他們測試這個舒適度是開30-mile然後也不是單純低速市區這樣測試 Our judgments are based on a 30-mile loop at predetermined speeds on a course that includes a variety of roads with bumps, ruts, and undulations, and also a typical highway section. Our engineers noted whether the suspension absorbed and isolated appropriately. Our testers determined whether the ride was stiff, choppy, tender, or floaty, and how well the car coped with pavement flaws. CR testers were on the lookout for adverse ride motions such as side-to-side rocking. The CR team’s experiences from commuting in the test cars also were factored in.
