An automotive powertrain is mainly responsible for the transfer of power from the transmission to the wheels. The automotive powertrain consists of many components including drive shafts, differentials, CV joints, U joints and axle shafts. All these when assembled are known as the powertrain of the vehicle. The selection of the type of automotive powertrain component depends on the type of vehicle and the power output of the engine. Furthermore, the type of automotive powertrain components to be selected also depends on the type of drive — if it is a rear-wheel drive, front-wheel drive, four-wheel drive or the less common eight-wheel or six-wheel drive. Numerous lightweight materials have been introduced to reduce the weight of such automotive powertrain components and aluminum is one such material which is gaining popularity in the automotive powertrain components market. Automotive powertrain components are designed in such a way that they can incorporate a wide range of operating temperatures, high shock resistance and vibrational strength, high reliability and long term stability. These components are usually sold through two sales channels, these include: OEM and aftermarket. With advancements in technology, the key manufacturers are focusing on manufacturing lightweight automotive powertrain components with improved performance characteristics. This is expected to create opportunities for the augmentation of the automotive powertrain components market in the coming years.
