Do they all require premium?

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?

I believe they were asking about all the other cars the GRC were being compared to. The Civic Si for example is most definitely not running 25+ psi of boost and I believe it officially says "premium recommended" but not required. That being said... I definitely encourage running premium for all those cars.

I believe they were asking if all cars in the comparison use premium, just so we have a direct onene comparison.

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.

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'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.

 

[d15b7]

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.

 

[KanmuriDavid]

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

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.

 

[kazoobaru]

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

 

[rallycorolla]

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.

 

[DocRoc24]

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.

 

[wind_slash]

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.

 

[turb0]

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.

 

[A91supra]

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 🤣
