Nps vs fg

G'day John, I was actually talking about the passenger seating eye level. In one of our 6 wheelers, the eye line of sight is right in line with the bar across the top of the windscreen. It was a bit of a failure on my behalf, as now the foward vision of 6 passengers is severly comprimised.

Sorry mate. I was off on another tangent then. Eye level is OK through the sock on the new FG . IIRC It's virtually the same as the old model anyway. I'll see if I can get some inside pics looking forward from the seats to compare the new and old models. Adventure Tours are about to get their second new FG, so I'll take some pics from both models. This pic doesn't really compare the cab height's (between new and old) properly cause of the angle it was shot at. That's the second new cab chassis behind getting ready to come up to us.

They also stated this Power comparo between the FG and the NPS.( The spec sheet states that the Mitsubishi has 52Nm extra torque. However this is only available at 1600rpm. Because of our variable Geometry Turbocharger, our 419Nm of torque is available for over 50% of the rev range. If you look at the vehicle travelling at 100kph, and both vehicles hit a slope, the Mitsubishi has roughly 390Nm avaiailable, whereas the Isuzu is still at maximum torque of 419Nm. = More usable power per gear without having to down shift).

How do they Feel in real life John,are they similar?

John, while I haven't read this before nor analyzed the different torque curves up close, I'd say this is exactly what it feels like.

A bit like riding an old 2 stroke motorcrosser. They just feel fast but the lap times aren't close to a modern 4 stroke. Hop in a new FG with a bare chassis and you feel like your in a sports car. Especially with the short shifter on the dash. So much fun it can't be legal.

Hop in a NPS and it seems much less punch. Still strong but less responsive. That's how they feel anyway, but in reality they are about the same performance empty. Bring them up to max GVM (6ton) or more (6.6ton) and it's a different story. You asked "how do they feel?" >>> well after probably 40 runs up the dragstrip in the new NPS and more than twice as many in the new FG's I can say that at the 400m mark, the NPS is at least 15kph quicker. We actually recorded acceleration as well as deccel but as it was only brake performance we were concerned with when we did this testing, I don't think the engineer has kept those numbers.

The figures are like a long inertia curve from start to stop and the at the point you touch the brake pedal, the distance is recorded. So the the entry speed in Kph, deccel expressed in g's and the stopping distance in metres is all that's kept on an overlayed graph.

You might be thinking "Who cares how a truck performs on a dragstrip?". Well what is important is exactly as is stated in the Isuzu blurb about hitting a hill at 100kph and whether you bog down or not. Bog down and your fuel consumption increases. Vary the turbo to compensate and you can reduce this greatly. Also I hate being a moving road block, especially out on the 100kph country roads.

NTSQ this would be a good opportunity for you to jump in on this. Variable Turbo Technology is your thing isn't it?

So for a fully laiden expedition truck the NPS will handle things better. If your light (say 4.5 ton) the difference isn't as noticeable. It is the same for the brakes and suspension too.

Hey I know I might be sounding bias here. Not my intention. So as we go on with this thread just bear in mind that the NPS is more truck but it's also more money too and many of the features where the NPS is better may not be of concern anyway when you convert your truck into a motorhome. Just remember this.

As an example, the rear springs on the NPS will easily handle beyond the max GVM. Only just hitting the over rider springs at 6 ton. The FG's won't. After running around at max GVM for a week or so they are really flat and maxed out. Build an expedition truck where you have a comparatively constant rear axle weight (whatever that maybe) and the optimum is having a set of springs made to suit so that you you have a smoother action as opposed to sitting on the over riders all the time. So it really doesn't matter if you intend to change them over anyway..

Regards John.

Hey, I just wanted to throw these pics in somewhere. These where taken driving the NPS through Brisvegas on the way to Willowbank Raceway during the worst dust storm for the area in the last 70 years. This is the sort of event you get in central Oz. Not South East Queensland. Any excuse to throw in H3 and Bushmaster pics, heh? ....Lol.

Not to mention how handy a fatter torque curve is in sand or tight steep and loose tracks, etc.

Thanks John,that info on the Performance Testing really helps me in deciding which vehicle to chose,the info I have posted came directly from Isuzu,I know there is a difference in cost between the two vehicles (in my case $6400,00 with the Media Player upgrade) but the Torque difference is fairly substantial between the two at cruising speeds.

John . Their is alot you can do to an FG to improve the torque but it all costs. I think we covered Taipans exhaust didn't we? Did you know that the new FG with the bigger multi valve engine still has exactly the same exhaust as the older 649 model? No change at all. Huh? Heaps of potential as we've already found out.

$64k with audio upgrade. Imagine you mean Nav card and a reverse camera. Is that right?????

I spoke to the guys at our local car audio the other day about these units. There comment was that "If units like this are coming out standard they'll be out of a job very soon". They are that good. We just did an awesome audio upgrade for one of the Expo member in his FG recently but the Isuzu unit isn't that far behind it. And it comes standard. One of our guys at work is a legend with In Car Entertainment. (BTW They call it ICE now). Ian. He's been doing a lot of research on the new Isuzu units to see exactly what can be done on top of what Isuzu offer.

All the inputs and outputs are there. SD card, Aux in, USB, Bluetooth, 3 x camera inputs, amplifier out, blah, blah. My only complaint after using the touch screen when dialing phone numbers was I couldn't keep my finger still enough with the bouncy suspension.

The Isuzu reverse cams are very compact too and the split screen function is very cool. Any combination of camera inputs can be selected by one touch and camera is prioritized in reverse gear. If you are towing alot I'd consider 2 cameras. One high and one looking at the tow ball hooked to reverse gear. We've done this before. Makes hooking on the trailer a cinch.

Yep I allready do that on the Iveco Campers,people look in amazement when I can back up to the boat spot on with the Camper on. :ylsmoke:

Traction Aids for Diff(s)?

I've been tracking along that a rear locker will (might?) soon be available for the Fuso FG..... What traction aids are available for the Isuzu NPS 300? Lockers &/or Limited Slip Diff (LSD) for front & rear axles?

Thanks.... Curious once again

KEENO:)

Hey Keeno, The NPS 's all come with a very tight rear LSD. The FG's (here anyway and I think in the US is the same) have a really good rear LSD as well but there is also a locker available in Oz as a dealer fitted option for the 649 and 84 that is similar to a Detroit locker. Rumours are around of an airlocker but then they have been for years. Here's hoping anyway.

I couldn't believe how many neat trucks I saw on the drive here yesterday, once I got on the Pan American Highway. Lots of Fusos, they are the most common here, but also quite a few Isuzus NPRs (mostly with the Chevy badge) and a bunch of Hino 500s. I'm in the big city (Arequipa) for a few days so took advantage of that fact and went to look at trucks today. First I went to the Isuzu dealer. They still had one big truck (semi) with the Chevy badge, but all the new ones now are Isuzu badged. They had a Reward 500, for $32,000, which seems to be the standard NPR, with a 150 inch wheelbase, 2 WD, and alongside of that a Reward 400 DT (both had NPR on the side as well), for $39,000, which is a 4x4, it was a 132.5 inch WB. As they don't have a drop frame like the Fuso, the top of the frame on that was about 37.5 inches from the ground, vs 31.5 on the 2 WD. It was a very nice looking truck :drool:, even though I plan on getting a 2 WD, I wish they were available in the U.S.

Next I went to the Mitsubishi dealer, they had 2 Fusos there, the only difference being the wheelbase, which I didn't check. Both were 2 WD so I asked the salesman about 4x4 and he said they don't sell them in Peru. Not sure if that is correct or not, as it seems strange they would sell them in the U.S. and not here. Didn't think of asking any prices there.

The Hino dealer has moved, not sure where they are at so didn't get to see them, but the 500 looked pretty nice as I met them on the highway. :smiley_drive:

OK, back to reality and looking for used stuff on the internet!
