Lamborghini used Monterey Car Week to unveil the Aventador SVJ 63 Roadster and Huracán EVO GT Celebration, but it appears the company is saving something special for Frankfurt.

In a tweet, the automaker teased a mysterious new model which features a double bubble roof and angular LED daytime running lights that mimic those used on the 2017 Terzo Millennio concept.

Speaking of the latter, the resemblance to the Terzo Millennio is striking as both cars have a low ride height, a similar roof design and nearly vertical front fenders. However, we know the cars are different as the inner LED lights on the Terzo Millennio were flat while the ones on this model angle downwards.

Lamborghini is staying tight-lipped about the car, but hinted “Something new is waiting for you. Open your eyes to the future and you’ll see it.”

While the company is playing coy, previous reports have suggested the model could a limited edition hypercar that draws inspiration from the Terzo Millennio.

Little is known about the model, but it’s reportedly codenamed the LB48H and will feature a hybridized powertrain with a V12 engine. That remains unconfirmed, but rumors have suggested the Aventador successor could be offered with a plug-in hybrid powertrain that combines a naturally aspirated V12 engine with up to three electric motors. This could potentially enable the car to produce around 1,000 hp (746 kW / 1,014 PS).

Getting back to the hypercar, it’s rumored to cost around $2.5 (£2 / €2.2) million. It was reportedly shown to prospective buyers last year and could already be sold out.
