Meet The Team: Jérémie Lolieux - Physics Designer

Physics is an important part of any racing game, and it's why we want to be upfront about what experience Endurance Motorsport Series will be offering players upon release. To give you more details on that, here's Jérémie, the physics designer who worked on the physics of the game!

Introduction to the Endurance Motorsport Series community

My name is Jérémie Lolieux, and I work as a physics designer on Endurance Motorsport Series, focusing on vehicle handling, tire behaviour, and how the car interacts with the track and weather conditions. I come from both a game development and sim-racing background, so my goal is to bridge authentic endurance racing sensations with an experience that remains enjoyable and readable for a wide range of players.

What group of players are the physics aimed for in Endurance Motorsport Series?

The physics are aimed at players looking for a sim-lite experience: something clearly more realistic and demanding than an arcade racer, but not as punishing and demanding as a pure hardcore simulator. Wheel users who enjoy cockpit view and endurance strategy will find enough depth, while gamepad players with driving aids enabled can fully enjoy the driving experience of endurance racing.

What effects are simulated in Endurance Motorsport Series physics?

The physics simulate key elements of real endurance racing such as tire grip evolution, fuel load impact on handling, suspension behaviour, potential damages or mechanical issues, and aerodynamic downforce at different speeds. Weather changes and track conditions also affect how much grip is available and how stable the car feels over a stint.

How much does the physics vary when accounting for tire compounds, weather, and tire wear?

Different tire compounds offer distinct trade-offs between peak grip, durability, and warm-up time, so choosing the right compound for the stint and the weather is a real strategic decision. The soft compound is the most performant one, but it will lose efficiency quicker than medium and hard tyres. The tyre temperature is also important, based on weather conditions and driving style. A soft compound will overheat more easily than a hard one, especially if the track temperature is high.

As the tires wear and the weather evolves, players will feel progressive changes in braking distances, cornering stability, and traction, encouraging them to adapt driving style and pit strategy rather than dealing with sudden, unpredictable changes.

How do the physics vary between vehicle classes, and the vehicles inside each class?

Each class — Hypercar, LMP2, and GT — is built with different levels of power, weight, downforce, and mechanical grip, so they naturally require different braking points, lines, and race craft to drive effectively. Within a class, vehicles are differentiated by characteristics such as engine layout and power delivery, aero efficiency, and suspension setup ranges, using reference data and category rules so that they feel distinct but remain balanced for multi-class racing.

Can players expect a greater simulation feel by turning off all assists such as ABS, TCS, etc?

Yes, turning off assists like ABS and traction control gives a more raw and demanding driving experience, with more direct feedback from the tires and a greater risk-reward dynamic on braking and corner exit. However, assists are tuned to preserve the underlying physics rather than replace them, so players can progressively reduce aids as they gain confidence without losing the core handling model.

What is the gameplay experience that Endurance Motorsport Series is trying to achieve?

The game aims to recreate the feeling of being part of a real endurance team, where driving is only one piece of a larger strategic puzzle involving multi-class traffic, weather management, and pit decisions. By letting players jump between driving and the engineer role, the experience mixes on-track intensity with tactical, team-oriented decision making over long races.

What was important to the team at KT when developing the physics for Endurance Motorsport Series?

The team's priority was to leverage the KT Engine to deliver believable vehicle behaviour on different tracks and surfaces, while always keeping the experience readable and fun over long stints. Finding the right balance between technical simulation (tires, aero, drivetrain, weather) and accessibility for players with different skill levels and controllers was a core design constraint from the start.

What are some tools in the KT Engine that bring the physics to life in Endurance Motorsport Series?

KT Engine provides an in-house physics framework that integrates vehicle dynamics, tire models, and surface properties, making it possible to tune each car class precisely for different conditions. On top of that, internal debug tools such as telemetry views, and live parameter tweaking help iterate quickly on handling, making sure what designers feel on track matches the intended behaviour.

What was your favourite part about developing the physics for Endurance Motorsport Series?

The most satisfying part was shaping the flow of an endurance stint: feeling the car evolve as the fuel burns off, tires wear, and weather changes, and then seeing how players respond with their own strategies and driving styles. Bringing together multi-class traffic, long-run tire management, and the engineer role into a cohesive, race-long experience is where the physics really came alive for the project.
