German for "Racing Wood," the Rennholz is an electrically powered, wooden vehicle that runs off of an ordinary [Bosch](https://www.trendhunter.com/trends/ruff-cycles-cargo-buddy) screwdriver. The project was an entrant in the HAWK Hildesheim's bi-annual race, a competition in which entrants must use [electric screwdrivers](https://www.trendhunter.com/trends/hoto-pixeldrive) to power their vehicles. The bulk of the design is made out of custom-fabricated bent plywood with a few aluminum pieces lifted off of bicycles. This wooden hot rod maxes out at around 15mph and lasts roughly ten minutes when using a fully charged screwdriver. This sleek, racer design would make an excellent addition to any [derby racer](https://www.trendhunter.com/trends/airpower-turbo-racer), switch out the screwdriver for a higher powered motor and hold on! ## Trend Insights (Trend Hunter) - Score: 6.4/10 - Popularity: 90% | Activity: 95% | Freshness: 8% - Audience gender: 90% men, 10% women - Primary generations: Gen Z, Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### Key Themes Behind This Trend - **Electrically Powered Vehicles:** Disruptive innovation opportunity: Develop more efficient and sustainable electric vehicles using unconventional power sources. - **Custom-fabricated Materials:** Disruptive innovation opportunity: Explore the use of alternative, lightweight and environmentally friendly materials for vehicle design. - **Alternative Transportation Competitions:** Disruptive innovation opportunity: Create and sponsor competitions that encourage the development of innovative and eco-friendly transportation solutions. ### Where This Applies - **Automotive:** Disruptive innovation opportunity: Integrate sustainable and unconventional power sources into the automotive industry to create more eco-friendly vehicles. - **Material Manufacturing:** Disruptive innovation opportunity: Develop new methods and materials for creating custom, lightweight and sustainable materials for various industries. - **Event and Sports Sponsorship:** Disruptive innovation opportunity: Support and sponsor alternative transportation competitions and events to promote sustainable and innovative solutions in the transportation sector. ## Related on Trend Hunter - [Electric Hot Rod Vehicles](https://www.trendhunter.com/trends/electric-hot-rod.md) - [Sleek Cordless Screwdrivers](https://www.trendhunter.com/trends/hoto-cordless-screwdriver.md) - [Sleek Electric Screwdriver Concepts](https://www.trendhunter.com/trends/delta.md) - [High-Power Handheld Maker Tools](https://www.trendhunter.com/trends/cordless-diy-tool.md) - [Reimagined Ratchet Screwdrivers](https://www.trendhunter.com/trends/ratchet-screwdriver.md) - [Pocket-Size Electric Screwdrivers](https://www.trendhunter.com/trends/voltwistv1.md) - [Meticulous Electric-Free Toy Cars](https://www.trendhunter.com/trends/grip-car.md) - [Modern Design-Conscious Power Tools](https://www.trendhunter.com/trends/hoto-36v-screwdriver.md) - [Tech-Packed Cordless Screwdrivers](https://www.trendhunter.com/trends/hoto-pixeldrive.md)
