Automotive retreaded tires, also known as remolded or reconditioned tires, are used tires that have undergone a process to replace the worn-out tread with a new layer of rubber. This process involves carefully removing the old tread from the tire casing, inspecting the casing for any damage or defects, and then applying a fresh layer of tread using specialized machinery.

An automotive camless engine is defined as an engine configuration wherein the poppet valves are operated using pneumatic, electrohydraulic, or electromagnetic actuator systems instead of conventional cams. The intake or exhaust valves are operated using this camless arrangement of the camshaft, which incorporates the use of springs or other means. This type of engine configuration has been recently developed by engine designers and developers for achieving optimum performance and fuel efficiency in addition to reduced carbon emissions.

Automotive communication protocols are standardized sets of rules and conventions that facilitate communication between various electronic components and control systems within modern vehicles. These protocols enable different parts of a vehicle to exchange information and data, such as engine diagnostics, safety systems, and entertainment features.

The automotive clutch actuator is a device used in vehicles with manual transmissions to engage and disengage the clutch. It is responsible for controlling the movement of the clutch mechanism, which connects the engine to the transmission. The clutch actuator is usually a hydraulic, pneumatic, or electromechanical system that is activated either by the driver pressing the clutch pedal or by an automated system in vehicles with automated manual transmissions (AMT) or dual-clutch transmissions (DCTs). The actuator applies force to the clutch mechanism, allowing the clutch disc to either engage or disengage from the flywheel, thus enabling smooth gear changes and the transfer of power between the engine and the transmission.

An autonomous car operates without human intervention or with very little human intervention. In this report, autonomous cars include only those cars with autonomous levels of 3 or above. Autonomous car software helps in the autonomous driving of the car.
