Lamborghini has a history of few-off models, limited run special supercars based on other cars. Typically, these borrow underpinnings from the Raging Bull's V12 range-topper at the time, and inevitably, they end up losing their roof at some point. Think Veneno, Centenario, Sian, and you get the picture. Well as of today, there's a new roofless Raging Bull in town, and it's packing over 1,000 horsepower.Meet the Fenomeno Roadster, officially the most powerful open-top Lamborghini ever made. V12 Power, Hybrid Assistance, No Limits Lamborghini Based on the limited run Fenomeno, launched at last year's Monterey Car Week, the Fenomeno Roadster follows a similar styling approach, but lops the roof off and trims the side windows for maximum theatrical effect. And what's at its heart is reason to celebrate, as it leverages Lambrghini's V12 prowess in 6.5-liter form with the Revuelto's triple-motor plug-in hybrid system to deliver 1,065 horsepower, of which 823 come from the V12 alone.All-wheel drive and an eight-speed DCT automatic enable those thousand-plus ponies to catapult the Fenomeno Roadster from standstill to 62 mph in 2.4 seconds, to 124 mph in 6.8 seconds, and eventually reach a top speed somewhere north of 211 mph. That's one fast way to blow your toupee off.Lamborghini Importantly, this is Lamborghini's first open-top car powered by the new plug-in hybrid powertrain, beating both the Revuelto Roadster and forthcoming Temerario Spider to market. Revised Styling And Aero Mean No Compromises Vs The Coupe Lamborghini Compared to the coupe, the Fenomeno Roadster has a revised aerodynamics package that means no downforce compromise results from the lack of a roof. The most noticeable of these changes is a spoiler on the trailing edge of the windshield (with Fenomeno Roadster embossing) that directs air over the cabin and into the engine bay, which itself has a revised top cover to maximize cooling. This is despite the Roadster lacking the coupe's stylish roof scoop.Even the carbon fiber rollover hoops were developed specifically to minimize aerodynamic interference and wind noise, with a low-profile design that avoids wind buffeting and doesn't compromise performance.Lamborghini But perhaps one of the coolest design details is the side windows. They feature a sloping design that manages airflow, looks striking, and helps lower the visual height of the car overall. Insanely Few Built, With A Price Tag You Don't Want To Know About Naturally, if you order a Fenomeno Roadster, you can specify it in whatever color/s you want. We explored just some of the possibilities with the Fenomeno Coupe last year, and the same is true here.Lamborghini However, that hasn't stopped Lamborghini from revealing it in a show-stopping spec, dressed in Blu Cepheus paintwork on the upper half of the body, with the lower elements treated to Rosso Mars accent coloring. Lamborghini says the two-tone palette is a tribute to the flag of Bologna, while the blue hue honors the first ever Lamborghini roadster available, the Miura.Unlike the coupe, of which 29 will be sold, only 15 Fenomeno Roadsters will see the light of day. That makes it one of the rarest Lambos ever made. As for how much they'll cost, such information would only be shared with customers invited to buy one, but bespoke pieces like this don't sport price tags us mere mortals can afford. Some sources report a $7 million price tag, and you can be sure that with such limited numbers, that value will only increase with time.Lamborghini Fenomeno Roadster blue studio exterior (1)
