Don't expect it to look anything like the Sian.
One of the main stars of the 2019 Frankfurt Auto Show was the Lamborghini Sian. Limited to just 63 units costing $3.6 million each, the Sian's striking design was clearly influenced by the Terzo Millennio concept that debuted in 2017. Traditionally, Lamborghini's concepts and limited-edition models preview the design of future models, so many have assumed the Sian would inspire the design of the next-generation Aventador.
This won't be the case, however, according to Lamborghini design boss Mitja Borkert. "That's a clear no," he said when asked by Autocar whether the Sian will influence the styling of any future Lamborghini model in the 2020s. "There was a certain closeness of design between the Reventon and the Aventador. This is exactly what I don't want to have," Borkert explained. "There will not be this language in the new Aventador."
Instead, the Sian was designed to stand out on its own. As well as the Terzo Millennio concept, the design is inspired by high-performance motorcycles and racecars that competed in endurance racing events during the 1960s and 1970s.
Borkert also revealed that he didn't want the Sian to continue the wild design direction established by other limited-edition Lamborghini models like the Veneno. "After Veneno, after all these cars, I wanted to have integrated aerodynamics," he said. "I didn't want another wing car with a spoiler sticking out. I wanted to have something where aerodynamic efficiency and design meet in something completely new."
The Sian's design isn't the only element that won't carry over to the next Aventador. It was also recently confirmed that Lamborghini's new flagship supercar won't utilize the Sian's revolutionary hybrid powertrain that features a supercapacitor, which is three times more powerful than a battery of the same weight and delivers engine torque directly to the rear wheels.
Why? Because Lamborghini designed it to improve performance rather than efficiency, which won't be very practical for a series-production car. Instead, it will likely adopt a plug-in hybrid with a lithium-ion battery. And while there were concerns Lamborghini would be forced to use a V8 to meet stricter emissions regulations, it will retain Lamborghini's signature V12.
