Back in 2009, Lamborghini unveiled the Gallardo LP 550-2 Valentino Balboni - a 550 HP special edition limited to only 250 units. This model was only offered in a coupe version, but at the 2011 Los Angeles Auto Show, Lamborghini has brought out a Spyder version to offer a "stunning level of open-air driving fun that can come only from a super sports car with a folding roof and an unbelievably agile and spontaneous handling." The new roadster model has dropped the "Valentino Balboni" name and is simply called the "Gallardo LP550-2 Spyder.""With the Gallardo LP 550-2 Spyder, we are expanding the Lamborghini lineup with a purist model that adds yet another dimension of driving fun. This will appeal in particular to a very special group of customers that enjoy a spirited driving style and also like to experience the sheer pleasure of open-air driving," says Stephan Winkelmann, President and CEO of Automobili Lamborghini. "This special model with rear-wheel drive is a logical expansion of our lineup of spyder models with all-wheel drive."Just like the coupe model, the Gallardo LP550-2 Spyder uses a 5.2-liter V10 engine that delivers a total of 542 hp and 398 lb-ft of torque. With a total weight of 3,351 lbs, the roadster will accelerate from 0 to 60 mph in 4.2 seconds on its way up to a top speed of 198 mph.
