Why McLaren Elva doesn’t need a windshield: video

The British magazine Top Gear spoke in detail about the speedster McLaren Elva, including showing how to create an “air dome” above the head of the driver and passenger at high speed. The Active Air Management System (AAMS) is an innovation not only for McLaren, but for the entire industry.

Stripped of a roof and even a windshield, the Elva became part of the Ultimate Series, the most expensive and extreme in the McLaren portfolio. At the heart is the carbon fiber monocoque Monocell II, like other supercars of the brand, covered with carbon panels. These massive elements reach three meters in length. Their thickness is only 1.2 millimeters. But the main thing in speedster is the system of active air flow control, which allowed to save the driver and passengers from the annoying wind.

The main element of the McLaren Active Air Management System (AAMS) is the carbon fiber deflector on the hood. With increasing speed, it rises and creates a zone of low pressure. The dispersed air taken through the hole above the splitter is picked up by the flows flowing around the car (ejection effect) and enters the undisturbed environment, creating something like a “bubble” above the cockpit. However, AAMS can be deactivated, and as an option to order a kind of windshield for a supercar.

The McLaren Elva is powered by a 4.0-liter twin-turbocharged V8 engine. The engine with a flat crankshaft and dry sump lubrication system produces 815 forces and 800 Nm of torque and is paired with a seven-speed preselective “robot”. From zero to 100 kph the speedster accelerates in less than three seconds, and up to 200 kilometers per hour – in 6.7 seconds, faster than the track Senna.
