<snip>
But a key difference between the vehicles [Porsche, Tesla S] is where that power comes from. Electric motors are more responsive than gas ones, and while the Tesla runs full-time on electricity, only 95 horsepower out of a total of 416 horsepower comes from the electric motor in the Porsche (the rest comes from the gasoline engine). As Eric Huffman, a Porsche Sport Driving school instructor, told me, The cars have the same power. Its just Tesla has all their power in an electric motor, which is instant torque.
That instant torque, which you notice most strongly in the first second or two of acceleration, accounts for the fact that the Model S can reach 60 in 4.2 seconds, compared to 5.2 seconds for the Porsche, according to the two companies. The Porsche has the edge in terms of top speed (167 mph compared to 130 mph).
The advantage of a gasoline motor is that gasoline stores far more energy than batteries by weight or volume. As a result, while a Tesla only goes about 265 miles on a charge, the Porsche can go around 600 miles on a charge and a tank of gas.
