Gran Turismo 6 continues the trend of incorrectly modelled transmissions, a problem the series seems to have picked up back in Gran Turismo 5. Such problems include cars with automatics or DSGs that shift jerkily (like manuals), E-manuals that respond to clutch input, or CVTs that can't hold the engine at a certain RPM. This is a list of all the cars with transmission problems.

and then there are the cars with wrong transmission ratios:

Megane RS
Focus ST
F40

Can you post GT6's gear ratios and what they should be? That would be awesome.

Cut out the middleman.

Fun fact, even the SL55, one of the few cars with a properly modelled automatic in GT5, acts like a manual in GT6.

Oh PD, how quirky you can get.
 
The new premium Mazda Demio has an incorrect CVT as well. I just used the SL55 the other day and it shifted like a true auto but i didn't do the stop and go test so not 100% sure.
Here's the list of cars with incorrect automatic transmissions. Let me know if I missed any car.

Mercedes:
SLR
C63
R129 SLs
CL600
CKL55
E55
SL65 and 600

Dodge:
Charger '11
Ram 1500

Chevrolet:
El Camino SS

Mario Andretti's Hudson

Both the Jay Leno cars. ( the tank car has a 4speed not a 6speed in the game)

Honda:
Element
Odyssey

Nissan:
Skyline Sedan 350GT

Mazda:
Atenza Sport 25Z
RX8 type E

Lexus:
both GS300s

Toyota:
Altezza AS200

Audi:
All RS6s

Citroen:
C5 V6 Exclusive
Xantia V6

Jaguar:
All the new XKs
XFR

Land Rover :
Evoque

Peugeot:
307 CC Premium

The 2013 GT500 Mustang gear ratios are wrong, they don't reflect the changes that were made to first and second gear for the new model.

I thought the F40 ratios were correct, is this new for GT6, different to GT5?
 
Tornado
They were wrong in GT5. Haven't checked them in GT6.

I think I can explain this one.

The F40 as modeled in GT5 & 6 is a curious hybrid. There were two different types of F40's built, or three if you count pre-production prototypes & the first 30 or so production models. The two main specs however were Euro-Spec and the USA-Spec cars. Gran Turismo describes the F40 as a '92 model and by 1992 all the cars being built (I believe) were the USA-Spec cars. They had a lot more weight then the Euro cars due to to things like a heavier exhaust with cats, exterior bumpers, and aluminium fuel cells. Ferrari never quoted any changes to power, but it is believed that the cats made them less powerful too. All of this led to a slower F40. Now I've never read anything to confirm this bit, but it seems that Ferrari attempted to compensate for this with lower gearing for the US models. Internet searching reveals the same, tall, 2.9 final ratio for both specs, but the gearbox ratios are lower than those used in the the first cars.

So where does this leave the Gran Turismo F40? It is listed as a '92 car and has a US-Spec '92 car curb weight. Power is listed as the same as early models (478PS). However, visually, it is a very early model Euro F40 with plexiglass windows that were dumped very early in the production run because customers did not like them. By 1992 no F40 came with them. Along with other light weight measures, these sliding plastic windows helped to make the earliest F40's very light at around 1100kgs dry, but they got heavier and heavier from there. You can get your GT car down to this early car weight with a Stage 3 weight reduction and plastic windows mod. The gear ratios? Supercars.net and many other sources list them as 2.77, 1.71, 1.23, 0.96, & 0.77, 1st through 5th, and these are the exact ratios you'll find used in the game. PD did not get this wrong, the ratios are the correct ones as used by European F40's, however if it is correct to say that by 1992 all cars were US Spec, then the ratios should be 3.69, 2.30, 1.64, 1.28, & 0.95 for a '92 car.

In summary, give this car it's weight reduction as described above, and you have a perfectly correct Euro-spec '87 model F40 with perfectly correct gear ratios, that is incorrectly described as a '92 model.
 
The R8 5.2 has an E-manual and not a DSG as listed.

Funny observation coming up, somewhat on topic.

A quick recap is that PD has 2 types of 'butter smooth' transmissions with both defined gears and 'creep':

- DCTs that are very quick shifting and throttle blip on downshifts and...

- Old fashioned automatics/CVTs with pre-defined ratios that could be slow shifting but definitely don't blip
(e.g. SL55 AMG and the ones that are fitted IRL on many others, even the SRT8s).


Now the curious issue is that there isn't the 'in-between' type that blips yet shifts noticeably less quickly than DCTs. This is the characteristic that the newer Jags, '08 RS6, CTS-V and IS-F should have.

The McLaren F1 is geared way too heavy (it is geared to do close to 500 km/h, 100 km/h too high).
The numbers match but something has gone wrong when implementing them. It was this way in GT5 as well.
IRL the car hit top speed when running into the 7500 rpm limiter in 6th gear doing 231mph/371kmh.

The new generation Ford Focus ST uses two different final drive ratios IRL, the set for 5th and 6th gears is missing and as a result the in game car has far to long 5th and 6th gears.
 
Few games I find get cars with automatic transmissions correctly and treats them all as manuals (in terms of how they shift regardless if you have the automatic shifting option on or off). I'm not sure if Forza even gets this right, I think a stock F-150 Raptor shifts like it was a traditional manual (on that note, I have a pet peeve with vehicles like the Raptor where part time 4WD is treated as full-time AWD that functions on drive pavement without issues).

I know Enthusia got automatics correct:

Someone posted once that the F1 has some sort of second final drive ratio in its gearbox in real life or something. Personally I can't really wrap my head around what that means, much less find any good reference to it or explanation on the web, but the claim is that this results in gearing that is almost impossible to model correctly in the game.

Perhaps a F1 fanatic out there could clarify?

The F40 issue is not so easily fixed, the closer I bring it to scrutiny, the closer you get to seeing that this car is just plain incorrect. Gotta bow my head and concede that Vegard & Tornado are right here, the car's all messed up. Check out the drag/aero thread, and view their videos, & see why not only are ratios screwed up, but the top speeds regardless of ratios are too. :(

The TVR T350C has incorrect gear ratios. In real life, it is capable of doing 175 mph, but in GT6, it can only go 155.

It was like that in GT5 as well, and GT4 IIRC.
It should be geared like the Tamora, Cerbera speed 6, and Tuscan speed 6.
 
Isn't the Chaparral 2J supposed to have a semi-automatic slushbox?
The torque converter was supposed to make up for the lack of a short first gear.
 
And the 2D in the game had a two speed rather than the 3 speed depicted. The 3 speed was installed when they upgraded the engine to the unit later used in the 2F.
