Additional Notes

  • The Bentley Flying Spur 4W rear differential holds a capacity of 1 liter across all listed configurations, which is a relatively modest fill volume consistent with a sealed rear differential unit rather than a large open-sump assembly.
  • The V8 variant covers the 2013-2019 model years, while the V8 S entered the specification records from 2017-2019, reflecting a later introduction of the higher-output eight-cylinder trim within the same generation.
  • The W12 configuration in standard form spans 2016-2019, whereas the W12 E85 variant carries an earlier start date of 2013-2016, indicating the E85-compatible twelve-cylinder was available before the non-E85 W12 appeared in the records.
  • The W12 S E85 is listed from 2017-2019, placing it as the latest-arriving twelve-cylinder variant in the specification set, alongside the V8 S as a concurrent high-performance trim introduction.
  • All five configurations share the same 1-liter rear differential capacity under normal use conditions, meaning no trim level or engine type within the Flying Spur 4W range requires a differing fluid volume for the rear differential service fill.
  • The uniform 1-liter capacity across both V8 and W12 powertrains suggests the rear differential housing is a common unit across the platform, independent of the engine's displacement or fuel compatibility.
