How Mercedes-AMG Cools Its Cars in Formula One

As many of you know, modern Formula One cars are of an entirely different breed than single-seaters of yesteryear, whether from F1 or other motorsport disciplines, but we're willing to bet that most of you aren't aware of all the details that make them truly special.

Sure, most F1 aficionados know that starting from the 2014 season we no longer have “simple” high-revving engines in a Formula One car, but a melange of a 1.6-liter V6, an electric motor, an electrically-assisted turbocharger and a battery, all working together.

As you can imagine, the new “hybrid power units” - as F1 teams call them – are dissipating quite a lot of heat, but until today we had no idea that the cars themselves are as hot as an oven and in the most inconvenient places.

For example, the drivers can experience up to 75 degrees Celsius (167 degrees Fahrenheit) inside the cockpit, while the sidepod radiators have an operating temperature of over 120 degrees Celsius (248 degrees Fahrenheit).

Some of you may have seen that when the car is inside the garage, both the sidepods and the roll-hoop above where the driver sits are cooled using centrifugal thingamajigs that look pretty much like exterior turbines.

There are a number of brands which provide these cooling solutions in Formula One, and Mercedes-AMG Petronas recently signed a partnership with the world-leading fan and motor providers from ebm-paps.

“Formula One is the pinnacle of automotive innovation. As such, it has a duty to push the boundaries of technology. The new regulations not only encourage this innovation but also make the sport more relevant to the direction in which the motoring industry is heading.” said Toto Wolff, Head of Mercedes-Benz Motorsport.

“Our partnership with ebm-papst not only provides the team with the best solutions available to operate our racing cars but it also demonstrates the significance of new and innovative technologies within the sport. To welcome a new partner as a direct consequence of the new 2014 rules is proof that we are heading in the right direction. Our research and development for the race track is now increasingly relevant not only to our road car activities but also wider fields of technology.”

The peeps from ebm-papst have already developed off-board cooling solutions for the F1 W05 single-seaters, in addition to providing custom-built heat extraction and cooling solutions for the garage working environment during Grand Prix weekends, technologies which will be introduced later in the 2014 season.
