Lamborghini made it clear last year that it’s working on a new supercar to replace the V12-powered Aventador. And the car shown above is definitely a new Lamborghini of some sort. However, we don’t think this is the Aventador replacement. Instead, we suspect this is another limited-run Aventador-based special model.

The key tipoff is the greenhouse. All the glass looks just like the pieces found on the Aventador, the Countach, the Sían and plenty of other special Aventador models. Similarly, the proportions of the car match those models, too. And Lamborghini has said that its full Aventador replacement will be a completely new car with a completely new powertrain. So nothing leftover from its predecessor.

There are of course styling features not shared with other Aventador-based cars, so it will still probably be a unique model. The front end has particularly angry eyebrows over the lights, and they appear to intersect with the lower grille openings. Interesting aerodynamic panels behind the windows also show up. The rear is the most distinct with high-mounted quad-exit exhaust right in line with slim taillights. Note, the “lights” lower in the rear are just printed on the camouflage.

This prototype also tips us off to the powertrain. On the outside are high-voltage warning stickers. And since it seems to be a special Aventador-based model, we bet it’s using the same hybrid V12 used in the Countach and Sían. Output should be around 803 horsepower, maybe a little more from the naturally aspirated V12 and a small electric motor powered by a supercapacitor.

We’re expecting the car will be revealed within a year, since it looks pretty far along in development, and it’s based on a car whose days are numbered. We don’t have a name yet, but Lamborghini recently trademarked the name Revuelto, which could be used on this model, or on that planned Aventador replacement.
