Porsche 918 Spyder is 0-60 in 2.3s. Elon has a ways to go still.
On the other hand, an electric motor can easily produce its maximum torque at stall.
An electric car, with adequately sized motors, controllers, and batteries (or other power sources) should be able to drive the tires to the traction limit from a standing start to the speed where the available power will no longer sustain that level of acceleration - well over 60 MPH. This means the acceleration is limited solely by the coefficient of friction of the tire/road contact surface - a critical parameter that can be tightly tracked, during acceleration, by drive electronics akin to non-skid brake controllers.
So an electric car should be able to get the best possible standing-start rating out of any given tire technology - and be literally unbeatable in such a contest.
IMHO the only reason (pre-Tesla) electric cars had a reputation for being underpowered creampuffs rather than unbeatable sprint sports cars, is that the automobile manufacturers thought the purchasers would all be eco-freaks, more interested in mileage and ideology than performance, and designed lower-manufacturing-cost, underpowered, cars for this market.
