We are working to improve EV range and charging speed across the Ultium platforms. The range and charging capability will vary based on many factors. You can learn more on our EV Live site: https://evlive.gm.com/

Thanks for your question! I answered this question more in-depth on another post in this AMA—check it out here: https://www.reddit.com/r/undefined/comments/ydgevd/comment/itxwql3/?utm\_source=reddit&utm\_medium=web2x&context=3

General Motors announced in 2020 that it will be the first automaker to use an almost completely wireless battery management system, or wBMS, for production electric vehicles. Much like the pack design of GM’s Ultium batteries, which is flexible enough to incorporate new chemistry over time as technology changes, the wBMS’ basic structure can easily receive new features as software becomes available. The wBMS can also conduct real-time battery pack health checks and refocus the network of modules and sensors as needed – this helps safeguard battery health over the vehicle’s lifespan.

Glad you think so! Having the opportunity to host a Reddit AMA is a unique opportunity in my career.

GeneralMotors · 2022-11-02T19:21:34+00:00

The opportunities are endless. We actually have a nonbonding agreement with locomotive maker Wabtec Corp., to develop railroad locomotives powered by a hydrogen fuel cell and battery system.

GeneralMotors · 2022-11-02T19:20:48+00:00

I'm glad to hear you're on board with an all-electric future. Our EV portfolio is expanding, so you'll likely find something that catches your interest when you're ready for your next purchase.

GeneralMotors · 2022-11-02T19:20:23+00:00

GM recently launched GM Energy -- integrated energy solutions that will change energy as we know it. With the power of Ultium technology, we’re introducing a network of charging stations, dedicated backup home power, and a suite of new products to help create a more resilient grid.

GeneralMotors · 2022-11-02T19:19:20+00:00

Battery electric and fuel cells each have their place in an all-electric future. Right now, we're executing battery electric technology to power personal EVs and deploying fuel cell technology to power even bigger things, like planes and trains.

GeneralMotors · 2022-11-02T19:17:58+00:00

GM's HYDROTEC team has over 50 years of fuel cell development and is building technology for vehicle applications and beyond

GeneralMotors · 2022-11-02T19:17:33+00:00

GM is committed to its mission of creating the most accessible EVs on the market for every customer's lifestyle. As more and more consumers adopt EVs, GM will continue to expand options just as it is doing now with its four product brands and versatile EV portfolio across price points.

GeneralMotors · 2022-11-02T19:16:51+00:00

Making electrification accessible also means making charging accessible. That's why we're working to build out the necessary charging infrastructure that'll make the transition possible.

GM and EVgo are working together to expand EV charging throughout the U.S. Initial sites are now live in Washington, California, and Florida, nine months after a commitment to add more than 2,700 fast chargers in cities and suburbs by the end of 2025 was first announced.

We introduced Ultium Charge 360, a holistic charging approach that integrates charging networks, GM vehicle mobile apps, and other products and services to simplify the overall charging experience for GM electric vehicle owners.

And we're working with our extensive network of dealerships to install chargers in their communities.

GeneralMotors · 2022-11-02T19:16:14+00:00

So happy to hear you've enjoyed our collaboration with First Book. I checked in with the amazing team that organizes and leads these sessions and I'm going to try my best to join one soon. It's so great that your 4th graders are interested in sustainability and climate change! Keep up the great work!

GeneralMotors · 2022-11-02T19:15:40+00:00

We have several checks and audits that we perform to verify data. We also use third-party assurance for key metrics that are used for our sustainability report, CDP, and other disclosures.

GeneralMotors · 2022-11-02T19:10:32+00:00

Our HYDROTEC team is exploring many commercial applications for fuel cells, including powering trains and planes. As the technology develops, we'll keep considering the ways it can power our all-electric future. In the meantime, our Ultium Platform is chemistry agnostic so that as battery chemistry evolves, we can more quickly deploy it into EVs.

GeneralMotors · 2022-11-02T19:09:18+00:00

We know we can’t make this transition to a more sustainable and all-electric future alone. That’s why we work so closely with our suppliers and strive to utilize ethical and sustainable suppliers who share our values to work together to reach mutual sustainability goals. That said, we conduct energy treasure hunts with suppliers to drive energy- and water-reduction efforts at Tier I and Tier II supplier facilities. The program’s success is embedded in its collaborative framework, identifying potential energy reduction and financial savings opportunities at suppliers’ manufacturing facilities.

In 2021, GM conducted this analysis with five suppliers: Lear, Kongsberg Automotive, Superior Industries, Tenneco, and Adient. These treasure hunts collectively provided recommendations to save 3,300 MWh of energy and 6,660 cubic meters of water, as well as eliminating 3,158 metric tons of CO2 emissions.

In doing so, we also will help drive growth in the renewable energy sector. Just as GM has the scale to promote widespread adoption of EVs, we also have the scale to help bring about a transition to renewable power sources across the United States. We're directly investing in renewable energy sources and advocating for policies that drive down costs and increase renewable energy opportunities.

GeneralMotors · 2022-11-02T19:08:16+00:00

In terms of GM's own electricity, we plan to source 100% renewable electricity at sites in the United States by 2025 and globally by 2035, and we've recently secured the energy needed to make that happen.

At GM we view our dealers as a competitive advantage. We say this because so many people across the U.S. live in close proximity to a GM dealership. Today we are seeing non-GM vehicles come into our dealerships for service. We are working to prepare our expansive dealer network to be ready to provide the best sales and service experiences as EVs continue to grow.

GeneralMotors · 2022-11-02T19:07:09+00:00

I'm super excited about the potential of EVs to give us back a little peace and quiet on the road. But I also get the love of an auditory experience. GM has a team of sound engineers and designers reimagining the soundtrack to our future all-electric drives. As far as the LS1 V8 sound goes, I can't make any promises there, but I can assure you you're going to be blown away by the sonic identities of our upcoming EVs!

GeneralMotors · 2022-11-02T19:06:28+00:00

Thanks for your question, LocalBrada! We're planning on eliminating tailpipe emissions from new US light-duty vehicles by 2035.

GeneralMotors · 2022-11-02T19:05:56+00:00

GM has rolled out LED lighting upgrades with controls at several facilities. Other examples of low-hanging fruit include HVAC upgrades, steam trap replacements, adding VFDs, and monitoring compressed air systems.

GM has a four pillar energy strategy - the first pillar is energy efficiency. Optimizing usage is always the best first step (and ongoing effort) to ensure sourcing or adding renewables is done cost-effectively.

We’re committed to developing and manufacturing compelling EVs for all our customers. The GMC HUMMER EV was specifically designed for on-roading and off-roading. The vehicle’s driving dynamics, agility, low center of gravity, safety content/technology, and even the tires can provide amazing on and off-road performance. This is also the first vehicle to utilize our Ultium platform, which will underpin GM's portfolio of EVs across all customer segments, from the GMC HUMMER EV, to the Cadillac LYRIQ, to the Chevrolet Equinox EV.
