The Model 3 is quicker, stops sooner, tackles the figure-eight faster, has more horsepower and torque, steers quicker, and uses a quarter of the energy than the BMW 330i.

Interesting point!

If you tracked a Bolt, does it drop into that mode?
How would a base Bolt and base Model 3 do competing on a road course for ?10-20 laps? (similar tires to be fair)

(T can 'ludicrously' get power from the pack and motor(s) for a while -- before heat catches up.
And don't they limit your 'Fun Times' using those Go Fast Modes, presumably to keep from degrading the pack and gadknows what else.. ?)
They have run the bolt at Laguna seca and it does go into a limp mode. If I remember correctly the bolt did faster laps than the model S.
Thermal issues really limit electric cars to drag races. They just are not designed to handle max power for long periods of time.

I know on our Rc cars the motor efficiency is a really important factor. Most classes become thermal limited with the motor not being able to shed enough heat. Minor decreases in resistance result in faster laps. Also battery ir is important as it controls voltage sag under big loads. Back in the early day of lipos, say 2005-2006 packs were rated in max burst amps and max continuous amps. Very different ratings. I would guess the ev's have the same issues and might be why the long range tm3 has better performance. Larger battery has better performance.
I also suspect that the $9k price difference between the long range and standard is simply a different pack along with profit to make the numbers work. Especially as the Bolt pack only costs $13k for a full 60kwh. So the 20 kWh difference should only cost about $4-$5k.

How do we know this without independent testing?

I've seen a track test where a Tesla Model S outruns its TMS and starts reducing power.

It was stated a Bolt can do this.

We need professional testing, not weekend warrior track day results!:cool:
There have been enough reports that thermal limiting does happen on the race track with current ev's. It can be overcome, but the current market really doesn't require it. It is far more load than required for normal driving. Even more load than the bolt would see running at max speed for the whole battery pack. As a bolt owner I am not going to take it to the race track. I have other vehicles that are built for that purpose.
When I raced at Laguna seca our qualifying session was 50 min. My only concern was if my 4ah battery would run the ignition for 50 min. It did and I ran the whole qualifying session at race pace. Pretty sure there is no production ev that could do that today. That doesn't mean it won't happen.
