Below is a CAD model of a flat 4-cylinder engine, belonging to a Porsche.

Solution

My car engine is straight with three cylinders, which has a relatively higher CG compared to Porcshe as shown above. With lower CG height the engine Porsche will have better dynamic stability as well as less frontal area which will reduce the aerodynamic drag which again in turn results in better dynamic stability.
