I have a 96 V6 with the same 3.8 that your g/f has and I get around 18-22 in town depending on how I drive it and when it's anywhere in the ballpark of peak performance I get well into the 30s. I took it from south central KY to central NC on 14 gallons of gas and my trip odometer read at least 460 miles (I don't remember the exact number off the top of my head. Keep in mind that's going through the mountains, plus the terrain in SC KY isn't exactly the best for fuel mileage as well. And it was bone stock except for the Flowmaster muffler. One in two out. It blows people's minds that i can get that kind of fuel mileage. I get better than most 4 bangers do running 80 mph

 

My 01 TA T56 will get 31mpg with only highway driving at 80mph. (Fill up right off the interstate, drive many miles, get off and fill up again)
The strange thing is, if I keep the car at only 60mph on the same road, (Very hard to do) I only see 26mpg. I only tried the 60mph test one time though.

 

I believe Fbodfather said that we will all be pleased with the MPG of both SS models. He said that the new EPA method of calculting MPG made the estimate lower than most will actually get.

 

6th gear works fine as a large overdrive on the Z06, no reason they couldn't do the same for the SS. Even 5th gear should be very tall.

 

My '06 GTO M6 3.46 rearend w/ .57 overdrive gets a repeatable 25.2mpg at 79-80mph.
rating is 25mpg.
When I slow down it goes up to 30mpg range.

 

Can someone explain the EPA test measures? I have no idea how the LT1 M6 could be rated at 15-24 mpg on today's system. My 1993 TA M6 got 3.23's but a steeper gearbox (2.97 1st vs 2.66, 0.62 6th vs 0.50). When I was 16(with low 2 dollar gas) and first got it I romped the **** out of it with no highway driving and got no lower then 16. When my T/O bearing went and reving over 2000 would cause the car to shake like hell I drove it nicely around town and got 22-23. Never really did a highway trip so I can't comment a highway number.

 

well.. didn't the ls1 camaros weighed in at 3400lbs? hm.. guess those 500lbs difference will really hurt.. a bigger engine and what not will hurt... the 6.2 is an AMAZING engine... but the weight is a penalty...

 

not on the highway. Weight is negligible when you're at-speed. It could weigh 5000 lbs and it wouldn't make a huge difference. What will hurt is aerodynamics....which isn't stellar for this car.


imo, I think the EPA will rate the LS3+manual @ 23hwy, and the L99+auto will get a 24hwy rating. But in the real world; I think both will return close to 30hwy. Am I wrong? Probably.

 

weight still makes a noticeable difference when at speed. When I worked at honda, the element and accord had the same engine, but the element weighed more and got ~3-4 mpg less from what I remember.

 

but what played more of a role in the mpg between the two? weight or aerodynamics? If an If an Accord weighed the same as the Element what would the difference be?

 

Aero.

 

Some people don't get that accelerating weight does have disadvantages.

 

not trolling guys, but a counterpoint.

if i had a car. any car and it weighed 4000lbs, had a larger motor, had horrible aero. used 93 octane. costs $4.00+ a gallon to fuel it. and i tried to sell it to a dis-interested 3rd party.(non biased car buyer).

how many do i expect to sell?

then you give that car a bazillion hp. and price it too high for the average buyer to purchase WHAT DO YOU HAVE?

a ford GT500, a 2010 Z28, and a dodge challenger SRT.


no wonder they are asking you and me to bail them out.

GM lost 52+ billion in 19months. ford and dodge more than their share.

a v6 challenger costs $34000.00 i looked at it yesterday. a v6 camaro zeta car?

i am an enthusiast like everyone else here, but this is madness.

 

How in the heck to you think a V-6 Challenger is 34k If you go to the Dodge web site they start at under 23k and the R/T V-8 starts at under 30k. And I think the manufacturers that you listed would like to sell the V-6 counter part of the cars listed, the top of the model cars you listed are very low production.

 

dont ask me. i just looked at the pricetag. the dealer had 4995.00 in dealer added options alone.

call gary matthews chrysler in clarksville TN phone number # 931-552-7100 tomorrow and ask them about the black v6 challenger sitting in the final prep area. they can explain it better than me. i just looked with my eyes. and my wife was suprised too.

i fully expected a cheap car. that was not cheap.
