If this document
is to be believed, the LEAF's motor makes ts max torque of 206 ft-lbs from 0-2730 rpm and max power of 107 bhp from 2730-9800 rpm. That means the motor puts out max torque between 0 and approximately 24 mph (assuming top speed of 94 mph and max engine RPM of 10,390).
IMHO, that document shows the raw specs of the motor before
Nissan applies their ECU, BMS, and "drive by wire" throttle controls to the motor's output. There is no way that they would allow the engine to apply full power instantly to the wheels from a standing start--that would be detrimental to the battery pack as well as the drivetrain, and the tires do not have sufficient grip to apply it to the ground anyway. I concur with the others who believe the Leaf's software moderates and "ramps up" a full power application much slower than the motor's full capability.
I still say that the LEAF feels quick off the line because it is quick off the line. I went looking for dyno graphs, but could not find any that show readings below 2000 or 2500 rpm, but many "performance cars" shows around the same torque at 2000+ rpm:
Yes, it is true that ICE engines do not develop max torque at low RPMs. This does NOT mean that they cannot launch quickly off the line. The clutch and gearing and driver skill can be combined to make sure that the car is never out of the meaty part of the powerband, even from a dead stop. The most important aspect in accelerating a vehicle is grip
, and the Leaf is sorely lacking in this part of the equation, regardless of how much torque it may have available. The tires are the single most important factor in acceleration performance (and braking and cornering as well). If the coefficient of friction of the tire contact patch is not sufficient to transfer the power to the ground, it doesn't matter how much power is applied. With the wider, softer compound tires that are standard equipment on a modern sports car, and a skilled driver (or modern launch control software), any of the performance vehicles you cite will absolutely smoke
a Leaf off the line, no matter how "quick" it may feel. The stopwatch doesn't lie.
Despite the anemic 175 ft-lbs @ 2250rpm, a new GT3 RS (there is no 911 GT4 yet, BTW) will do 0-60mph in 3.5 seconds (without launch control). There is no way the Leaf could stay with it, even to 20-30 mph.
