New conversion kit gives legacy gas tow tractors new, sustainable life with lithium-ion power

Tiger Repower

Anaheim, Calif., Sept. 12, 2023 – With an industry goal of net-zero emissions by 2050, airports worldwide are working toward a sustainable future – and electrifying ground support equipment (GSE) can make an immediate impact. Today, Tiger is reducing the financial burden of electrification with a first-of-its-kind conversion kit – making it fast, easy and cost-efficient to upcycle current tractors. Tiger Repower converts internal combustion engine (ICE) tow tractors to lithium-ion (Li-ion) power, offering ground support operations a modern, clean and green way to bring new life to existing fleets. The latest in electrification technology, Li-ion helps operations save thousands, cut carbon emissions and improve safety.

“Tiger Repower allows operators to achieve zero emissions in a single day. Maximizing existing tractor investments with an easy-to-install conversion kit is something that airports, governments and ground support operations alike can stand behind,” said Keith Simon, CEO, Waev Inc. “With Tiger Repower, we’re eliminating the reasons to not go electric by offering the benefits of Li-ion technology without a burdensome investment.”

One Step Closer to Net Zero
Compared to a single internal combustion tractor emitting an average of 3,250 kilograms of CO2 annually, an electric tow tractor emits zero CO2 – helping reduce an airport’s overall pollution output and contribute to the aviation industry’s sustainability goals. Tiger Repower removes barriers for electrification adoption by providing a Li-ion upgrade that costs up to 50 percent less than purchasing a new tractor. Ongoing savings are further realized through zero powertrain maintenance and no fuel costs.

Easy Install
A Tiger Repower conversion kit is easy to install and can be completed in the shop or on the tarmac. Once the ICE powertrain is removed, the total installation takes 8-12 hours with two people – electrifying the tow tractor with Li-ion power in just one day.

Smart Vehicle Technology
Tiger Repower enables smart vehicle technology not realized with gas vehicles. A new anti-rollover feature enhances safety by limiting the vehicle’s speed while turning. Brake interlock forces the operator to be at a complete stop and the brake fully depressed before shifting to forward or reverse. Onboard diagnostics help rapidly call attention to an issue so it can be addressed, further increasing productivity and safety for crews.

Flexible Charging
Li-ion-powered tow tractors minimize the need for infrastructure changes with an onboard charger compatible with traditional single-phase outlets and offboard charging compatibility with multiple DC fast chargers. Flexible charging means Tiger Repower tow tractors can adapt to a wide range of infrastructure readiness—without requiring heavy investment in new charging infrastructure. Tiger Repower can also be opportunity charged anytime for further flexibility.
