Lamborghini's sixth Paris 2010 teaser photo

It's a shot of an exhaust pipe, which exits the concept car just below the support for the rear wing.

We've now seen all six images, and they've shown everything from vents in the bonnet to stylish flourishes atop the V10 engine, plus glimpses of the interior and what appears to be a carbonfibre wheel. The concept car is expected to be almost completely carbonfibre, very light and Gallardo-powered. 

Why is Lamborghini showing such a car? Because the next V12 supercar will have a carbon tub, and the company is keen to push its lightweight expertise ahead of that car's launch, and the impending carbon Mclaren MP4-12C. 'From the middle of the Eighties, the average weight of our cars has increased by 500kg because of active and passive safety, comfort and emissions reduction issues, and this is something that we have to change,' said Lamborghini boss Stephan Winkelmann. 'Since we cannot reduce safety or comfort in our cars, we have to reduce the weight by using new materials. The magic word for this is carbonfibre. Every new Lamborghini will make the best use of carbonfibre to reduce weight.'

He goes on. 'Design has been and always will be reason number one, and we will make sure a Lamborghini will always be recognisable through its significant stylistic features,' pledged Winkelmann. 'Regarding performance, until few years ago priorities were, in this order: top speed, acceleration and handling. In recent years this has been changing. Together with design, handling and acceleration are becoming more important. Speed is not as important anymore, because all super-sports cars are exceeding 300km/h (186 mph) and this is a speed that you cannot reach even on a race track, let alone normal roads. We think it is time to make a shift and talk more about handling and acceleration.'

‘We are working on lightweight, intelligent materials. I’ve seen a small deflector made from carbonfibre and other materials, which moves when you apply a voltage – you can open and close it with no need for a motor. It means you can change the shape of a car with different aero for handling mode, and another shape when you want maximum speed. Having something that moves by 90deg without the need a heavy, expensive electric motor is good news for us.

‘Stop-start solutions, mild hybrid systems, biofuel solutions are already in our development pipeline for potential production cars to achieve our 35% CO2 reduction.’

So expect some sort of technical showcase for the future, obviously in the form as a car as the teaser pictures preview, and hopefully with all the tech that Reggiani promised us, but still with four-wheel drive: ‘Four-wheel drive is one of our USPs,' Reggiani told CAR. 'If you don’t have 4wd with the power we now have – more than 570bhp in the Gallardo, more than 650bhp in the Muricelago – you will just get wheelspin. Wheelspin is inefficient and loses control. It’s not the right engineering solution for us.’
