Answer 1

Seattle Metro’s Hybrid Bus Fuel Woes

Seattle Metro’s GM-Allison diesel parallel-hybrid buses are falling far short of the promised fuel savings of 40%—in some cases, delivering worse mileage than the older (and dirtier) dual-mode Breda buses they replaced, according to a report in the Seattle Post Intelligencer.

The paper first reported on the problems with fuel economy for the New Flyer buses in December 2004. (Earlier post.)

Metro owns the largest fleet of the GM parallel-hybrid buses in the world. New York is building its hybrid fleet with series-hybrid buses from Orion, a division of DaimlerChrysler. (Earlier post.)

There appear to be several issues facing the Seattle buses.

First, the hybrids are used on suburban express routes with more highway mileage—a situation in which the electric drive doesn’t contribute to fuel saving as it does in urban stop-and-go driving.

Second was a switch from Cummings diesel engines to Caterpillar engines, along with the need to meet more stringent emissions requirements.

Answer 2

No, a flex fuel engine means you can use up to 85% ethanol, and it's just as efficent. Not to mention cheaper. Flex fuel engines can also use regular gasoline if there arent any ethanol pumps around. There are currently 3 million flex fuel cars on the american roads today, and most people don't even know they have them!

Answer 3

A flex fuel car is JUST AS EFFICIENT as a regular car.....

It's the Fuel that isn't.....E85 gets 3/4 the mileage as 100% or 90% Gasoline.....but it's 85% alcohol, which is better for the air.....

I know my next vehicle will be E85.....or diesel.
But I'll definitely use regular gas for long trips......
