Power Racing Series

Power Racing Series is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Power Racing Series rather than just read about it. In short: The Power Racing Series (PRS) is an American amateur racing series and nonprofit organization in which participants build and race electric vehicles modeled on children's ride-on toy cars. Founded in Chicago in 2009 by Jim Burke and members of the hackerspace Pumping Station: One, it expanded to Maker Faire events around the United States.

Key takeaways

Power Racing Series belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Power Racing Series to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Power Racing Series from memory before moving on to harder problems.

Reference excerpt

The Power Racing Series (PRS) is an American amateur racing series and nonprofit organization in which participants build and race electric vehicles modeled on children's ride-on toy cars. Founded in Chicago in 2009 by Jim Burke and members of the hackerspace Pumping Station: One, it expanded to Maker Faire events around the United States. Teams compete for race results and for audience-awarded "Moxie" points based on presentation and entertainment.

Competition format

The cars retain elements of a children's ride-on vehicle but can be rebuilt with new frames, batteries, motors, wheels, and controls. The series uses a capped modification budget to keep entry affordable and encourage resourceful engineering; the limit has varied between seasons, from $500 in 2013 to $600 at a 2025 event. Events have included sprint and endurance races. In addition to points for finishing position, spectators can award Moxie points for a team's theme, vehicle decoration, costumes, and other crowd entertainment.

History Burke and a friend developed the idea after finding a motorized toy car in a Chicago dumpster in 2009. Burke and colleagues at Pumping Station: One began modifying and racing similar vehicles, with six teams taking part in the first event on a vacant lot. In 2010, Pumping Station: One expanded the competition to Maker Faires in Kansas City, Missouri, and Detroit. The Detroit event included drag, road-course, and endurance races. More than 20 teams participated during the 2011 season, many representing hackerspaces in the Midwestern United States. By 2013, the series reported 29 certified teams and a five-event schedule spanning California, Missouri, Michigan, Indiana, and New York. It continued to expand nationally; a 2019 profile described events in cities across the country and emphasized the competition's role as an accessible engineering challenge. The organizing body later became a registered 501(c)(3) nonprofit and broadened its educational activities to include grants, do-it-yourself fairs, and a combat robotics league. The series remained active in 2025. A race at Maker Faire Lynchburg that year drew teams from several states, including four cars from the University of Indianapolis.

Worked examples

Example 1 — a first encounter with Power Racing Series

Start with the simplest possible case. Write down what Power Racing Series claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Power Racing Series before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Power Racing Series ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Power Racing Series

In research: Power Racing Series appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Power Racing Series in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Power Racing Series is common in secondary-school and first-year university syllabi. It links to neighbouring topics Electric vehicle organizations, Motorsport competitions in the United States, Recurring sporting events established in 2009, so understanding it makes those chapters shorter.
In everyday life: Look for Power Racing Series outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
