First para. of Tesla's blog entry of today with the announcement; emphasis added:
The Model S P100D with Ludicrous mode is the third fastest accelerating production car ever produced, with a 0-60 mph time of 2.5* seconds. However, both the LaFerrari and the Porsche 918 Spyder were limited run, million dollar vehicles and cannot be bought new. While those cars are small two seaters with very little luggage space, the pure electric, all-wheel drive Model S P100D has four doors, seats up to 5 adults plus 2 children and has exceptional cargo capacity.
