Lamborghini has already sold the 20 cars they plan to make at $1.4 million a piece. Lamborghini Reventon

With the six-figure price tag, it is the most expensive car that it has ever built. 

True to its tradition of cultivating an aggressive image, Lamborghini named the car after a bull that killed matador Felix Guzman in 1943.

Although it is based on its Murcielago LP640 model, Lamborghini's engineers took inspiration from a fighter jet and reworked the composite carbon fiber body to accentuate the sleekness and angular edges usually associated with its cars.

The engine is the same as the LP640: a 12-cylinder rocket that can propel the car from zero to 100 km/h in 3.4 seconds.

By comparison, the coupe version of the LP640 costs a relatively more modest 219,600 euros.

Lamborghini, which is run by Volkswagen's (VOWG.DE) Audi division, will start making the Reventon in January and deliver them in October.

The car, which came in an opaque grey at the autoshow, has a three-year warranty.
