Case Study | Lamborghini Urus

At PERON Automotive, we love the EA825 4.0 TFSI engine, and the Lamborghini Urus showcases this engine in the best possible way with supercar performance and style. Our project elevated this SUV from Stock to Stage 1, integrating high-performance components such as the Akrapovič exhaust and ITG air filter to achieve 745 hp. With advanced ECU and TCU recalibrations, we optimised the vehicle's performance across all aspects, transforming the Urus into an even bigger powerhouse that combines sporty sophistication with exhilarating drivability. The improved driving characteristics enhance both usability and the fun factor, making the performance gains seem almost absurd in an SUV.

The Brief

The development brief for the Urus was to build on our success with the RS 6 (C8) by implementing subtle upgrades for this super SUV. Our class-leading ECU and TCU calibrations transform this beast into a much faster, smoother car suitable for daily commutes or terrorizing supercars.

For enhanced auditory pleasure and additional power, we replicated some of the steps taken with the RS 6, adding an Akrapovič exhaust system and an ITG panel filter. The new software and hardware package allows the Urus to remain tamed in Comfort mode while being a bit louder and more aggressive in Sport mode, all at the push of a button and whilst retaining the factory downpipes and emissions compliance.

Our Results

This particular Urus has progressed from Stock to Stage 1, resulting in excellent performance and superior sound characteristics with minimal hardware upgrades. Initial stock dyno runs gave lower than expected numbers and our data logging showed the car was suffering with a bad tank of fuel plus high ambient temperatures. The Stage 1 dyno runs were performed with a fresh tank of 99RON fuel and better conditions. With minimal hardware changes and a safe, sensible calibration, we are pleased with the results.

The Urus translates the solid dyno numbers into an exciting driving experience with strong power delivery and hard-hitting response. The enhanced driving characteristics improve both usability and enjoyment, making the performance gains feel almost unbelievable in an SUV.

  • ~60-80 hp increase in maximum power under normal conditions
  • ~140-170 lb-ft increase in maximum torque

Establish Baseline and Identify Areas for Improvement

Our first step towards any transformation is to test the vehicle both on our in-house DynoJet 424x linked dyno cell and on the road. This evaluation serves to establish a baseline of the car’s performance capabilities and gives us a feel for what it wants to improve the driving experience. By assessing the vehicle under controlled conditions and real-world scenarios, we identified a few areas for improvement. We discovered the Urus drives similarly to the very familiar Audi RS 6 (C8) and required a similar upgrade path.

The air intake system was better than the RS 6 but still left much room for improvement. The exhaust system was restrictive and, although louder than the RS 6/RS Q8, still muted the engine’s potential sound. The factory gearbox calibration had conservative limits and shift strategies that inhibited the engine's capabilities without being smooth. The factory engine calibration left a lot of potential untapped, despite already being more powerful than the RS 6/RS Q8. Addressing these areas would transform the Urus into a true super SUV, rivaling exotic car performance while maintaining the sporty luxury expected of a Lamborghini.

Performance Parts

We strategically selected performance upgrades to safely increase power and improve the vehicle's acoustic profile. The upgrades began with an ITG Panel Filter in the factory airbox, which reduces pressure drop in the turbo inlets to improve air delivery and engine responsiveness. To ensure ignition efficiency, a new set of NGK spark plugs with an optimised gap was installed, providing consistent ignition performance at increased power levels.

The exhaust system received enhancements with an Akrapovič Slip-On Line exhaust system. This system provides an aggressive but tailored sound, improved exhaust flow, and reduced weight. The Akrapovič system for the Urus is a factory option we highly recommend. These performance hardware upgrades work in synergy with the ECU and TCU calibrations to create a complete package that is greater than the sum of its parts.

Engine Control Unit Calibration (ECU)

To unlock the full potential of the Lamborghini Urus with its upgraded components, we optimised the engine ECU calibration. Fuel delivery adjustments ensured optimal rates for the increased air intake and exhaust flow, facilitating efficient combustion at higher power levels. Ignition timing was precisely fine-tuned to match the enhanced airflow and fuel mixture, maximising power output and preventing knock or pre-detonation while maintaining factory safety margins, which is critical when running on 99RON fuel.

Turbocharger control system modifications allowed for higher boost levels, significantly increasing power without exceeding safe operating limits for the turbocharger or engine. Torque output curves were recalibrated to provide smoother power delivery across a broader RPM range, enhancing both performance and drivability. An optimised cooling strategy was used to maintain ideal engine temperatures, ensuring consistent performance under various driving conditions. Additionally, engine RPM and vehicle speed limits were adjusted to give a broader range of performance for both daily and spirited driving scenarios.

Transmission Control Unit Calibration (TCU)

The transmission control unit (TCU) calibration was refined to complement the upgraded engine performance of the Lamborghini Urus. We recalibrated shift points to ensure they align perfectly with the enhanced torque and power curves, resulting in smoother and faster gear changes. By increasing the torque limits and optimising the hydraulic pressure, we improved the gearbox's ability to handle the increased power output without compromising reliability.

Furthermore, adjustments were made to the shift strategies in various driving modes. In Comfort mode, shifts are seamless and refined, enhancing the daily driving experience. In Sport mode, the shifts become more aggressive, providing quick and precise gear changes that contribute to the vehicle's exhilarating performance. These TCU calibrations ensure that the Urus offers a versatile driving experience, seamlessly transitioning from a luxurious SUV to a performance powerhouse at the push of a button.

Future Upgrades

This Urus is currently at the Stage 1 level, equipped with an ITG Panel Filter in the airbox and an Akrapovič exhaust system. The next step is to add Nortech Performance downpipes and link pipes, then upgraded intercoolers for better performance consistency under extreme conditions. For improved intake flow and aesthetics, an Eventuri carbon intake is planned to round out the upgrades from Stage 1 to 2+.

The Stage 3 upgrade includes TTE1020 turbos and 4 bar MAP sensors, a package proven through our collaboration with QST on the record-setting RS 6 (C8), and easily adaptable to this chassis.
