NASCAR tech made for Blackhawk pilots and Hendrick – Sports News
When legendary Hendrick Motorsports crew chief Chad Knaus, who was just lately noticed with Carson Hovecar, reached out to Rini Technologies in 2015, he was making an attempt to unravel a drawback he’d seen in stock vehicles: drivers battling heat exhaustion in scorching 140°F cockpits. The resolution? A compact, electrically powered cooling system initially developed for army Blackhawk helicopter pilots.
Rini Technologies had spent the early 2000s creating cooling options for army personnel in chemical, organic, radiological, and nuclear (CBRN) fits. Their Personal Cooling System (PCS) was a light-weight, battery-powered vest that circulated cooled fluid to help defend troopers in excessive environments. Recognizing its potential, they quickly re-engineered this into the PCS-Auto — a race-ready, miniaturized cooling unit wired immediately into a car’s 12V electrical system. It comes as Hovecar despatched a blunt message to Rick Hendrick after his heartbreak at Michigan International Speedway.
“The PCS-Auto is powered via 12 V and employs patented miniature refrigeration technology to continuously chill a flow of water to the Cooling Shirt,” Rini notes on their web site. Weighing roughly 1.8 kg, it delivered environment friendly, uninterrupted cooling — not like cumbersome, ice-based systems — with out compromising cockpit weight distribution. It didn’t take long earlier than NASCAR groups embraced the tech.
Cooler driver temperatures led to fewer heat-related points, improved consolation, and higher focus during grueling races underneath blistering circumstances.
It additionally unfold to IndyCar when the Aeroscreen roof system intensified cockpit heat — and Rini’s PCS-Auto grew to become the one cooling system accredited underneath the 2025 IndyCar rulebook.
Today, the ripple results of this technological breakthrough are being felt at Formula 1. In response to the intense temperatures drivers endured — most notably during the 2023 Qatar Grand Prix — the FIA fast-tracked a “heat hazard” regulation.
From 2025, groups could add a new cooling inlet and non-compulsory fluid-cooling systems within driver overalls; by 2026, such systems will grow to be obligatory in choose scorching circumstances.
While some F1 groups are prototyping their own options, the familiarity and confirmed efficiency of NASCAR-derived units just like the PCS-Auto offer a clear jumpstart. Motorsport.com reported that F1’s new system revolves round pumped cooled fluid circulating in driver overalls — a idea practically similar to NASCAR and IndyCar systems.
Still, challenges stay in translating NASCAR tech to the F1 cockpit. Drivers at Bahrain and Jeddah cited present systems as overly cumbersome and needing additional optimization, particularly with weight penalties and built-in seat design posing hurdles.

However, the speedy adoption of cooling tech down the motorsport ladder — army to NASCAR to IndyCar to Formula 1 — marks a uncommon case of upward technological diffusion.
Looking forward, F1 groups face intricate engineering challenges: integrating cooling items into the tight confines of next-gen cockpit interiors, managing further heat masses, and conforming to strict aerodynamic profiles. But the blueprint laid out by Blackhawk pilot tech, refined by NASCAR veterans like Chad Knaus, offers them with a highly effective head begin.
