Anyone notice that a few of the cars have extremely long gears?

Eg:
Lexus IS-F: 7th and 8th gears are effectively for cruising, the car can't get any higher than 6th

Lexus LFA: Only two places where I can shift up into 6th are Mulsanne and SSR7

Corvette C5: 4th and 6th gears are quite long, but can shift all the way

Corvette C6: 5th and 6th gears are too long IMO, the car actually loses speed when you shift up into 6th

Any other cars like this?
 
Many American cars (all of the Vipers, all of the Corvettes made after 1990, etc.) are geared like this on purpose, because it helps with the fuel economy at highway speeds. You only get 5 gears for usable performance, and 6th gear is soley for turning the engine over at > 2000 RPM when driving at around 75 MPH.


In regards to the IS-F, the 8-speed transmission was designed purely for fuel economy purposes (basically, as you said, cruising), which is actually one of the things that early reviews for the car didn't like (the car would cruise in 7th or 8th gear, and would take too long kicking down when you stomped on it). This is generally the case with almost any automatic transmission, in fact (the top gear is purely for cruising and isn't really usable). It is just with the recent proliferation of 7-speed and 8-speed gearboxes, it is more typical for two gears to be used for fuel economy reasons rather than just one.
 
Yeah, the Nascars do. You really have to keep them above 6000 rpm if you want some grunt... Not surprising really, considering they spend all of their time near the redline...
 
The stock gearing on the Lotus Evora goes up to 292 mph... not sure if that's a bug or the way it really is irl but the car has no where near enough power even maxed out to turn the stock transmission up that high.

Appears the real car uses two different final gear ratios, one for gears 1-4, and another for 5&6, perhaps PD forgot to account for that.

The Chaparrals are the obvious ones really. 0-200mph in 2 shifts, it's like a jet fighter taking off!

Well, atleast the NASCARS come with adjustable trannys.

The Chapparal's have really LOOOOOOONG gears!

^This:tup:

I actually love taking the C5 Corvette out on the Mulsanne, just to hear the 6th gear kicking in, and the revs going straight from 7000rpm to 3000rpm:drool:

The Sebastian Vettel X2010 is also geared to 507km/h by default (non-adjustable). You can only reach that speed (and shift up into 7th) with low downforce (though the car still sticks to the road like superglue:sick:)

Another one is the Ferrari F40, it can go through the gears easily, but still seems to be quite long:confused:

Some aren't too bad though as Merecedes's 7G-Tronic gearbox (7spd auto) can kickdown more than one gear at a time effectively eliminating the problem. Not sure about the Lexus though.

Thank you for explaining that I always wondered why the Corvette had such long gearing. I always thought it was to achieve an unattainable top speed in stock form but once tuned it takes advantage of the long gearing. But what you said makes the most sense. How come I didn't think of that:grumpy:
 
Actually, the C6 Corvette Z06 and Zr1 are not long enough. They got it right with the Z06 in prologue, then screwed it up in GT5. Third in the Z06 should end at around 124 or 125, it ends at 118.

The Viper, 97-02 Firebird and Camaro all used the same T56 transmission, though the Viper's tailshaft and tailshaft housing were beefier. The gearing in these cars is quite long and using 6th will cause a loss in top speed.

The Corvettes are the same.
 
Also, the Honda Z act has stupidly long gearing -50mph in 1st and it has 30bhp-WTF. For a laugh someone pushed me up the Top Gear Runway in their X1 and even at 212 mph it had still not reached the redline in 4th(top)!!!

The Caterham Fireblade does around 80 in first and despite its brilliant power to weight ratio it takes over 8 seconds to get to 60mph!
 
the ACR Viper is geared, stock, to reach over 600kph, even when fully kitted out it reaches 6th......and loses speed even with 1000hp

They've made a cock up with the gearing on the Caterham. Being a bike engine it also has a primary reduction ratio of about 1.5:1 which means the clutch and input shaft into the gearbox rotates slower than the crank, unlike with regular car engines where the crank directly drives the clutch (and so gearbox).

All the ratios listed in GT5 are correct for the blade as is the final drive / diff ratio, but because they've not taken into account the primary reduction, it's geared for about 200mph rather than about 130mph which it should be. Slap a customisable box in there and whack it down to about 130mph tops and it will fly.

And my username does give away what I used to own, something very similar with the same engine but a bit cheaper to buy/build!

I bought the old Honda N360 for fun. Left it stock and took it online and had some nice hot laps with another guy driving a Daihatsu Midget. It was neck and neck around the Top Gear Test Track.

Anyways, this old thing has 4 gears. I can never get halfway through second gear and it pretty much tops out. Launching in 1st is terrible because it's geared so low. I mean, it takes you to roughly 50mph, in 1st gear! That's quite long for a car whose top speed is around 80mph?

I'm wondering if it's not a bug, considering the way we can't make custom gear ratios, I think gear ratios aren't 100% reliable game-wide. Also I can't remember which car, but it's stock gearbox was bugged. Everything would be fine until you shift from 4th to 5th, and the RPM's stay the same!
 
i think its the D2 chapparal i took it for the annoying classic car race (with 3rd stage turbo) from the start i lost the race it take ages to shift. i won the race later when i replaced the high range turbo for the medium range turbo and decrease the top speed to 250 km so the car can sheft properly
 
I think they're called overdrive gears. The gears you only use for driving on freeways and such for economical reasons. Most cars have their last gear like that. What I've noticed is that a lot of modern American cars are still pretty much 3-4 gear cars with one or two overdrive gears afterwards. The Ford GT, Viper, and Corvette are geared so that you usually will only need 4 gears.

Cars with wide powerbands (such as the big displacement V8s, V10, and supercharged motors of the three cars you mention) can run taller gears and benefit from having fewer gear changes necessary.

Something like a naturally aspirated four cylinder car can't handle that because it only makes power up high instead of almost any engine speed like big displacement motors.
 
Eric.

That reminded me, the R10 TDi has 5 gears IRL, whereas it has 6 in GT5.

Massive overlook:ouch:
