Last year, at what was probably the last IAA in Frankfurt, the spotlight was on the Lamborghini Si\u00e1n, which was given the additional name ‘FKP 37’ in honour of the engineer and manager Ferdinand Karl Pi\u00ebch, who died shortly before. This supercar, limited to 63 units, is the first production vehicle with hybrid technology to be built in Sant’Agata. Behind the passengers, a 6.5-liter V12 petrol engine and a 48-volt electric motor work together to produce a system output of 602 kW\/819 hp and 758 newtonmeters or torque. As there had already been Roadster versions of the previous limited top models such as the Revent\u00f3n, Veneno and Centenario, many experts suspected that the Si\u00e1n would also follow in an open version. Rightly so, as we have known since last night.

While the Coup\u00e9 was limited to 63 units, as mentioned above, the Si\u00e1n Roadster is only available 19 times. If you put these two numbers in the right order, the year of Lamborghini’s foundation is the result, 1963. In terms of performance, the 819 hp of the closed version remains. This means that the Roadster can accelerate from a standstill to 62 mph in 2.9 seconds and will reach a topspeed of more than 217 mph. The 34 hp electric motor is integrated into the gearbox and supports the vehicle during hard acceleration manoeuvres to bridge the shift pauses. In slow driving conditions, for example when parking or reversing, the Si\u00e1n can also be moved purely electrically. Instead of classic lithium-ion batteries, Lamborghini is the first manufacturer to use a supercapacitor, which offers ten times the storage capacity and three times the performance of a battery of the same size. It is located in the bulkhead between the interior and the engine compartment, which ensures a good weight balance. The supercapacitor and electric motor together weigh just 34 kilograms.<\/p>\n\n\n
