These automotive components represent a design choice where the exterior door activation mechanism sits level with the surrounding body panel. This contrasts with traditional designs where the handle protrudes. An example is a handle that retracts completely into the door surface, offering a smooth, uninterrupted profile.
The integration of such mechanisms into vehicle design provides several advantages. Aerodynamic efficiency is improved due to reduced drag, potentially leading to better fuel economy. Aesthetically, they contribute to a cleaner, more modern appearance, often associated with luxury and high-performance vehicles. Historically, these handles were initially seen on concept cars and high-end models before becoming more widely adopted across various automotive segments.
