Just curious...It seems to run about 1000rpm more around town....Ie.., 1500 Vs. 2500 I cant see good MPG in that...

I stopped after having the no power problem that many others have had. Stopped shut down restart and it was fine. But figured leave it in normal or any other singular mode, so it less for the computer to have to think about.

I'm thinking of buying a Throttle Controller that speeds up the pedal ratio, thinking it might help that flat/hesitation that I get off the line once in a while. I had heard that the Sport mode does that and also tightens up the steering also but I find it taxing on the engine and my pocket book, running around town at 2500rpm when the normal and smart modes are at 1100-1500 rpm...

Most sport modes, on most cars block the highest gear ratio from engaging.......

That will be a waste of money. It makes no change to how the engine performs. You can do the same thing by pressing a little harder with your right foot.

Definitely cost you more $$$ with the noticeably higher mpg. Especially with current gas prices, I did some evaluation with mine and the decrease in mpg was about 25%.... considerable.

I didn't find that to be true at all, but didn't do much city. Mostly back roads and highway till I had that power issue. Now I drive in normal only. When I was driving in smart mode, I fuel average for nearly 4000 miles was 25mpg and highway would get over 31mpg and sometimes on back roads over 35mpg. I don't get near that in Normal

So you get better in Smart mode over Normal ?

 

[PK 62]

I've tried both, and in my 3+ months I run Smart maybe 90% and I feel there's a slight improvement

 

[CASD]

I just did a tank in Normal and I got 20.8mpg But mine is stop and go 7.3 miles each way to work.. max speed 45 in the mornings but only 35mph going home, I'm going to run in smart this tank..

 

[PK 62]

I'll do comparisons too, but I need mid spring and onwards to get a fair comparison

 

[Akfan]

I've had several that did get better in sport or tow than they did normal or eco in city or backroad driving. Less gear hunting with these 8 and 10 speed vehicles.

Bound to be easier on the transmission as well. Not shifting every time you take a turn or curve.

I’m on a road trip right now, did a 4 hour stint from Toronto to Detroit on a tank and got about 28mpg going around 70mph, but drafting behind trailers, this route being a major trucking route, was easy to draft. But on I-75 going 75mph in normal, I managed just over 20mpg - no one to draft and still on my snow tires…

 

[Tedsky18045]

I did but that was also going into winter. So let's see now that the weather has changed. I will be paying very close attention over the next 2 tanks of fuel to see where my average is now

That's inline with what we see. If I'm in front in my real truck both of the Cruz that go on vacation with us can get closer to 28. On their solo trips it's down closer 23. Which is less than the big truck.

If they are kept down to backroad speeds around 55 they do better and get closer 28. But I'm still pretty disappointed for a modern 2.5

See this is strange, I have found that my SC like open air in front of it as opposed to so called drafting. But also I hate getting that close due to stone chips from crap kicking up from the lead vehicle.

 

[CASD]

The last I drafted..was the last time I took our ex-Fiat Pop 500 on the Interstate at 80mph.....I felt like I was reincarnating Evil Kivnel .....White knuckle fever lol

I think most on here are referring to a decent distance behind the leader. Not so much race car drafting but also not blazing through an 80mph wind wall either. I use to race sportbikes so I know what you mean though. An inch off the rear tire of the next guy and if one goes down the entire pack does. One guys steps out and fishtail ensue. Lol. Engines run warmer and less HP too.

In my experience when on the interstate a decent gap between vehicles still gets me better mileage. Usually though I'm the one in the lead on our family travels since I'm the one navigating. Im also usually in the civilian assault vehicle sized Suv or truck since I have 3 kids who are nearing 6 foot and my self at over 6. Small vehicles don't cut it for us anymore ALTHOUGH as a 6 foot kid myself in middle school I rode in my parents camaro and Mustangs. Lol. Would be considered child abuse nowadays.

Years ago in my Denali I followed a buddy of mine in a semi. If I stayed dangerously close it was quiet and I got nearly 30 MPG. If I got more than a few feet behind him I got terrible buffeting and the Denali got slapped around. Any further back and the buffeting stopped but the mileage savings were less. Same vehicle on its own got around 17 mpg.

I've not actually driven the Cruz much but I travel with one a good bit. Id think with the open front end design and the complete (and surprising) lack of any cold air intake anyway, that following and not getting fresh cool air wouldn't make a huge difference. Could be that it makes more difference though since the cooler air is finding its way into the otherwise hot air intake from the engine bay. And again both the Cruz i travel with are NA cars. I think a turbo would be less affected by the wind drag since it wouldn't be straining to keep 80 which is what the interstate we travel most is. Likely less affected by warm air and elevation too.

My ws6 runs considerably better in open air while my Mach one really makes no difference that I can tell. Both have factory cold air. Both claim to have "ram air" but any owner will tell you that is laughable. The air goes in through the hoods but then zigzags around through ducts and filter switching directions several times. My old IROC has a more functional "ram air" coming up through the bumper and into the tunnel ram TBI. lol......shame about that 305 though. I know what you mean about some running better in clean air though. Both the ws6 and the mach one can get 30 highway. Both are idling at 80 in high gear and can pull high gear. Neither will get 20 city though.

Got a tibit for yea .... Bought a New 1987 IROC 305ci Tunnel Port Injection... T-Roof Yellow with black interior and trim... $19,995.00
The Bee's loved that car more than I did LOL stop at a light and they would start buzzing you and always trying to build nest in the side mirrors...

Mines an 86 t top. Paid 800 around 1999 . Originally a TPI 305 car. Now it's a 350 from bit newer corvette but bone stock. Black with grey interior. Automatic. I love it. Complete dog compared to anything nowdays. Handles awful and terrible mileage. Lol. Sounds great though . And IMO was the last good looking Camaro.

But you know what I mean about the "ram air" on it . The air comes through big holes into the bumper up through two air filters in the top of the bumper and then straight into the intake.

On my WS6 and Mach one both the nice cold air comes in through holes in the hood and then goes absolutely everywhere around bends and twists before eventually getting into the intake several degrees warmer and in no way "rammed" Lol. On the mustang I really think the standard Gt sucking air up through the Fender was probably a better design than the mach ones hood scoop..... didn't look at cool though. Or sound it
