Since they released their Super Bowl commercials, GM has been relatively quiet about the specs of the new Hummer EV.

With that being said there are a few things we know about the Hummer EV so far.
  • Release Date: May 20, 2020
  • 1,000 horsepower
  • 11,500 lb/ft of torque
  • 0-97 km/h (0-60 mph) in 3 seconds
  • It will offer one, two, and three-motor powertrain options
  • It will be build at GM's Detroit-Hamtramck assembly plant in Michigan
Does anyone have any guesses for what the Hummer's other specs will be?

We have some new info from General Motors about the Hummer's batteries!

Ultium Batteries and Propulsion System Highlights
  • GM’s new Ultium batteries are unique in the industry because the large-format, pouch-style cells can be stacked vertically or horizontally inside the battery pack. This allows engineers to optimize battery energy storage and layout for each vehicle design.
  • Ultium energy options range from 50 to 200 kWh, which could enable a GM-estimated range up to 400 miles or more on a full charge with 0 to 60 mph acceleration as low as 3 seconds. Motors designed in-house will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications.
  • Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400-volt battery packs and up to 200 kW fast-charging capability while our truck platform will have 800-volt battery packs and 350 kW fast-charging capability.
GM’s flexible, modular approach to EV development will drive significant economies of scale and create new revenue opportunities, including:
  • Continuous Improvement in Battery Costs: GM’s joint venture with LG Chem will drive battery cell costs below $100/kWh. The cells use a proprietary low cobalt chemistry and ongoing technological and manufacturing breakthroughs will drive costs even lower.
  • Flexibility: GM’s all-new global platform is flexible enough to build a wide range of trucks, SUVs, crossovers, cars and commercial vehicles with outstanding design, performance, packaging, range and affordability.
  • Capital Efficiency: GM can spend less capital to scale its EV business because it is able to leverage existing property, including land, buildings, tools and production equipment such as body shops and paint shops.
  • Complexity Reduction: The vehicle and propulsion systems were designed together to minimize complexity and part counts beyond today’s EVs, which are less complex than conventional vehicles powered by internal combustion engines. For example, GM plans 19 different battery and drive unit configurations initially, compared with 550 internal combustion powertrain combinations available today.
  • Rising Customer Acceptance: Third-party forecasters expect U.S. EV volumes to more than double from 2025 to 2030 to about 3 million units on average. GM believes volumes could be materially higher as more EVs are launched in popular segments, charging networks grow and the total cost of ownership to consumers continues to fall.
  • New Sources of Revenue: By vertically integrating the manufacture of battery cells, the company can reach beyond its own fleet and license technology to others.
The first generation of GM’s future EV program will be profitable. The initial programs will pave the way for further accretive growth. GM’s technology can be scaled to meet customer demand much higher than the more than 1 million global sales the company expects mid-decade.

I got to be honest I am never impressed with the 0-60 numbers for electric vehicles. We all know electric cars have massive torque. I have a 2007 hummer and it is not fast but it can climb any hill, drive through any weather, and given it's size surprisingly turn on a dime. In my opinion that is what new Hummer owners will be looking at. If I want fast I'll buy a sports car. I am curious whether it will have the same sure footedness and iconic presence I enjoy with my Hummer

That's definitely the million dollar question, whether or not it can perform off-road like a proper Hummer. At the very least the torque will help it get through any tough spots.

From what I've heard of the new BT1 platform, it's going to be extremely rugged. GM said that, at least on the more expensive Hummers (probably the dual- and tri-motor variants), there will be an air suspension setup all around, and of course, the platform will have independent suspension all around as well (like the original Hummer), across the entire range. With the IRS, air ride and battery pack tucked up into the base of the chassis, ground clearance should be excellent. If the frame is as good as they claim, with that suspension setup and electric torque, it should be pretty formidable off the beaten path. Maybe not as good as a live-axle truck like the Wrangler, but pretty damn good regardless.

That's definitely a winning combination. Since the Hummer is basically the new face of GM's EV line they really can't skimp out on performance, on and off-road.

Agreed 100%, Oakwood. I think we're about to learn a whole lot about GM and its trajectory going forward from both the Hummers and the Lyriq SUV. GM is without question trying to reinvent themselves in a way they haven't since the early 1900's...this is a HUGE gamble, but if it pays off...they could once again become the most powerful car company in the world down the line.
