CR18
2022
CR18 builds on the strengths of CR17 by retaining the chassis shape as well as the suspension set-up. CR18 boasts a brand new aerodynamics package along with a new exhaust layout and new plenum design. A small detachable hatch along the front of the car allows for easier access to the pedals and cockpit area. As well as a newly created loom allows for a multitude of sensors to monitor everything from engine temperatures to wheel speed. Carrying over design philosophies from the previous years car it helped CR18 get a head start and more time to be spent optimising the new aero package. Early design and build also meant that a good amount of testing was able to be completed before competition and the drivers could practice specific events in the new car.
CR18 marked the 20th anniversary of Cardiff Racing, hence a special livery with many aspects of previous cars liveries was made for the car. This along with a unique car launch celebrating Cardiff Racing's past success and hopefully future success was held before sending the car and team to Silverstone.
Expectations were high at Silverstone, Cardiff Racing had finished 4th last year and been a favourite to win before failing to finish endurance. The team had experienced drivers and a strong group of students who knew the car very well. Starting the events, the team was a front runner in all the statics coming no lower than 21st picking up good points across the board. The car sailed through scrutineering with only minor issues, even managing to pass the break test on the first attempt. During dynamic events CR18 topped the Acceleration event with time of 4.175 Seconds, however a less competitive time in skid pad and then an electrical issue on the 15th lap of Endurance forced the team to retire from the event just after the half way point in the session. At the end of FSUK, the team finished in 5th place overall and plenty of ideas on how to improve our result for next years car.
