Detroit - Tesla says a new version of its Model S electric car is the quickest production car in the world.
The company says its Model S P100D sedan can reach 100km/h in 2.5 seconds.
The Ferrari LaFerrari and the Porsche 918 Spyder, powered by petrol engines, though faster, were million-dollar specialty cars that can no longer be bought new, said Tesla CEO Elon Musk.

The new P100D has a new 100 kilowatt-hour battery pack that extends the car's range to about 506km. The top range of the previous Model S was 473km. The new battery is also available on the Model X SUV.
Battery tweaks
Musk says the battery cell chemistry is the same, but Tesla had to reconfigure the battery pack to store more energy in the same space and handle increased cooling requirements.
New customers can pay $10 000 for the larger battery pack. Existing owners must pay $20 000 because their existing batteries must be recycled.
The Model S P100D starts at $134 500, while the Model X P100D starts at $135 500. The SUV will be able to go from zero to 100km/h in 2.9sec.
