Lamborghini Roadster Sian: hybrid song atmospheric V12


The first hybrid Lamborghini got an open version of the Roadster, which will be released edition of 19 copies. Edition coupe Sian was 63 units, and thus together with the “Roadster” it forms a figure of 1963 – the year of Foundation of the company Lamborghini.

Sian hybrid coupe made its debut in September last year on the eve of the Frankfurt motor show and was the answer of the company Lamborghini to contemporary environmental discourse in the automobile industry, require a wholesale electrification for the sake of saving the planet from so-called global warming. Specialists from Sant’agata Bolognese have chosen a relatively easy way of ‘greening’ and turned a middle-aged Aventador coupe in the low-voltage hybrid, that is, applied circuit, typical for bulk and relatively inexpensive cars.

But, of course, not without the original decision: 34-horsepower 48-volt electric motor implanted between the atmospheric V12 (6.5 liters, 785 HP) and a 7-speed “robot” with one clutch, and they generated during braking electrical energy is stored in the located behind the seats of the driver and only passenger of the supercapacitor. Compared to lithium-ion battery of similar capacity supercapacitor is three times lighter (hybrid module weighs just 34 kg), faster accumulates and releases energy, but efficient only at speeds up to 130 km/h, while the “maximum speed” Sian UN Roadster 350 km/h. Maximum total power plant capacity – 819 HP, it manages a simple system of four-wheel drive with inter-axle clutch Haldex. First “hundred” Roadster gaining in 2.9 s, which is 0.1 sec slower than the coupĂ© Sian (probably affects b?larger mass, a value which the manufacturer does not).


Lamborghini doesn’t say what the environmental effect of the hybrid scheme and allows how to reduce your carbon footprint, but the effect for the consumer is obvious – the electric motor in the transmission not only gives short-term extra power and better throttle response, but also performs the function of a torque Converter, that is smooths out the markets at the moments of switching gears, making acceleration and deceleration are more smooth, much easier to maneuver at low speeds.

In General, in terms of skill Sian Roadster is no different from the original coupe, but looks a little more spectacular due to the lack of a roof and more sculpted design of the cover of the engine compartment with the two carbon arcs of security. Active cooling flap in the feed that reacts to the temperature of the exhaust gases, the “Roadster” saved.

The word “Roadster” in this case we take in quotation marks, as outdoor Sian they, in fact, is not a real Roadster based on a traditional layout, a version for Sian without a roof would be suitable prefix Spyder that is used to open versions of the Junior model Huracan. But marketers for some reason insisted on a “Roadster” – leave it to their conscience. The important thing is that the few happy owners of this model will be able to enjoy a clean high-speed singing of the V12 engine, and a hybrid superstructure that does not interfere.

The cost of Lamborghini Roadster Sian is not named, since all scheduled for release 19 copies have been distributed to the best customers of the Italian brand. Needless to envy them, a philosophical question. Only note that in terms of power Sian Roadster by today’s standards isn’t anything outstanding: debuted recently folksy Dodge Challenger SRT Super Stock V8 with the old school compressor has only 1 HP less (ie 818 HP) and this is not to say that looks less cool – it’s just a different, coarser aesthetics and Sian Roadster is designed to win the hearts and wallets of sophisticated aesthetes, but for them today is more interesting, such as De Tomaso P72.
