Scania v8 730hp

Thats the truth and there's alot more to a truck than engine, trans and rears.

 

On a second thought I think, that having engine or transmission builders capable of competing in a whole, huge market make them way stronger over time. I would rather have motor that is the best on the market at a time and match it with the best gearbox just available. Then have it all assembled into best truck of my choice by the manufacturer that provide the greatest workmanship. That is exactly the way i get to drive what I drive, no compromises were made.

The way you have in Europe is not even close to American level of competition - unless Scania is building best components all around, which we know it's not achievable, sure they may build best truck overall, but full of trade-offs. If Volvo I-Shift tranny is better, you getting hurt choosing Scania for its engine, right?

 

this part is true

generally scania build very durable components they are not trying to experiments with unknown things like other manufactures , for example scania differential for road vehicle is double larger than MAN diff.

also i have never heard anyone have differential brakedown ,drive shaft gearbox they are all strong

but in other ways scania is very unconfortable still most of scania trucks are with only 2airbags per axle , scania say that their customers like this way and they offer 4bags but still i know maybe 10trucks here with 4bags , most of customers love 2bags for stability especially in bulk and tank applications

related to gearboxes i-shift was for a long time best automated gearbox on market but now on last tests their made scania won over 3competitors although it is slow

 

Tests? How can you test gearbox for million miles? The only way is to wait long years watching its performance in the real world.

All your Euro trucking magazines & journalists are scumbags who take bribes from the makers to fool you into thinking they TESTED it. There is nothing like it here, truckers don't buy such BS in general so it's harder to make money doing "tests" for some crappy magazine.

Thats also why it takes decades to build reputation and years to loose it (think CAT)

 

that gearbox is well tried and tested scania use this platform for 20years in 2005 they release small redesign with different housing stronger rates and similar ......


but thing about better is related for controling of gearbox

before scania automated manual was not best solution

today scania offers best clutch control in industry gearbox shifts smother than before it is faster and smarter for gear-changes

also they have some good options for it and they are simple to use

( i mean on ECO mode Power mode, maneuvering mode, and rocking mode)

this was tested

it is hard to test gearbox itself because volvo and ZF gearboxes are pretty young

ZF is i think 11years and volvo/renault 9years


edit: also scania is very careful with new things they sometimes lag behind the other manufactures just to be sure that this thing works

today they are only manufacture that use same gearbox for manual and automated gearbox, reason is cheaper parts , no need to additional training for mechanics,..........

 

You're right about the V-8 vs. the I-8, but off a little on the other points. The I-6 is better balanced and thus smoother than a V-8, the advantage of the V-8 is the shorter crankshaft and more closely spaced power pulses which makes the torsional vibrations easier to handle. Also, a V-8 of equivalent displacement can have a much greater total valve area allowing for better breathing. The packaging benefits of the vee (easier to achieve equal length intake and exhaust on each cylinder,) are largely irrelevant on our forced induction diesels. The drawbacks are increased complexity (double the number of cams, heads, etc; ) with the costs inherent to that; and slightly higher frictional losses.

So in the automotive world, the V-8 sits in the sweet spot: it's far better balanced than a V-6, shorter than an I-6, and far less complex than a V-12 or H-12. It is a compact powerhouse! But the heavy duty truck world, with our much lower specific outputs and rpms, plus room to spare, the I-6 will continue to rule. The added cost of an equivalent V-8 all but ensures it.

 

all that worth above but

v8 is heavier than equivalent volume i-6

which is important for your market


but in some cases v8 could be longer than i-6

on scania on inline engines it is possible to install battery box below cab-behind engine with v8 no possible at all

v engines are usually harder to cool than inline and they have more components

but v8 have good construction for agresive jobs like heavy haulage and construction logging where you need to apply all power at once in starting ...


also v8 have some other benefits

like on winter fuel filter is inside engine and engine keeps it warm so even with bad fuel in extreme climate no problems with freezing fuel

 

Int Transtar ,Paystar , 9400,9670, 9800.
Peterbilt 352,362,379

The one's I am talking about where the int was better built then the Pete was the 362 vs the 9800.The Int also cost more.

The drive-lines were the same , just things like mountings ,brackets piping etc was better on the Int.

 

Scania build their components by giving a slight improvement on the last, I have still got my first scania , it's a 1984 142m with 4.2 million MILES on the clock, it's got a few alternators. Starters a compressor but apart from that it's totally genuine apart from springs and service parts, , I've had 32 in all and never had I had to tow one home due to a breakdown in 16 years of ownership, in fact scania are the only manufacturer in the world to still have half the trucks it ever made to be still running, it's a great fete considering the are making trucks since 1902, it's not uncommon to see 20 year old scanias doing heavy hard work here and are still highly sought after at that age ( check out A&M's website they got a 143 for 50,000 euro, about 75,000 dollars) they are tough and very strong and a massive hit with owner drivers here, I guarantee if any American had one for one week they would gain your respect despite the short cabs!I had cat engines in a foden and some cat machines I owned, great engine but seriously thirsty

 

I've had cat engines in a foden and a few cat excavators, great engine but seriously thirsty
