Castrol has published an independent study conducted with neuroscience firm Brainbox, revealing that the true thrill of driving stems from cognitive focus and controlled immersion rather than raw speed. Researchers tracked physical and neurological data across five distinct driving experiences at a UK track facility.
There is a well-known cinematic moment, immortalized in film, when a driver approaches seven thousand RPM and everything else fades away. Quantifying that visceral feeling is difficult work, but turning human emotion into raw data was the explicit goal of a recent project commissioned by Castrol. The initiative sought to answer a fundamental question about what makes driving genuinely thrilling, moving past the assumption that the answer lies entirely in four-figure horsepower or blistering acceleration times.
Inside the Track Tests: Monitoring Brain, Heart, and Gaze
To capture the physiological reality behind the wheel, the project enlisted Brainbox, a UK-based neuroscience technology and research company. Participants wore specialized equipment designed to monitor brain electrical activity, heart rate variability, galvanic skin response, and eye movement during five distinct driving tests.
All evaluations took place at a dedicated track facility in the UK operated by PalmerSport, a venue founded by former English Formula 1 driver Jonathon Palmer—who competed for Tyrrell, Williams, RAM Racing, and Zakspeed between 1981 and 1989. The testing roster exposed participants to a diverse fleet of vehicles. Drivers climbed behind the wheel of a McLaren Artura GT4, navigated a tight circuit in a SODI GT5 Kart, and tested a classic Land Rover Defender on an off-road course. Researchers also placed participants in the passenger seat of an open-top Le Mans-style JP-LM race car driven by a professional instructor.
The Three Pillars of Controlled Immersion
Analysis of the collected data indicated that driving thrill is not governed by speed alone. Instead, it arises from the convergence of three distinct neurophysiological factors operating at an elevated state. According to findings published by Castrol, those pillars consist of visceral factors involving intense mental and physical stimulation, intellectual engagement with the task, and emotional equilibrium balancing excitement against fear.
When those elements align within manageable limits for an individual, drivers enter a focused, flow-like state. However, if external stimuli exceed what a driver can comfortably process, the experience tips from productive engagement into fear, marked by erratic heart rates and disjointed eye movements.
That cognitive immersion showed up clearly in neurological telemetry. Drivers piloting the McLaren Artura exhibited the highest levels of brain and body arousal. Their blink rates plummeted to an average of just 2.5 per minute—compared to a normal resting rate of 15 to 20 blinks—while theta and alpha waves surged in the frontal lobe, indicating deep concentration and alertness.
Why Speed Takes a Backseat to Focus
One of the most striking insights from the project is that outright velocity is merely a contributory element rather than the primary driver of excitement. While the McLaren Artura boasts a top speed of 205 miles per hour, participants recorded similar thrill readings during the go-karting session on a technical circuit, where speeds hovered around 48 miles per hour.
Conversely, riding as a passenger alongside a professional instructor in the JP-LM race car triggered a spike in fast-flowing beta waves and a drop in theta and alpha activity. Researchers identified those neurological patterns as indicators of cognitive overload and fear rather than engaged control. When participants were at the controls themselves, operating within their perceived limits, they experienced excitement rather than intimidation.
“Thrill isn’t about speed, it’s about focus. The data shows real thrill as the moment a driver locks in completely, and it can be seen across the brain, heart and eyes.”

The conclusions offer a different perspective for everyday motorists. Because the neurological sweet spot depends on focus and control rather than elite velocity, drivers do not require a supercar to experience a genuine sense of connection behind the wheel.
Castrol noted that the research supports its performance-focused product development ethos, leveraging decades of technical insights gathered alongside motorsport teams and vehicle manufacturers. Company representatives emphasized that all evaluation activities took place on closed tracks under professional supervision, and the findings should not be interpreted as an endorsement of high-speed driving on public roadways.
