Forza II is by far superior to GT series. Only people who never tried it say that GT is better.

As far as NFS, it looks to me like they are trying to boost GTR franchise sales by slapping NSF tag on it. Look at screen shots. . . it's plain GTR.

NSF is nothing more than trademark these days, one year it's street racing, other it's cops game next year its simulation.

Original NFS started out as simulation racing game, PCs weren't as advanced as they are these days, but NFS was marketed as simulation, not acrade style racer.


Starting with NSF II though, franchise shifted toward arcade racing and never looked back, until now.

lol Ivan, get a little carried away?

And you guys are all wrong...iRacing or LFS are real simiulators, these console games are just that...games

Okay, how'bout a 4l FlexFuel V12 with DI, a quad-charger system, cylinder deactivation, and KERS, in a mid-engine carbon fibre-titanium composite chassis tub, and magnesium alloy wheels with slotted, drilled carbon-ceramic rotor, 10 piston caliper brakes?

now that sounds like fun :D :D :D :D

"DUDE wheer are you getting this 'inertia' thing from? The article doesn't even mention it..."

You have no idea pal!

Read the text: "After a dyno pull, instead of ceasing to record data, the machine records the slow-down period, and measures the drag due to the car's powertrain, including engine, transmission and wheels"

Did you comprehend any of that? That "drag" is is the SUBJECT the article is about and that actually refers to measuring drive train "inertia".

You should probably have a quick recap of some basic high school science and learn how to spell.

hahahha nice. tell a guy to get a primer on physics then equate drag to inertia. maybe you should take your own advice.

1) drag is aerodynamic, 2) friction is what is actually being referred to, but 'drag' is a colloquial way to say it, so that's excusable, 3) inertia refers to to the tendency of a body in motion to remain in motion, and relates to the force imparted upon a mass. friction (or 'drag' in the colloquial sense) works in OPPOSITION to inertia; inertia is assumed, and is determinate by the mass of the objects in motion and the forces imparted thereto. No need to measure on a dyno - once you know the RPM, you can calculate that with a scale and sheet of paper.

What is being measured is the friction (which is dependent upon any number of factors, including materials, surface condition, lubrication, surface area in contact), and can be relative to speed, force and other factors. Hence the measurements.

Every new GM product seems to have the same center stack, flanked by vertical air vents. I know changing the satnav and other buttons is expensive, but the center of almost every interior is becoming just a series of minor variations on the same theme. Same buttons, same vents, etc.

some people call that 'brand identity' or a common theme

there does seem to be a hint of something else in there, not sure it's Lexus though...maybe Lincoln MKS? That's weird to even think.

I'm not usually one to be blatant, but this sucks! Honda fans the world over will mourn.

And so they take one step closer to becoming Toyota...yaaaawnnnn.....:(

Commented On: Dyno tests confirm Nissan GT-R drivetrain loss, power ratings

Transmission 'inertia' has nothing to do with transmission inefficiency. Inertia is only relavant on an inetial dyno as opposed to a real dyno that measure steady state torque output. An inertial dyno can only calculate power by timing how long it takes to accelerate a 'known' mass, usually an acuratley calibrated flywheel. This is a peak power test and has nothing to do with constant torque output (ie horsepower is usually only ever 'calculated' by torque x rpm / 5252 = HP)

The largest factor of mechanical transmission loss is gear inefficiency. Every type of gear is rated at a % loss at the teeth face of between 10-30%. These losses are an engineering fact. Each gear in the transmission between the flywheel and the tires that power has to transmit through ad up to a total loss of closer to 30-40%.

DUDE wheer are you getting this 'inertia' thing from? The article doesn't even mention it...

And you can quote all the textbook theory you want, but this is about an actual test on equipment used to measure these things
