Grenadier misses yet another promised sales date

The N57 BMW 3.0 diesel engine model, which is fitted to the Grenadier, seems to be plagued by catastrophic faults when used hard commercially.


From BBC News this evening 15th Jan 2023
BMW have withdrawn the sale of their cars to UK police forces apparently.

I do believe that many farmers will tow heavy loads putting at least as much stress on Grenadier engines as the police do. I wonder whether current production of BMW engines are more durable and reliable than previously?

From Wikipedia today https://en.wikipedia.org/wiki/BMW_N57


While this engine has been somewhat modified for current production and is now designated B57, the fact that it has withdrawn new BMW cars from police and specialist fleet duty sales must be very significant indeed.

The issue with the BMW diesel engines is allegedly that the plastic inlet manifold gets polluted internally with oily soot and has been known to catch fire when used hard at full load. This resulted in a whole spate of police car fires and the death of one officer as explained in the BBC link above.

I believe that Grenadier should come clean about this and explain what BMW have done to prevent further such incidences in current production B57 engines that are hard driven, if anything. I’m fairly optimistic that BMW, with their engine reputation, will indeed have sorted this problem some time ago and that the withdrawal of police car sales [they have dominated nationally in recent years] is due to a lack of confidence by police forces rather than a lack of confidence by BMW in their current production engines.
More than one issue with that engine when worked hard from what I've read.
 
Aye, but will it try killing you and all life forms within a quarter mile radius every time you touch the throttle mid bend?

I miss how scary those things were to drive 🤣

Only time I've been genuinely frightened in a car was in a Noble. I wasn't driving, it swapped ends coming off a roundabout in the rain, right on a normally busy roundabout in Poole on the A350. Luckily nothing else was following on behind. Started up and drove off home to change our pants.

It seems the cars melt when there is work to do, just like the cops that drive them.
Does seem that way. From what I've read it's blamed on the fact that the police are the only people driving them that can drive them hard for long enough for some of the problems to arise yet in Germany where they have the autobahn you don't hear of the issues 🤷‍♂️

Fro the articles I have read, the engine problem experienced by the police seemed to be entirely the fault of the engines spending hours and hours sitting at idle. It was stated than only the police were having problems, and non of the cars sold to the public and used conventionally experience failure.

Glazing the bores?
The piece I read said it was about oil in the manifold igniting.

Actually, the unusual way police cars are operated relates to the way pursuit driving is done, not idling. My friend was a Met copper for 30 years and failed his police Class 1 3 times for lacking aggression. They teach that you should always be in the lowest possible gear for the speed you are doing and thus the engine is revving hard (because you then have great speed control by simply lifting off the throttle). VERY few civilian cars ever operate like that.

Thank you for that, interesting.

I really am amused by the comments on this super vehicle.
Yes the UK,EU & USA are phasing out fossil fueled vehicles in the next ten or so years.

But the rest of the planet have no .yes NO intention of following this course of action.The market for the Grenadier is the rest of the world.Many many countries still do not even have electric power to farms & villages,let alone persuing the woke agenda.IMHO Sir Jim is thinking long term,and well done.
In the next 10 years we wont have the generating capacity or the electricity transmission network in place to replace fossil fueled vehicles so take these dates with a pinch of salt. Its not going to happen. Do you see any streets being dug up now to install home charging points?

I doubt it myself but the vast majority of NEW passenger cars sold by 2030 will be electric. However it is likely to be at least 2035 before over half of all vehicles on the roads will be plug-in all-electric. Very few internal combustion cars running on petrol or diesel will be on our roads regularly by 2045/50 I’m sure.
