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?

 

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)

 

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.

 

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
