The Most Powerful Silverado Ever. Available as Hybrid and Plug-In Hybrid Electric Pickups.

The all-new Chevy Silverado and GMC Sierra 2500 & 3500 HD pickups were built to handle a work truck’s toughest jobs – with the power, performance, and versatility needed on the job site. Now, XL Fleet’s market-leading hybrid and plug-in hybrid systems are ready to electrify the Silverado / Sierra 2500 and 3500 HD work trucks to give commercial and municipal fleets a proven way to meet sustainability goals without disrupting operations or performance.

Fleet-Ready™ Results

XL’s electrification upfits turn ordinary gas-powered vehicles into cleaner, more fuel-efficient versions that can help you meet sustainability goals while leaving the OEM powertrain (engine, transmission, fuel, and exhaust systems) completely intact. And because the XLH and XLP systems work in parallel with the OEM powertrain, the plug-in, and hybrid electric Silverado / Sierra both perform as you expect them to, without range concerns.   

Hybrid and Plug-in Hybrid Silverado/Sierra

The XLH and XLP system are available on select 4WD GM Silverado and Sierra 2500 / 3500 HD models with 6.5-ft and 8-ft beds. Double and crew cab configurations are available, and since both electrification systems are mounted under the chassis, you won’t need to give up bed space or the ability to order their vehicle with bed-delete for service body installations.  Whether you’re looking for a hybrid or plug-in hybrid upfit, our sales managers are here to help.

Plug-in Hybrid Electric System

The XL hybrid-electric system is the simplest and most cost-effective way for fleets to improve MPG and meet sustainability goals without compromising on operations or vehicle performance.  The XLH system saves fuel and reduces emissions through regenerative braking, helping to slow down and propel the vehicle during normal drive cycles. The electric motor assist is smooth and seamless to the driver.

XL Fleet has pioneered a plug-in hybrid system that is revolutionary in its simplicity. In addition to regenerative braking, the XLP features a high-voltage, 15 kWh lithium battery pack that provides a ‘shared propulsion’ with the OEM powertrain to significantly improve MPG and reduce fuel consumption. XLP is compatible with Level 1 and Level 2 charging and has no special maintenance requirements.
