The 2023.38 update makes no exception, bringing the much-appreciated Halloween theme alongside new features, improvements, and bug fixes. Most importantly, Rivian overhauled the Drive Mode app, which now has a new user interface, giving "driver-focused control and dynamic feedback to improve situational awareness while driving," as revealed in the release notes.
The redesign brings various controls for drive modes together under a single tab on the left side of the screen. Drivers can select between Drive Modes and Trailers modes. The Drive Modes tab is divided into On-Road and Off-Road for Quad-Motor vehicles. In the Drive Modes tab (for either On-Road or Off-Road in case you own a Quad-Motor R1S or R1T), you can adjust ride height, regenerative brake level, stability control, and suspension setting, which Rivian calls "Ride Feel."
The redesigned Drive Mode app lets you choose the best drive mode while towing based on the environment, driver behavior, and current road conditions. You'll find three profiles in the Trailers tab, each tracking the trailer's range impact, estimated weight, and trip data. It can also remember the Trailer Brake Gain for each trailer.
The best feature is how Rivian improves range estimation while towing. When you connect a trailer, the vehicle continuously learns and stores the efficiency during the trip. It also provides feedback to the driver about the range estimate on the instrument cluster and the range on arrival estimate in navigation. The same range estimation improvements are available within each drive mode, providing more personalized predictions for range on arrival.
A new addition that will be much appreciated by the geeks out there is the Gauge View. This displays data visualizations of the vehicle on the right side of the screen, allowing you to discover more about how your vehicle works. You can use it to see real-time data from the vehicle, such as steering direction, direction of travel, pitch, roll, tire pressure, elevation, and motor and battery temperatures. It also displays trip data, including distance, speed, duration, efficiency, and total energy used.
As usual, Rivian improves existing functions and squashes bugs with every update. This time, it increased the accuracy of charging data and fixed several annoying bugs, including the ones that caused the Media app to crash or the climate panel to appear black. Rivian also promises a reduced active grille shutter noise from the front of the vehicle when the vehicle wakes from sleep.
