Rivian Rivian - started production

[Sunny]

Can't find any old Rivian thread. But looks like Rivian started production -

First Production Rivian R1T Rolls Off Assembly Line

The wait for the first modern all-electric pickup to enter series production has ended as the Rivian R1T rolls off the production line.

Fun facts - 135 Kwh battery, 315 mile EPA range. 4 motors! 800+ HP, 900 lbft, 3 sec 0-60. $68k. Curb weight - 2680 kg. Not much more than AMG EQS53 - 2655kg. And quicker to 60!

Specs look great, but I would prefer less hp, slower 0-60 and more range, 600hp, 5 sec 0-60 and 400-450 mile range.

I don't know about slower, but you can opt for a bigger battery pack that increases range to 400+ miles.

But this is EPA range and not the idiotic WLTP. The realworld range (with the 135 kWh battery) will be at least as big as that of the EQS with the 107 kWh battery.

And also with EVs less PS does not automatically mean more efficient. During the range test they use maximum 50 or 60 kW power and sometimes four 800 ps motors could be more efficient when powered with 50 kW than two 535 ps motors. Or what I'm trying to say is that reducing power will not necessarily increase efficiency.

I don't remember the exact yea, but early dual motor Model Ss had more range than single motor versions with same battery size cause they tuned one (rear) for acceleration and the front one for cruising.

I love that Rivian went with quad motor setup - should be the gold standard for EVs. No crude diffs, no wasteful torque vectoring via brakes.

Agreed triple or quad motor should be the only way to go for performance BEVs

By the way, the R1T is smaller than it looks. Anyone have dimension or comparisons to standard trucks such as F150?

Seems to also have serious off road ability. Matches/Betters G class -

This company is a joke, they have been seeking an IPO around a 70$B market cap, without producing a fricken car, it’s just another let’s ride the EV hype wave, good for nothing company…. They all try to copy Tesla, and while I’m not a fan of the product itself, Tesla pushed the whole industry like no other. These other Rivian and FaradayFuture like companies, even Lucid to some extent are doing the exact opposite, all marketing and bullshitting, and no car at all…

Although Tesla's engineering is second to none, the business should have died ten times already.

The only reason why Tesla still exists is because the business has billions in support from investors. Rivian has the same which is why it will succeed unlike other EV start ups.

The Model S had an induction motor on the front axle and a PMSRM on the rear. That configuration allow for no losses from the front axle when you dont use it, because the rotor is just a steel cage and it does not induce current while being rotated from the tires ( while the permanent magnetic rotors induce current always when they are driven). So in the range taste you never need the power of the two motors and only the rear one is used, without any efficiency penalties coming from the front motor, or the result is equal to a car with only one motor. But when you need to use more power(no such case in EPA or WLTP tests) the induction motor could be quite unefficient.
Concearning the number of motors, I like more the Tesla's solution with 3 motors but only on the condition that the diff it is coupled to has a true LSD. With front tires a true torque vectoring could be a bit dangerous, because these tires have also to steer. Also when you have two 200 ps motors one per tire, if a tire loses traction you can apply only 200 ps to the other tire, while if you have one 400 ps motor with a LSD, you can have all 400 ps to the wheel with the traction. That's very useful when towing a heavy load.

Can't wait to see videos of people trying to drive a Rivian like a Corvette around corners but end up learning the heard way that it doesn't brake and handle like a sports car.

I don't know why there is no safety directives regulating the acceleration on streer legal vehicles in relation to their weight. The manufacturers should be more responsible for any damages or casualties due to the use of excesive power.

On a related note, I drove an XC60 T5 hybrid two months ago. It is hands down the most dangerous car that I have driven. It has brisk acceleration but even a gentle tap on the brake induce shocking dive. It's as if the body of the car has a body that's a attached to a frame with rubber bands. When braking before corners the car want to do a front somersault!

For the Rivian, AWD and torque vectoring will help disguise weight. However this leads a false sense of security. AWD cars can be easy to drive hard but there's no progression towards the limit. You either in 100% control or the car snaps unpredictably.

Lastly, EVs might accelerate fast as super cars but lack the same braking capabilities. Fun fact, all Porsche cars can brake from 62-0mph in half the time it takes them to go from 0-62mph.

I think people chronically underestimate the advantages of a good EV platform. Here is BEV family crossover acing Moose test, doing better than the quintessential German sports coupe. And more than just the speed, the commentary on how easy the maneuver is with former compared to latter is more telling. It might not set some scorching lap around Nurburgring, but for stuff that actually matter day to day, it is tough to beat a good BEV.

The equivalent ICE crossover looks ridiculous even trying it -

ps. And just like that, the moose test will be now labeled flawed and cast out of GCF and shall not be mentioned henceforth.

The fast lap times will come soon enough.

Yes, but yet, not as fast as the moving goalposts.

I couldn’t agree less. Rivians rollout has been brilliant. Their product is receiving rave reviews. Their management is excellent. The IPO number is reasonable given their order backlog, major investors, etc. This is the first company I’ve seen come out that can reasonably challenge Tesla for EV supremacy.
