The Lamborghini Gallardo is the Italian supercar maker Lamborghini's "entry-level" car, sitting beneath the Murciélago. It is also the first car to feature the new Lamborghini V10 engine - only the third engine designed by the firm. 5,000 Gallardos were built in just three years, making it the company's most-produced model to date. The second-place Diablo took a decade to sell 2,903 units.
