See how a car engine and suspension move with animated 3D models. Car Engine and Suspension is a visual exploration app for automotive enthusiasts, students and anyone curious about mechanical systems. EXPLORE A FOUR-CYLINDER ENGINE Observe an inline engine in motion, including pistons, connecting rods, crankshaft and valves. Use the transparent view to see internal components working together. EXAMINE THE SUSPENSION Watch the suspension assembly move and explore the available controls for wheel geometry, springs and damping. Compare the movement of the components as you adjust the model. LOOK MORE CLOSELY Rotate and zoom the view, and use slow motion to examine the animations at your own pace. This app focuses on observing and exploring its included models. It does not offer an engine builder, a collection of different engine types or step-by-step vehicle repair instructions. Includes advertising. No account is required to explore the models.

Verdict
The clearest difference is ads: Engineering HandBook at none against Car Engine and Suspension's shown. Engineering HandBook also leads on update cadence (every 2 weeks vs every 18 months) and monetization model (free vs ad-supported). Car Engine and Suspension's advantage is ratings volume (73 vs 4) and rating (4.2 vs 4.0). On price, in-app purchases and device support there is nothing between them.
