This month, we’re turning our attention to the Hyundai i20 N. A vehicle that perfectly combines rally-inspired engineering with everyday practicality, sharp handling, and serious hot hatch performance. Developed by Hyundai’s high-performance N division, the i20 N delivers engaging driving dynamics, aggressive styling, and an exhilarating driving experience. Pair that with the addition of a TDI-Tuning plug-and-play system, and the i20 N becomes an even more responsive and exciting performance hatchback.
Tuning Potential
The Hyundai i20 N is powered by a turbocharged petrol engine engineered to deliver impressive performance, rapid throttle response, and an engaging driving experience. Whether attacking your favourite B-road, enjoying a spirited weekend drive, or tackling the daily commute, the i20 N is designed to provide excitement, confidence, and enjoyment behind the wheel.
However, like most modern vehicles, the i20 N’s engine is governed by factory software calibrated to satisfy global emissions regulations, fuel economy targets, and long-term reliability standards. As a result, there is considerable untapped performance potential built into the vehicle from the factory.
Our CRTD4 tuning system unlocks that hidden potential, delivering noticeable increases in both power and torque. The result is stronger acceleration, improved mid-range performance, and enhanced responsiveness throughout the rev range. The i20 N also benefits from improved efficiency during steady driving conditions, helping reduce fuel consumption without compromising reliability, manufacturer warranties, or safety.
What We Offer
TDI Tuning specialises in traceless, plug-and-play tuning systems that enhance performance without permanently modifying the vehicle’s ECU. Unlike traditional remapping, which overwrites factory software and leaves a digital footprint, our system can be installed in under an hour, removed at any time, and leaves no trace behind.
This is especially valuable for Hyundai i20 N owners who may have their vehicle on finance or lease agreements. Our system allows you to enjoy enhanced performance while maintaining peace of mind regarding warranty protection and future resale value.
The tuning box integrates seamlessly with the i20 N’s engine management system, working in real time to optimise fuel delivery and turbocharger performance. For additional flexibility, our optional Bluetooth app control allows you to adjust performance settings instantly from your smartphone.
With our system installed, the Hyundai i20 N sees impressive gains over stock, with significantly increased horsepower and torque. The result is sharper throttle response, stronger in-gear acceleration, and even more engaging performance, delivering a more exciting and rewarding driving experience. This already impressive hot hatch increases from 201 BHP & 275 NM to an impressive 247 BHP & 338 NM, transforming the i20 N into a vehicle that feels noticeably quicker, more responsive, and even more enjoyable on every drive.
Performance Gains
The impact of a TDI Tuning system on the Hyundai i20 N is immediate and highly noticeable. Owners can expect:
- Increased horsepower for stronger acceleration and more effortless overtaking performance, over 40+ BHP
- Enhanced torque delivery for improved flexibility and mid-range performance, boosting torque by over 60+ NM
- Improved throttle response for sharper and more immediate acceleration
- Potential fuel savings of up to 20% during steady motorway driving
These enhancements transform the i20 N’s driving characteristics, making it feel more responsive, more engaging, and even more rewarding to drive. The additional torque provides greater flexibility through the gears and improved acceleration out of corners, while smoother power delivery enhances both everyday drivability and spirited driving enjoyment.
Additional Benefits
Our traceless installation process ensures complete peace of mind. The system can be removed quickly at any time, returning the vehicle to its factory condition with no evidence of modification.
The optional Bluetooth control app adds further versatility, allowing you to tailor performance to suit your driving style and requirements. Whether you’re prioritising efficiency for daily driving or maximum performance for spirited road use, switching modes is quick and effortless.
Conclusion
The Hyundai i20 N is already one of the most exciting and capable hot hatchbacks on the market. Still, when paired with a TDI Tuning system, it becomes an even sharper, more exhilarating performer. Combining agile handling with enhanced power, improved response, and greater efficiency, it delivers meaningful improvements exactly where enthusiastic drivers want them most.
By unlocking hidden performance, increasing torque, and optimising efficiency, our system enhances every aspect of the driving experience. The result is an i20 N that feels quicker, sharper, and ready to make every journey more enjoyable.
