I remember at some point in the review @jamesThrottleHouse said something along the lines of 30MPG while he was using it prepping for the review

 

Yeah, he said ~7L/100kms which is 30ish mpg. Probably depends greatly on the weight of your right foot.

 

I feel like Toyota undersells their MPG. Our 86 got 25.5mpg on a full tank INCLUDING a track event. I got 29 when driving it nice.

 

Honestly one of the big reasons I'm looking at the GRC/CTR over the GR86 is because they have the same mpg but even more practicality and more power (just that the car itself is more expensive).

Considering the GR86's size, weight and power I wish its MPG was closer to the Civic Si's.

 

how does it compare to say.. a 98 civic LX? with a k20 swapped motor!

 

Fill it up before hitting the touge

 

As long as it's better than my FJ 😂

 

I wonder what the range is like on it if you are highway cruising. I am going to have to make a few long trips in it and if the MPG is understated I am going to be pretty happy

 

I’m sure we can get 28 mpg, maybe squeeze out a 30 mpg.

 

Do they all require premium?

 

It's running 25lbs of boost. Yes.
Misunderstood, not sure if all the cars listed do.

 

If it’s anything like the tundra, we’ll see a wide spread depending on driving habits. I get anywhere from 10-16mpg in the truck depending on how often I hit the express lanes.

 

I saw a review and they said I believe it was 31 highway and 24 city

 

I am happy to see these numbers. I was hoping that moving from my Taco it would be a wash in overall dollars per mile going to premium. I was afraid they would be closer to Subaru numbers. those numbers in 2022 are really disappointing for the WRX. and to think the FA is an IMPROVEMENT over the EJ is just sad. I am sure it has to do with the characteristics of the unusual drivetrain they use but still...

 

Low quality gas=knock=

 

Looks like the most fuel efficient choice (GTI) is 87 recommended. Actually the 2nd most efficient, the most efficient (civic SI) 91 is recommended.

 

The GRC also has a 13.2 gallon fuel tank. Not the biggest. Still will allow an OK range between fill-ups, if not great.

2023 Toyota GR Corolla - Toyota USA Newsroom

It’s official: The powerful, stylish and agile hot hatch U.S. drivers are looking for is on its way, the first-ever 2023 GR Corolla. With the detail-obsessed TOYOTA GAZOO Racing team at the helm, and master driver Akio Toyoda, a.k.a. Morizo, […]

I'll give some perspective here. I've got a Matrix XRS from '04 that was rated 22/29 MPG while also having a 13.2 gallon fuel tank. With my more "lead foot" driving it gets maybe 250 mile usable range? I don't think I've gone over 300 though even when babying it. Most of my driving is city with a bit of freeway on the way to work. I'm from Hawaii so we don't exactly have long straightaways to get the best MPG runs lol.

 

i think the most relevant comparison is smiles/gal

 

That's how I measure the mpg in my 30 year old 5 liter V8, because I'm scared to know the real numbers.

I'm pretty happy with the MPG numbers for the GRC, if they are indeed underrated (for non-enthusiastic driving) then I'll be even happier.

 

This is one of the problems with the GRC.

Everyone is looking at 300Hp but not looking at what it takes to get that out of a 1.6 engine. you need like 23-26psi of boost where as if it was a 2 litre its only 15-17psi.

If you want the power it uses more fuel end of story and AWD uses even more fuel than FWD because of the increase transmission losses, thats just the way it is.

The GRC is going to be a 98 only fuel over here at those type of boost levels if you are planning to drive it hard.

I disagree, Civic Type R has basically the same fuel efficiency with a bigger motor and only FWD. The small motor helped offset the AWD in the GRC fuel efficiency wise. GRC also has the same fuel efficiency as the GR86 thats only rear wheel drive and has significantly less HP.

 

I can comment on the CTR. I own a stock ‘18. My commute is mostly mixed driving with 75% country back roads and 20% highway and 5% city. I average pretty much always 28 mpg. On the few highway trips I’ve taken it’s 33 mpg. Worst ever mileage was 24 (it’s got 18k total miles on it now I bought it new).
Edit: worst ever mileage was about 11! But that was at a track day. The 24 mpg was worst driving it on the roads.

 

Stay out of boost, short shift, feather the throttle, and the GR Corolla will be fine.

 

Not sure if anyone else caught the MPG rating in the last Press Release but 21mpg city, 28mpg highway, 24mpg combined.
I know the little triple is strung out, but it’s not great :/

For comparison:
2022 Corolla Hatchback 2.0L NA 4 (6MT, FWD): 28/36/31
2022 Mini Cooper 4dr 1.5L Turbo 3 (6MT, FWD): 27/37/31
2022 Ford Bronco Sport 1.5L Turbo 3 (8AT, AWD): 25/28/26
2022 Mini JCW Clubman All4 2.0L Turbo 4 (8AT, AWD): 23/31/26

 

send it

 

Yeah that's a little disappointing but those drivechain losses are gonna get ya. Would love to see an MPG breakdown between the different torque splits and drive modes.

 

Lol, not nearly bad enough to discourage anyone. I'm grateful they got the performance out of the engine that they did, and will happily give up 3-5mpg for it.

 

way better than evo 9, focus rs, etc etc

EDIT: oh and veloster n only gets 25 despite being fwd

 

I don't think beating 15 year old cars are the only thing this car should be aspiring to 😅

But yeah, the Veloster N tho, yikes.


Overall, somewhat disappointing but in line (3) with all the other cars in its class, if not a little better.

 

Lol the 2023 BRZ/GR86 are rated at 21/30 with a 2.4L NA boxer engine. The curb weight and AWD drivetrain losses basically negate the fuel economy benefits of having a smaller turbo engine.

 

Luckily for the people who care about MPG's, Prius' and Camry's are sold on the same lot.

I doubt my GRC will even break into the 20's 🤣

Mine either. And it will be modded so it gets a lot worse MPG. Not my daily driver. That’s what the regular Corolla hatch is for!

 

Just as a FWIW: I don’t really care about MPG…it’s not going to be a door stop for me.

But my 7,000lb truck with 6.4L gas engine and 35s gets 12-13mpg combined(actual, it’s not have EPA rating since it’s a 3/4 ton). You’d think the MPG on a car that weighs half as much and 1/4 the displacement could do better than just 2x MPG.

 

It's not what you drive, it's how you drive it.
Top Gear did a great comparison years ago. Prius went all out, M3 just had to keep up. M3 did way better in MPG.
