GR Corolla Fuel Efficiency Comparison

11316 Views 70 Replies 42 Participants Last post by  KanmuriDavid
Haven't seen many people talk about this part of the new GRC much, and honestly, not a priority for most people I would imagine. Still fun to see how it compares to its competitors though if you want to see which one really gives the most bang (or most mile) for your buck.

GR Corolla : 21 (city) / 28 (highway) / 24 (combined)

All values below are for the manual versions of the cars.

2022 Golf R : 23/30/26
2021 WRX STI : 17/22/19
2021 Civic Type R : 22/28/25

2022 GR86 : 20/27/23
2023 Golf GTI : 24/32/27
2022 WRX : 19/26/22
2023 Civic Si : 27/37/31

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

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!

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

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.

That's what I was thinking too, maybe 30 ish going 65 on a flat road. Either way high 20s is nice

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.

Some might have "Premium recommended" rather than required, but yes, all the cars I listed should be on premium.

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...

Small high compression engine being force fed 25+psi of boost? Yes, premium is required. But go ahead and put in 87 octane into your GRC, who am I to tell you otherwise?

Totally agree - putting anything but premium fuel is just asking for trouble. I'm glad I get 93 up here in Ohio.

Even if the GRC gets only 24 mpg combined with premium, it'll probably end up being about the same cost to drive as my Wrangler (which is rated 17/23/19 but I typically get 21-22 mpg with my driving). Assuming I'll be toward the highway rating of 28 mpg I'm almost guaranteed to have lower running costs than the Jeep or at least it's so close it doesn't matter.

The mileage of the WRX (and STI, especially) has always been absolute trash. My wife has a '17 Forester XT with the CVT and she rarely gets above 25 mpg but it's also a much larger box on wheel vs. the WRX. I really don't know how the WRX is so bad on fuel.
