Introduction: The Transition from Gas to Electric – A Hummer’s Journey
The iconic Hummer, once known for its hefty fuel consumption, has taken a giant leap into the future with the 2023 GMC Hummer EV 3X Pickup.
Despite its transformation into an electric vehicle (EV), questions linger: Does this switch make the Hummer a model of efficiency?
The Ultium Battery – A Game Changer in EV Technology
General Motors’ revolutionary Ultium battery technology propels the Hummer EV into the limelight.
This groundbreaking platform, first showcased in the 2023 Hummer EV Edition 1 Pickup, marks GMC’s initial foray into electric vehicles.
The Ultium battery’s unique design, featuring versatile pouch cells that can be positioned vertically or horizontally, allows for a substantial 205-kWh capacity in the Hummer EV.
In the realm of EVs, especially those we evaluated in 2023, this capacity is unparalleled, dwarfing its closest competitor, the Rivian R1T, by a significant margin.
GMC Hummer EV 3X’s Unmatched Fast-Charging Capabilities
Charging efficiency is a critical aspect of any EV, and the Hummer EV 3X Pickup excels in this arena.
It supports both 400 volts and 800 volts DC fast-charging, with a staggering 350 kW peak rate.
This makes the Hummer EV compatible with nearly all DC fast-chargers, tapping into the fastest available.
Additionally, it accommodates Level 1 and Level 2 AC charging, offering versatility for different charging scenarios.
Innovative Battery Pre-conditioning and Real-World Charging Performance
Preparing the Hummer EV for optimal charging involves a pre-conditioning process, easily initiated through the onboard navigation system.
This process, while standard in many EVs, is executed efficiently in the Hummer, taking approximately 40 minutes to precondition the battery for charging.
During our tests, the Hummer EV 3X demonstrated a peak charging speed of 264 kW, slightly below GMC’s claim, but still impressive.
It achieved a full charge in just 75 minutes, showcasing its robust fast-charging capability.
Sustaining High Charging Rates: A Standout Feature
What sets the Hummer EV apart is its ability to maintain high charging rates over an extended period.
It sustained over 200 kW for 27 minutes and remained above 100 kW for an hour, a feat many EVs can’t match.
This rapid charging capability significantly reduces downtime, making the Hummer EV a more practical option for long-distance travel.
Exploring the Real-World Range of the GMC Hummer EV
The Hummer EV’s range is a complex blend of impressive distance capability and efficiency challenges.
In our MotorTrend Road-Trip Range test, the Hummer EV achieved an exceptional 310 miles, only 13% below GMC’s estimate.
This range surpasses other competitors like the Rivian R1T and the Ford F-150 Lightning Lariat, solidifying the Hummer EV’s position as a leader in EV range.
Efficiency and Cost Analysis: A Closer Look
While the Hummer EV’s range is commendable, its efficiency metrics present a different picture.
With a calculated efficiency of 1.5 miles per kWh, the Hummer EV’s performance is affected by its size and design.
The substantial cost of public charging, exceeding $100 for a full charge, is a consideration for potential buyers, although home charging presents a more economical alternative.
Conclusion: The Hummer EV’s Place in the EV Landscape
The 2023 GMC Hummer EV 3X Pickup represents a bold approach to solving the EV range dilemma.
With its massive battery and robust charging capabilities, it sets a precedent for future electric vehicles.
While it may not be the most cost-effective or efficient option available, the Hummer EV showcases the potential for innovative battery technology and fast charging in transforming the EV experience.
As General Motors continues to evolve its electric lineup, the lessons learned from the Hummer EV will undoubtedly influence the development of more efficient and sustainable vehicles.
