Can anyone help me out? I just bought the dodge challenger and in the dealership it listed its max horsepower as 425. When I go to look at it in my garage it now says its max horsepower is 412! What is going on? I haven't done a thing to it, I just bought it a second ago! Anyone know why this is happening?
 
My guess is it could be something like when a manufacturer gives out a cars top speed or power rating etc isnt always the true figure only a guess though

E.g Jaguar XJ220, Manufacturer speed 220mph, Actual speed 217mph :)
 
I remember in GT3 (I believe) when you first got a car your horsepower would increase if you changed the oil.

It is also my understanding that for the first few hundred miles run on a cars engine one should baby it in order to "Break it in" though I don't know how much of that is myth and how much is truth. If it is the truth, then perhaps horsepower increases as the engines are "broken in".
 
This is a hallmark of GT games, I'm afraid. The "advertised" (dealership) power should be ignored - I guess all the top-end, pre-2006 Japanese cars will be 276hp?

I'd hoped they would have stopped doing this.
 
So you bought a lemon. Did you ask to see if it's oil was changed regularly? You could try returning it for a refund. You did keep the receipt right? Rebuilding the engine is expensive.:lol:

Also, new cars sometimes need to be broken in. Try putting some miles on it, if it's new.

well i put 12km into it and now its at 413 horsepower so maybe it does need to be broken in.

Yes it will, but that's not the reason for the dealership power being higher than the garage power. Dealership power represents real world manufacturer claims, garage power represents real world power. Like I said before, it's a hallmark of GT games that I'd hoped they'd grown out of - especially as the "Museum" section allow them to publish the claims and the reality, while the actual game part can tell us exactly what it is we're about to buy...

So would I.

But alas, PD seems incapable of bringing this under a uniform standard.

The HP on all U.S. cars since 1971-72 is supposed to be rated at net, or rear wheel HP. However as the car companies have always done, they take liberties with the numbers at times, particularly it seems with the resurgence of the "pony" cars.

My guess is 425 is actually gross or crankshaft off the engine HP.

Hey its no big deal, just use one or the other.
 
Japanese Manufacturers always quoted 276bhp due to some law about power outputs. In reallity when actual cars were tested they usually showed considerably more than this. So in essence this "anomoly" is actually very accurate to real life.

Gentleman's Agreement - never enacted as a law. And we know - but there is a time and place for this information. Now there is the Museum in GT5, that's the place for it. People want to know what car they're buying in order to drive it in the driving game, not be given a figure they can't trust because of archaic real world politics...

I'd say the difference between gross and net HP on a RWD car with an auto gearbox is at least 20%. With the torque converter locked, 15%.
Probably the 425hp is just a marketing flag, as there is no way you could feel the 13hp loss when you never touched the car with the full 425hp in.
 
Yup typically you would buy a Skyline with a supposed 276Bhp, but when you viewed it in the garage it would have over 300, which is nice.
 
You say you bought it in the used dealership, probably they give you the stock hp but what about the mileage? In GT Auto you can get a engine overhaul which says it gives you back all power, have you tried this? If it helps I think it's pretty realistic, that old cars don't have their stock power!

/Edit: ok, sorry you did not saiy it's from the used dealership...
