GM responds to study about Hummer EV's high emissions

The study showed that smaller and lighter EVs will be more efficient than something like the Hummer EV.

According to a recent study by ACEEE (American Council for an Energy-Efficiency Economy), the GMC Hummer EV produces more emissions than an IC-engine powered sedan - Chevy Malibu.

As per the reports, the study found that the Hummer EV was responsible for 341 grams of CO2 per mile, which is higher than Chevy Malibu's 320 grams of CO2 emissions over a mile. The high emissions from the Hummer EV are mainly attributed to the fossil fuels in the US power grid, which due to the vehicle's size and weight is comparable to the pollution levels of many IC-engine vehicles.

The study showed that smaller and lighter EVs will be more efficient than something like the Hummer EV. The smaller EVs will also require smaller battery packs, translating to less mining of rare earth metals - making them more eco-friendly on most fronts.

Now, General Motors has responded to the study stating that electric Hummer's inefficiency is because of the fact that it is a "Performance-oriented EV" and is built to go fast, rather than be frugal. The Hummer EV comes with a massive 212 kWh battery pack with 330 miles (531 km) of range. However, the electric SUV packs 1000 BHP and is capable of sprinting from 0 - 100 km/h in 3 seconds, which on a 4-tonne off-road electric pick-up truck is massively impressive.

The American carmaker also goes on to state that the study ignores the real-world importance of the Hummer EV and how the performance EV attracts customers to the electric vehicle segment. The spokesperson of GM said that 75% of customers who have reserved the Hummer EV have never owned an EV, and many are or were pick-up truck owners.
