Getting ready to Graduate High School....

[Rosie25]

Hello to all, this is my first post on Ls1.com.....anyways.... I'm just a junior but as a gift i get a car for college( i have to pay insurance and gas)... I have always wanted an F-body... But with gas prices as high as they are my father isn't too sure about the trans am anymore. He says there is no way that a 5.7 V8 pushing over 300 hp( referring to the trans am Ls1) can get over 25 mpg.. he says if it gets over 25 then he will be fine with it. Also on a side note, i have always wanted the Manual 6-speed, not only because of the performance gains, but increased economy... Does the A4 make mileage considerably close to the M6? I know to have an A4 for performance you need a stall but yea... is there any difference in performance?

Thanks for the help

[Rosie25]

nobody?

Get what you want. It you want a 6M go for it. It will get better mileage. It you want the A4 get the auto. Get what you want or you will not be happy! I have a 6M formula and love it! Take care of what ever you get and work hard in school. School is more important. Don't be a "show off" in an
LS1 or it will get you!:true:

[cant.b.caught.z28]

I would get the 6 speed, I always regret getting the A4..

[Rosie25]

Now that is a True statement..... I love driving standard cars, but not so much trucks...don't know why... I will get the M6... but the point on the pencil is, does a 5.7 LS1 really get 28-29 advertised mileage?? I am just a young driver, but i know my limits, and dont plan to "hotrod"... at least not in public:burnout:

Definatley get the 6-speed LS1, you may only get 18-21 mpg in the city, but I have heard of many people getting high 20's on the highway especially with an M6. The 3.8 V6 will not get alot better fuel economy. You gotta think, over 100 extra hp with the LS1 versus getting a couple of extra mpg in the V6. That would be an easy decision for me, get the LS1!

O the 3.8 is not even an option! i cant stand going by a perfect looking, clean trans am... and then all of a sudden when they get on the gas... you hear the Weak sound of the V6 ... on this forum some claim that the V8 gets better economy then the V6... but if that were true, why would anyone get a V6????

[joejenkinsglass]

I have both a4 and a 6m they both have +'s and -'s some people get 30+ mpg (they say) my almost stock ss 6m gets about 23mpg while the 98 turbo a-4 got about 18 before the stock bottom end broke don't know what it will get now?

[1 RedHot TransAm]

I own an m6 LT1 formula and a A4 LS1 my LS1's best run is a 13.3 with only a catback and lid A4 is still fast in its own right, but i'll admit the manuel is more fun to drive IMO...LS1's do get good gas milage, you just can't have a led foot which can be hard at times driving one of these baby's LoL

23 mpg highway.. are you running stock gears...?

[SpecterGT260]

I got 26 with long tube headers on my trip to nashville last year.

26 isnt 2 bad...

[SpecterGT260]

that was averaging 80mph on the highway. if u keep it to the speed limit ull see the 28 pretty easy in a 6 speed. the car is basically at idle at 60 in 6th

[JoshieDoom]

25.5 on the highway in my a4. Thats the best ive ever got. but.. ive got a lot of worn crap.. after 14X,XXX miles.. at the time.

[rapter34]

I get about 26 on the highway with a M6. I'd like to say that I get in the 20's in the city but i love the loud peddle just a little too much. there is a differance between what i can get in my car and me going "I have one bad ass car I just can't resist the urge to use it" :)

[Mehawsucc]

my car is an A4. i just moved back to michigan from florida about a month ago, on the way up my father drove his truck full of crap and my car full as well, we went about 65-70 the whole way to not get pulled over, my cars first tank was 25mpg and the highest was 28mpg, now around town i get 18-21 depends on how i drive it.

[raynor139]

If your easy on the gas and stay around 70 you can easily see 28-30 mpg on the highway with a m6.

[third_shift|studios]

keep something in mind: on your highway trip, you will hit stop/go bumper to bumper traffic, red lights and stop signs etc. I'm sure your campus has stop signs and a 15mph max limit...that's all 1st/2nd/3rd gear stuff = TERRIBLE gas milage.

[DOCJHH45]

Some MPG info...

My 2000 firebird V6 auto (all stock, had 70k on it), used to get 21 city, 26 hwy on 87 octane

My 99 TA A4 (all stock, 188k, 93 octane), gets 13 city, 18 hwy but I've beat the living shit out it everyday for almost 10 years

My 00 TA M6 (35k, 93 octane) got 20/30 when it was stock, with full exhaust and intake I'm getting slightly bettter, but I only drive her on the weekend and very nicely.

Hope this helps. Don;t settle for the v6.... even though they are lot cheaper initially to buy, the performance is so terrible you will hate the car.

[Speed Psychosis]

6th gear goes all the way up past 250 mph (if you have the power). at 80 you will be around 1600 rpm. yes evenat 80 i get great gas mileage even when going 80 on the highways

[Kup98ss]

My A4 2002 Trans Am gets 18/19 in city.
Highway my best was 25mpg.
I also have a 3.23 rearend
I'm sure the 2.73 would net you better mpg.

+1
now, i have a camaro LS1, and these things are amazing. M6 LS1 is almost idling on highway even when speeding in 6th gear. :true:

[Rosie25]

What is the stock rear end in the car.. 3.23?

[SAGGIN]

On my sticker it says on the streets my car gets 19MPG and 23MPG on highway. Also depends on what is done to the car.

[SAGGIN]

What is the stock rear end in the car.. 3.23?

mine has stockies which are 3.43s

[dphillips1984]

I have had 3 TA's in my time a 79 auto, a 95 standard, and currently have a 00 auto ws6. I loved everyone of them equal, but from experiance if your old man wont buy you what you want just wait and get it your self. Let him buy you some eco-job and save your money, and when you can afford it. You will appreciate it alot more. But anyway back to your question the sticker when the car was new says 17 city and 25 hwy. My 2000 has 137,000 miles, its 100% stock and it still gets 22 mpg. You cant buy american muscle and expect great economy, however my 22mpg TA gets better fuel milage than my Nissan Titan. It really all boils down to, does your old man want you to have a good car or a cheap car. Get F-ed and be a part of history.

When I was 17 I was pretty much in the same spot you are in. Here is 100% fact of what a ta get for gas milage. Took me a month and a half to get the permisson from my parents to let me buy one so good luck.....My choices were to super charge my 1996 blazer or get a LS1 thank god I went with the LS1 haha.

anybody have the window sticker for a manual??? i would really like to show one of these to my father...

[Kup98ss]

What is the stock rear end in the car.. 3.23?

All M6s have 3.42
A4 could have 2.73 or 3.23

[joejenkinsglass]

23 mpg highway.. are you running stock gears...?

yes stock gears 3:42 it is a convertible so that probably hurts mpgs a little. I don't drive them much though

[greenTA]

go with the M6.
I'm not so sure about the 25mpg's though. When mine was stock it probably got close, but with the cam and 4.10's i'm getting considerably worse.
Be careful with the car. I'm 16 and got a 98 T/A as my first car. Almost a year now and i've NEVER been pulled over...you just have to know when and where to have fun.

[TmaxicanA]

dont let those people who flame on A4's sway your decision. i have a A4 in my TA, but my dad has a camaro with the M6. and i get to drive both of them all the time. i like my auto more for racing and just driving around town...makes it easier (shift kit an auto wether you stall it or not)
but when i want to speed about town and drive for the heck of it i like the M6 more because your in complete control and its easier to show off in lol.
my auto stalled and shift kit TA gets about 10..and when the pedal isnt threw the floor, i get about 20 mostly highway driving.

[Speed Psychosis]

^ lol you just flamed the a4. your highway gas mileage is not much higher than my city. autos really need a stall to be fast and have better response but that greatly hurts your mpg. since your dad says it has to have good gas mileage, the a4 is out of question, especially if you want to modify your car.

[iam_dale]

I got 27.75 today w/ the windows down rollin' 80 on the hwy. Got about the same a few days earlier w/ the T-tops out.

[Mastermindc3pro]

Ive heard of people who fool around with their injectors and can get high mpg, see if you can find someone local to you who is good with that.

not sure how I flamed it, but whatever. autos are fine untill there stalled they still get great gas milage for what they are. if you plan on stalling it, then your dad might not be to happy with the mpg.

[Cutlass]

anybody have the window sticker for a manual??? i would really like to show one of these to my father...

Yeah I do. I'll scan it tonite! I think it says 19 and 28mpg for a 99 formula M6.

[jprice]

i just drove from detroit to columbus and back and got 27.3mpgs and thats at 70-75 mph the whole way other than some city driving. Also if you have a good driving record insurance shouldnt be to much of an issue i pay 103 dollars a month for my ws6 convertible, but im 28 with only a couple of tickets good luck
