Rivian has officially launched the next-generation R1S and R1T, new versions of the company’s flagship electric vehicles.
“We continue to evolve our flagship R1 vehicles,” CEO RJ Scaringe said, “offering quality and performance without compromise. Our revamped R1S and R1T push the technical boundaries further, creating our most capable products to date.”
Rivian aimed to refine and improve performance, design, range, and overall ownership experience with the new R1T and R1S, bringing everything from new drivetrains to new interior aesthetics to the EVs without compromising any of the features that owners loved about the first generation.
Additionally, Rivian is rolling out its new Autonomy Platform, which was developed in-house and utilizes eleven internally developed cameras along with five radars that perform over 250 trillion operations per second.
“For most owners, their R1 Gen 2 will be the most powerful computer that they own,” VP of Autonomy and AI for Rivian, James Philbin, said.
Let’s dive into some of the improvements Rivian has employed:
Performance
Rivian’s next-gen R1 platform now features more power, performance, and range, all stemming from a new drive unit offered in its Tri and Quad-Motor configurations. Dual-Motor has not gone anywhere either, and still offers great performance metrics:
- Dual-Motor Our Dual-Motor delivers incredible all-wheel drive capability along with 665 horsepower and 0–60 mph in as quick as 3.4 seconds for the Performance variant
- Tri-Motor Our all-new 850 horsepower Tri-Motor packs two motors in the rear and one in front for a blend of exceptional power and range. The Tri-Motor R1T delivers 0–60 mph in 2.9 seconds while offering an estimated range of 380 miles. In Conserve Mode, the estimated range is up to 410 miles.
- Quad-Motor For peak adventure, our new 1,025 horsepower Quad-Motor delivers 0–60 mph in less than 2.5 seconds in R1T — and ¼ mile in 10.5 seconds — with a staggering 1,198 lb-ft of torque when using Launch Mode. 60–80 mph acceleration is 1.5 seconds, with incredible torque control at each wheel for superior on-road performance and off-road capability.
Ride and Handling
Rivian also focused on the ride and handling experience in the R1 lineup for this second-generation vehicle launch. The suspension system has been fully re-engineered, improving on what customers called a “sport-tuned feel” in the first-generation EVs. Rivian decided to go with a “smoother” ride for the new R1T and R1S, which is adjustable to ensure comfortable on and off-road capabilities.
Vehicle equipment has also been refined. Rivian developed new wheels and fitted them with new tires, including a redesigned 22″ aerodynamic wheel design and Pirelli-developed tires to increase range.
For Performance, Rivian is going with an Ultra-High-Performance Michelin tire that will be available on the Quad-Motor configurations. Additionally, for a “well-rounded” experience, Goodyear has a 20″ ADV tire that offers “balanced all-around capability with the rolling-resistance of an all-season,” and comes standard.
Range and Batteries
Three battery pack sizes will still be offered by Rivian, but the Max and Large batteries have been completely re-engineered and offer ranges of 420 and 330 miles, respectively, based on estimations. They will continue to use 2170 cylindrical cells, and the pack enclosure features a “large high-pressure de-casting” system to simplify manufacturing and reduce mass.
The new Standard Pack will feature lithium-iron-phosphate (LFP) chemistry and provide an EPA-estimated 270-mile range.
140 miles of range can be regained in as little as 20 minutes and are compatible with all major public high-speed charging networks. This includes the Rivian Adventure Network and the Tesla Supercharger Network.
Design and Experience
Rivian honed in on new features with the R1T and R1S and also added two new premium interiors, new exterior paint options, and new darkout trim options.
These are in addition to the new wheel and tire choices, and now vehicles come with a new electronically tinted glass roof, new in-cabin storage, interior lighting themes, new digital interfaces, and new cell shading designs for the different drive modes. It has also improved on the wireless charger.
Surround Sound Audio with Dolby Atmos is available with Rivian Premium Audio.
Refined Electrical Architecture and Compute Platform
The second-gen R1 features new electrical architecture and a new compute platform that was developed in-house by the Rivian hardware and software teams.
“While the exterior of the R1 looks similar, the electrical system is completely redone, providing a significant increase in features as well as a dramatic increase in sensing and compute capability,” Rivian’s SVP of Electrical Hardware, Vidya Rajagopalan, said.
Trimming the ECU count from 17 in the first-gen to just 7 in the second-gen, the “massive simplification” was part of a shift in zonal architecture. Infotainment, autonomy, and vehicle access, as well as battery management, all have their own ECUs. Every other vehicle function is controlled by the remaining three.
Rivian Autonomy Platform
The Rivian Autonomy Platform utilizes “11 internally developed cameras and five radars performing over 250 trillion operations per second, an industry-leading level of compute power.”
The cameras are high-resolution and now include 4K HDR units, which have 360-degree visibility and can see three-times farther than the previous system, as well as 10 seconds ahead at highway speeds.
These are the most camera megapixels of any EV in North America and enable improved dynamic range and clear vision in high-contrast scenarios, like tunnel entrances and exits.
Rivian is also utilizing a cabin-facing camera in the rearview mirror to detect both driver fatigue and distraction when operating in Enhance Highway Assist mode, which will roll out later this year.
The Autonomy Compute Module is backed up by dual NVIDIA DRIVE Orin processors, delivering 10 times more compute performance than the previous system.
Pricing
The new R1S will start at $75,900 and the R1T at $69,900. Dual-Motor configurations can be ordered today and are available immediately. Tri-Max is expected to be launched in the late Summer, while Quad Max will come shortly after.

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u
— TESLARATI (@Teslarati) October 26, 2026
The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
