Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.
Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!
I got a new car, Infinit G35, I love it, yadda yadda yadda. It is normally automatic transmission, and I really don't know anything about driving a manual. However, it has the option to kick itself into manual transmission. As it's not built from the ground up as manual (it's a 5-speed), I don't really know what would be better to do. I'm pretty sure the manual has a lot of gizmos to keep me from fucking up too badly, but I want to know three things:
Which mode would be better for gas mileage?
Which mode would be better for general driving (2/3 highway, 1/3 city, probably other way around starting this fall)?
What should I know about manual transmission on an automatic transmission like this (since there is no clutch)?
I really don't know much about manual in general, so basic stuff, like when to shift up and when to shift down is appreciated, but deciding between the two modes is more crucial. Some people have been telling me that automatic is in some cases better for mileage than manual, but I feel like I should doubt that.
as for gas mileage b/c its not really a manual, ie no clutch, the gas mileage shouldn't vary significantly if you do use the manual feature. How hard you press on the gas is gonna be the bigger determinant.
As for shifting, when you are accelerating shift up, you can get a feel for it just by driving the car. the longer you delay in shifting up the faster you can accelerate, but when you hear the engine starting to rev high, as in a lot of RPMs, then shift up. When you slow down its helpful to shift down to help slow the car and go easier on your brakes, if you slow down and then press the gas and the engine sounds like it is sputtering and running slowly, you need to shift into a lower gear then the one you are in.
Play around with it and get a feel for it. My moms car has the option to do the same thing and the car won't let you shift into a gear that would be damaging to your car.
I wouldn't say one mode is better then the other for general driving. If it is just a commute I would leave it in automatic, if you are going on a windy road with lots of curves, and want to have some fun go manual.
Um actaully, from a roll, say you're cruising at 35 in 4th gear and you really want to accelerate, you shift down. At least that's what you do in a regular manual.
Btw way, enjoy the car, I just got back from a 6 hour drive in my g35 and it was nothing but spectacular the entire time.
Sedan, since its my only car. It's all sorts of ballin'.
So basically its going to give the same gas mileage, but give me better control over the speed?
What I can't really wrap my head around is how pushing the car through higher RPMs when accelerating can be better for gas mileage. Isn't RPM really the only thing that'll tell you how much mileage you're getting?
So what you really have is an automatic transmission that lets you pop it into a mode where you can knock it up or down a gear at will. That's not really going to help too much fuel- economy- wise, but it's great for when you need to pass somebody in a hurry.
It will probably get better mileage shifting on it's own.
This space eventually to be filled with excitement
This is most useful, as said, when you need to accelerate quickly, you can pop it into a lower gear to get more power. Also if you're going down a long hill you can pop it into a lower gear and engine brake to save your brakes.
2) You need to go from cruising to hard acceleration
3) You are cornering and want to keep in the meat of the torque band.
Other than that, feeling badass is the only additional feature. I got the manual on my GTO, even though the auto is faster 0-60, almost entirely because a manual transmission is a more engaging driving experience.
I would have very seriously looked at the the G35 coupe if it came in AWD/M6. Its damned beautiful, and the new G37 even more so.
Congrats on the new ride. It's a solid, mean driving machine... *ahem*
You'll definitely find the transition from auto to click-shift strange and weird. You're not going to actually be gaining anything in MPG over the auto until you've gotten a good idea of how to maximize a MT without screwing over your box.
The basic idea of getting good MPG with a manual is being able to drive like a grandma. I keep my rips between 1.5-2 most of the time for better mpg, but this means that you're giving a fraction of the power to the wheels that you could be, which can be dangerous if you're not used to knowing exactly what gear to get into if you need to quickly zip ahead and avoid trouble.
The other issue is that the box in these click-shifts is sequential, which means that in order to go from 4th to 2nd requires a good bit more time than in a real MT. It also isn't that great on your gearbox and engine.
Keep that click-shift for what it's meant for. Pickin' up teh mad honeys outside the corner store.
I'm so used to having an MT with a clutch, I don't know if I could ever drive one without one(or an automatic) again.
Yeah, I ride a motorcycle, and have a manual when I drive my own car, but I've had to drive a non-manual a few times recently... it's really really awkward. I kept on hitting the footrest thing where the clutch should be and throwing a water bottle in the center console around.
The worst is when you slam on the brake because you expect the clutch to be there.
Some already mentioned this, but when cornering, downshift. In auto, you wont downshift and you'll lose power and acceleration.
And fuck the G37, I think it looks like ass compared to the G35. Also, I'm a little jealous that you can now get an altima coupe with basically the same styling as my G35 coupe, but with less power. Although I wouldn't sacrifice the power, a touch screen nav and bluetooth capabillity is really nice.
My nav is awkward to work, the buttons are too sensitive.
I can't imagine the number of accidents I've almost caused by trying to disengage in borrowed autos... One of the reasons why I try to just flat out refuse these days.

A lot less power, handling, torque, and performance. Even the Nismo Altima (performance) is rat feces compared to my lx Civic. Compared to the G35 it's a molecule of kitty litter. hah.
If it is an 07, I'm pretty sure it has a CVT so you should use atuo unless you want to have fun. You aren't going to get better gas milage using the manual function because it just used pre-set ratios and not real gears.

Use pseudo-stick for 3 reasons:
1) You want to smoke the tires
2) You need to go from cruising to hard acceleration
3) You are cornering and want to keep in the meat of the torque band.

Welcome to the world on this side.
You should really give it a shot sometime-- it makes you feel a rally driver. And it's wicked fun if you're ripping a bunch of torque, like in a G35.
