegas and back in "ECO" with 91 octane fuel, 70/75mph for a total of 490 miles highway. I got 21.9mpg. My 2016 RX on 86 octane always got 24mpg or better on same trip. I now have 1100 miles on the car. Now I have to use gas that is 30 cents more per gallon and a 4 cylinder car that gets a minimum of 2mpg less. Anyone have any ideas?

 

With 1100 miles only engine is still in break-in period, so fuel economy might not be your final.

The 2024 rx 350 and 2016 rx350 have similarly rated fuel economy.

The 2024 RX 350 is explicitly rated and published to use premium gas tough.

The only 2024 RX that uses regular gas is RX 350h now.

 

getting 28 mpg consistently on highway trips, fine by me.

 

2023 AWD RX350 F sport - 20.9 mpg. Its honestly worse than my 2017 RX350 FWD. My 2025 BMW X5 M Sport gives me much better mileage around the city. 24-25 mpg and it’s a V6.

 

Had it wrong. I was still on the trip milage originally set at the factory. Did a reset, and drove to Palm Springs and back. (about 200 mi). Got 28mpg. All is good

 

I drive about 60/40 highway/local streets. My 2023 RX350 with turbo ICE (2wd) is averaging about 26 MPG after about 11,000 miles.

 

I’m getting 16-17 combine on ECO mode

QUOTE=OCRaider;11515592]I have a non-hybrid AWD. It is supposed to get 21 MPG in city / 24 MPG combined (https://www.fueleconomy.gov/feg/Find...n=sbs&id=46233). However, I have been getting about 18-19 MPG combined. Does anyone else have a non-hybrid AWD and if so what is your MPG?

Can't tell why my MPG is low. Perhaps the car is still "new" (700 miles on it) and needs to break in? Note that I have the 21" wheels with correct air pressure, have been using premium fuel, and driving in normal (not Eco mode). I haven't been driving all that aggressively either.[/QUOTE]

 

24 non-hybrid. Normal mode city around 20-22 mag. On interstate, 27-30mpg. Average. I used eco mode for a long time, didn't like how the car drove. So now I just leave it in normal mode. Can't really say there's a difference, maybe 1 or so mpg.
It took a couple thousand to break in & give consistent MPG.

 

I do not understand why my mpg is so low. If I don’t drive on a highway it’s 15.5 which is ridiculous

 

What’s your current mileage on the car. Ppl saying sometimes mpg improving after 2000. I’m still under.

 

Give it at least to 2,000 miles. I didn't even measure mine until it got above that. Likely still breaking in with 700 miles. I do 70/30 city/highway and am getting 24 mpg. Just what I expected.

 

Also cold temps will lower mileage. My 350h average per tank dropped from the upper 30's to the mid to lower 30's when it got cold outside. Cold weather hurts any type car, hybrid, ICE or EV.
