The Formula Student competition allows engineering students to design, develop, and build forward-looking race cars in a bid to secure jobs in top-rung series like IndyCar, WEC, and Formula 1. It’s a great format, and often really does produce some seriously innovative ideas. Even so, it’s rare for outsiders to get an up-close-and-personal look at a Formula Student race car.
For fans of crazy race cars, though, it’s Christmas in July- because Racecar Engineering magazine just published an incredibly detailed look at Team Delft’s all-electric DUT15 racer, and the Delft guys released their own excellent and informative video (above) showing how their advanced, aerodynamic contender comes together.
I won’t re-print the RE article here (that would be crazy illegal, anyway), but I will give you a sense of just how far they get into the DUT15 by including their “DUT15 Specs” table and a sample of the type of photos and captions they included to entice you to go over there and checking out the DUT15 for yourself. Enjoy!
