2026 GMC Hummer EV: The All-Electric Supertruck

The 2026 GMC Hummer EV represents one of the most ambitious transitions in the modern automotive industry: the evolution of an iconic, fuel-intensive vehicle into a fully electric, high-performance platform. Built on General Motors’ Ultium architecture, the Hummer EV is positioned as a full-size electric pickup and SUV that prioritizes torque, off-road capability, advanced software systems, and large-capacity battery technology.

This page provides a detailed, informational overview of the 2026 GMC Hummer EV, focusing on technical specifications, platform design, drivetrain options, charging, interior technology, safety systems, and how the vehicle fits into the broader EV leasing landscape. It is intended for drivers researching a 2026 GMC Hummer EV for lease and for readers seeking a deeper understanding of next-generation electric trucks.

Overview of the 2026 GMC Hummer EV Platform

The Hummer EV is built on GM’s Ultium platform, a scalable EV architecture designed to support large battery packs, dual- and tri-motor configurations, and software-defined vehicle features.

Unlike traditional electric SUVs, the Hummer EV is engineered to operate in extreme conditions, including rock crawling, steep inclines, and low-traction terrain. The 2026 model year continues to refine this approach with incremental improvements in software calibration, energy management, and driver-assistance features.

Key characteristics of the platform include:

• High-voltage Ultium battery system

• Independent front and rear suspension

• Rear-wheel steering capability

• Over-the-air (OTA) software updates

• Advanced torque vectoring

Powertrain and Performance Specifications

The 2026 GMC Hummer EV is available in multiple drivetrain configurations depending on body style and trim. These configurations are designed to balance performance, efficiency, and off-road control.

Electric Motors

• Dual-motor AWD (available on select trims)

• Tri-motor AWD (performance-focused configuration)

The tri-motor setup delivers instantaneous torque to all four wheels, enabling controlled movement on uneven surfaces and rapid acceleration on paved roads.

Estimated Performance Metrics

• Horsepower: Up to approximately 1,000 hp (tri-motor configuration)

• Torque: Estimated 11,500 lb-ft (wheel torque, manufacturer-reported)

• 0–60 mph: Approximately 3.5 seconds (depending on configuration)

These figures place the Hummer EV among the highest-performing electric trucks currently available.

Battery Capacity, Range, and Charging

Battery System

The Ultium battery pack in the 2026 GMC Hummer EV uses large-format pouch cells arranged to support high energy density and durability.

• Estimated capacity: 170–200+ kWh (depending on configuration)

• Cooling: Liquid thermal management system

• Chemistry: Nickel-rich lithium-ion cells

Driving Range

Estimated EPA range varies by body style and drivetrain:

• Pickup: ~350 miles (dual-motor)

• SUV: ~300–320 miles (tri-motor)

Real-world range may vary based on driving conditions, temperature, terrain, and payload.

Charging Capabilities

• DC fast charging: Up to 350 kW

• Range added: Approximately 100 miles in ~10–12 minutes (optimal conditions)

• AC charging: Level 2 home charging compatible

Fast-charging capability is a key consideration for drivers planning to lease a 2026 GMC Hummer EV, particularly in urban and regional driving environments.
