The Cluster Architecture (CLAR) platform is a car platform developed by BMW.
It is a modular platform that incorporates steel, aluminium, and optional carbon fibre.
[2] It is designed to accommodate a pure ICE drivetrain, has an optional 48-volt electrical system in a mild-hybrid configuration, but also supports plug-in hybrid and battery electric drivetrains.
[3] It was initially called 35up but was later renamed to CLAR.
Smaller BMW cars in the B-segment and C-segment, compact MPV and smaller SUV use the front-wheel drive-based BMW UKL platform instead.
