Lamborghini has unveiled the Lamborghini Estoque, a new four-door concept car. Lamborghini Estoque is designed for everyday use with seating for four adults and is expected to sell for $200,000. The 500 h.p. sedan is expected to hit a top speed of about 180 m.p.h. "We looked into the entire market and we saw what was missing was a limousine which is at the same time elegant but very sporty," Lamborghini CEO Stephan Winkelmann tells the IHT. Its release date will depend on "the reaction and on the developments in the market," he says.
