Back in 2007, Lambo wowed the crowds in Frankfurt with its original Reventon Coupe
, a stealth-fighter inspired, carbon-fiber, all-wheel drive supercar with a 6.5-liter/650-horsepower V12 and the ability to hit 211 mph. This time around, the Audi-owned Italian boutique automaker returned with an open-air version of the car that boasts even more outrageous character. The Roadster is fitted with a 661-horse version of that V12, lifted directly from the Murcielago LP670-4 SV model and backed with Lambo's six-speed E-Gear electronically controlled automated manual transmission. While the Roadster does sacrifice about five mph on the top end, it still can sprint to 62 mph in the same 3.4 ticks and gets an auto-deploying rear spoiler that rises at 80 mph and resets to an even more aggressive angle at 136 mph. According to Lamborghini
, the Reventon's basic structure was so stiff that additional reinforcing on this targa-topped Roadster variant added only 55 pounds to the Coupe's 3,638-pound curb weight. Although exposed carbon fiber remains a prominent visual cue, the Roadster's matte-finish material is a unique Reventon Grey that's slightly lighter than the Coupe's bodywork. Lamborghini plans to hold total production of this de facto road rocket to less than 20 units which will be delivered next month. In case you're curious, each car will carry a pricetag of 1.1 million euros ($1.6 million).
