It is confusing what the Rivian overall strategy is on these modes on gen2 performance vehicles
I never had bad experiences with Gen 1 - it's just limited by its hardware (poor cameras, inferior radar visibility, slower processing). Gen 2 doesn't slam on brakes for shadows, doesn't run up on traffic and slam on brakes at the last minute, and has full visibility of the cars around it. I never felt that any of those sporadic behaviors made Gen 1 a bad system - just a limitation of its hardware (partly caused by them trying to launch during the pandemic.). Neither is perfect - but no ADAS system is.
This is exactly what kept me from using ACC on our Gen1. Unless I adjusted the gap when approaching slowed/stopped traffic, it created stress for me, any passengers with me, and probably the driver of the vehicle in front of me. ACC on Gen2 behaves rationally and smoothly, even with the smallest gap set.
I know. They won’t do CarPlay but then won’t provide some basic functionality another way. Yeah you can use Siri but it’s annoying and nice to have more integration.
It's how the EPA certification was done. mistakes were made and everything has to default to those settings. You can get AWD in all purpose by turning stability control down but it won't stick. Otherwise you need any mode change except all purpose. If you want AWD permanently, you'll need to rewire the trailer connector to force tow mode.
Yeah I’ve heard the same explanation on the epa certification. But it is interesting then that vehicles that got the software upgrade to performance have some acceleration improvements even in all purpose mode. Which seems to at least partially debunk Rivians own logic on why you have to activate a special mode to get the performance boost.
Rivian opted to use permanent magnet motors in the rear because they are more efficient than induction motors. Because of this, they need to be physically disconnected when not in use. Rivian does this through a clutch system. The clunk is the rear motors being re-engaged, albeit in a rough manner. It was much smoother last fall than it is now.
Gen 1 Quads would drop out of off-road modes for the same reason after some change in '23. The first change meant all you needed to do was get out, check where your vehicle is, get back in, start up, and boom, all-purpose standard. At least until the EPA complains, they can get away with whatever they want.
Pic quality is kinda bad as I was taking it through a filthy windshield.
This is great news! Many of us have been asking for this since 2022 launch. I may just leave my bike rack on all the time now! Thank you Rivian!
Another thing Rivian can do software-wise is to add a “Conserve” mode driven by the front motor only and change the current ”All-Purpose” to include both motors 100% of the time. Good-bye clunk.
I don't think they can change the behavior of the dual motor and maintain the EPA range rating. In my Tri, it does exactly what you are asking for. But the EPA range is sufficiently reduced.
