What you’re looking at is the Paris Motor Show car Lamborghini has been teasing all this time: the Sesto Elemento concept car.
The teasers appear to match up, so this is in all likeliness the car Lamborghini will be revealing in Paris. It’s most likely the technology concept Auto Guide was telling us about, and possibly the car bearing the 83X codename.
It’s quite the concept car though. Thanks to very extensive use of carbon fibre, it weighs just 999 kg. Combined with a Lamborghini V10, this results in a 0-100 kph time of 2.5 seconds, and a top speed of 350 kph. It also looks plain insane, just as a Lamborghini should. We’ll be awaiting the Paris Motor Show to get some proper photos and details on this crazy Lambo.
