but there is four tires!
and 4/4ths of a car

At 2.6-sh second mark your car accelerates with more than 9.8m/s^2 to get to 60. But even lower accelerations will glue you to the seat because gravity acceleration affects every part of your body. Where as the car grabs you by the butt and yanks you forward. So - I think he has probably some vague idea of Newtonian physics but just didn't manage to produce coherent sentence.
How is more than one g accelleration possible? There is one g making the friction between the tyre and the road.
At what battery percentage? Let alone, why? I want range, range, and more range. I could not give a damn about how fast I get to the next stop light or supercharger. Brag when you get 500 miles a charge, even fifty miles more range is more impressive than a tenth of a second off your acceleration "with a full charge"
> I want range, range, and more range. I could not give a damn about how fast I get to the next stop light or supercharger. You're not the target audience for their top-of-the-line P100D. It's aimed at people who would otherwise buy Bugatti Veyrons, Ferraris, etc., and range probably doesn't even come up in their decision making process. The Veyron has a range of 50 miles at top speed, for example.
The people buying Veyrons are doing it for status. They're not going to replace their >$2 million car with one <$2 hundred thousands.

That top speed being 250mph. Who drives 50 miles at 250mph? And where do they do it?
And, more importantly, they can refill in the blink of an eye and travel 50 more.
Is Tesla so fast compared to the price because is an electric car or this is totally unrelated and was just designed to have such an acceleration, without help from the fact it's an electric car? Thanks. EDIT: Thank you for the replies!
To my knowledge the essence of an electric engine is that is has max traction almost independent of the rpm. Where a petrol engine has an optimal rpm (4000 for instance) where it provides most power, the electric car does not. Consequence is that a petrol car needs a gearbox to keep the engine around this optimal RPM (and thus most power) while the electric engine does not need one - it accelerates and keeps on accel…

1. No cold starting. The engine is on as soon as you push power in.
2. Equal torque at all speeds
3. The lack of a need for a transmission. All "gears" can be controlled by how much power you're feeding

The reason why an EV would outperform most motors is mutli-fold 1. No cold starting. The engine is on as soon as you push power in. 2. Equal torque at all speeds 3. The lack of a need for a transmission. All "gears" can be controlled by how much power you're feeding The EV is more like a solid state transistor verses a relay. They do similar things, they're good for different applications, but the transistor has some…

Cars can do more than 1G even without downforce. Sports car street tires commonly ~1.2g, race tires commonly ~1.5g+ High school friction is wrong. Source: various of my cars (in the past, I just have lame hybrids now) and a g meter
No, it's at least mostly correct. High school friction says
F = mu * W
If it's failed you, it's failed in failing to mention that the tire-road interface can have a coefficient of friction greater than one, and in failing to mention that the normal force can be increased with aerodynamic downforce.

It's not equal torque at all rpm.
Also if you can get someone who has a lot of experience with motor control they can get you going pretty quickly. I'm assuming what's in the Tesla is a brush-less DC motor and there are a few things you can do (especially since you're on some serious batteries in the Tesla) to push some serious torque at the startup curve. You're probably only running a modulated power start for a few seconds. After the first few seconds you're shoving the full amperage into the motor.
