In a world where performance cars are becoming heavier and more complex, Toyota’s GRMN Yaris breaks the mold. A true enthusiast’s machine, this ultra-lightweight, track-focused hatchback is the most extreme evolution of the GR Yaris — a car already revered in the hot hatch world.
Engineered by Gazoo Racing’s Masters of Nürburgring (hence the “GRMN” name), the GRMN Yaris is not merely a faster variant — it’s a completely reimagined performance car with racing-grade upgrades, serious weight reduction, and rare exclusivity. In this article, we dive deep into what makes the GRMN Yaris a lightweight track monster, explore its technical highlights, and understand why it’s one of the most exciting modern Toyotas ever built.
Born for the Track: The GRMN Philosophy
The GRMN badge stands for Gazoo Racing Meister of Nürburgring, a title reserved only for the most track-focused Toyota models. Previous GRMN models — like the GRMN iQ, GRMN Vitz, and GRMN Mark X — have all shared a philosophy rooted in motorsport: less weight, more grip, and sharper handling.
For the GRMN Yaris, Toyota applied insights learned directly from Japan’s Super Taikyu racing series, where the GR Yaris has competed in endurance events. The car is more than just a step above the GR Yaris — it’s a machine that feels like it came straight off the pit lane.
Key Performance Enhancements
Let’s break down the main upgrades that make the GRMN Yaris so extreme compared to the standard GR Yaris.
1. Weight Reduction
Toyota didn’t hold back in making the GRMN Yaris lighter. Nearly 20 kg (44 lbs) was shaved off thanks to:
- Removal of rear seats
- Use of carbon fiber-reinforced plastic (CFRP) for the hood, roof, and rear wing
- Replacing standard glass with lighter materials
- Smaller and more focused interior trim
This weight reduction has a dramatic impact on acceleration, cornering, and braking.
2. Reinforced Body Structure
The body rigidity of the GRMN Yaris has been increased by 10% compared to the base GR Yaris through:
- Additional spot welds
- More structural adhesive
- Reinforced underbody and engine bay mounts
This stiffer chassis gives the GRMN Yaris racing car-level feedback in tight corners and high-speed maneuvers.
3. Close-Ratio Transmission
Instead of using a standard GR Yaris transmission, Toyota installed a close-ratio 6-speed manual gearbox with low final gearing, allowing for:
- Faster acceleration in lower gears
- Quicker throttle response
- Better power delivery for track driving
Additionally, a mechanical limited-slip differential is added to both axles (front and rear), ensuring even power distribution in corners.
4. Improved Aerodynamics
The Circuit Package features a large carbon fiber rear spoiler, side skirts, and a unique front splitter. All these components increase downforce while maintaining balance and stability at high speeds.
Meanwhile, the Rally Package leans into gravel rally performance, swapping out some aero parts for underbody protection, rally suspension, and roll cage-ready mounts.
5. Suspension and Brakes
Toyota worked closely with Bilstein to develop an exclusive GRMN coilover suspension. Additional tuning includes:
- Adjustable dampers (Circuit Package)
- Lower ride height (by 10 mm)
- Wider track for better stance and grip
The brakes are also upgraded, with:
- 18-inch ventilated brake discs
- Monoblock calipers
- Enhanced brake cooling

Inside the Cabin: Driver-Focused Minimalism
Step inside the GRMN Yaris and you’re immediately greeted with a no-frills, motorsport environment.
- Alcantara-wrapped bucket seats hold you tight during cornering.
- The rear seats are deleted, with a strut brace in their place to improve rigidity.
- Digital gauges emphasize gear position, lap times, and engine data.
- Trim and plastics are simplified to save weight, while maintaining a premium motorsport aesthetic.
The steering wheel, shifter, and pedals are all race-spec — delivering tactile feedback that encourages spirited driving.
Two Editions: Circuit vs Rally
Toyota split the GRMN Yaris into two distinct configurations to cater to different driving environments.
Circuit Package: For Asphalt Racers
This version features:
- Carbon fiber rear wing and roof
- 18-inch BBS forged wheels
- Low-profile Michelin Pilot Sport 4S tires
- Bilstein dampers
- Aero splitters and side skirts
It’s ideal for track day enthusiasts, offering sharp turn-in, high-speed cornering confidence, and incredible braking.
Rally Package: For Dirt and Gravel Fans
The rally variant keeps things grounded with:
- Gravel-spec suspension
- Guard plates underbody
- Shock-resistant construction
- Enhanced wheel well clearance
This model pays tribute to Toyota’s WRC pedigree, perfect for rough roads and rally stages.
Production & Exclusivity
Only 500 units of the GRMN Yaris were built, all for the Japanese domestic market. Within that:
- 350 were fitted with the Circuit Package
- 150 came with the Rally Package
Toyota used a lottery system to allocate purchases due to overwhelming demand, and all units sold out almost instantly.
Why the GRMN Yaris Matters in 2025
Amid tightening emissions regulations, rising EV adoption, and increasing vehicle automation, the GRMN Yaris is a love letter to analog driving.
- Manual transmission
- Turbocharged 3-cylinder engine
- Mechanical LSDs
- No driver aids interfering with your control
It is the anti-EV performance car, created in an era where such vehicles are disappearing. Toyota’s decision to develop this halo product highlights its commitment to enthusiasts — and keeps the spirit of motorsport alive in the road car world.
Collector’s Appeal & Resale Value
Given its extreme rarity, factory upgrades, and motorsport credentials, the GRMN Yaris is already commanding high premiums in the used market. In Japan, resale values have doubled or tripled in some cases.
It’s expected that:
- Less than 10% of the 500 cars will ever leave Japan
- Many will be preserved as collectibles
- Others will be used in grassroots motorsport events and rallies
Owning a GRMN Yaris today is like owning a modern-day homologation special, akin to Group B legends of the past.
Driving Impressions
Journalists and reviewers who got behind the wheel praised the car’s:
- Immediate throttle response
- Surgical steering accuracy
- Track-ready suspension tuning
- Raw, unfiltered sound from the exhaust
The manual shifter is precise, and the power-to-weight ratio gives the car a playful, aggressive character that rewards skilled drivers.
One reviewer from Japan’s Best Motoring summed it up as:
“The GRMN Yaris doesn’t just feel like a road car tuned for track — it feels like a race car with license plates.”
GRMN Yaris vs the Competition
The hot hatch and compact performance market includes some powerful competitors. Here’s how the GRMN Yaris stacks up:
| Model | Engine | Power | Weight | Transmission | AWD/2WD |
|---|---|---|---|---|---|
| Toyota GRMN Yaris | 1.6L Turbo I3 | 268 hp | ~1,250 kg | 6MT | AWD |
| Honda Civic Type R FL5 | 2.0L Turbo I4 | 315 hp | ~1,430 kg | 6MT | FWD |
| Hyundai i20 N Rallye | 1.6L Turbo I4 | 204 hp | ~1,210 kg | 6MT | FWD |
| Renault Clio Rally R3T | 1.3L Turbo I4 | 260 hp | ~1,200 kg | Sequential | FWD |
While others may have more power or clever tech, none offer the same lightweight, AWD, and motorsport-grade build that the GRMN Yaris delivers.
Conclusion: A Lightweight Legend is Born
The Toyota GRMN Yaris is a masterpiece of performance engineering. It’s not just a fast hatchback, but a purpose-built track weapon that exists outside the usual automotive trends. With its rarity, focused upgrades, and uncompromising design, it deserves its place among the most legendary limited-run Toyotas of all time.
Whether you’re a track junkie, a Toyota enthusiast, or a collector of modern classics, the GRMN Yaris is a car that stirs the soul — and reminds us why we fell in love with driving in the first place.
