Lotus Avia X: Nurburgring Lap Record Attempt
- The circuit is around 13 miles in length with approximately 170 turns, making it one of the most challenging tracks globally.
- Lotus attempts a lap record at the Nurburgring with the Avia X, a purpose-built prototype with over 2,000 horsepower and 4,500 kg of downforce.
- To ensure accuracy and validation, a legal notary is hired to oversee the timing process during the lap record attempt.
- The Avia X is a modified version of a road car, utilizing road car technology with added components like competition tires and carbon brakes.
- The car features a 2.2 megawatt battery delivering 1500 kW to four motors, pushing the boundaries of what an EV road car can achieve.
- The lap record attempt at the Nurburgring involves managing thermal temperatures of the battery over the course of the lap to maintain maximum performance.
- Driving a lap at the Nurburgring is equivalent to 5,000 km on a normal road due to the stress and strain on the car and driver.
- The Avia X has over 4,000 kg of downforce, with a speed limit of 350 km/h to manage tire and downforce levels around the track.
- The car's chassis is a single-piece structure without separate front and rear subframes, providing high torsional and bending stiffness.
- The car features a DRS system for high-speed performance, with the rear wing element rotating to reduce drag and increase top speed.

Testing, Nürburgring challenges, battery cooling for performance.
- The car was extensively tested and validated using a full CFD model and road car wind tunnels, with instrumentation including load cells and gauges to monitor forces and correlate data back to maps.
- The Nürburgring, known as the "Green Hell," presents varying conditions and grip levels on each lap due to changing weather and terrain, demanding constant alertness from drivers even on straight sections like the Döttinger Höhe.
- Preconditioning the EV car's battery pack with external AC chillers and dry ice to cool it below ambient temperature before a fast lap helps prevent thermal issues and ensures consistent performance throughout the lap, with modifications like double-stacked radiators and increased airflow to manage the higher duty cycle compared to a road car.
