Rivian Dynamic Glass Roof – How It Works and Heat Rejection Data

Rivian Wave

Rivian offers a new dynamic roof option for its second-generation R1S and R1T vehicles. It’s a fantastic option for those who want a little extra privacy or are looking to add a little wow factor to their vehicles.

The Dynamic Glass Roof delivers the ultimate flexibility, allowing you to switch seamlessly between privacy mode and panoramic views of the world above your Rivian — all at the touch of a button.

Price

The Dynamic Glass Roof is an option for both the R1S and the R1T and costs the same on both vehicles. In the United States, it is $1,500 USD, while in Canada it goes for $2,200 CAD. In turn, you receive an electro-chromatic glass roof which can change between tinted and clear at the press of a button. In the future, Rivian can even switch it automatically based on whether the vehicle is locked, the outside temperature, or the time of day.

Electro-Chromatic Glass

The electro-chromatic glass takes about 10 seconds to dim, and 5 seconds to brighten up. The shading is lighter on the inside than on the outside. When you look from above, with the roof dimmed, it is almost completely black, with little to no light leakage.

When the roof is brightened up, it is fairly transparent, but slightly less so than a regular glass roof. It’s comparable to a roof with a very light tint when in transparent mode.

How It Works

If you’re curious about how it works, the glass roof has an electro-chromic film sandwiched between glass layers. This film is best used in flat applications, and when it is energized, the particles in the film change direction, allowing the transparency of the glass to change alongside it. It’s a very cool application of physics, and Rivian has done an excellent job integrating it into their vehicles.

Heat Rejection

If you were hoping to pick up the roof for its heat rejection properties, you’ll find this data helpful. While the dynamic glass roof does offer some heat rejection when in privacy mode, it’s minimal. Most of the light and heat that enters a Rivian instead comes through the windshield and the driver and front passenger windows – which are not tinted heavily due to laws around North America.

For jurisdictions where tinting the windshield and front windows is legal, and you’re looking to keep your vehicle considerably cooler, you’re better off tinting those two versus picking up Rivian’s Dynamic Glass Roof.

The Dynamic Glass Roof, when shaded, lets in about 1/3^rd of the light as regular glass, but that’s insignificant compared to the amount the windshield and front windows let in. This table, summarized by @Hook_K, provides additional details.

While the Dynamic Glass Roof does indeed provide slight benefits over the standard panoramic roof for heat rejection, it's not a whole lot when you compare it to the heat that comes in through the windshield or front windows.

We’d consider the glass roof an excellent option to keep a bit more of the sun out of your passenger’s eyes and provide you with a bit of privacy if you drive in a city regularly, where there are many places to see inside from above. We’d also recommend it if you love seeing that electro-chromatic glass change from dim to transparent, which is a cool experience.

While Rivian’s dynamic glass roof is a great option, it should be looked at more as a privacy-focused, fun feature rather than a way to keep heat out of your vehicle.

I love this @Rivian refresh feature for Camping in your car! 👏 pic.twitter.com/3MKMe1MulN

Rivian Battery Options: Range, Cost and Battery Pack Sizes (kWh)

Rivian Wave

Rivian offers a variety of battery packs and motors to give customers the range they need at the lowest price point possible. Let's take a look at the various battery sizes Rivian offers, their costs, and the range you’ll get with each package.

The battery options differ on Rivian’s Gen 1 and Gen 2 vehicles (model year 2025+), so we’ll break it down by vehicle generation. One thing to note is that even though Gen 2 has smaller battery sizes in general, the vehicles are far more efficient than the first generation, so you’ll be able to travel further on the same battery size.

Rivian divides its models by the number of motors and battery pack size. The motor options are Dual, Tri, and Quad, while the battery options are Standard, Large, and Max. So, when selecting a model, you’ll see names such as Dual Standard (two motors and the Standard battery) and Dual Large or Tri Max (three motors and the Max battery).

Here are your battery options for the current generation of vehicles (R1S and R1T) and their range and cost.

Gen 2 Battery Options

You’ll note that the upcoming Quad Motor Ascend vehicles aren’t listed here just yet. Rivian hasn’t unveiled the details of the Quad Motor battery packs and pricing yet, but we’ll update the table above once that information arrives.

The Max Tri-motor models include the same battery pack as the Dual Max models, but their range is reduced due to the additional weight of the extra motor and the vehicle's performance tuning. The Tri-motor vehicles also include a variety of standard options, such as the Dynamic Glass Roof, Premium Audio, the Ascend interior, and others, which drives the price up to the $30,000 premium over the Dual motor variant.

Of note, the only official EPA range estimates are for the R1T’s Standard pack and the R1S’ Standard and Max packs.

Gen 1 Battery Options

Rivian offered more options in its battery lineup in Gen 1, and the range of its lowest-level offering was a bit bigger – 258 miles in Gen 2 compared to 270 miles in Gen 1. That difference is mostly due to the smaller pack size – 105kWh in the Standard Gen 1 vehicles, while only 92.5 kWh in the Gen 2 vehicles.

The battery ranges above are all EPA estimates.

New Details About Rivian's R2/R3 Steering Wheel: Dynamic Clicks & Haptic Feedback

Rivian

Rivian’s upcoming vehicles, including the R2 and R3X prototypes, will include a next-generation steering wheel that offers an innovative approach to driver control and feedback. We recently had a chance to chat with Marty L., UI/UX Director at Rivian, who shared exciting details about the new features and functionality of this wheel.

Three Axes of Freedom

The new steering wheel design looks great, with large, mostly exposed scroll wheels at either side of the steering wheel. However, the most interesting part of the wheel is the functionality it introduces. As expected, the steering wheel will have three axes of freedom, similar to the steering wheels in the current R1S/R1T models, but instead of requiring a separate button to navigate left and right, you’ll be able to tilt the scroll wheel left/right.

• Tilt Left/Right: The ability to navigate left and right by tilting the scroll wheel

• Push In: A push or press feature that can be used to confirm selections or switch modes.

• Scroll Up/Down: Scroll up and down with dynamic haptic feedback

These scroll wheels are the cornerstone of changing the most used settings in the vehicle. However, Rivian plans to use them for more than just basic features. You’ll be able to adjust a variety of settings directly from the scroll wheels.

Dynamic Haptic Feedback

The biggest innovation with Rivian’s new steering wheel will be the ability for the wheel to provide dynamic haptic feedback as you’re scrolling. While most scroll wheels have a basic click sensation, Rivian’s will have adaptable feedback that changes depending on the function you’re adjusting:

• Volume Control: When adjusting the vehicle’s volume, the haptic feedback (the “clicks”) will be more spaced out, with distinct, widely separated clicks corresponding to each volume level (e.g., 1 through 10).

• ADAS Speed Adjustment: For adjusting speed settings, you’ll feel more closely spaced clicks that offer more precise control, giving a tactile sense of small incremental changes.

This feedback ensures drivers get a clear, physical confirmation of each adjustment, making it easier to make changes without taking their eyes off the road.

Resistance for Added Control

The new steering wheel is beyond just clicks, Rivian’s scroll wheels will have varying levels of resistance. Marty explained that users will feel a slight resistance when they scroll up or down to change settings. For example, as you’re scrolling up to the next volume level or speed increment, the wheel will offer a subtle resistance before snapping into the next position. This makes the interaction feel natural and intuitive—almost like turning a dial that clicks into place.

Which Models Will Feature This Steering Wheel?

The steering wheel is currently featured in Rivian’s R2 and R3X prototypes, which have been showcased at various events. This innovative wheel will be rolled out to all R2 and R3 models. However, when asked whether the new wheel would make its way to the current R1S and R1T models, he simply responded with a “stay tuned,” hinting that Rivian may have plans to introduce it to its current lineup in the future.

This new steering wheel design is a testament to Rivian’s focus on technology, software, and innovation to produce some of the best EVs. As Rivian continues to redefine what’s possible in vehicle interiors, as they did with Dolby Atmos support, this new steering wheel will likely set the standard for user experience in future designs.
