Our Prius is approaching 83,000 miles and so far it has been a great car with an average calculated mpg of at least 50 mpg. But, I am looking at the new cars on the horizon, I see the C-Max, C-Max Energi, Ford Fusion Hybrid, Ford Fusion Energi, and I am sure, and just a matter of time, Kia, and Hynundai will also have other hybrids instead of their current Optima / Elantra platforms. I believe there is always room to improve design and efficiency with nearly all man made products, and I am sure the Prius can and will be improved. I believe lighter Lithium type batteries is a good start for the regular Prius. In probably another 2-3 years we will be looking at probably buying another vehicle and even though we love our Prius, there should be a few more choices out there that we can take a long serious look at. So, I will keep an open mind. I wonder if many of our Prius Chat members feel the same way as I?
