Thanks Stickshifter for your insight into the offroad market state side & for your clarification of what different segments of the US market will be looking for.

In earlier posts (seemingly knowledgeable experts on the relevant BMW engines) the issue of re tuning the B58 engine, was discussed and I recall a the view that this engine could be easily re-tuned to comfortably increase it's HP by 20% with no material impacts on maintenance & longevity - meaning around 350HP. I can't recall whether this keeps torque with the existing gearbox limits.

I wonder then if INEOS will provide as an option for the US offroading market; being a re-tuned B58, (say to 350HP), the 8HP76 gearbox and larger tires? If so, this would put the Grenadier mid-table in your above analysis and probably allay much of the issue you have highlighted with that segment of the US market.

With INEOS US, industry experts and potential customers providing feedback, one would think INEOS head office is/has/will to consider such "options" to maximise US selling opportunities.

Good grief, maybe you should read the post before sounding so sure of yourself: it was not the Ford diesel being referenced, and I clearly state that the vehicles are of a completely different class. Your comment comes across as under-informed, and a little rude. Lastly, I didn't ask for this topic to be revived, but I'm annoyed enough by your post to engage (though its probably not worthwhile).

Here is the post that you commented on - it is Post #15 in the thread Interesting Marketing Approach. I've changed the font color of the section you commented on, and put it in bold, to help you locate the relevant information:

START OF POST ---------------------------------------------

Yes, of course you are correct: no one is forced to purchase a Grenadier, and Ineos must operate as a for-profit business. But read the comments in response to Grenadier videos on YouTube, and most Americans are expressing similar concerns to those I have expressed here. I think most Americans who have followed the development of the Grenadier have a lot of respect for what Sir Jim is attempting, and we are excited that a vehicle we have long-wanted is finally coming to our shores. American 4x4 enthusiasts have long-bemoaned the departure of the old Defender in 1997, and the 70-series Landcruiser in 1987. Those who have followed the Grenadier closely, also understand that it was Sir Jim's goal to build a vehicle for global overland travel, where the key requirements are durability, payload, and traction on rough roads and/or moderate tracks. There is absolutely nothing wrong with these goals, and - in fact - this is what the majority of overlanders want (whether they are European, Australian, or American). However, there is some divergence in use-requirements between the “global market” (Europe and Australia), and the American market. These are my observations:

Summary: Americans who have followed the development of the Grenadier understand that the vehicle is intended for overlanding. We don’t think that there is anything wrong with that, but we are really trying to figure out if it will also be suitable for some of the things we may value that the global overland community does not, such as those I mentioned above: adequate power for highway driving at elevation, and adaptability to technical terrain. With respect to these two criteria, these are the concerns that I and many other Americans have expressed:

(1) The Grenadier does not have a great power-to-weight ratio; the gas-powered Grenadier is almost as heavy as the gas-powered (7.3 liter, single rear wheel, 4x4, regular cab) Ford F250 SuperDuty – which is a gigantic truck – but the Grenadier makes just 65% of the HP, and 69% of the torque that the big Ford makes. And while the vehicles are close in weight, the 7.3 Ford has a payload of 3,500 pounds (nearly double that of the Grenadier) and can tow 28,000 pounds (almost 4 times that of the Grenadier). On the surface, there seems to be no reason to ever compare the two vehicles, until you look at the fact that they are nearly the same weight. Lastly, there isn’t much room for tuning the B58, since the ZF transmission paired with the gas engine is the 8HP51, which has a max torque capacity of 369 lb. ft.

(2) There isn’t an “off-road” package from the manufacturer (larger tires & re-geared axles) and we don’t know yet how easy it will be to modify the Grenadier on our own (lots of technical discussions of this elsewhere).

If the gas engine came with the 8HP76 (as does the diesel), and if there were an “off-road” package from Ineos, I think many Americans would feel like the American market was important to Ineos. I’ve become frustrated at waiting to see if the Grenadier can be what I want it to be, and I recognize that this is my problem, not anyone else’s. At this point, I just want to know if
I am best served taking my business elsewhere, or if I should continue to wait.

This is the last time I’ll post on these topics, as I am sure it is tedious for members of the forum. My apologies for beating a dead horse. Time to move along.

END OF POST -------------------------------------------------

As to the topic at hand - "Is the Grenadier under powered?" - we are all free to hold whatever opinion we choose, but the conversation is not so absurd that it should be ridiculed. For example, about six months ago I posted the chart below - which was data I happened to have in an Excel spreadsheet; it was my own personal research on a handful of vehicles that I have either owned, or that I considered buying. This was never meant to be a comprehensive list of vehicles, but you will notice some that are more relevant as a comparison than the Ford SuperDuty, a comparison which has clearly got you bothered. The Grenadier came last in both these tables (power-to-weight ratio, and torque-to-weight ratio). So I thought it a topic worth discussing.

Yes, these are max power and max torque figures, and do not capture information provided by a dyno test, which would show at what RPM the power and torque are made. Its not my full time job to research that info - I was providing the info that I had. That's what people tend to do on a forum. I noted this when I posted it, and said quite clearly that the Grenadier - because it has a forced induction engine - will make much better power at low RPMs than the naturally aspirated V6 engines in this list - and as a consequence, it will drive much better than an engine that needs to be revved high to make power.

Frankly, I'm a bit baffled by unwillingness to consider other perspectives. Cordial disagreement is part of participating in a forum.

Folks can do with information what they want, but I'm not interested in talking about it anymore. As I said at the end of the post that has since been revived: Time to move along.
From the cheap seats: sharing your thoughts on the topic @stickshifter is much appreciated.

The question that occurs to me is What (design engineering) tradeoffs explain the difference? eg what’s being sacrificed in the SuperDuty (/other vehicles) to achieve lightness and/or what is being ‘earned’ in the Grenadier to explain the weight? Does it return the expense in the form of durability or reliability?

I trust that the Gren will take a beating in remote locations (I’m thinking corrugations/4-season use etc moreso than technical trails) but it seems it’s the ‘Grenadier Vanguard’ that will need to return those findings. This might hinge on the durability of internal finishes etc that might contribute to weight but less obviously to performance.

The other (power) side of the equation is slightly easier to account for given the “global overland travel” use case.

Anyway, very interesting as we rarely see vehicles like the Ford in Oz (or indeed the sizable US-style caravans/camper trailers they might often tow) - it’s remarkable how different EU vs OZ vs US RV parks/campgrounds/mobile lifestyles are and the suitability of different vehicles is self-evident.

B58 can certainly be tuned - there are some examples of BMW vehicles floating around with such a tune up. It will also require someone who knows what their doing. No point having 230kw and slurping 17L/100k on open highway. Warranty? Probably void the second you touch a BMW train.

On the test drive, I pushed the Gren on a flat run of bitumen and it was quick for 2.7T machine. Felt like more punch than my mates new Prado at full tilt, and it's what... 400kg lighter.

Think of those tiny little gears spinning like crazy. :eek:

Will be interesting to read the manual and see what is says about stuff like that.
My work car is a Merc diesel with an 8 speed auto, once its in the torque band it moves like mad, and its only a 2.1lt

There is absolutely nothing wrong with these goals, and - in fact - this is what the majority of overlanders want (whether they are European, Australian, or American). However, there is some divergence in use-requirements between the “global market” (Europe and Australia), and the American market. These are my observations:

Most people in Europe and Australia who are shopping for a rugged 4x4 vehicle, are interested in overlanding - which I will define as adventure travel by vehicle, in which durability, payload, and traction are the key criteria.

A lot of people in America who are shopping for a rugged 4x4 vehicle, want the same thing that Europeans & Australians want (a durable vehicle, with good payload, and good traction).

(1) Here is where I see the first diversion between the global market and the American market: Americans seem to have different ideas about what level of power is appropriate for an overland vehicle. I think this is particularly true in the Mountain West, where our highways run over high passes, speed limits range from 65 to 85 mph, there are a lot of freight trucks on the road, and an under-powered vehicle feels unsafe (or just tedious).

(2) A second diversion between the global market and American market is that many Americans go "sport off-roading" (for want of a better term). By this I mean driving really hard trails just to see if they can. They build up their off-road rigs with 35, 37, or 40-inch tires, and test their vehicles and driving skill on very technical terrain. I think a lot of "overlanders" look down on "off-roading" because it involves using a vehicle for sport, and this is seen as a waste of natural resources, and as a source of unnecessary air, noise, or water pollution. In contrast, "overlanders" use a vehicle to travel to somewhere beautiful, or remote, or to access the back-country for recreation (climbing, hiking, camping, skiing, hunting, fishing, etc.). Overlanders often regard their use as more ethical than off-roading. Under careful scrutiny, I'm not sure if the distinction holds up, but I understand the argument.

(3) There is also cross-over between the overland and off-road community in America. This is especially true where trails to access recreation are technical. As the Mountain West has gotten more crowded, more and more people are using vehicles to travel hard technical trails in the hope of finding some solitude. This may be related to another difference in culture: I think that many Europeans are used to their mountains being crowded, while Americans are not. I have climbed extensively in the French, Swiss, and Julian Alps, and the climbing routes are packed; wild camping is often forbidden, and the mountain huts are booked solid. Many Americans in the Mountain West have an expectation of solitude when they head out into the mountains, but this has been changing quickly. Many of us are trying to cope by driving deeper into the back-country before starting our recreation. For example, I never go “off-roading”, but I have run 35-inch tires on multiple vehicles in order to access remote trails for climbing, camping, hunting, etc.

Summary: Americans who have followed the development of the Grenadier understand that the vehicle is intended for overlanding. We don’t think that there is anything wrong with that, but we are really trying to figure out if it will also be suitable for some of the things we may value that the global overland community does not, such as those I mentioned above: adequate power for highway driving at elevation, and adaptability to technical terrain.

The table you provided is a much more relevant discussion point, I stand by my comment that the Super Duty in any format is not a relevant comparison l’m sorry you don’t like that. No one is trying to shut you down this is what disagreement looks like.

A comparable type vehicle could be a new Y62, LC300, New Prado, Toureg if you want, New 70 series etc. This range of vehicles is the comparison point and really, the Gren stands up and above this crowd at first pass simply on its parts list alone.

An amazing thought, Ineos and Magna have already worked it out but the promise is longevity and warranties to suit…I personally don’t think Ineos are going to promote something that is going to change the philosophy that has created the vehicle in the first place…built on purpose…typical of most vehicles you wait till warranty time runs out before you screw with it…then…built for your purpose

Maybe not a direct comparison, the uses cases are totally different. But interesting to think about nonetheless.

Their weights are similar and didnt Ineos bill itself initially as a one ton tuck with a half ton body. Why not compare it against a one ton truck?

I think there is no general answer to the threads question.

The title should rather be "Is the IG underpowered for your purposes?"
