The GMC Hummer EV Pickup holds the title as the heaviest electric vehicle, weighing in at a substantial 9,063 pounds. Its robust construction and large battery pack contribute significantly to its curb weight, making it one of the most formidable EVs on the market.
Electric vehicles often carry considerable weight due to their expansive battery packs, which are essential for providing sufficient range and power. This weight impacts various aspects of the vehicle, from its driving dynamics to its efficiency and even infrastructure requirements.
Understanding EV Weights
The curb weight of an electric vehicle includes the standard equipment, all necessary fluids, and a full tank of fuel (or a fully charged battery in the case of EVs), but without passengers or cargo. This metric is crucial for understanding a vehicle's overall mass.
Here's a comparison of some of the heaviest electric vehicles currently available:
| EV Model | Length (inches) | Curb Weight (pounds) |
|---|---|---|
| GMC Hummer EV Pickup | 216.8 | 9,063 |
| Rivian R1T | 217.1 | 7,148 |
| Rivian R1S | 200.8 | 6,986 |
| Tesla Cybertruck | 223.7 | 6,603 |
Weights are approximate and can vary based on trim levels and optional equipment.
Why are Electric Vehicles So Heavy?
Several factors contribute to the significant weight of modern electric vehicles:
- Battery Packs: The primary reason for the increased weight is the large, high-capacity lithium-ion battery packs required to power the vehicle and provide a competitive driving range. These batteries are dense and contribute thousands of pounds to the overall mass.
- Structural Reinforcement: To protect these heavy battery packs and ensure passenger safety, EV platforms often feature robust underbody protection and reinforced structures, adding further weight.
- Electric Motors: While generally lighter than internal combustion engines, EVs typically use multiple electric motors (often one per axle for all-wheel drive), which add to the total weight.
- Luxuries and Technology: Many early or flagship EVs are designed as premium vehicles, incorporating advanced technology, sound-deadening materials, and luxury features that naturally increase the vehicle's mass.
The trend towards larger, more capable electric trucks and SUVs also naturally leads to heavier vehicles, as they are designed to offer more utility, space, and off-road capability, often requiring larger batteries and more robust chassis.
