# Why Has No Production Car Hit 300 MPH? Electric Cars

Hello everyone and welcome! This is the fourth of a Five-Part Series where I have partnered with Formula E to talk about electric car technology and in this video we’re answering the question could an electric production car be the first to hit 300 mph. Now the premise for this video stems originally from an older video I did asking the question “Why has no production car ever hit 300 miles per hour?” And in this video we learned a big part of why cars haven’t hit this 300 mph mark is because of the drag, the aerodynamic drag placed on the vehicle. And with internal combustion engines you need a lot of cooling, and that cooling means you need additional drag because you have to pass air through the vehicle. And so a lot of people in the comments asked you know “Would It be easier to achieve this 300 mph goal using an electric car?” Because they’re far more efficient and then perhaps they wouldn’t have that aerodynamic drag because they wouldn’t need as much cooling. So that’s what we’re going to discuss in this video. Now as was discussed in the previous video this is our equation for power, how much power we will need to reach a certain speed. That’s being V for velocity here in this case 300 mph. Now you have to break this down into three different sections. Here we’ve got drag, rolling resistance, and your drivetrain efficiency. But The biggest part of what’s going to cause you to need a lot of power to reach a high speed is aerodynamic drag. And so If you look at this equation right here the most critical component is this coefficient of drag multiplied by the front surface area of your vehicle. Because as you can see it’s multiplied by V squared and V. So you have to multiply the coefficient of drag by the frontal area of the car by velocity cubed. So as speed gets higher the amount of energy you need to overcome that aerodynamic drag goes up by velocity cubed, so obviously it’s extremely important to minimize the coefficient of drag in the frontal surface area to keep this number right here low so you don’t need all that much power. Now with internal combustion engines, this coefficient of drag is heavily influenced by the cooling system because you need all of that extra air to cool down you know the engine, the transmission, things like that, and so could you know an electric vehicle have an advantage in this scenario?
