    I believe that the 2010 Prius is the only
    car that does not have any belts, i.e. alternator/ac/serpentine
    etc.

    Is there any other cars out there with no belts besides the Nissan Leaf?

    Chevy Volt - pretty much most cars that are hybrid - since they run AC etc from the HV battery pack - no need for a belt.......

    Some hybrids still have traditional A/C systems.

    Most hybrids still have traditional belted water pumps.

    John's correct. 2nd gen Prius still had a belt and 1st gen Prius had a belt driven AC compressor along w/some other Honda hybrids.

    The Volt seems to have a belt given http://www.chevrolet.com/assets/pdf/owners/manuals/2011/2011_chevrolet_volt_owners.pdf and Chevy Volt Owner's Manual.

    Also, GM had their mild [ame="http://en.wikipedia.org/wiki/BAS_Hybrid"]BAS Hybrid - Wikipedia, the free encyclopedia[/ame] (BAS = belt alternator starter) which has now been rebranded was eAssist. GM brags about eAssist at http://media.gm.com/content/media/u...ws/us/en/2010/Nov/10los_angeles/1115_lacrosse.

    I am pretty sure it's the only beltless gas powered car on the road in america.

    There's still a chain inside, looping around the crankshaft and the two valve cam shafts up top. I think that's it though. The alternatives for that torque transfer are a toothed belt (such as Honda uses a lot, prone to stretch, oil foul, requires replacement around 100000 km~ intervals), or gears.

    Well, I like the idea of not having to change the serpentine belt, or other belts every 30,000-60,000 miles.

    Your wasting your money if you are buying new belts every 30-60k. Most belts last at least 100k i have seen some 8 years old and more than 100k.

    CT200h and the upcoming Prius v have no belt or clutch.

    Maybe Tesla roadster? Not sure about Fusion hybrid or the upcoming C-max hybrid.

    I much prefer the chain system. It probably will last the
    life of the car.

    Replacing those toothed belts is expensive, espically in my 2003 Jetta TDI Wagon.
