By now you've likely seen an image of the Ferrari LaFerrari a thousand times, but can you spot the subtle difference on the LaFerrari in the video below? We'll give you a second to figure it out.

In case you can't see it, most of the front bumper is painted the same color as the body, which is not the case on the standard car. Check the images below for a side-by-side comparison.

It doesn't seem like much, but the timing is odd. We know Ferrari is currently working on a successor to the LaFerrari, and this is the first time in a while this supposedly well-known test mule has left the factory.

What you might have missed is what appears to be a triangular warning sign on the hood. That's the universal sign for electricity, which is odd. All of the LaFerrari's hybrid-assist components were located behind the cockpit. There's simply no need for that warning unless the engineers are afraid of getting shocked by the wiper motor. From the rear, it looks the same, however.

We do know Ferrari is using modified LeFarrari and LaFerrari Aperta bodies to test the underpinnings of the Prancing Horse's next-generation hypercar.

The other test mules we've seen so far have a different front fascia and new air intakes. The LeFarrari's hood intake is also missing, and the side vents are noticeably smaller. Timing-wise, it adds up. A new Ferrari halo model arrives once every ten years, which means an all-new model is due in 2022.

There are also rumors that Ferrari is working on a new Dino, powered by Maserati's all-new 3.0-liter twin-turbo V6 engine. However, we doubt that car has anything to do with this, as that particular test mule has also been snapped in action.

The most logical explanation is that the Ferrari in this video is a test mule, possibly testing a larger battery pack now located at the front. Out of the three cars that made up the so-called holy trinity, the LaFerrari was the only car that couldn't run on electricity alone. The other two were the McLaren P1 and Porsche 918 Spyder, in case you forgot.

If Ferrari wants to keep the V12 alive for one last blast before its inevitable demise, this seems like the most obvious way to do it.
