THE HISTORY OF CLEAR RIVER RACING

Our growth have been immense over the last couple of years, take a look yourself!

In the beginning of CRR´s history we started with 4-cylinder engines and were not equipped with aero-package. The first car to add aero-package were CRR13 which also was the last car with a 4-cylinder engine. All of our cars are equipped with aero-package since 2013. From 2014 we began to use a 1-cylinder KTM 500 engine and later in 2016 and 2017 we added a turbo charger for more power.

In 2018 we took a big step and manufactured our first hybrid chassi with a carbon fiber monocoque and a rear steel tube frame. This was a difficult task but still worth the effort. 2018 car used the same engine type as CRR16 and CRR17 but without the turbo charger, this to reduce weight. For 2019 we are manufacturing our second monocoque and aspire to improve the development for every year coming.

CRR21 was a remarkable car, this is our first ever electrical formula student car. It’s a huge step into the future of Clear River Racing. It started with two hub motors and a battery pack we built ourself. We are looking forward to what the future has in store for Clear River Racing.
