Lamborghini Estoque; Paris sedan concept suggests a daily driver.(NEWS)

Iconic sports-car maker Lamborghini could double its sales within four years if it builds its low, ultra-long, super-aggressive Estoque sports sedan concept car.

Powered by a retuned 500-hp Gallardo V10, the Estoque combines supercar power, all-wheel drive and a lightweight chassis in a four-seater that could be the first Lamborghini in history designed for daily use, and the first to have a range of environmentally friendly engines.

"With our existing cars, there is day-by-day usability, but they are not used every day. Most of them are used for less than 5,000 kilometers a year, said Lamborghini president Stephan Winkelmann.

"This car is something different. It's for everyday use.

With its all-aluminum, 5.3-liter V10 sitting just behind the front axle, the Estoque is the first four-door Lamborghini since the 1987 Portofino concept car.

Winkelmann says Estoque is an operational prototype, not just a concept car, and could give Lamborghini between 2,000 and 3,000 sales a year if it goes into production in 2012. In 2007, the company sold 2,405 cars.
