An alleged invite for the reveal of a new Lamborghini supercar at next month’s 2011 Frankfurt Auto Show has surfaced online, reigniting rumors that a production version of 2010’s stunning Sesto Elemento concept car could be on the horizon.

The key is an inscription on the invite that reads: “Lamborghini: Racing Towards Frankfurt”.

Previous comments from Lamborghini CEO Stephan Winkelmann suggested that the automaker was considering launching a limited edition version of the Sesto Elemento but that it would only be suitable as track-focused race car, as getting the carbon fiber infused car homologated for road use would be too difficult and expensive.

Such a possibility does not seem so farfetched considering the concept car is based around the Gallardo LP570-4 Superleggera platform. The only major difference is the Sesto Elemento is constructed from a new material called forged carbon, which helps keep its weight down to less than 2,200 pounds.

Additionally, with Lamborghini only taking the covers off the new Aventador LP700-4 back in March, it’s still too early for the automaker to introduce its second volume model, the replacement for the Gallardo.

NEW YORK (CNNMoney) -- Lamborghini's Sesto Elemento concept car, unveiled at the 2010 Paris Motor Show, will go into production at a price of about $2.2 million, the automaker has announced.

Only 20 will be built but there's one thing you should know before you sign up for yours. You won't be able to drive it on the street.

The production car will be virtually identical to the concept, which means it won't have airbags or other safety equipment required for legal use on roads in the U.S. or Europe. This car is strictly for use on a track.

Powered by a 570 horsepower V10 engine, the Sesto Elemento is made almost entirely from lightweight but very expensive carbon fiber. The body, its wheels and part of the suspension system are made from carbon fiber. The car weighs about 2,200 pounds, which is less than a Honda Fit subcompact.

Lamborghini boasts that the car can go from zero to 60 miles an hour in just 2.6 seconds

A rare Lamborghini Sesto Elemento with only delivery mileage is up for grabs at an exorbitant price tag.

One of the only 20 cars produced, Lamborghini's Sixth Element is certainly one of the most desirable track-only vehicles ever made not only because of its radical design, but also due to its astonishingly low weight of just 999 kg (2,202 lbs). It's powered by the familiar V10 5.2-liter normally aspirated engine which in this application delivers 570 PS (419 kW) and 540 Nm (398 lb-ft) of torque.

With so much power in such a light package, it's no wonder the 0-62 mph (0-100 km/h) sprint takes just two and a half seconds while top speed stands at more than 186 mph (300 km/h). This is one of the fastest accelerating cars in the world and according to the ad this particular unit is the only one for sale in the world.

Lamborghini asked almost €2 million for the Sesto Elemento, but this seller wants €3 million for his unused car. We won't be too surprised if the future owner won't drive it at all and in a few years will decide to sell it for more.
