Horsepower Distribution of a 2023 Pure AWD...

[Buffalo Bob]

I was curious as to how horsepower and torque was distributed between the two motors of my 2023 Pure AWD, and found the following information on Car & Driver's review of the car.

POWER (SAE NET): 209 hp (front), 342 hp (rear); 480 hp (combined)
TORQUE (SAE NET): 273 lb-ft (front), 413 lb-ft (rear); 686 lb-ft (combined)

I struggled to comprehend how these numbers work together, if they are indeed correct, but such matters are way out of my wheelhouse.

Thought at least some of you might find the data interesting...

With limited knowledge of how to measure the battery capacity and software limitation in relationship to H.P. output to the wheels, I think the best we can hope for is someone to dyno test them, if that's even a thing anymore?

Front and rear numbers are the limits of each motor. Combined figure is likely the battery power limit and current limit.
The car's software distributes power freely within these limits to achieve best handling and acceleration.

Correct. This is also how many hybrid cars work.

I had a conversation with an EV9 owner a few weeks ago and he told me the his AWD disconnects the front motor when his cruise control is engaged. This feature improves his efficiency. Interesting.

Makes sense that those would be front and rear limits. I don't think your statement is about the battery power and current limits is correct, unless you mean that those limits are set by the software, as the 619 HP 2023 Touring has exactly the same weight, motors, battery, wunderbox, etc...

I tried to find the similar data for both the Touring and Grand Touring trim levels, and could not.

It would be interesting to know what each trim level's HP could theoretically be with nothing more than a software upgrade, similar to what some other EV makers have offered as post-sales upgrades.

I’ve been thinking the same. I’m pretty sure my Pure AWD is a software-detuned Touring.

I think that's pretty much indisputable for the 2023 models, of course other than differences in amenities. A look at the two trims with a VIN decoder confirms the degree of similarity.

I imagine that, beyond the hardware differences between them, the Touring is to some extent a software-detuned Grand Touring, but those hardware differences put the Grand Touring's performance well beyond the Touring's capability.

I was under the impression that the Pure AWD uses the same motors that were in the Touring but software limited. Always wondered why the Pure gets lower range than the Touring if the battery packs have the same capacity. Having the front motor disengage on cruise control in traffic to improve efficiency would be neat.

Perhaps incorrectly, I figured the small EPA range difference between the 2023 Pure and Touring trim levels just fell within 'situational' error. Maybe a slightly different temperature on test day, driver weight difference, etc.. Unlike ICE cars, I don't think the higher available horsepower of the Touring would negatively affect the EPA range, as the conservative way they test would leave that added power untapped.

Maybe a significant shift of power to the rear motor at highway speeds at least partially explains why the low speed front motor whine goes away.

Interesting that on the EPA web site, ALL of the information on these two 2023 trim levels is exactly the same except for the total range figure.

Maybe a slight battery degradation difference between the two tested models accounts for the 3.5% range difference.
