The all-new Audi A7 is equipped with a 7-speed Stronic dual-clutch transmission paired with a V6 turbocharged engine, while a traditional 8-speed automatic transmission is provided for the diesel models that require higher torque.
Positioned between the C-Class executive/business cars and D-Class luxury vehicles, the Audi A7 is a four-door sporty luxury coupe that is slightly larger than a non-extended C-Class sedan and smaller than a D-Class luxury car.
The Audi A7 Sportback pursues a minimalist and elegant design, featuring a soft yet tight surface with distinct contours that exude dynamism. As De Silva summarizes, like other models in the Audi brand, the design of the A7 Sportback emphasizes a sense of wholeness, appearing as if it is crafted from a single piece of metal.
All lines and surfaces on the body are clear and concise, without any superfluous elements. At the same time, a car should not merely be a cold industrial product; people desire certain emotional elements.
The Audi A7 Sportback not only continues the family design language but also enriches the emotional characteristics of the Audi brand. The primary function of the transmission is to alter the engine's speed and torque, consisting of a transmission mechanism and a control mechanism; some cars also have a power output mechanism.
The transmission mechanism typically uses conventional gear transmission, while some employ planetary gear transmission.
The most common type of transmission is the stepped transmission, which uses gear transmission and has several fixed transmission ratios.
Depending on the type of gear set used, transmissions can be classified into fixed-axis and rotating-axis types.
Cars and light to medium-duty trucks typically have transmissions with 3-5 forward gears and one reverse gear, while the combination transmissions used in heavy-duty trucks have even more gears.
The number of gears in a transmission refers to the number of forward gears it has.
