In motorsport, three seconds is an eternity. It’s the difference between pole position and starting mid-pack, between standing on the podium and watching it from pit lane. Teams will spend hundreds of thousands of dollars chasing tenths of a second in optimizing aerodynamics, engines, or tires. Yet in a recent study conducted with professional race car drivers on a racing simulator, lap times dropped by three seconds, without changing the car at all.
The difference came from the driver’s brain.
The findings, published in Frontiers in Sport and Active Living and in collaboration with PitFit Training,builds on a growing realization inside the paddock that in racing the speed of the car can be limited by the driver as much as the machinery. One critical component is that when driver cognitive performance improves, race car speed follows.
From the outside, race car driving looks like reflexes and bravery. From the inside, it is an unbroken chain of decisions made under extreme pressure. A single lap requires hundreds of micro-judgments: brake now or three meters later, turn in earlier or wait, unwind the wheel or correct the slide, commit to full throttle or hesitate for a fraction of a second.
None of those decisions are dramatic on their own. But repeated across 10, 14, or 18 corners, small delays compound quickly. Improve execution by only 0.15–0.20 seconds per corner, and you suddenly can unlock multiple seconds over the course of a race.
This is why elite driving requires sharp cognitive function. The faster the brain processes information—and the more consistently it does so under fatigue—the faster and smoother the car can be driven.
To explore whether cognitive enhancement could translate into measurable performance gains, we studied 58 licensed professional race car drivers using a high-fidelity racing simulator. Drivers completed a four-phase protocol: baseline testing, an acute dose (200mg) of Cereboost™, two weeks of daily supplementation (200mg per day), and a final test combining chronic use with an acute dose (2 weeks of 200mg/day and an additional 200mg prior to testing).
Cereboost™ is a concentrated extract of American ginseng, studied previously for its effects on attention, mental fatigue, and executive function. Importantly for motorsport, it is caffeine-free and not banned by any racing sanctioning body.
Drivers completed cognitive assessments and then drove a Ferrari 488 GT3 Evo around Road America for thirty minutes under controlled conditions. What mattered most was not mood or short cognitive tests, but what happened on the track.
After 2 weeks of daily supplementation, drivers recorded a three-second reduction in lap time, a result that a result statistically significant. In racing standard, an improvement of just 3 second is practically enormous. Telemetry analysis revealed that drivers reached full throttle sooner in the corners, suggesting possible adjustments in driving patterns that could reflect cognitive or perceptual factors.
At first glance, the result seems almost too good to be true. How could a nutritional intervention shave seconds off a lap when physical fitness, reaction time, and technical skill are already elite?
But the explanation lies in how performance occurred.
Cereboost™ did not turn drivers into daredevils. It did not make them brake later or take bigger risks. Instead, the data showed a decrease in small inefficiencies that generally appear under prolonged cognitive load. The observed improvement in processing time seems associated with drivers’ ability to recognize grip changes earlier, correct slides sooner, and commit to throttle with less hesitation.
These changes are subtle. You would not see them as dramatic steering inputs. You see them as smoother traces in telemetry and faster lap times.
Racing places extraordinary demands on the brain. Drivers must simultaneously manage speed, traffic, tire behavior, radio communication, and strategic awareness often while dehydrated (2- 3% of body mass lost as sweat), overheated (core temperatures of 38.5-39.5℃), and physically exhausted (burn 600-700 calories per hour of racing).
When mental fatigue sets in, precision erodes, braking becomes inconsistent, throttle application slows, and micro-errors accumulate. Even a few milliseconds of delay when catching oversteer or applying power can translate into lost speed down the next straight.
Supporting cognitive endurance, rather than chasing momentary stimulation through caffeine usage, is what preserves performance deep into a run. This may help explain why drivers reported strong subjective improvements in mental clarity and confidence alongside their objective performance gains. In elite sport, perception matters. Feeling sharp reinforces decisiveness—and decisiveness is speed.
The implications extend beyond motorsport. The same brain mechanisms are at play in traditional “stick and ball sports” as well as esports where athletes make rapid decisions under fatigue or juggling high-stakes tasks under sustained cognitive load.
While the arena may change, the brain’s demands remain the same.
Perhaps the most important lesson from the study is performance isn’t always constrained by strength, aggression, or effort. Sometimes the limiting factor is how efficiently the brain can process information and turn perception into action.
When that bottleneck is eased, the body and the machine can finally express their full potential.
For decades, motorsport performance focused almost exclusively on the car. Even when sport science entered the paddock, attention centered on heat stress, hydration, sleep, and physical conditioning. The brain remained understudied and to this day it still is minimally researched.
This study is among the first to demonstrate, with real driving outcomes, that supporting cognitive performance can produce race-relevant gains. Three seconds is not a marginal improvement—it’s transformational.
Future work will need to confirm whether these findings translate to on-track racing and whether older drivers or longer driving stints magnify the effect. But the direction is clear in modern racing, horsepower still matters. Aerodynamics still matters. But at the sharp end of the grid, clarity is speed.
And sometimes, the fastest upgrade isn’t found in the garage—but in the driver’s head.
