Intro to Racecar Engineering: 01 Getting Started

Robert "Smitty" Smith walks us through the basic principles of racecar design. This is the first of a series of videos developed for UCI's racecar engineering program. (Smitty and the Professor series)

We did well at the completion at the Holy Ground of the General Motors Proving Ground in Michigan. Among other things we had the most comfortable seats that were not from an existing car.

    Excellent video here. Must be made required viewing to any FSAE participant. As a past FSAE competitor, I have to second the professors lament about driver ergonomics. It gets neglected. Secondly, coming full circle from drivers back to tires; teams with tall/heavy drivers (ave american male…) will be needing 13” wheels to fit all the ither stuff (brakes, bearings, linkages) However, challenge yourselves early on. Teams would do well to strive for small/light driver selection (yes, it is an exclusionary process), and heavy consideration to 10” wheels, it makes design of everything else more challenging, but you will require a smaller engine, have a lighter overall car (@ minimum wb) and if all done well you WILL WIN the events that heavy larger wheeled cars cannot win. My team ran 13”/8”wide hoosiers. They never got warm. 7” wide barely after 30 min of autocross. Also i’m 6’3” I could not confortably fit my feet in the pedalbox. Failure. FSAE WAS FUN!

    Great info for guys looking to learn. I especially appreciate the comment about driver consideration at the end. I see some guys who are great fabricators build these awesome car setups and then the driver position looks absolutely horrible. I would argue that ergonomics may be more important than certain design elements which may make the car physically capable of going faster. If the driver doesn’t feel confident and have the ability to execute fine levels of control the lap time will probably suffer more.

    The difficulty with all of this is you end up with a lot of racecars which look the same and that in turn, IMO, is part of the problem with falling interest. On the flip side is something like SCCA where cars can look considerably different but then you are working to a large degree with what the OEM decided was their design and all the compromises from handling characteristics involved adding in any rules regarding change. And even with SCCA, as an example, given racecars are going to, over time, begin to dominate which will lead to copying of those known to work well assuming one is trying to get to the podium. IF this is all just being done as an exercise for learning, great.

    This is how evolution works. This is why some animals, like sharks for example, haven't changed for 200 million years. There is an optimum setup for every task. You want to be succesful at a certain task, you have to get closer and closer to the optimum. Otherwise you will be taken over and left behind.

They can just go buy all the parts, assemble them and go participate. Skills are lost or never learned in the first place. So at some point that evolution will come down to who has the biggest wallet. NASCAR is a perfect example, interest declined when 3/4/5 car teams began to dominate. Real big money, as in sponsors, needs spectators and TV viewership.

    Do you define track width as wheel mounting surface to wheel mounting surface, or from the outside edge of the tire to the same on the other side? Depending on tire width and wheel offset/backspacing, this could make a huge difference on the accuracy of someone's track width to wheelbase ratio. *EDIT:* Lol, I had paused the video to ask my question literally 4 seconds before it told me. Nice. (It's center to center of the wheels BTW, for anyone watching. So technically neither of my examples unless the wheels also always have 0 offset.)

    I drove a Formula SAE car and the cockpit was so badly designed that it was almost undriveable. We had to sit bent at the hips at 90 degrees with no elbow room and a small steering wheel placed so low that it hit our knees when we turned it! To make things worse the turning circle wasn’t enough and the car couldn’t get around the hairpin. It was really embarrassing for the team. It’s very important for car/race car engineers to understand that that if the driver is uncomfortable, ergonomically compromised or in pain, then the car performance will suffer and all the effort will be wasted 🙂. Just a bit of advice from my experience racing.
