BMW E46 318i — analogue, adjustable, deliberately usable.
A road-based rear-wheel-drive track-day car that keeps the useful parts of the original BMW cockpit while adding targeted mechanical and chassis changes.

Why it matters
The original adjustable seating and restraint arrangement makes entry, exit and driver changeover simpler than a fixed competition cockpit. It also provides a wider range of seat adjustment for different heights and body sizes and may better suit some drivers who benefit from easier access or additional seating flexibility.
