With the ongoing transition in the automobile industry to electric propulsion, the Hummer has introduced one of its kind electric best off-roaders, has the comfort of a luxury sedan and has the speed of a sports car. And it has a truck bed. known as the best Sports truck by the company, it is yet worth every penny.
The GMC Hummer EV is finally making its way to dealerships on the East Coast, sporting its massive size as it sits alongside a GMC Yukon, one of the automaker’s largest sport utility vehicles.
After being in development for several years, the GMC Hummer EV is finally making its way to dealerships on the East Coast.
The major takeaways of the GMC Hummer EV have been the revolutionary and advanced systems, including its Ultium battery system, it appears details on the initial builds are relatively slim. After all, the Hummer EV was GM’s second-most-produced electric vehicle in December 2021. The automaker has dealt with widespread battery issues with its Chevrolet Bolt EV, which has been its keystone EV for a decade.
Undoubtedly, the rated range of the Hummer EV, 329 miles (529 km), is also impressive. Especially considering how much heft GM’s three-motor e4WD drive system is the biggest takeaway of the automobile. It has been a motivation in a way that the Hummer EV is capable of producing acceleration numbers that would have embarrassed supercars of a few decades ago. Watching a Hummer launch from a standing start to 60 mph (96.5 kph) in roughly three seconds while wearing 35-inch (889-mm) Goodyear Wrangler all-terrain tires is like watching Usain Bolt set the 100-meter world record in Wellingtons.
Hummer’s evolution as an EV began with GM’s BT1 platform and Ultium drive system. which will underpin future EV products from the company. GM’s representatives were excited about the scalability that this platform offers them for future products. GM states that its Ultium batteries are unique in the industry because of their large-format, pouch-style cells, which can be stacked vertically or horizontally inside the battery pack.
The pack in the Edition 1 Hummer consists of two layers of vertical cell modules, which will be used to produce a combined 24-module pack. The pack is mounted in the centre and lowest point of the vehicle platform. This not only keeps the centre of gravity as low as possible but as GM points out, enables very short front and rear overhang (34.7 inches or 881 mm front, 46.5 inches or 1181 mm rear) as well as an impressive break-over angle (25.4 degrees in terrain mode).
The Ultrium cells are comprised of a mixture of nickel, cobalt, manganese and aluminium, though GM claims that these units use 70% less cobalt than their previous generation of EVs.
The Hummer EV will also be the first vehicle in GM’s lineup to feature its wireless battery management system, which monitors the battery cell groups for optimal performance and battery longevity. The Hummer EV will also be capable of 350-kW DC fast charging, thanks to its unique ability to switch its battery pack from its native 400 volts to 800 volts when fast charging. This is enabled by the pack’s disconnect unit, which GM states can switch the battery from parallel to series operation, thereby resulting in 100 miles (161 km) of additional range during a ten-minute charge.
Another feature that may go unappreciated is the one-pedal drive mode. The Hummer is the first GMC vehicle to offer this feature, which is both equally useful in rush hour traffic and in the woods. Enabling one pedal drive cranks up the regen braking to the point that the driver can navigate just about any trip with just the accelerator pedal.
The Hummer’s drive system is also responsible for its off-road capabilities. The single-motor front drive unit’s electronic lockable differential can deliver up to 100% of the motor torque to one wheel. The two rear motors independently power each wheel through a fixed gear ratio (10.5:1) with the capability to vary torque output to each wheel.
