The lightweight nature of our cars also results in high fuel efficiency: last year we placed 2nd in the Efficiency event at competition, with the only car to beat us being electric.
As the M015 pursues a lightweight philosophy, the team had a rethink of our aerodynamic direction, which yielded a different concept entirely. Instead of the full package as seen on the M014, we now have a large ‘underwing’ working in line with a diffuser. This shift to a more ground-effects based package results in large gains in aerodynamic efficiency (lift to drag ratio), and significantly lowers the centre of mass of the car. This tied in well with our simple and lightweight design, more so than a relatively heavy wing package. The lightweight nature of our cars also results in high fuel efficiency: last year we placed 2nd in the Efficiency event at competition, with the only car to beat us being electric. Moving to a highly efficient aerodynamics package should maintain our high scores in this event, while also resulting a faster car overall. This week, we’ve been working in collaboration with Greenmount Espies, who specialise in turn-key interior fit out solutions. Greenmount have been a huge sponsor of the team in past years, normally machining the plugs for our monocoque. This year, they were kind enough to assist us in the manufacture of the molds and plugs for our aero package using a Routech 5-axis CNC Router. Team members helped layer and glue together profiles cut using the router, and then the router was used to finish the piece. We had members from the team go into their workshop every day this week, learning what goes into making a mold and helping with the process, and it was incredibly satisfying seeing a finished mold come out the CNC!
