Your first post, so welcome to the forum. It takes a lot of time to search through all the posts on the subject of MPG techniques, but it's the best thing to do if you don't want to miss the excitement of the same old questions; same old answers, BUT, you just might get a better base of knowledge of the CRZ and MPG's by reading it all--answers to questions you didn't even consider asking. Here's my take on your specific questions:
1. Is it possible for me to achieve above 40 mpg in stop and go traffic?
**Best you can do is work on your braking technique--and judging the traffic ahead--coasting in (in gear, of course) to a gradual stop with your foot barely touching the brake, will inititiate auto stop sooner.
2. Is it better to accelerate faster to get up to speed and then back off the throttle? Or would it be better to slowly ease up to speed?
**If no traffic ahead, I accelerate very aggressively to the speed I want to maintain, then feather the throttle to maintain speed, but that technique is useless unless you have miles of uninterrupted road ahead of you.
3. I've seen some of you talk about "pulse and glide" but haven't really seen it explained. Could someone please explain this to me?
**Eh, I think I do that at times, but have never given it a name. More or less, it's keeping up your momentem by blips of acceleration and backing off, more like feathering the throttle after the initial burst of power. Watch your MPG meter as you do this, and you'll see a one second or two of 25 MPG, followed by 75 MPG figure, slowly dropping back to around 40-50 MPG, which uses 100% of the IMA for the quick power up and initiates the regen on the gradual slow-down to keep a charge to continue the cycle (if the terrain permits.)
4. In my case, with constant stop and go traffic, would Normal mode be better for MPG or would sport mode be better? I've read some of you say that you get better MPG in sport mode.
**Just think of the different modes as giving you three different values of throttle response, and depending on your style of driving, you may find you get better MPG's in a certain mode in traffic, while the same mode gets you worse MPG's on hills or Interstate.
5. I tend to use my cruise control a lot. Even when I'm on a 30 mph road. Will that help my MPG or would it be better to just not use it?
**Sounds like I use cruise just like you do, and for me, it absolutely improves my MPG's because otherwise, I'd be driving 20-30 miles per hour faster, and wind resistance the true nemisis of MPG's. 10 MPG difference (or more) between driving 45 mph and 90 mph in my own actual experience.
6. When it's not so hot and I can actually use Economy mode, is there really a significant difference between Economy and Normal mode?
**Biggest saver for ECON is disabling A/C while in auto stop, and you can get the same MPG's in NORMAL by just not running the A/C
