EA825 OPF

EA825 OPF

Introduction

In 2012, VAG introduced the 4.0 TFSI engine to replace the 5.0 V10 biturbo, marking a significant advance in terms of sobriety and performance. The major innovation of this engine was the positioning of the turbochargers inside the V8, between each row of cylinders. This arrangement significantly reduced the response time (lag) and quickly ensured a high temperature of the catalysts, thus improving the engine’s overall efficiency.

New engine version

In 2017, a new version of the 4.0 TFSI engine, christened EA825, was developed in collaboration with Porsche. This evolution, based on the EA839 V6, was first integrated into the Porsche Panamera. Unlike its predecessor, the EA824, the EA825 is uniform whatever its power. This uniformity has aroused the enthusiasm of our development team, as it has enabled an exceptional increase in performance, even in the basic version of this engine.

Engineer's notes

The 4.0 TFSI engine is the pinnacle of performance at VAG.

Featured in the group’s high-end vehicles, it offers first-class performance. While the EA824 was developed under the leadership of Audi, the EA825 came from the labs at Porsche, and this distinction is clearly felt.

Indeed, the 4.0 TFSI stands out as an exceptional engine, where most of the problems related to injection and cooling have been solved.

Picture of Audi RS6 inside
This new engine offers no less than nine power levels, ranging from 460 to 666 horsepower, and after reprogramming, all versions can exceed the 700 horsepower mark, provided that certain parameters allow it, such as the intake system or the turbos, to name a few.

A carefully tailored sound.

What is most impressive is the difference in sound carefully adapted by VAG depending on the type of vehicle. For example, the RSQ8 and Urus share many elements, including the engine, but their exhaust systems are totally different. This makes the RSQ8 relatively silent compared to the Urus.

WOT engineers have passionately invested in the development and testing of this exceptional engine, through our RS6 and SQ7 development models.

The result after optimization is simply staggering.

We get no less than 1000 Nm of torque from the lowest engine speeds, literally catapulting the driver to the bottom of their seat, for an unparalleled and indescribable driving experience.

The development process

We select the vehicle which combines the most significant criteria contributing to pollution, in particular: consumption, weight, air resistance (drag coefficient) and type of transmission. For this EA825 OPF engine, we opted for the Audi RS6 4.0 TFSI (Perf.) model. If the vehicle successfully passes the numerous pollution tests, the official verification body can logically conclude that the other, less polluting models in the range will also obtain positive results. This is why, within WOT, such importance is given to the engine code.

What about the warranty?

At WOT, we invest heavily in research and development to provide you with an experience where performance and reliability go hand in hand. However, it is possible that during a routine inspection, the manufacturer has detected that your vehicle has undergone modifications. Even if the improvements made by WOT are homologated, this detection can lead to the loss of the factory warranty.

For this reason we have created an additional motor warranty, specifically designed to meet your highest demands.
