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.

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!

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.

Dude from throttle house said he was averaging 31MPG HWY

 

[Jeonsa]

I wasn’t expecting it to sip fuel like a Yamaha 3 cylinder so I’m fine with it

 

[qtb007]

Seems perfectly reasonable, IMO. All those other 3 cylinders are not performance engines with performance AWD systems and sticky tires. It will likely do 30mpg highway if you drive with any sanity.

 

[surfwaxsmitty]

Honestly that’s great

I'm not going to be losing any, my 2012 GTI gets an average of about 24MPG as is. This will have 100,000 fewer miles, 100 more HP, and Dynamic Force injection. I hope the days of fouled plugs and excessive carbon build-up will be a thing of the past for me. I don't want to pull my intake manifold off anymore. 😂

Side note, does anybody have experience with dynamic force engines and how the direct and port injectors do at keeping the intake valves clean?

Looks like someone got PTSD from that modern VW lyf.

Jokes aside, port injection is typically working at idle and low rpm most of the time, but its operation is not absolutely fixed, the ECU will still switch between DI and PI as it sees fit.

Strange take considering my Dad's 6.2 Liter Denali gets better MPG then my Tacoma with its Highlander V6.

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 : 21/31/25
2023 Golf GTI : 24/32/27
2022 WRX : 19/26/22
2023 Civic Si : 27/37/31

Those numbers for the GR86 are for the automatic. The 6MT is rated at 20/27/23.

Oops, so you're right! I'll go edit that.

Not bad tbh considering full time 4wd and wide tires. It has to continuously slip the viscous coupling.

If I can muster the discipline I'll try to hypermile one tank full, see how much I can stretch it.

I know I'm being nitpicky, but I don't think its a viscous coupling. It is a wet clutch, but I think viscous coupling means its using hydraulic pressure to transfer the torque, not physical contact. The GRC as I understand is still a mechanical clutch pack, just running in a oil bath.

In either case you're paying a penalty in efficiency

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

Canadian gallon 20% larger..

I'm averaging 30 U.S. mpg on my commute to work and back.

How fast do you drive? I average 24mpg and go about 75 most the way.

I average about 60mph. No stop and go.

 

[dalegoat]

Track/sport mode first two tanks.
Tank 1 @ 21.8 mpg (229 miles traveled) [this one includes 9 miles on odo at pickup]
Tank 2 @ 24.7 mpg (240 miles traveled)
Mountain roades - easing out of break in @ about 500 miles.

I am already into tank 3. Tank 4 will be eco/60-40 to see difference.
