Polo WRC – an unassuming monster
In the automotive world, we often encounter cars that flaunt their power ostentatiously – wide fenders, huge spoilers, aggressive bumpers. However, sometimes true beasts come in unassuming packages. Such is the hero of this article – the Volkswagen Polo 6R R WRC Street, which has been modified to a level beyond all imagination.
The car was presented by French YouTuber “Ju Motorsport,” who had the opportunity to test this incredible machine. According to the owner, who wished to remain anonymous, this is an extremely powerful Polo WRC with power exceeding 700 HP. The French workshop MTR Motorsport worked on the project.
Specification and engine modifications
What impresses most in this project are the technical details and advanced engine modifications:
- Engine: 2.0 TSI CDL, forged internals
- Turbocharger: Garrett GTX 30.76
- Power: Over 700 HP and approx. 700 Nm of torque
- Weight: Around 1200 kg
- Power-to-weight ratio: Similar to a Bugatti Chiron
- Injection: Dual injection system with additional methanol injection
- Throttle body: 70 mm internal, 76 mm external
- Exhaust system: Full 76 mm system by MTR with two mufflers for relative discretion
- Intake manifold: Aluminum Integrated Engineering (replacing the factory plastic one)
- Engine management: KMS FA23 ECU (Kronenburg Management Systems)
- Boost Controller: PLEX PBC PRO with OBD CAN BUS function
- AFR Gauge: AEM AIR/FUEL RATIO gauge
- Methanol injection: Snow Performance system with solenoid
- Wheels: 17-inch OZ Racing Alleggerita HLT wheels (7 kg each) with Toyo 225/45 R17 tires Suspension: KW Clubsport with Powerflex bushings
- Brakes: Unfortunately, original brakes were retained, which even sparked controversy among commenters
In the engine bay, numerous aftermarket elements immediately catch the eye. The intake manifold has been replaced with an aluminum product from Integrated Engineering, which – unlike the plastic original – offers increased capacity and better airflow. Another visible element is the aluminum intake pipe leading to the turbocharger, ending with a large Pipercross filter.
The valve cover has also been replaced with an aftermarket aluminum version, which not only improves aesthetics but also heat dissipation. The car has been equipped with a dual fuel injection system with additional methanol injection, which allows for significant power increases while cooling the charge air.
The car has evolved since its purchase in December 2013. The owner started with Stage 2 with the original turbocharger, then moved to an ATP 30.71 turbo with approximately 535 HP, until finally deciding on a complete modification with forged engine internals and the current configuration.
Interior and electronics
The car has retained much of its interior in factory condition, which is quite unusual with such powerful modifications. As the owner admits, he wanted to maintain a certain level of comfort for daily use – hence the original seats were kept as well as the rear bench, which can be removed if necessary “when going to war,” as the owner jokingly put it.
However, there were several significant modifications. Behind the steering wheel is an AEM AIR/FUEL RATIO gauge, showing the air-to-fuel ratio (the video shows a reading of 16.20, with a scale from 8 to 20). Under the Climatronic climate control panel is an additional switch, probably controlling one of the numerous modifications.
Particularly noteworthy is the PLEX PBC PRO boost controller mounted behind the steering wheel – an advanced device allowing precise control of boost pressure, with the ability to connect to the OBD system and offering a range of engine protection functions.
On the left side of the engine bay, you can see the blue KMS FA23 ECU control unit – a specialized computer from the Dutch company Kronenburg Management Systems, designed with heavily modified engines in mind. Behind the right headlight, a Snow Performance water-methanol mixture injection system solenoid has been installed, which helps control engine temperature and prevents detonation at high boost pressure.
Controversies – full power, original brakes
One of the most controversial aspects of this project is the fact that the owner decided to keep the original brakes, despite the significant power increase. In the comments under the video, many viewers expressed concern about this, considering it a potentially dangerous solution.
However, the owner argues that with a weight of just 1200 kg, the original brakes are still sufficient for his driving style, which does not include track use. As he says himself: “Freinage d’origine il est mordant” – the original brakes are effective enough.
Performance – a true beast
During the test, the car showed impressive performance. Although exact acceleration times were not given, the passenger’s reaction clearly indicates the brutal power of this car. During filming, the car reaches speeds exceeding 280 km/h, and thanks to the heavily modified chassis and suspension, power is transferred to the road in a surprisingly effective way.
Interestingly, despite such extravagant performance, the car maintained a relatively discreet external appearance. Apart from the sporty wheels and subtle black accents on the bumpers, nothing indicates the potential lurking under the hood.

Summary
This Volkswagen Polo WRC project perfectly illustrates how far one can go in modifying a production car. With power exceeding 700 HP in a compact body weighing just 1200 kg, the car offers a power-to-weight ratio on par with supercars costing millions of euros.
Although some decisions, such as retaining the original brakes, may be controversial, one cannot deny the impressive technical craftsmanship and courage in pushing the boundaries of what’s possible with this small hot-hatch shown by the owner and the workshop involved in the project.
