[Leonidas]

Hi
Does anybody know if our Grennies are affected( fire risk)?
Apparently half a million vehicles recalled?

Only Production Date 2020 to 2022, so most Grenadiers are delivered from early 2023

maybe so, but Ineos was stocking BMW engine assemblies and parts well beforehand...

Nearly all types, all combustion engines

When I got the car,I thought the starter motor looked quite tiny for a 6 cyl/3L engine....

Does the stop/start system use this main starter motor or a BISG generator system, in which case it could account for a small main starter.

Good question, don't know

A VW Passat starter motor is used in the Bugatti Chiron.

The Ineos Grenadier petrol (which uses the BMW-sourced B58 3.0L straight-six) relies on a heavy-duty traditional starter motor rather than a Belt Alternator Starter (BAS) or a mild-hybrid "integrated" system.


While many modern BMWs using the B58 engine have transitioned to 48V mild-hybrid systems with a Belt Starter Generator, Ineos specifically chose to keep the Grenadier's electrical architecture simpler and more "mechanical" for off-road reliability.

Modern starter motors are generally much smaller than the old school.
Mostly because they use a planetary gearset to up the torque rather than a big set of windings.

Although in one of the podcasts, Lynn Calder did last year, she did say that they will be moving to the mild hybrid. IIRC it was "possibly in 2026".
