Funny but not surprising
Vote first, then watch the video.
I voted yes. This builds exactly upon what I said in the Civic Hybrid thread, it turns out that if you accelerate hard and drive very fast, or if you drive up a hilly highway, or a steep incline in the rockies, you will get terrible gas mileage.
The reason why is simply because at some point the small 1.3L or 1.5L for the Prius engine becomes inefficient for the task at hand. If you drive like a grandma, then the tiny engine gets 40mpg, and 40mpg was pushing it. If you drive downhill you can expect 50mpg if you coast downhill, but then again if you had a BMW X3 and put it in Neutral the engine would idle at 600rpm, and you could roll down the steep decline easily, even having to ride the brakes in some instances.
The BMW engine gets better mileage than the Prius when you put the pedal to the metal because the Prius had to floor it, it's not designed for a track, while the M3 could just coast and shift at low rpms.
A silly comparison, but I knew it all along, when I drove the civic hybrid over the continental divide in Montana, I was getting my 38mpg average reduced to 32mpg, meaning I must have been getting mid 20s mpg. I also had to lay off the 80mph cruise control, since I thought I was gonna break the 1.3L engine since the CVT kept it at 5,000rpm, and this was no air cooled track engine.
I would only buy a Hybrid if the following conditions occured: first if you could claim the Tax deduction, then if they DID NOT charge a premium over MSRP (this new trend is nonsense, infact I got 1,500 off MSRP when I bought it), and last if you drive only in heavy traffic city areas with a lot of red lights. Even then you're probably gonna do just fine, and be just as environmentally friendly if not more by purchasing a regular corolla, civic, elantra, focus, cobalt, etc...
