When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics ...
When a driver steps on a brake pedal, the kinetic energy of the moving car is turned into friction between the brake pads and rotors (at 60 mph, there’s enough energy in a 3500-pound car to keep ...
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
Part of the magic of this high-performance sports car is how each model in the lineup feels both unique and uniquely Corvette.From the 490-hp Stingray to the first-ever all-wheel-drive Vette in ...
The Performance Data Recorder (PDR) is an optional system that allows Corvette drivers to record performance data while driving and review the results. [32] A 720p high-definition camera mounted within the windshield header trim records the driver's point-of-view through the windshield, with audio recorded via a dedicated microphone in the cabin.
