Benchbuilt

Benchbuilt turns vehicle engineering into a hands-on learning lab. Start with a production-inspired body, choose an engine, configure the drivetrain and chassis, then shape the body and test the result.

Every choice feeds a physics-based estimate using real units and understandable explanations. Compare power, mass, frontal area, drag coefficient, traction, gearing, braking, and engine packaging without needing an engineering degree.

BUILD YOUR VEHICLE
• Choose from compact, fastback, roadster, sports sedan, and open-engine hot rod body packages
• Install engines ranging from an efficient four-cylinder to high-output V8 packages
• See whether the engine fits beneath the body or protrudes into the airflow
• Configure transmission, tires, brakes, suspension, chassis weight, and fuel
• Shape independent body control points to explore smooth profiles, wedges, and experimental designs

TEST AND LEARN
• Estimate top speed and 0–60 mph acceleration
• Measure quarter-mile time and trap speed
• Compare standing-mile speed, lateral grip, braking distance, and cruise range
• Run road and wind-tunnel tests
• Understand why drag, weight, power, traction, and gearing changed each result
• Save builds for side-by-side engineering comparisons

Designed for curious builders, students, classrooms, and anyone who has wondered why one car shape performs better than another. Benchbuilt works on iPhone and includes a spacious iPad workbench for classroom use.

Benchbuilt provides educational physics estimates and is not intended for real-world vehicle certification or safety decisions.
