Body Style and Size Segment

Occupying the full-size electric supertruck and premium large SUV segments, the Hummer EV is an absolute behemoth. The pickup variant stretches over 5.5 meters long and 2.2 meters wide, demanding presence on any road.

Platform Architecture

Built on GM’s revolutionary Ultium Platform, it utilizes a dual-stack, 24-module battery pack featuring Lithium-ion NCMA chemistry with a massive 212.7 kWh usable capacity. Operating on a true 800V architecture, it supports DC fast charging up to 350 kW. Despite its 4.1-tonne weight, the 3-motor version unleashes a 0-100 km/h (0-62 mph) sprint in just 3.0 seconds via Watts to Freedom mode. This raw power yields an estimated WLTP range of 613 km (381 miles), though efficiency is a modest 2.8 km per kW (1.8 miles per kW).

Technical Capabilities

Equipped with GM’s advanced Super Cruise for hands-free highway driving and an UltraVision array with 18 underbody cameras. It features revolutionary 4-wheel steering with CrabWalk capability and Extract Mode, lifting the air suspension by 15 cm. Crucially, it supports bidirectional charging, offering V2L (via the Power Station generator), V2H emergency home backup, and V2G grid support.

Quality & Warranty

The cabin balances rugged utility with premium digital layouts, utilizing durable, easy-to-clean synthetic materials and rugged rubber flooring. Storage is exceptional, highlighted by the massive front eTrunk (322 liters) and versatile rear bed or SUV cargo holds. Protection includes a 5-year/100,000-km bumper-to-bumper warranty and an 8-year/160,000-km battery warranty.

App Functionality

Managed via the myGMC App, drivers can pre-condition the cabin, monitor Ultium charging, and activate the digital key. Crucially, it integrates seamlessly with the GM Energy ecosystem to manage home backup power flow.

3 Pros and 3 Cons

• Pros: Mind-boggling acceleration, peerless off-road maneuverability (CrabWalk), and massive bidirectional backup capacity.

• Cons: Enormous weight and footprint, low energy efficiency, and restricted availability outside North America.

The Hummer EV is the ultimate “weekend warrior” machine for those who want luxury, extreme performance, and off-road dominance.

It competes with the Rivian R1T and Tesla Cybertruck.

Currently available primarily in North America, it is aimed at buyers seeking the ultimate adventure vehicle rather than an everyday commuter.
