A roadster version for the Sian will turn up the exclusivity to eleven for the hybrid hypercar

LISTEN 02:29

Lamborghini loves to churn out as many derivatives out of its exotic-looking supercars and in a move we honestly didn’t see coming, the Sian FKP37 will return to the limelight as a roadster.

A recent report talks about a Sian Roadster that Lamborghini is currently working on, but other details are pretty much nonexistent.

With roof or without roof, that is the question

According to The Supercar Blog (quoting unnamed sources), Lamborghini is brewing a roadster ethos for the Sian FKP37 electric hypercar. That’s all we know so far, and Sant’Agata Bolognese will likely remain tight-lipped until an official reveal takes place.

That said, we’re being left with a lot of blank space to fill with speculation on what a roadsterized Sian might look like.

The big dilemma here is whether it will flaunt a removable roof - like the Aventador Roadster, for example - or no roof at all, a la Veneno Roadster. Given that the Sian is actually based on the Aventador, we feel the first avenue is the most probable, but we won’t hold our breath just yet. If it does come without any sort of roof, then the Sian will join an exquisite club with members such as McLaren Elva and Bentley Bacalar.

In the powertrain department, Lamborghini could leave the Sian recipe unaltered. If that’s the case, then the Sian Roadster will be good for 807 horsepower coming from a hybrid setup that twins a naturally-aspirated, 6.5-liter V-12 and a 48-volt supercapacitor system

The V-12 internal combustion engine alone cranks out 774 horsepower while the electric bits and bobs add 33 horsepower to the tally. 0-62 mph takes less than 2.8 seconds, and a 217-mph top speed can be reached provided there’s enough space for the hybrid bull to stretch its legs properly.

Other details such as price and the number of units slated for assembly are unknown, but the exclusive air of a Lamborghini roadster should see the open-top Sian’s production limited to just a handful of cars (the Sian coupe has a production cap of just 63 units), each priced at around $4 million or even more. Time will tell.

Tudor’s first encounter with cars took place when he was only a child. Back then, his father brought home a Trabant 601 Kombi and a few years later, a Wartburg 353. At that time, he was too young to know how they worked and way too young to drive them, but he could see one thing – each of them had a different ethos and their own unique personality. As time went on, he started seeing that in other cars as well, and his love for the automobile was born.  Read full bio
