Challenger R/T - Gas Mileage

I'm planning to buy Challenger R/T and I just want to know approximately how many kilometers can I make on a Dodge Challenger RT?
Thanks!

For me about 23 highway and 16 around town (depending on how I drive it). If I let the computer track it over a month of split highway and city driving it is almost always 18.9 MPG average.

If I disable the MDS system then it's about 20 highway and about the same city.

Well...my car getting 25mpg highway was a major selling point for me. I just did my second fill up. With the first tank of gas I got 20 mpg but that was with a probably as much city as it was highway. The second tank was almost all highway. It actually went down! About 18.9 mpg!!!

Granted a fair amount of that highway driving is around 80mph but it's not like I am flooring it to get there and the MDS is in full effect as well. I am a bit disappointed. I am thinking the 25mpg rating must have been achieved at 60 mph or so.

I think it has to do with the fact that 80 mph runs the engine at about 2500 RPM with the auto. I think with the 6-speed manual it would only be running at about 2100 or so and I feel I would definately be getting better gas mileage. I wish I had realized this before I bought the auto! My 1500 Ram truck gets roughly 17.5 mpg highway and that is running the same roads and speeds as the Challenger.

I get a little over 25 on the interstate but I have a K&N drop in filter that added a little. It will take alot to make up for the cost of the filter. I don't look at mileage in town cause my foot won't behave and accelerate slowly.

A few weeks ago I took a 400mile trip with out 09 300c and the whole trip was pretty much over 75mph... (75-80)
The manually measured result was just over 25mpg... I would think yours should be in that ball park.

I will say that gas really effects it... Our driving around mileage(hwy/rural) used to be around 22 when we could still find real gas. Since the kiwi down the street changed over to 10% like everyone else, it's dropped to 20. In the winter, on winter blend pisswater we barely top 18, and have gone as low as 15mpg. But it's never that bad on summer gas. Can't wait to see how bad it gets when the new Gov approved 15% panther piss hits the pumps.

The picture next to your screen name shows an SRT8 emblem... if your car is an SRT8 then your mileage may be close to normal.

With the 6-speed/ 5.7 I see averages of 17.5 - 18.5mpg driving around town

on long stretches of highway 27.5 - 28.4mpg is typical in 6th gear (usually runs 1.5-1.8k at highway speeds with the .50 top gear).

So, in short the 6-speed seems to do better than the EPA estimates of 16/25.
