Lamborghini says the Veneno can reach speeds of 220 miles per hour (355 kilometers per hour) and accelerates from 0-60 mph in 2.8 seconds.
The body is carbon-fibre to keep the car as light as possible and allow for that quick acceleration.
The shape is angular and muscular, with cut-outs sprinkled throughout and a back fin that fades into the roof.
The rear looks like the bottom of a rocket ship, and the car nearly kisses the ground it sits so low.
Who buys a 3 million ($3.9 million) car? Not you. Lamborghini's run of the new Veneno is sold out - though it only made three.
The latest in its tradition of bespoke cars, the Veneno is the fastest, most powerful Lamborghini ever built.
At the Geneva Motor Show, where it was revealed, Lamborghini CEO Stephan Winkelmann made sure to rev the engine as he drove the car out on stage.

Rest assured, the Veneno, which is named for an infamous fighting bull, sounds like a Lamborghini.
Powering the Veneno is a 12-cylinder engine and a 7-speed transmission with five different driving modes.
Scissor doors open up to reveal an interior also clad in carbon-fiber. The feel is suede-like throughout, but the dashboard has a fairly standard look. You don't feel as if you're about to take off.
Lamborghini is billing the Veneno as a race car that just happens to be street legal - but how closely they've hewn to racing technology is unclear.
