I think we need to remember that the 1992 Metro 5 speed is rated at 38/40/44 on the current EPA standards. Many of you have proven that's not a good representation of the possibilities. The 1.0L 3-cyl Fiesta will have lots of untapped FE potential for drivers like us. It may out-perform the metro in the hands of a good hypermiler. But crucially, it will also have superior power for towing or hill climbing whenever needed. It'll have superior safety equipment. All around, it is a more advanced car.
Anyone who loves P&G techniques should remember, this car's turbo delivers much of its power in the 1500 rpm range with little delay.
I think it's a wicked-cool little car.
And as Frank says... if you really want less weight there will be half a ton of stuff you might delete.
