rivian ota brings better range and cool winter weather features for r1s and r1t

Over-the-air (OTA) updates have made it relatively easy for automakers to add new vehicle features and improve or fix existing functions. The technology is especially impressive with EVs, where companies can make tweaks that impact major vehicle characteristics like range and performance. With its most recent OTA, Rivian made significant improvements to the R1S and R1T, making them more efficient and friendlier for people living where the air hurts their faces in winter.

Rivian’s release notes state that snow mode softens throttle response and reduces regenerative braking to increase stability and control. Snow mode also changes traction control settings and works with the auto-hold system to improve safety when stopping. The drive mode is intended for on-road use, so drivers heading off the pavement still need to use the Off-Road All-Terrain mode.

Further cold-weather enhancements include a new cabin preconditioning feature. Using the Rivian app version 1.9 or later, the driver can preheat the front and second-row seats, turn on the steering wheel heating, and activate defrost.

More impressively, the update package improved efficiency for the R1S and R1T. The R1T’s range improved from 314 miles to 328, and the R1S improved from 316 to 321. Those figures are for vehicles equipped with the quad-motor drivetrain and large battery pack. The automaker also offers a Max pack battery that delivers up to 400 miles of range.

The update includes other improvements for the infotainment system, safety, and battery longevity. The automaker said the vehicles now offer data and privacy settings that allow owners to limit sharing information such as exact location.

As a two-time EV owner, I've never understood the value of pre-heating a stationary vehicle - all that does is burn kW in the interest of comfort; it certainly won't improve range.
Remote defrost could save time clearing the windshield, but defrost is nearly instantaneous in an EV anyway.

As for Rivian, the MAX battery pack remains vaporware. Also, hopefully they have improved their navigation - reviewers say it's terrible.

  I figured it was to knock the chill off while it was still plugged into the wall. Once the cabin is warm the heated seats may suffice. I don't do it, but I don't live up North either. If I needed to thaw it out every morning I'd rather do that plugged in. People do the same with remote start on ICE cars.

One has to wonder how much EXTRA electricity is required to keep these batteries at optimum temperature in the cold? This further highlights why EV's are promoted with false economies of savings.

  It takes a lot of energy, simply because of the thermal mass of the battery. Despite this, there is an operational savings over ICE, but it's not the EPA rating, and the mfr won't tell you.
  Functionally, I think these conditioning features only warm the battery just before a scheduled charging session - not during the entire drive time.
  I rarely use public charging, but during a recent session in the cold I noticed that my battery temperature rose 30 F in the 11 minutes I was charging at 67 kW. This was a 2.4C charge rate on the small 28 kWh battery in my car. That sip got me 35% for about $1.50.
  With such a dramatic temperature rise, I don't really see a need to pre-condition, but I suppose it could save a few minutes on a larger battery.

  Everything surrounding the promotion of EVs is false. It's a house of cards.

Theflyersfan The two Louisville truck plants are still operating, but not sure for how much longer. I have a couple of friends who work at a manufacturing company in town that makes cooling systems for the trucks built here. And they are on pins and needles wondering if or when they get the call to not go back to work because there are no trucks being made. That's what drives me up the wall with these strikes. The auto workers still get a minimum amount of pay even while striking, but the massive support staff that builds components, staffs temp workers, runs the logistics, etc, ends up with nothing except the bare hope that the state's crippled unemployment system can help them keep afloat. In a city where shipping (UPS central hub and they almost went on strike on August 1) and heavy manufacturing (GE Appliance Park and the Ford plants) keeps tens of thousands of people employed, plus the support companies, any prolonged shutdown is a total disaster for the city as well. UAW members - you're not getting a 38% raise right away. That just doesn't happen. Start a little lower and end this. And then you can fight the good fight against the corner office staff who make millions for being in meetings all day.
Dusterdude The "fire them all" is looking a little less unreasonable the longer the union sticks to the totally ridiculous demands ( or maybe the members should fire theit leadership ! )
