Benchbuilt vs WindFlow

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.

Play with cars and planes in a 3D wind tunnel on iPhone. Watch the air flow, compare shapes, learn drag. Import your own print when you’re ready. Record a clip to share. On-device screening estimate — not a lab test. No account. Gallery free. WATCH THE AIR Pick a gallery car, plane, or blunt shape. Tap Run. Smoke and streamlines fill a 3D tunnel on this iPhone. Orbit, clip a cross-section, and compare a brick to a slippery silhouette. RECORD A CLIP After a run settles, open Record. Capture the stage as a short video (including 9:16), then share to Photos, Files, or Messages. Recording stays on this iPhone until you choose to share.
