General Motors has tried to cast Hummer in a greener light before

Rumors claim General Motors will resurrect the Hummer name on an electric pickup truck by 2022, and GM allegedly will preview the model with an ad starring basketball star LeBron James during the 2020 Super Bowl. If accurate, the move would represent a stunning 180-degree turn for a nameplate long associated with war-like gas-guzzlers. It wouldn't be the first time the automaker has tried to cast Hummer in a greener light, however. In 2004, when mass electrification looked as realistic as George Jetson's flying car, Hummer collaborated with Quantum Technologies to build a one-off H2 SUT named H2H powered by hydrogen. Engineers modified the stock H2's 6.0-liter V8 to run on compressed hydrogen stored in three carbon fiber tanks, and added a supercharger to offset the loss of power. The eight-cylinder made 180 horsepower, compared to 325 horsepower in the gasoline-powered model, and the truck's 12-pound hydrogen storage capacity gave it a 60-mile range. "The H2H was created for two purposes. It brings focus and attention to the journey to a hydrogen economy, and it will provide GM with key learnings on hydrogen storage, hydrogen delivery systems, and hydrogen refueling infrastructure development," explained Elizabeth Lowery, the company's then-vice president of environment and energy. She emphasized the H2H's experimental vocation and said there were no plans to bring it to production. Actor, then-California governor, and devout Hummer fan Arnold Schwarzenegger celebrated the H2H as a vision of the future after taking it for a spin. It didn't have much of a future, as it turns out, and it remained a prototype. Fast-forward to 2009, less than a year before Hummer shut down after the Chinese government vetoed a proposed sale to Sichuan Tengzhong Heavy Industrial Machinery Company. General Motors teetered on the brink of bankruptcy, it had much bigger worries than Hummer's fuel economy, so the task of making a greener truck fell into the lap of suppliers. FEV and Raser joined forces to build a plug-in hybrid prototype based on the H3. Its powertrain was built around a turbocharged, 2.0-liter EcoTec engine related to the unit found in the Chevrolet HHR SS and the Pontiac Solstice GXP, among other cars. In this application, it powered a 100-kilowatt generator that zapped a 268-horsepower electric motor into motion. Output traveled through the H3's stock four-speed automatic transmission and four-wheel-drive system, including the transfer case.

Mil-Spec built a one-off, track-ready Hummer H1

Mil-Spec is one of the latest companies looking for success with restored and modified versions of iconic vehicles. Rather than Porsche 911s or '60s trucks and SUVs, its canvases are Hummer H1s. The customer vehicles are big, brash off-road machines, but that's not all the company is capable of. We recently learned that the crew over there built a Hummer H1 meant for race track use, and it is amazing. The base vehicle is a four-door convertible pickup truck, and Mil-Spec thoroughly changed the suspension. It has custom coilovers with stiff springs, and the entire suspension geometry has been revised. Overall, it was lowered a stunning seven inches compared with a stock H1. The H1's in-board brakes now feature six-piston brake calipers, and the wheels are wrapped in low-profile Pirelli P-Zero tires. Also impressive is the fact that the truck still has a part-time four-wheel-drive system. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Under the hood is a 6.6-liter Duramax diesel V8 similar to that in the customer models. But this one has been tuned all the way up to 800 horsepower and 1,500 pound-feet of torque. This engine also plays a role in this truck's origins. Apparently the truck was used for final powertrain testing and development. But it was also built to highlight the company's capabilities. If you want one of these, well, you can't have one. At least not yet. We asked a Mil-Spec representative, and he told us that there are no plans for offering track-oriented H1s. That's understandable, since the company is still working through building and selling its initial run of 12 off-road-ready vehicles. He did say the truck has generated a lot of interest, though. So, maybe when the company has time, and if a really wealthy buyer really wanted one, maybe the Mil-Spec could work something out. But at least in the meantime, the company is sticking to tall, chunky-tired H1s. Related Video:

At the time of the Hummer launch in 1992, America's mood was pretty good, we'd pushed Iraq out of Kuwait, and the economy headed for an uptick. It may not have been the best of times, but it was the perfect time to introduce a thirsty, in-your-face SUV. Regrettably, in the following decade we suffered 9/11, were waging two wars, and then the economic downturn struck. And despite the relative sanity offered by the smaller H3, GM entered into Chapter 11 in 2009 and killed off Hummer. With relatively few sold in the five model years it was offered, finding a clean H3 is a challenge. We like the H3's smaller footprint - relative to the huge H1 and Tahoe-based H2 - and the quirkiness of an inline 5-cylinder matched to a 5-speed manual. With this for-sale example, offered in Arkansas, you'll find mileage perfectly reasonable for a vehicle now 12 years old, and it looks clean. Despite its ruggedness, we'd get a pre-purchase inspection and negotiate on an asking price significantly above book. Related Video: This content is hosted by a third party.
