We all recognize the drill, correct? Open the door. Sit in. Buckle up. Clutch in, shift into neutral and start the engine. Next, find that traction control button and switch it off. It’s the auto fanatic’s version of a pre-flight check. However, you might want to skip that last step, particularly if you own a newer vehicle. Why? Well, chances are, you’ll actually improve your speed if you keep it on, and I’m not just talking about your daily drive—I mean always.
Don’t trust my word? Fair enough. How about insights from The Drive‘s dedicated racing driver and high-performance instructor, Nik Romano? His credentials exceed mine, I’ll concede. And he’s chosen the perfect vehicle to illustrate this for us today: a 2026 C8 Chevrolet Corvette.
This mid-engine sport coupe possesses much more than the essential components to zip around the racetrack. It also boasts an exceptional software suite. Nowadays, every automaker aiming for track capability features some form of race-based traction control system.
In contrast to traditional traction control systems, which merely reduce throttle based on ABS inputs, these modern suites perform electronic wonders with even the most clumsy driver inputs. Even basic traction control systems have shown to assist rather than hinder in practical situations; that’s why many racing series prohibited the tech in the ‘80s and ‘90s. Current systems are infinitely more sophisticated than those archaic on/off toggles.
Whether you’re in a Cadillac or Chevy, GM has a unified name for its advanced traction control system: Performance Traction Management, or just “PTM.” But how effective can it genuinely be? Well, during the early 2000s, GM worried that buyers might struggle to handle 400 horsepower on urban roads; today, GM markets several rear-wheel-drive performance models boasting even greater horsepower, and PTM deserves part of the credit for giving the company the courage to engage the potential risk. All I can say is, more Blackwings, please.
To showcase just how effective these systems have become, Romano took the Corvette to Buttonwillow Raceway in California for some intense laps. Beginning with the system in “Touring” mode (the preset for most everyday driving), Romano set a lap time for each of the PTM’s performance settings, progressing from Dry, Sport, and the various Race levels. And then the coveted mode: Pro, which is Chevy’s way of saying “you’re on your own.”
PTM works in harmony with the car’s other systems, including the Magnetic Ride Control suspension and (when applicable, as in the Corvette), the automatic transmission. It also relies heavily on the vehicle’s electronic stability control system. The sensors that measure a vehicle’s pitch (front/rear movement) and yaw (side-to-side movement) are essential for forecasting vehicle dynamics.
This not only enables them to excel at their primary functions (anticipating and intervening before drivers completely lose control), but also makes them superb instruments for monitoring and proactively addressing varying conditions on a racetrack, where weight distribution is critical.
Romano spent the day testing the C8 in different modes across various tire and surface temperatures to negate any inconsistencies in lap times. The outcomes? Well, if you’ve been paying attention, they should have been unsurprising. While the Touring lap was significantly the slowest, it wasn’t the Pro laps that clocked the fastest times. That distinction went to Race 2.
After examining the data, the results speak volumes. Not only were Romano’s quicker times faster with PTM engaged, but he was also more fluid in his driving. So, the next time you embark on your commute (or perhaps even on the track), reconsider turning off traction control.

**Advancing Lap Times: The Advantages of Keeping Traction Control Engaged**
In the realm of motorsport, every millisecond is crucial, and racers are perpetually searching for ways to enhance their lap times. One frequently debated aspect in racing is traction control (TC). While some purists advocate for an unfiltered driving experience, many racers and teams acknowledge the benefits of maintaining traction control engaged. This piece delves into the advantages of traction control in improving lap times and overall track performance.
### Comprehending Traction Control
Traction control is a system engineered to prevent wheel spin during acceleration by modulating engine output or braking individual wheels. This technology provides better track adhesion, particularly in conditions where grip is compromised, such as on wet or slick surfaces.
### Advantages of Keeping Traction Control Engaged
1. **Improved Grip and Stability**: One of the main benefits of traction control is its capability to uphold ideal grip levels. By avoiding excessive wheel spin, drivers can accelerate more efficiently out of corners, resulting in enhanced exit speeds. This stability is vital for maintaining control, especially in high-speed scenarios.
2. **Reliable Performance**: Traction control systems offer a degree of consistency that can be hard to achieve manually. Drivers can concentrate on their racing lines and brake points without the anxiety of losing control due to sudden traction loss. This reliability leads to more dependable lap times, as drivers can replicate their performance lap after lap.
3. **Increased Cornering Speed**: With traction control engaged, drivers can bring their vehicles closer to the limits of grip without fearing loss of control. This capability enables higher speeds through corners, significantly reducing lap times. Maintaining speed through turns is critical for competitive racing.
4. **Flexibility to Track Conditions**: Racing conditions can swiftly shift due to weather changes or track surface deterioration. Traction control systems can adjust to these alterations, equipping drivers with the support needed to maneuver varying situations. This adaptability can be transformative during races with fluctuating conditions.
5. **Less Driver Fatigue**: Managing traction manually can be both physically and mentally taxing, especially during long races. Traction control lessens some of this strain, allowing drivers to conserve energy and concentrate on strategy and race tactics rather than constantly correcting for traction loss.
6. **Boosted Confidence**: Knowing that traction control is active can enhance a driver’s confidence, enabling them to push harder without the fear of losing control. This psychological advantage can result in improved performance and faster lap times.
7. **Better Tire Management**: Excessive wheel spin can accelerate tire degradation, which is detrimental during extended races. By regulating wheel slip, traction control aids in prolonging tire life, allowing drivers to maintain competitive lap times throughout the race.
### Conclusion
While the discussion over the use of traction control in motorsport persists, the benefits of keeping it engaged are evident. Enhanced grip, reliable performance, increased cornering speeds, adaptability to shifting conditions, reduced driver fatigue, boosted confidence, and improved tire management all contribute to faster lap times. For drivers aiming to optimize their performance on the track, utilizing traction control may be one of the most effective strategies to realize their racing objectives.
