Lamborghini could be producing a limited number of Sesto Elementos, albeit as track-only cars.
The car is currently undergoing testing, and based on the results of that, Lamborghini will make a production decision. However, the car would have to be limited to track use because of issues making it road legal.
If it does reach production, it could carry a price tag even higher than that of the Reventon, which cost about $1.3 million USD. No more than 20 would be made.
