Why does the 2018 Fit in LX trim and CVT have such better mpg than the Sport, EX, or EX-L trims (33/40/36 vs 31/36/33)? Don't these all have the same drive train?

I'm interested in buying a 2018 Fit (my first) and was originally leaning towards one of the higher trim packages. But I'm a bit put off by the apparent mpg hit. Do 16" alloy wheels really hurt mpg that much?

 

cause only fat people drive the other ones.

aka u will get great mpg regardless

 

Have an 18 sport. Doing 36 city 40-42 hway

 

That seems very odd to me, sure the LX is a little lighter but not that much.

My 18 sport 6MT I am getting 38-40 in all city driving - very happy.

 

 

it is the weight, everything else is the same; but it's only a lab number, so many variables. don't stress out over it

 

I love how easy it is to get mpg up with the GK. It wants to conserve gas. Same driving style with my old GE and I was only doing 30-32 city/hwy combined. I'm at 38 mpg combined with the GK rite now on my 2nd fill up.

 

sounds about right. i got 42mpg without even trying when i used it for a week.

 

This. The sunroof adds weight which affects EPA calculations but I love it. I drive it like a sports car around town and get 30-32 mpg... when I do take highway trips it gets right at 40. And I'm a fat people.

 

16" alloys weigh 40lbs/wheel while the steelies weight 35lbs/wheel. In my experience, heavier wheels always hurt fuel economy and acceleration. I can feel it since I used the stock 35lbs steelies, 35lbs aftermarket alloys and also the OE 40lbs ones. They feel heavier in hand too. A lot of weight to turn around all the time. On the hwy I noticed literally no difference; but city driving, that's where the 40pounders hit you.

 

All good points, but the best one is: The driver is a larger variable than just about anything on the vehicle trims. Drive like someone who just bought a car with "sport" in the title and results will follow!

 

thought u were making fun of my “gallon pack” economy size belly , fujisawa..must be nice to have a 6 pack.

 

I just put about 1400 miles (in the last 6 days) on my 18-EX 6 speed averaged 40.7 mpg. My last leg of 315 miles on the expressway averaged 42 mpg.

 

i think if u go 60-65mph max you can get more like 47mpg..

 

Hahaha, no ... driving behavior. I mean I guess at some point there starts to be a difference based on driver weight but, aside from an F1 driver I don't think it's a big impact for the rest of us.

Also pro tip, never point out to your passengers that they are >5% of the car's weight. Nobody wins.

 

My dealer had a pretty detailed explanation, explaining the LX with CVT does not have paddles and if there are paddles, part of the test averages would require the use of the paddles. I'm not sure to the truth of it.

As for my 11,000 miles driving in my 2018 EX with sunroof and receiver hitch (small weight and aerodynamic change). People like to know the interstate mileage. Most or almost all of my interstate fits the following format:

• Fully loaded. Fit is rated at 800 pounds of stuff, including humans. I load to about 800-850.
• Airbags in the back with 15-18psi
• 2 bicycles on the back rack (one bike loses about 2-3mpg, two bikes knocks off 4mpg)
• Headwinds make a bigger difference than anything
• Interstate speeds around 75-77 in this CVT car. Previous 2015 6spd, speeds around 71-72mph.
• Fuel economy calculated with calculator, not the dash. Dash is pretty accurate (within .2) if using quality, ethanol free, premium.
• Premium does not pay off for fuel economy, but the calculator is proof that I always get 2-3mpg better with really good fuel.

Typical highway fuel economy 34-37. You can somewhat assume the fluctuation caused by headwind, mountains, and potential odd traffic behavior.

I mentioned my previous 15' 6spd car because I get about the same numbers, but drive about 5mph faster on the interstate. The 6spd car would lose MPG's quickly as you go up over 70.

2 people, empty care, cruising on the interstate at 72, no problem to bank 40+ all day long.

 

hahaha!
