A few years ago, Subaru killed off the beloved WRX STI. This year, to help appease the brand's rally fans, there is a new higher performance WRX called the WRX TR. To see how close it comes to being an STI replacement, we've pitted it against the most STI-like car currently on sale, the Toyota GR Corolla.

I test drove both cars, and the base WRX felt better in every way—shifting, handling, and braking. I think the WRX has a slightly wider wheelbase. I paid $28k MSRP, while the GR was almost $50k. The WRX looks sportier, whereas the Corolla resembles a Yaris, which I find unattractive.

In terms of performance, while the GR Corolla might be faster or have more horsepower than a base WRX, the WRX can be upgraded. With the price difference between the $28k WRX and the $50k GR, there are many options to increase the WRX’s horsepower.

The GR Corolla has 3 cylinders, which might not bother some people, but I feel there’s a stigma with 3-cylinder cars. The WRX has more displacement than the GR, with 49.9% more—4 cylinders versus 3.

Another issue with the GR is its horsepower-to-liter ratio. It has 100hp per cylinder, which, in my mind, isn’t reliable.
In my eyes GR is something toyota slapped together, to make quick buck. Restrictive warrenty. Engine thats already maxed out.

I think you drove the wrong car...

Nah. The G16E-GTS is Toyota's first purpose-built performance engine in decades. The FA24 just... isn't.

Demonstrably false. The G16E-GTS was designed for 100hp per cylinder and the FA24F isn't.

The GR Corolla is a proper performance machine. The WRX has gotten fat, soft, and soldiers on with a driveline that was old and tired in 1999.

I'm an enormous fan of the G16E-GTS. It's proof that Toyota can still design engines like Toyota's golden era 2JZ-GTE and 3S-GTE.

The G16 is pretty simple (unlike an EA888), but the offset crank is trick. The block is really rigid, the 9 (3 per cylinder!) oil squirters help keep piston temps manageable and the dual injection strategy (D4-S) should be standard on all cars. It's built to handle boost and, as you'd expect from a Toyota, it's proving to be extremely reliable. The heads have been shown to produce great flow AND tumble which is tough to achieve simultaneously.

The only "downside" is that it returns much worse fuel economy than a 1.6L 3 cylinder probably should - a worthy STI successor after all.

Don't get me wrong, the FA24F was a necessary step for Subaru, but it is certainly NOT a performance engine.

Toyota’s warranty service has been disappointing. I’ve heard of several new Tundras experiencing engine failures. Many manufacturers are facing production issues. While the G16E-GTS engine is impressive, producing 300hp from a 3-cylinder, its design prioritizes cost reduction and environmental compliance over long-term reliability. Toyota even offers free track time, which can void the warranty. A 2.0 or 2.1-liter 4-cylinder engine with 300hp would be more convincing.

As a car enthusiast, I value both performance and reliability. The FA24F isn’t a racing engine, but most enthusiasts don’t need one. My VB is my daily driver and won’t see the track. The 2.4-liter 4-cylinder strikes a good balance with 113hp per liter, offering performance without being extreme.

If the G16E-GTS is such a great platform, why not use a 4-cylinder version in the Supra instead of a BMW engine? It likely comes down to cost; developing a 3-cylinder is cheaper, and integrating BMW’s engine into the Supra is more economical.

The video clearly shows the WRX as a smoother street car. Strong engines aren’t always ideal for daily driving; they’re better suited for drag or track use. These engines last because they’re only used on weekends

Oh boy, you must be new to Subaru if you think that Subaru's warranty service is going to be an improvement on what you've shown above.

I'm sorry, this is still a red herring. Reliability and power handling are functions of design, not cylinder count.

The EJ25 is a glass shack compared to the G16E, and that has more displacement than the examples you've offered up.

I never not liked a v8 or v6 or straight 6. Always liked boxer engines, having a 67 beetle. A Honda N600 would beat the GR in looks lol 😂 even a type 1. I test drove the GR didn't like it and it 48k vs 28k for wrx. Decent 240z that was updated, that was a fun car. Ex-wife stole it and sold it. Divorced her for that lol. 50k+ your starting to get into some interesting cars...

I've been reading and re-reading the prices on modern cars and it makes me worry I am utterly out of touch.

Johnny Carson should do a monolog on the Tonight Show about it!

Cars are nearly a junkies bad habit with me. Beware of cars with enough torque to actually turn the globe and with enough horsepower to turn tires into melted smudges.

FWIW, I may be having an itch problem ... again.

I'm comming off a Veloster N which is much more comfortable than a GR. At even money, the N is way faster than the WRX and track ready. WRX is much more comfortable and my family will actually get in the back seat. With an engine tune, suspension, shifter parts, and brake pads, will be just as fast, same comfort, but more roomy; so about the same as a Civic R but all wheel drive. Too bad you have to void your warranty to make the car run at what imo, should be the power from the factory. Eyesight and Starlink suck the big one and the shifter is same old piece of crap. But even if I had the extra $30k for an Acura R or Lexus IS 350 F, neither has all wheel drive. No one would buy one, but a manual IS 500 would be something to pine about!

My 2022 WRX LIMITED is the BEST all around EVERYDAY car. Especially me living in Ohio where I'm hit with all 4 seasons with rough streets and highways. I have all that I need for family needs and travel, with a truck to store what I don't want seen. I know that my WRX is not a DRAG RACING car!!! It's a QUICK, with good speed (so far I've got up to 142 while in 5th), tight handling, gear shift is firm and just a TOUGH built car. I'm not the Tuner type of guy. My WRX is stocked and I'm good with that. Especially when I was T-Boned in my 2017 WRX at 30 mph, which was totaled and I had 160K miles on the car and got 21K in insurance for my new 2022. How, because I didn't tune my car. Also, what is a car without good tires? I love using Continental Extreme Contact DWS. Excellent All Year Round Performance Tires. Again, Subaru is a tough car. WRX's are made for people, male or female, who at times have a BAD ATTITUDE!! I'll chase down any car of my caliber, if not pass up!! I ain't scared of snow, mud or gravel. I'll out maneuver any HEMI, FWD and RWD!! Cuz I got the F'n attitude to do it. LMBO!!

If you're after a practical and eco-conscious vehicle, the RAV4 Plug-in Hybrid from toyota-odessa.com.ua/models/rav4-plug-in-hybrid could be the perfect fit. I’ve been eyeing it for a while, and it ticks all the boxes for both tech and practicality. With its electric driving capability, you can easily manage your daily errands without using any petrol. The spacious interior and advanced safety features really stand out. I can see this being a fantastic option for families looking for an efficient and versatile ride. Definitely check it out!
