Additional Notes
- The Talbot Sunbeam rear differential holds 0.85 liter of fluid across all listed variants, spanning the 1.0, 1.3, 1.6, 1600 Ti, and Lotus engine configurations from 1978-1981.
- Every variant in the lineup carries a "filled for life" designation for the rear differential, meaning no scheduled drain-and-refill interval is specified for the fluid itself.
- Despite the filled-for-life status, a check interval of 7500 km is assigned to all variants, indicating the fluid level is still subject to periodic inspection rather than being entirely ignored between services.
- The 0.85 liter capacity figure represents a service fill volume, reflecting the amount of fluid the rear differential housing holds under normal operating conditions rather than a full overhaul or dry-fill quantity.
- The 1600 Ti is the only variant with a model year starting in 1978, while the 1.0, 1.3, 1.6, and Lotus variants all begin from 1979, yet all share the identical 0.85 liter capacity and 7500 km check interval.
- The uniformity of the 0.85 liter capacity across the Lotus variant and the standard-engine models suggests a common rear differential unit was used regardless of the significant power difference between configurations.
