Does anyone actually get the posted 22/24 mpg?

[Kevin]

I just hit 2,000 miles:

• First 500 miles: 24.2 MPG
• Next 500 miles: 25.1 MPG
• Next 1,000 miles: 23.0 MPG
  • I suspect this drop has to do with winter blend fuel, cold temps and some driving on snowy roads, which happens to every car in Minnesota during the winter.

This is on a 1958 with stock 18" Yokohama 245/70R18 tires and no roof rack. Mostly easy highway commuting miles. I've been taking it easy with the new engine, but not hypermiling.

Probably the biggest advantage to the 245/70R18 tires.. improved fuel economy.. but I don’t think I will downsize Miss Daisy’s Michelins.

Interesting, Why do you think that - lighter weight?

Yes, but there is definitely a technique to it. As a driver, you need to take advantage of the hybrid system to gently bring it up to speed, stay in the target zone of 1,500 rpms, and slow down using the regenerative braking, and start/stop engine pausing. The vehicle provides many aids to help you do this including the dash gauges, your drive pulse app rating, and the Battlestar Galactica sound effects.

But let's be honest. The LC hybrid is a blast to drive through town, in traffic, and around suburban obstacles. Its driving position, visibility, manueverability, and zippy fun factor create a constant tempation to suck that average MPH from 23 down to 18.

never gotten over 19-21 mpg since day 1 August, 2024. Mostly 18/19mpg

I got a slight decrease adding to 275 tires in a pretty significant jump up after the first oil change at 2000 miles. Now at 6000 miles and I’m probably 75% low speed Highway traffic and 25% in town with a daily 44 mile commute. I currently average 20.1 mpg. If it’s flat, I can easily get 23-24keeping it at 68 mph. If you push that to 80 drops to 17-18.

That, and a smaller diameter tire is easier to ‘spin up’, or so I have heard.

Less rolling resistance

That, and a smaller diameter tire is easier to ‘spin up’, or so I have heard.

1. lighter weight

2. Less mass requiring less inertia

3. less friction due to smaller contact patch

4. better aerodynamics if narrower.

However there is definitely a point where tires get too small and things go the other way where the gearing pushes engine rpm higher to maintain the same speed and mpg actually decreases

I’ve got 7500 miles on my LC LC and I average about 21 mpg with 50/50 city/highway. Almost always Eco mode. Regular gas mostly.

Has anyone tested and noted the difference between driving in Eco vs Normal?

ie: the exact same commute/driving style for an entire tank in both modes, hand-calculating MPG?

I did a full tank on normal then a full tank on eco. Both turned up a 17.2 average. I suspect the eco would've been slightly better maybe around 17.5 but the weather was colder on eco mode. If I pay attention to it I can get around 18. I am almost all city miles. commute to work is just under 5 miles with only 2-3 of those on stop and go hwy. I was getting 12 MPG in my 2020 ram rebel 5.7 that advertised 19 mpg combined. I also test drove the GX550 and tried to do a usual mix of driving, also turned up 12 mpg.

Given that most cars now implementing turbos with a 4 or 6 cylinder, I am very happy with my ~17.5 mpg on my LC. If i went from my 87 octane truck to a GX getting the same 12 MPG AND having to use premium... that would've been a double gut punch.

*This is with front wheel well air dams removed, ditch lights and side lights on roof rack.

I have decided you all drive like maniacs. This is generally all down hill from Ontario, CA to the beach, socal commute traffic, not bad but cant drive 80 . I usually get in the low 20's on my way to the office, but keep forgetting to take a picture

Looks like you unlocked your true MPG potential. Come join us in the real MPG discussion thread!

yeah im gonna need a full length video of you driving this trip lol I don't believe it. Especially with the first edition roof rack which I also have. I have always thought the roof rack kept my hwy mpg on a flat surface limited to maybe 19 or 20 MPG at best (60 or 65 MPH). have taken a lot of road trips and 100+ miles is never above 20. some in city longer transits i might get 24 or 25.

Like i said, all slightly downhill, and when in 30-40 MPH traffic, if you dont jam on the gas peddle it stays in EV mode and the millage shoots up. There is generally less traffic on the way to the office, usually more like 65-70 MPH an rarely do you see it stay in EV mode.
