So, 415 Nm of torque (306 ft lbs) at 7,000 RPM is 407 hp. Not a bad number to toss out there when people talk about these EVs being "golf carts"...

Good point! From the TM Model S Features page, torque/RPM chart:So, 415 Nm of torque (306 ft lbs) at 7,000 RPM is 407 hp. Not a bad number to toss out there when people talk about these EVs being "golf carts"...
What speed is 7000 RPM?
For a fixed gear ratio car (like the Model S or Roadster) speed is linear in RPM. We know the top speed is 130MPH at 16K RPM, so it's 130MPH/16K RPM = 8 1/8 MPH per 1K RPM, or about 57 MPH at 7K. This is much nicer than the Roadster.
you're assuming that the limited max speed correlates to the useable max rpm ... i would think that the limited max speed would be closer to 14K rpm or even lower. maybe someone should ask them about this today.
A powertrain engineer said: 1 yes there will be creep, 2 16,000 is maximum rpm, 3 the power starts to drop off in the 50 to 62 mph range but it is not noticeable with road driving. Another said the motor power drops to help with stability control but was unsure if the brakes also contributed. The car will have a dc adapter available which allows 50% charge in 30 minutes. There will be a choice of one or two chargers under the back seats. One will charge about 10kWh and two will double that. This is not needed for the dc fast charge. The power cord or adapter is mechanically locked in place when the car doors are locked to prevent theft.
The car will ignite the revolution that the Roadster heralded.
and insurance rates...I suppose they might want to publish lower/conservative numbers if:
#1: Production variances may have slight differences in power output from car to car.
#2: There could be some conditions (such as extreme heat) where maximum power output is not possible.
