Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
As a result of increased sales of full electric vehicle and hybrid electric vehicles in several countries, some members of the blind community have raised concerns about the noise reduction when those vehicles operate in all-electric mode, as blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets and think quiet hybrids could pose an ...
Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]
A burnout is when a car intentionally locks the front wheels to hold the car in place while spinning the rear wheels. The dynamic friction of the spinning tire against the road causes significant amounts of the tire's rubber to be deposited onto the road surface, and increased temperature from friction usually creates dense white smoke.
During fishtailing, [2] the rear end of the car skids to one side, which must be offset by the driver counter-steering, which is turning the front wheels in the same direction as the skid, (e.g. left if the rear swings left) [1] and reducing engine power. Over-correction will result in a skid in the opposite direction; hence the name.

The system is active up to 31 miles per hour (50 km/h) and steers, brakes, and accelerates the car on its own. [77] It relies on the adaptive cruise control sensing a car in front and clear lane markings to be present. 2016 Audi: Audi A4: Semi-autonomous traffic assistant marketed as "Traffic Jam Assist" offered as an option.

The blue car's driver sees the green car through the mirrors but cannot see the red car without turning to check the blind spot (the mirrors are not properly adjusted) As one is driving an automobile , blind spots are the areas of the road that cannot be seen while looking forward or through either the rear-view or side mirrors (expecting that ...
