How 'bout:

"I've got a natural Hy" or "Drive Hy" - um, okay maybe not...

"YEE-HAH" - yes, this is the name I gave my car, but with a V6, I think it is appropriate (maybe only those of us in TX will get it though )

or something a little more low brow - "Passing Gas in my new Hybrid" or "I pass gas - How 'bout you?" (sorry, it's late...)

or maybe you could market a part of an extension cord that will stick out of the gas tank (you know, like the tiger tail) Of course you would have to make it so that it wouldn't scratch the paint

P.S. I would love to buy the lic. plate bracket - but they are illegal here in TX now since they "cover up" the name of the state up at the top - and I have this on good authority since it was a cop who had to tell me this (and regrettably, that was NOT the reason he pulled me over). These politicians need to find a better way to spend my tax dollars...

(and I am now hoping I have enough posts to qualify )

 

Here's another:

"Gas, Shmas... Hybrids' got game"

or

"Hybrid creed: most practical auto since Model-T"

 

Jason,
I think we're all putting in some effort here. Perhaps you could award a winner and a 2nd and 3rd place runner up getting a prize as well. (like a license plate holder.)

Just a thought.

 

OK, I can't get this slogan thing out of my head.... here's a few more...please Jason end this madness!!!

"Hybrid, if they build it, you will come, and go"

"HYBRIDS fuel less"

"MY HYBRID HATES YOUR CAR"

"MY HYBRID IS SMARTER THAN YOUR CAR"

"HYBRIDS USE, NOT LOSE POWER"

"HYBRIDS S T R E T C H YOUR DOLLARS"

"WHY ARE HYBRID OWNERS SO HAPPY?"

"HYBRIDS WILL MOVE YOU"

Ack, my brain is fried .......time to quit.

 

"My bid -hybrid"

or

"My bid -go hybrid"

I also like "You'll thank me later" by tdmsu

 

more joule less fuel

preserve the reserves: conserve

saving oil with my tesla coil <= you said catchy, not technically accurate

sip, don't guzzle

Warning: I'm driving like I've no brakes

 

If you hate my car you're probably jealous

My MPG is is twice yours

Pioneer wagon (or hatchback I guess, this is mainly for the Prius)

They'll all be hybrids someday

Look Mom No Plug!

I'm one of the first enlightened ones... go hybrid

Just a few more ideas...

 

Someday you won't wonder why I'm driving this way.
It's so quiet because it is OFF.
Mine turns ON instantly.
Save the (dead) dinosaurs!
Someday you will be driving one too.
GreenHybrid.com RULZ! (blatant brown nosing)
Jason for president! (really blatant)
I want to have Jason's baby! (too far?)
Nice SUV
Never had mine off road either

 

Haha. I think a "Save the Dinosaurs" bumper sticker would be hillarious.

 

The first round of "catchy phrase" nominees have been selected. Five new bumper stickers have been added to the online store. If one of them is yours, you're in the running - congratulations! See the bumper stickers here.

Keep the ideas coming. A winner will not be announced until 15 products are added.
