Guys move on!!
Some leading manufacturers even come out with 7speed squential manuals... 6 speed is MUST for high performance car!! I mean MUST!! no exceptions!!
5 speed is just old fashion or for cars like honda civics, toyota corollas, and etc.
Sooner or later 5speed will be gone and all the high performance cars will have 6 speed or even 7speed smg!! may be we are already there... The only reason mitsubishi used 5 speed on evo was to cut down the price. Im telling you guys...6 speed is not a new tech... 5 speed is the past, 6 speed is now, and 7 speed smg is the future!!
I even have 5speed cars but I have to admit 6 speed is a new standard....

 

That is because they use completely different transmissions designed with beefier gears from the ground up. You pay for what you get. Plus the 6 speed helps keep the car's engine in the power band ..... closer ratio gears usually help with quicker acceleration upto a certain point.

 

I have to disagree with you. If the HP of a car is high enough, with gears that have a farther ratio, you can out accelerate cars with the same HP but closer ratios. The reason being the time lost in shifts .... gearing ratios and HP play a role when engineers try to design cars, they have to play a balancing game ..... saying 6 and 7 speed is the future is not true ....

 

I disagree as well. It just depends on the car. When its a big American car, the sixth gear is more or less just a super overdrive so they can get a certain fuel mileage rating. That cuts down on gas guzzler tax and helps the overall CAFE rating for the entire model range. Chevy has done a good job with the LS2 in the new vette as it provides 400hp and 28mpg on the highway, but the sixth gear in it (haven't driven one yet), the Viper, the F-bodies and Cobra are just for that purpose - not keeping the car in its powerband - not for fun.

Now, when your talking about more mass market sport compacts like the RSX Type S, Celica GTS - I can see how the close ratio box makes the difference. It isn't necessary on a SRT-4 because of the awesome toque and broad powerband of its turbo 2.4.

And just because the germans are putting 7 speed autos on $80,000+ sedans doesn't mean we all should have them. Perhaps CVT's are in our future, or 1:1 direct drive with infinitely variable valve timing, compression and displacement or hovercrafts - who knows.

As far as a durbaility aspect goes, all of the high end cars with these 6 speed MANUAL boxes are usually from someone else ie (Borg Warner, Getrag, Tremec, etc.) I'm thinking Mitsu built the Evo's gearbox themselves instead of outsourcing it (like the did from Getrag on the 3000GT VR-4) so maybe it has the same tough engineering in it from the five speed. We'll see.

 

first of all.. the 5 speed u tried coulda been broken in and the MR still new.... but yes 5 speeds are known to be more durable... while 6 speed's are faster on a road race because they drop u right in the torque curve better

 

Transmissions/torque converters are only needed for internal combustion engines. In the future we are going to see more and more electric engines with absolutely flat torque curve from 0 rpm all the way to "redline". More current - more rpm, constant torque, like a tram

 

Not true, the idea of gearing/transmission can also be applies to the electric engines ..... because if what you are saying is true, given the fact that electric engine usually produce less power than gasoline ones. One of there 2 things would happen:
1. Car would accelerate fine but would have a rediculously low top speed.
2. Car would have a decent top speed but accelerate like a pig.
Yes in the second case things can be done to improve matters, eg: lighter and smaller car ....
To have a decent acceleration downlow and a decent top speed you need a "transmission" ....

Where go you guys get this from????

 

buddy,
check the gear ratios on both gsr's 5spd and mr's 6spd, then you will see gear ratios on mr's 6 spd are not much closer than gsr's 5spd... only difference is top gears, which will give mr more USEFUL power band at the top end....

You will see who is right in a few years, mean while enjoy your 5spd until they are still available...

 

I wonder why the BOSS Mustang uses only three gears and not 7 ^

 

I just posted that earlier in the thread, you are regurgitating the same thing I said earlier.
What I said in the post you replied to applies to every car out there ....
It is true that we don't know which one is stronger, but an educated guess is all we can make ...

 

6 speed boxes serve a few purposes. In expensive German and Italian sports cars it helps them accelerate quickly and still reach the 180+ MPH mark that exotic cars are measured by. Here in the US, they are used to get better fuel economy ratings and avoid gas guzzler taxes. Look at a Pontiac GTO, the 4 speed auto is standard and is subject to a $1000 gas guzzler tax. Get the optional Tremec 6 speed and the tax goes away making it an almost free option.

One of the big reasons I bought the Evo instead of the STi was that the STi had a 6 speed trans. When I went for a test ride in the Suby, I noticed right away how often I had to shift. Having a light to light highway commute made that the more annoying car to drive everyday. I guess some people right away believe that more is better. It's better for economy, but for performance, adding a shift to stay in the torque band means someone just has to learn to drive better so they go into the corner faster.

 

ditto...that's why 272 hp evo is quicker to 60 than 300 hp STi.

 

must?

I'm thinking you're talking about the hydralic sequential F-1 style Shifter from new BMW M5? The 7 speed sequential manual is like tiptronics and you really can't compare that with manuals that we have on our car.

The BMW need that because it's pointless to have a 5 speed on a car that could go over 200 mph on that V-10 (500 + hp)

you'll be nut to put a 7 speed sequential on a hyndai with 4 banger SOHC.

it's really depends on the car.

I like 5 speed better, but 6 speed should of came with this car... whatever...

hmmm no, wrong interpretation on your behalf. I dry shifted both cars at the auto show.

1 of the 2 i test drove was one with 8900 miles. the other one was a new unit from the dealer lot with less than 40 on the odometer. both shifted exactly the same (as far as I perceived it).
