My Vibe gets about 21 mpg. Most of my driving is on the highway. It said on the window when I bought this shoe box 33 mpg highway 29 city. Is it this winter reformulated crap gas or is it the Vibe? Here I thought I would get a car with a four banger and I would save on gas. Heck my old Buick Skylark got better milage then this piece of junk. My Vibe has 28,000 highway miles on it.
Could be a lot of things - cold weather, reformulated gas, your driving style ( do you floor it every time you take off and drive 85 on highway? ) It's still under warranty - why not take it back to the dealer and ask?
"Everyone" keeps coming in here with that complaint. Could be the fact that its nothing more than a van with high drag and that motor has no LOW END torque or hp to move it effeciantly at highway speeds. All epa stickers are rated on a treadmill and they do a poor job of factoring in drag coefficiency I think.
123@6000 hp
118@4400 torque
2980 Curb Weight
4.24 Final Drive Ratio
Your skylark done better because it was more squat and had more low end torque where it was needed and a higher final drive ratio. The lesson here is, dont buy a van or any big vehicle with a 4 banger. Its just to overworked. Remember all the smoking chrysler minivans? All 4 bangers. I'd have to drive my bonneville really really hard and aggressive on the highway to be getting 21mpg...AND IT WEIGHS MORE! I can get a good 28-
30mpg running a constant 75mph. Hopefully you still have your skylark.
I think a 3800 would make the Vibe a sweet efficient runner.
