Lamborghini Huracan Successor Starts Engine After Reversing in Electric Mode

We apologize for the wind noise, but we couldn’t resist sharing a spy video of the Lamborghini Huracan successor being tested in Spain. The “baby Lambo” is remarkably quiet in the beginning of the clip because it will be a plug-in hybrid, similar to its big brother, the Revuelto. Around the 1:00 mark, we finally hear the engine before the car reverses in electric mode.

The most exciting part of the video occurs at 1:14 when the driver restarts the internal combustion engine. Unfortunately, it does not feature the naturally aspirated V10 found in the Huracan and Audi R8. Recent reports suggest that it will have a downsized engine, potentially a twin-turbo V8. Rumor has it that the turbochargers will not engage until 7,000 rpm, so for the most part, the engine will behave like a naturally aspirated one. The redline is expected to be at 10,000 rpm.
