Audi etron regen on Pikes Peak

did any of you guys see this article? audi claims to be technical first in one-pedal regen type braking. am i missing something? how is audi's system better or different from tesla or jag?

https://www.cnet.com/roadshow/news/a...-braking-test/

I mean, the piece is entertaining and all, but ... this stuff is not new technically, is it?

Yeah, I agree, I don't see any real breakthroughs described in that article either. Perhaps they have some neat technical innovation, but there's not enough technical detail to show anything really superior here.

I think the Jaguar's regeneration is stronger than the Audi's - 0.4g vs 0.3g, if I remember correctly. Audi's 0.3g would be better than Tesla, though. The Audi 'paddles' sound like they could be more cumbersome than Jaguar's pedal controls, but I couldn't say for sure without more info or trying them out myself. Based on what I've heard so far, I expect the Jag's regen to be similar or better than Audi's overall.

Better story about the e-tron quattro:
https://www.autoguide.com/auto-news/...les-range.html

The real story here is this:

Quote:
According to Audi, the e-tron will have two electric motors with a combined output of 265 kW (about 355 hp) and 413 lb-ft of torque. This level performance will be on tap for about 60 seconds, Audi says. While that limitation may seem a bit disappointing to performance-minded buyers, Audi says the vehicle will still be able to “accelerate from a standstill to the electronically limited top speed of 200 km/h (124.3 mph) several times consecutively without output losses.” Additionally, the vehicle can be put into ‘S’ mode, which will call up an extra 35 kW of power and boost torque to 490 lb-ft for roughly eight seconds when the pedal is fully depressed. With ‘S’ mode engaged, the e-tron will hustle from 0-62 mph in “less than six seconds.”
Oh and that it's only 248 mile range under WLTP as oppose to the I-Pace's 298 miles. I'm really glad I didn't wait for the e-tron quattro to trade my A3 e-tron, instead I ordered the I-Pace last July.

It's way too early to evaluate the Audi compared to the i-Pace or Teslas.
  • Comments like "20% less stopping distance" instead of a number. Will it outstop the Audi Q7 Prestige? This I will have to see.
  • 0-60mph in under 6 seconds, but how much under 6?
  • Full power for 8 seconds? That's could affect passing distances in the real world, and hurt 1/4 mi performance. Needs uniform power for at least 15 seconds to cover mountain road uphill passing with passengers. Who wants to have the power fall right as you are ready to finish your pass?
  • All cars with AEB have electro-hydraulic brakes. What makes the Audi special?
  • All cars with ACC that will decel to the point of AEB actuation have no pedal shudder, but you will feel chassis vibration.
  • How big is the Audi inside, seating?
  • And most importantly, what is the pricing? This is a critical factor to know what to compare it to.

The trip down Pike's Peak doesn't say much. It's an average of 6.8% grade. Drops 6,800 feet in 19 miles.
There is a grade near our shop which is 6.0%, and our cars regen at less than 20% of max, 10-12kW.
I assume there are corners that require more regen to lower the car to a safe speed, but 5x normal highway speed 6% downhill rate? I have nothing to compare that to.

Sorry Audi. I have to file that "ride-along" as a 'stupid pet trick'. A SPT is something that is entertaining, but not very useful.
GM's never did a Ride-Along, and I'm not sure Jaguar did either.
GM had the press reporter drive the Bolt around an Autocross course, as did Jaguar.
Then the next step for GM was to put the press behind the wheel 240 miles from their destination. All the cars made it.
Jaguar upped the ante with that full blown abuse test of the i-Pace, dirt roads, city streets, and roadracing, and ace'd all three.

Not trashing the Audi, but trashing the 'press demo'. Audi should have just skipped that stunt. Somebody might take a Bolt or i-Pace down Pike's Peak with zero friction brakes, or recover more kWh's.

Let's wait til Audi's official introduction on September 17. Right now they're releasing information piece meal. But from what I'm reading so far, I'm thoroughly disappointed.

I've seen pricing on the e-tron starting at $99,000.


Non-starter . . .

Fascinating. Now if only I drive down hill 100% of the time, this would be remotely relevant...

I think I originally saw that pricing at autogefuhl's review of the e-tron, but it's also discussed here:

Did you consider the electric Volvo XC40? It looks like it might be nice, but I have not seen a lot of info, and I'm not clear on when it might arrive.

Nope. I need a replacement car to my A3 e-tron January 2019. The I-Pace just ticked off a lot of my check boxes.
