McLaren's latest supercar comes without a roof, windows, or windshield, yet you shouldn't have to worry about swallowing bugs. The Elva roadster, which can reach 60mph in under three seconds with a 804-horsepower turbocharged V-8 engine, is equipped with what's called an "Active Air Management System," triggered at speeds over 25mph. Per CNN, air is funneled through a vent in the car's front end and expelled "in a high-velocity sheet, just ahead of the cockpit." In other words, the air itself acts as a windshield. You can add a real windshield, as one is required to drive in certain US states, but the cost is added to the car's $1.69 million price tag. Motor1 reports just 399 cars will be made and delivered beginning at the end of 2020. (More cars stories.)
