old thread here, but the specs on my RS AWD is 288HP, 333lbs of torque, I did not clock the 0-60 yet, but it is fast enough for me. Lets say I use to drive a 330HP BMW X5 AWD and a 450HP Cadillac, this car is faster than both of those easily in 0-60. the one pedal driving in High Mode is quite a blast, that is my normal for sure. It has been 3 days with the car and I never touched the brake, not even once.

It's that instant torque that's creating a false sense of speed The X5 weighs 2,000lbs less, at about 340HP, it's clearly faster than our RS Blazer in 0-60, 1/4 mile and every other metric you could think of.

You realize that all EVs are "larger vehicles" just by their nature right? My Leaf weighs more than my Camaro, which seems kind of odd to me. It weighs in just under 4000 lbs. but can still do a decent scoot to 60 in about 6 and a half seconds. EVs will always have an advantage over ICE just based on the fact that their torque curve isn't really a curve, just a straight line. Of course, once an ICE gets into its power band it's going to depend on how much power is on tap at what RPM and if the driver is power breaking. I actually think that the RS will be plenty "quick", especially to new EV drivers that haven't had the experience of instant torque. Hell, my Leaf is plenty quick for what I use it for (daily driver where the Camaro is my "therapy animal"). My goal with the Blazer is more range as that's the performance metric I'm most interested in.




Tuning? Throttle tuning? I think it would seem kind of weird to have the accelerator depressed and other electronics try to bleed out the throttle inputs, especially on an EV. I know that ICE vehicles get tuning to help them with handling extra weight from a stop, or if similar powertrains are used across multiple platforms, but I can't imagine GM bleeding out how efficient their motors run as it would essentially mean they'd be cutting their own range which is the other metric that EVs are measured on. I guess maybe traction control would be one way to shed the power going to the wheels, but just seems counter-intuitive to extracting the most range out of a vehicle.

As for tires, it's not just the accelerating that has killed them for me. I suspect that using regenerative braking on my Leaf is part of the reason that I got less than 14K miles out of my Michelin Energy Savers. They were supposed to be good for 30K miles IIRC. If you are new to the EV scene, just something to keep in mind, tires are going to be expensive on a heavy vehicle with instant torque and aggressive regen braking. Might want to invest in some Goodyear/Michelin stock.

There's a few things i would like to say.

• Regen braking is the motor itself, the momentum energy of the car being recuperated in the motor reversing magnet doing the job. The tire wears out more because of the extra weight and the harder compound that is used for low resistance rolling. The regen braking does indeed brings more wear to non-EV tires.
• Electric motor are driven by electric current, too much current on standstill will just keep the tire spining, the car monitor the slippage of the tire and provides adequate power to the wheels. Therefore, yes, the car limits the power to the pavement; thus, throttling is the correct terms. But its throttling the electric current. As you gain speed, there will be less slippage between the pavement and the tire. THen, more power can be transfer to the motor. All this is happening on millisecond.

I'm speaking with an mechanical automotive engineering degree.

The Michelin Energy Savers that came with my Leaf would like a moment for rebuttal. At about 14K miles they were down to 2/32nds on the tread. I still think that the weight of the EV plus the regen braking just being a constant contribute to the tires. Also, if you begin the regen braking too late, you generally have to squeeze the brakes which could cause some extra wear (granted probably minimal). But mostly, I think it's just the weight of the car.

As for acceleration, I still think the flat torque/power "curve" of an EV can be a little better than the torque/power curve of an ICE. Think of it in terms of the tire and the pavement having to overcome a flat torque/power line versus one that builds as the engine speed builds. In an ICE, you're literally building more TQ and power while the car is still trying to grip during that initial take off. This is actually my real world experience as I've been at a stoplight with a Tesla MY in both my Camaro and my Leaf. I've pulled more than a few times on a Tesla in my Leaf, where in my Camaro, out of the hole I'm already 1 car length behind after only about 30 feet.

I'd love to put more aggressive rubber on my Leaf just as an experiment, but more aggressive rubber tends to cost more and the tread wear is usually under 20K miles. Considering my Leaf is my daily driver, I don't think I will be spending extra for that little experiment.

0-60mph in the AWD Lyriq are broadly reported to be ~4.6 to 4.9. Cadillac programming rolls out power a little slow at first to provide a smooth take-off. I would expect the SS trim Blazer to be in this range... with the potential to be very marginally faster if they choose to dump all the available power at take-off.
