Speaking of which, the ‘25 QuadMax will lay down the same straight-line numbers as a ‘24 C8 ZO6! Freakin’ amazing
Just use headers! Haha
Add me to this group, at least for track use. I'm not sure my quad will get in the 10's, but it could be low 11's.
Some valid points, but why did Rivian raise the limiter on the G2s? As for point "D", I think that is done mostly because at top speed, your range would be pretty atrocious. To put this in context, at the dragstrip with my Model S plaid, I'd use 2% of my battery for each pass. I'd usually trap in the 150's. If I made one wide open pass until I hit top speed limiter of 203-204, I'll use about 5%.
I posted a detailed analysis/opinion regarding the speed limitation a year or so ago. To summarize, I looked at documented specs for Bosch EV motors, Rivian's gear ratio, tire diameter, etc. and the math worked out almost perfectly to 112 mph top speed without exceeding the Bosch motor max RPM specs. I think it is a motor safety/warranty decision by Rivian and/or Bosch to limit the speed in Gen 1, not a "You don't need to go that fast" nanny thing.
I've certainly hit 80 or so in my former Corvette, but that was very rare where topping out at 70 was more common. Powerful cars are fun for autoX, but still more fun if you can actually pull greater than 1G, which big/heavy vehicles won't, though tires are certainly a limiting factor for Rivians right now. I hit 1.4G in my Alfa. Concerns about other equipment breaking is legit. Most organizations also have limits on center-of-gravity and track width vs vehicle height.
Goes both ways. Seen too many crazy attempts at street cars trying to be off-road or dune trucks.
Are you forgetting, still, that the R1s are not small passenger cars, weigh 7k+ lbs and have much higher center if mass? How much did your Tesla weigh? There is also the issue of the tires’ ability to stay seated on the wheels—under dynamic load/stress of 7k+ lbs at speeds greater than 110 mph. Why are these two figures significant? See Newton’s second law of physics. And none of the popular non-factory tires are rated higher than 115-120 mph.
You answered your own question. Those wanting ultimate on-pavement performance don’t care about tire longevity or efficiency. Engineering is a game of compromise. If you want more of something, out of same machine, you have to give up something else to achieve it. It’s the same with high performance sports cars.
It's just like putting a wing or open exhaust on a street car - the owner thinks it looks/goes/handles better based on the mod and their "seat dyno", but it really is essentially all show, no go.
Actually, it has either H or V rating. I cannot recall which but it's been discussed and I thought it would be higher rating but someone on this forum provided a clear image of the tire with the speed rating on it. It's a special tire made for Rivian. Also Michelin changed the naming convention to Pilot Sport Super 5 (PS S5).Just in case folks wonder about tire capabilities on the G2 Quad/Max, Rivian is supposed to put these wheels on 22-inch Michelin Pilot Sport 5s, with a staggered position of 275mm width in the front and 305mm in the rear. These will carry speed rating in the W and Y class above the 130mph top ceiling Rivian is planning for the speed cap.
Impressive!
