Rivian R1T has the highest range for an electric truck with a 328-mile EPA estimate
The Rivian R1T is now the electric truck with the most range after receiving a 328-mile range estimate from the Environmental Protection Agency (EPA).
The 2023 Rivian R1T with 21-inch wheels received an EPA range estimate of 328 for the Quad-Motor with a Large battery pack configuration. 2023 Rivian R1T owners who ordered the Quad-motor with a Large battery pack configuration can save up to $3,500 in fuel costs over the next 5 years.
For comparison, the 2023 R1T with 22-inch wheels has an EPA estimated range of 303 miles, with calculated fuel savings of $3,000 over 5 years. While the 2022 Rivian R1T with 20-inch wheels saves owners up to $2,750 in fuel costs in 5 years with an EPA estimated range of 289 miles.
Recently, Rivian sent letters to reservation holders who ordered Quad-Motor R1Ts with the Max battery pack. The company advised reservation holders to switch to Quad-Motor R1Ts with Large battery packs if they want to accept delivery in early 2023.
Rivian informed R1T reservation holders that the Quad-Motor R1T with Max battery pack would not be available beginning in 2023. The Max battery pack will only be available with Dual-Motor R1T orders next year.
Rivian offers three battery options for R1T orders: Standard, Large, and Max packs. The Standard pack has an estimated range of 260+ miles, while the Max pack has a range of up to 400 miles. In the middle is Rivian’s Large pack, which has an EPA estimate of 328 miles. The Max pack costs an additional $16,000 in the U.S. and $21,750 in Canada, while the Large pack costs $6,000 in the United States and $8,250 in Canada.

Rivian R1T Tax Breaks
According to the EPA, the 2022 Rivian R1T—with an MSRP between $63,500 and $73,000—may qualify for tax breaks. The Inflation Reduction Act of 2022 introduced a federal tax credit of up to $7,500 on electric vehicles that meet specific government guidelines.
The EPA offered some advice to R1T reservation holders that might help them get tax breaks on 2022 R1T orders.
“If you entered into a written binding contract to purchase a new qualifying electric vehicle before August 16, 2022, but do not take possession of the vehicle until on or after August 16, 2022 (for example, because the vehicle has not been delivered), you may claim the EV credit based on the rules that were in effect before August 16, 2022,” noted the agency.
“If you purchased a qualifying electric vehicle on or before August 16, 2022, and placed it in service before January 1, 2023, you may claim the EV credit based on the rules that were in effect before August 16, 2022,” it advised.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo
“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.
NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance.
More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system.
Jensen Huang’s praise for Tesla FSD
Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”
During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:
“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.
“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said.
Nvidia’s platform approach vs Tesla’s integration
Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.
“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.
He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.
“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”
He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.

xAI’s turbine deal details
News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.
As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X.
xAI’s ambitions
Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”
The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.
