Greatest road tests ever: the BMW 633 CSi is often overlooked these days, but we loved it back in 1976
Engine responsiveness was superb, letting you trickle along in top at 30mph but also yielding lusty acceleration without the need to downshift and cruising comfortably at 105mph. Economy bettered the CSL by a full 3.9mpg overall.
The four-speed manual ’box was light yet positive in action, but reverse was tricky to engage and the clutch was heavy. The worm and roller steering was accurate enough with unobtrusive power assistance. Roll was well contained, understeer could be curbed with the throttle and power slides were easily held. The relatively firm ride jerked a bit in town but dialled in with pace, aside from some rear-end float. All-round ventilated discs were strong but prone to locking up.Performance, economy, handling and steering
