• Inspect your radiator fins on a monthly basis, particularly if you drive in dusty conditions.

• Always use a 50/50 mix of Toyota Super Long Life Coolant to ensure compatibility.

• Regularly monitor coolant temperature using the GR-Four monitor, especially during prolonged use.

Turbocharged Power Upgrades

If you’re considering performance upgrades, there are several safe modifications and warranty-friendly options to consider. This section will guide you through some of the most popular aftermarket enhancements.

Safe Aftermarket Modifications

Enhance your engine responsibly with these modifications:

• ECU remapping can boost output to around 310 HP, unlocking more potential.

• Install a high-flow air filter that acts as a drop-in replacement but allows your engine to breathe easier.

• Upgrade to performance exhaust systems that improve backpressure and sound.

• Consider an upgraded turbocharger wastegate to optimize boost management.

Warranty-Friendly Enhancements

These modifications are approved by the factory and can be safely integrated without voiding your warranty:

1. The GR Circuit Racing suspension kit for improved handling.

2. Factory-approved carbon fiber intake systems that blend performance with style.

3. A TRD oil cooler kit to maintain engine integrity under stress.

4. Enhanced OEM+ transmission mounts for smoother gear transitions.

Real-World Fuel Efficiency Tests

Discover how the Toyota Yaris GR Engine performs in various driving scenarios that matter to you as a driver in a hot climate:

Comparing Urban versus Highway Consumption

Numbers derived from tests in challenging conditions highlight impressive fuel management:

• Dubai city driving averages near 9.8 L/100km.

• Long highway journeys, such as those between major urban centers, can see consumption drop to 6.2 L/100km.

• Driving through mountainous or winding roads averages around 11.3 L/100km.

Key features that support these fuel efficiency numbers include:

• Cylinder deactivation technology that helps conserve fuel during steady cruising.

• A dedicated Eco mode which fine-tunes throttle response for reduced consumption.

• An auto start-stop system that can be disengaged with the touch of a button, giving you control where necessary.

2025 Reliability Improvements

Reliability is at the heart of every great engine. The 2025 upgrade of the Toyota Yaris GR Engine includes components that have been rigorously tested to meet GCC certification standards for both durability and performance in hot climates.

Updated Component List

Here are some of the notable improvements:

• Reinforced piston rings that offer longer service life under high stress.

• Forged connecting rods designed to endure higher power outputs.

• A dual-injection fuel system for balanced and efficient fuel delivery.

• Backed by a 100,000 km powertrain warranty, providing peace of mind for daily driving and weekend adventures.

Keep an eye on these aspects during your routine inspections:

• Watch out for any turbo lag, particularly below 2,000 RPM, as it may indicate performance issues.

• Monitor oil consumption closely during extreme heat, which can vary slightly depending on conditions.

• Although intercooler condensation was a challenge in earlier models, the 2025 release has addressed this with improved design measures.

Track Day Preparation Checklist

If you’re gearing up for a track day experience, preparation can make all the difference. Use this checklist to ensure every element of your engine and vehicle is ready to perform at its best:

1. Switch to a high-quality 5W-40 synthetic oil for better thermal stability and reduced friction.

2. Opt for high-temperature brake fluid to cope with the increased demands of track driving.

3. Check your tire pressures and aim for 36 PSI when cold for optimal contact and control.

4. Activate the "Sport" driving mode to enhance your driving experience by adjusting transmission and engine responses.

5. Temporarily disable traction control (by holding the designated button for 5 seconds) to fully engage your vehicle’s capabilities on the track.
