View Full Version : fuel economy(my first post)
petegtsv10 10-25-2006, 06:54 PM I bought my tC as a daily driver. It is a great alternative to all the boring economy cars out there. I should take delivery later this week.
What kind real world mpg do you guys get?
I get 23mpg city/hwy. I have a 5spd. It's a shock for me because I used to drive a 5spd Corolla where my average was 32mpg.
However, the tC is more powerful and a "cooler" car than a Corolla.
disgruntleddutch 10-25-2006, 07:09 PM i get about 25 mpg city/hwy. About a hour commute each way every day of which 30 minutes is sitting in stop 'n go traffic.
I drive an auto.
engifineer 10-25-2006, 07:21 PM I have always averaged about 24mpg. On trips, I ususally see about 30mpg on highway. In heavy city driving only about 21.
tc_monkey 10-25-2006, 07:53 PM 23 to 26 mixed highway/city ( much better than the 12 I get with my Jeep®)
draxcaliber 10-25-2006, 08:16 PM when i drive to school once a week, it is a 125 mile drive, i use half the tank, which is about 17 mpg, ofcourse i'm driving before dawn, and going about 90 mph since there is no traffic, but it is up alot of mountains. when i drive back home, i used like 3/8's of a tank cause of the downhill slopes, and the traffic makes me travel slower, like 70 to 80 mph, i get about 34 mpg. so gas mileage gets really bad if you push that needle into the second half of the speedo.
TcSpaWN 10-25-2006, 09:17 PM i get about 26 mpg
Nick06tC 10-25-2006, 09:21 PM 22-23 city 27 highway
With a bunch of mods.
93_Snake 10-25-2006, 09:44 PM I usually get around 27 mpg driving a steady 75 mph on the highway.
nodsetse 10-25-2006, 11:12 PM Easily less than 20mpg, in the city, when I drive aggressively.
mike6789k 10-25-2006, 11:23 PM nodsetse, same here... right now im about to refill my tank and ive only gone 207 miles, LOL!
TongMan 10-26-2006, 12:00 AM I get around 23-25 mpg and i'm supercharged.
CuRiOuSfIsH 10-26-2006, 01:19 AM I have a 07 MY, I drive about 70% highway, I have achieved 27 w/ me pushing the car around a little. 30 MPG with just normal driving.
I may be an odd one, I usually get higher MPG than most ppl.
docjpv 10-26-2006, 01:23 AM i guess it really depends on how heavy your foot is on the gas pedal..
i average from 24-26.. 60% city, 40% hway.. going about 5 miles above the speedlimit..
Disodium 10-26-2006, 01:25 AM 30 MPG 70% Highway, shifting at 3K or lower
Spect2K3 10-26-2006, 02:13 AM Mix of highway/city driving. I tend to hit the gas a bit. I get avg 24.5 mpg - always 5spd tranny
Diversion 10-26-2006, 03:05 AM I put 400 miles on my first tank of gas (the tank it came with when I bought it). About 50/50 city/highway driving. That's pretty impressive to me for a 2.4liter.
Diversion 10-26-2006, 03:29 AM Well keep in mind the 07s do get slightly better all-round gas mileage over the 05/06s.. we have higher compression which makes for a more efficient motor. And I think our cams might be slightly different too, I say this because the midrange in my 07 isn't as strong as my girlfriend's 06. But the 07s seem to pull harder in the higher rpms.. Could all be in my head though.
CuRiOuSfIsH 10-26-2006, 04:21 AM ^^^ perhaps not, torque did drop by 1 but power peaks 300RPM higher, and it's not known how long that lasts for. A dyno chart would answer some questions.
Diversion 10-26-2006, 07:06 AM I just know while cruising in 5th gear on the highway, her 06 will pick up and take off a lot faster without requiring a downshift than my 07.. it's definately not as strong in 5th around 65mph.
Not complaining, the 07s should be a better car to modify and get more speed out of.. I'd like to see a dyno comparo of the 05/6 to the 07. And a roll race between the two.. I have a feeling the 07 drop kicks the 05/06s in the higher speeds because of the new power curve.

petegtsv10 10-26-2006, 01:21 PM When I started this thread I expected to hear of higher mpg #s from owners. I have a feeling that the cars >2900# weight has something to do with it. My ZO6 is about 3100#, has almost 600hp and regularly gets 20 city/29hwy if I drive with some restraint. (its an ULEV, too) I'll be curious to see what the tC gets on the same routes.
draxcaliber 10-26-2006, 01:35 PM weight has more to do with fuel mileage than power. for instance, how come the pontiac soltice can't get much better gas mileage than a vette?
Nick06tC 10-26-2006, 01:48 PM Weight is a direct factor, but has ALOT less to do with MPG than gearing. Having a 2000lb car that runs 65MPH at 7000RPMs will get worse gas milage than a 4000LB car that runs 65 MPH at 2400RPMS. (numbers hypothetical and have nothing to do with a specific car)
In the tC we run at highway speeds, over 3200RPMS. That is horrible on gas milage. The more that crank is rotating the more fuel is needed to keep those pistons rotating it. Weight becomes fairly negligable once up to speed. It becomes a factor of rpms and drag.
Run ANY car in 4th gear at highway speed and see how your fuel economy changes, then come back and try to say its all about weight.
draxcaliber 10-26-2006, 02:00 PM i wasn't saying it was the only factor, i was just quoting car and driver when somebody asked why a soltice can't get much better gas mileage than a vette.
Nick06tC 10-26-2006, 02:08 PM Its all good, I wasnt refering sololy to that post. I was refering to the common thoughts that most people think weight is the determining factor of fuel economy.
06CStC 10-26-2006, 02:48 PM I get about 25-26+ mpg mixed hw and city. During the summer, it was mostly city and i got around 23 or so. Pretty much i've gotten wat was advertised, hehe.
SmokingTires 11-09-2006, 05:23 PM My first tank I got 27, and on my second it was 29. I am still on my third tank...
50/50 Freeway/City
gjpjr84 11-09-2006, 05:44 PM i get 25 mixed city/highway.
and on a 600 mile drive to oklahoma and back i averaged about 95mph and got a shocking 30mpg.
draxcaliber 11-09-2006, 06:21 PM so i guess the tc's biggest gas mileage robber is the gearing. on my 125 mile drive that i do in the dead of morning with nobody else on the road, i maintain a steady 90 mph and get 17 mpg because over an hour at about 4500 rpms burns alot of gas, the way back with traffic going about 70 mph gets me about 34 mpg. at around 3000 rpms.
paul34 11-09-2006, 11:08 PM I'd rather have the shorter gearing so that I can get going when I need to
Regardless, I calculated my MPG for my last tank (so take it for what its worth since its not an average) and I was pleasantly surprised to find I got 30 mpg. This is all "city" driving, as well :)
engifineer 11-09-2006, 11:37 PM why would you expect to hear of higher numbers? People are getting right at the advertised averages for the car.
engifineer 11-09-2006, 11:43 PM Well keep in mind the 07s do get slightly better all-round gas mileage over the 05/06s.. we have higher compression which makes for a more efficient motor.

No, it is a 9.6:1 compression engine, same as the 05/06 models. Same mileage (23/30), same power other than 1 more hp and 1 ft*lb less torque.
gjpjr84 11-10-2006, 01:13 AM :lol: wow i missed that post.....
