Rivian recently revealed more details about its R1T pickup truck and R1S SUV. Teslarati previously discussed the price and specific trims and/or equipment packages that Rivian will offer for the R1T and R1S, which include the Launch Edition, Adventure Package, and Explore Package.

The Launch Edition, as well as the Adventure and Explore Package R1T and R1S vehicles have an estimated 300+ miles of range per charge, according to Rivian. During the launch of the R1T and R1S back in 2018, Rivian remarked that it would be releasing three battery options for its vehicles: a 105 kWh pack, capable of providing 230+ miles of range; a 135 kWh battery with 300+ miles of range, and a 180 kWh pack which offers 400+ miles of range. It seems Rivian’s early production vehicles will be equipped with its midrange battery. 

The EV truck manufacturer did note, however, that the 400+ mile variant of the R1T will be available beginning in January 2022. It will only offer the 300+ mile R1T variant in 2021 and a longer-range variant with five and/or seven seats will be announced at a later date. A 250+ mile variant, which will be offered at a lower price, will be available for the R1T and R1S at a later date as well.

Rivian’s R1T and R1S line will come standard with Rivian Driver+, the company’s advanced driver-assist system, which promises to a true hands-free driving assistance experience. The system will be capable of over-the-air software updates. 

Similar to Tesla’s Autopilot, Rivian Driver+ will have the capability to automatically steer, adjust speed, and change lanes. However, Rivian noted that the system will only be available on select highways at launch. More areas will be available in the future. Also like Autopilot, Driver+ requires drivers to have their full attention on the road.

Rivian Driver+ features two redundant compute platforms, 12 ultrasonic sensors, and 10 exterior cameras. A suite of 5 radars and high-precision GPS is also equipped on the vehicle, as well as an interior camera designed to monitor driver alertness. 

The specs and features Rivian chose to include in its R1T pickup truck and R1S SUV reflects the kind of automaker it wants to be and they type of vehicles it wants to provide to drivers who like having adventures outdoors, like overlanding. Specific features, like the capability of the R1T’s manual tonneau cover to change into a table, seem specifically tailored for certain pickup truck users. It’s almost as if each Rivian car will be a “bespoke” vehicle.

The success of Rivian’s take on the EV pickup and SUV will be known in due time, most probably after Summer 2021 when deliveries of the R1T and R1S Launch Editions are slated for release.

Tesla confirmed HW3 can’t do Unsupervised FSD but there’s more to the story

Tesla confirmed HW3 vehicles cannot run unsupervised FSD, replacing its free upgrade promise with a discounted trade-in.

Tesla has officially confirmed that early vehicles with its Autopilot Hardware 3 (HW3) will not be capable of unsupervised Full Self-Driving, while extending a path forward for legacy owners through a discounted trade-in program. The announcement came by way of Elon Musk in today’s Tesla Q1 2026 earnings call.

The history here matters. HW3 launched in April 2019, and Tesla sold Full Self-Driving packages to owners on the understanding that the hardware was sufficient for full autonomy. Some owners paid between $8,000 and $15,000 for FSD during that period. For years, as FSD’s AI models grew more demanding, HW3 vehicles fell progressively further behind, eventually landing on FSD v12.6 in January 2025 while AI4 vehicles moved to v13 and then v14. When Musk acknowledged in January 2025 that HW3 simply could not reach unsupervised operation, and alluded to a difficult hardware retrofit.

The near-term offering is more concrete. Tesla’s head of Autopilot Ashok Elluswamy confirmed on today’s call that a V14-lite will be coming to HW3 vehicles in late June, bringing all the V14 features currently running on AI4 hardware. That is a meaningful software update for owners who have been frozen at v12.6 for over a year, and it represents genuine effort to keep older hardware relevant. Unsupervised FSD for vehicles is now targeted for Q4 2026 at the earliest, with Musk describing it as a gradual, geography-limited rollout.

For HW3 owners, the over-the-air V14-lite update is welcomed, and the discounted trade-in path at least acknowledges an old obligation. What happens next with the trade-in pricing will define how this chapter ultimately gets written. If Tesla prices the hardware path fairly, acknowledges what early adopters are owed, and delivers V14-lite on the June timeline it committed to today, it has a real opportunity to convert one of the longest-running sore subjects among early adopters into a loyalty story.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go

Tesla’s Optimus factory in Texas targets 10 million robots yearly, with 5.2 million square feet under construction.

Tesla’s Q1 2026 Update Letter, released today, confirms that first generation Optimus production lines are now well underway at its Fremont, California factory, with a pilot line targeting one million robots per year to start. Of bigger note is a shared aerial image of a large piece of land adjacent to Gigafactory Texas, that Tesla has prominently labeled “Optimus factory site preparation.”

Permit documents show Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas North Campus by the end of 2026, at an estimated construction investment of $5 billion to $10 billion. The longer term production target for that facility is 10 million Optimus units per year. Giga Texas already sits on 2,500 acres with over 10 million square feet of existing factory floor, and the North Campus expansion is being built to support multiple projects, including the dedicated Optimus factory, the Terafab chip fabrication facility (a joint Tesla/SpaceX/xAI venture), a Cybercab test track, road infrastructure, and supporting facilities.

Texas makes strategic sense beyond the existing infrastructure. The state’s tax structure, lower labor costs relative to California, and the proximity to Tesla’s AI training cluster Cortex 1 and 2, both located at Giga Texas and now totaling over 230,000 H100 equivalent GPUs, means the Optimus software stack and the factory producing the hardware will share the same campus. Tesla’s Q1 report also confirmed completion of the AI5 chip tape out in April, the inference processor designed specifically to power Optimus units in the field.

As Teslarati reported, the Texas facility is intended to house Optimus V4 production at full scale. Musk told the World Economic Forum in January that Tesla plans to sell Optimus to the public by end of 2027 at a price between $20,000 and $30,000, stating, “I think everyone on earth is going to have one and want one.” He has previously pegged long term demand for general purpose humanoid robots at over 20 billion units globally, citing both consumer and industrial use cases.

Tesla (TSLA) Q1 2026 earnings results: beat on EPS and revenues

Published

on

Credit: Tesla

Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.

The earnings results come after Tesla reported a miss on vehicle deliveries for the first quarter, delivering 358,023 vehicles and building 408,386 cars during the three-month span.

As Tesla transitions more toward AI and sees itself as less of a car company, expectations for deliveries will begin to become less of a central point in the consensus of how the quarter is perceived.

Nevertheless, Tesla is leaning on its strong foundation as a car company to carry forward its AI ambitions. The first quarter is a good ground layer for the rest of the year.

Tesla Q1 2026 Earnings Results

Tesla’s Earnings Results are as follows:

  • Non-GAAP EPS – $0.41 Reported vs. $0.36 Expected
  • Revenues – $22.387 billion vs. $22.35 billion Expected
  • Free Cash Flow – $1.444 billion
  • Profit – $4.72 billion

Tesla beat analyst expectations, so it will be interesting to see how the stock responds. IN the past, we’ve seen Tesla beat analyst expectations considerably, followed by a sharp drop in stock price.

On the same token, we’ve seen Tesla miss and the stock price go up the following trading session.

Tesla will hold its Q1 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
