I posted this in another thread, but I apologize in advance for the repost. It concerns this topic and explains why EV tend to perform better than ICE cars of the same power to weight:
Automakers report ICE power as peak HP and peak TQ. EV makers are basically reporting average horsepower because the curve is "flat". A car accelerates over a time interval based on the average HP, or "area under the curve". Here's what a common ICE engine power curve looks like:

Note that if operational rpm range is 4000-6500 rpm during max acceleration, your average is roughly 100kW but rated peak is 110kW.
Now an electric PMAC car:

Notice how during the operational acceleration RPM the HP is constant.
If there is a gear change in the ICE during the acceleration, there is a brief negative HP output that also comes into play. An EV at a given power to weight ratio will normally out accelerate an ICE with the same power to weight. Here's a classic example of EV power vs ICE power in cars with similar performance:
Volts run in pure EV mode during 0-60 mph testing. They are rated at 149 HP (cough) and weighs 3523lb, assume 150lb driver, 3673lb or 24.7 lb/hp. C&D says 7.5 seconds, 0-60 mph.
The Toyota 86 Automatic (Subaru BRZ) is pure ICE with a 200 HP rating. With driver it weighs 2961lb, so it has a 14.8 lb/hp ratio.
So the 200HP, (and 560lb lighter) Toyota creams it, right? Nope. 7.7s 0-60 mph due to the ICE HP curve and automatic shifting time.
Must be traction. Once moving, the ICE Toyota will kill it, right? Nope, both 'automatics' yield the same 5.1s 50-70 mph high speed passing time. The Toyota is quicker in the 1/4 mi by 0.1 seconds though.
This holds true for most EVs, at least up to 80 mph. They punch well outside their weight class.
