Product: BYD crystal gear lever

Project location: Shenzhen, China

Time: 2021

Product Introduction:

1. Design Features

Material and Craftsmanship: BYD crystal gear levers are mostly made of crystalline glass material, which has good transparency and glossiness, appearing crystal clear and full of texture. After precise cutting and polishing processes, the surface of the crystal gear lever is smooth and delicate, with rounded edges and corners. It not only gives people a high-end luxury feeling visually, but also brings a comfortable touch when touched.
Styling and appearance: In terms of styling, the crystal gear lever is usually designed to be delicate and compact, blending with the overall interior style of the car. Like the crystal gear lever of BYD Sea Lion, with a simple design and two water cup holders at the back, the lower part has been hollowed out, which is both beautiful and practical. Some gear levers will also be designed with unique textures or patterns on the surface or inside, such as Pixiu patterns, technology patterns, etc., to increase the aesthetics and recognition of the gear lever.

2. user’s experience

Convenience of operation: The design of the crystal gear lever does not sacrifice the convenience of operation. The position and grip feel of the gear lever have been carefully designed, making it easy for the driver to shift gears during driving. Some car models are also equipped with physical buttons around the crystal gear lever, with a reasonable layout and easy operation. For example, the crystal gear lever of the BYD Song Pro DM-i has a wireless charging area in front, a dual cup holder and a central armrest at the back, which is convenient and practical.
Technology and atmosphere creation: When the vehicle is started, the crystal gear lever emits a charming light under the ambient lighting inside the car, creating a highly technological and luxurious interior atmosphere, bringing unique visual enjoyment to the driver and passengers, and enhancing the overall level of the vehicle.
