Yeah, they never said the make/model of the bubble bike but they claimed it was the most efficient bike you could currently buy. As for the testing, all were tested identically. They ran the sniffer up the tailpipe of each vehicle and ran their course. For the car vs bike of each era section they hit the highways and city streets with the bike following right behind the car so it was the same route/acceleration/conditions for each. They found that during that time span the bike consumed less fuel, produced less CO2, but every other gas they tested for the bike was off the charts. Like everyone else has said, those bikes were carbed and no emissions devices. The second half of the program they tried to make a bike as clean as a car by working on the aerodynamics. They bought the most efficient modern bike you can buy, said it had fuel injection and cats, tested it on a track in stock condition, then built a light-weight teardrop shaped shell to put around it and ran the course again. It performed much better, but still not as clean as the cars.
I too am a little befuddled by how something can burn significantly less fuel but produce more emissions. -Kyle On Thu, Oct 6, 2011 at 9:30 AM, James O'Gorman <[email protected]> wrote: > *It was both, and it was only a 250cc > > On Oct 6, 2011, at 7:25 AM, Kurt Nolte wrote: > > Javier, in this instance the emission controls weren't the same between the > two, with their bikes being carbureted and no catalyst.
