It's my opinion that if you tune an engine specifically for the purpose of efficiently going 40 mph, acceleration be damned, and make appropriate adjustments to the rest of the car, you're going to get far in excess of 60 mpg anyway. I used to commute from Kansas City to Topeka (about 100 miles each way) on I-70 in my 91 Mustang and when I put the effort into it, was able to consistently get 31 mpg out of it. Mostly that involved advancing heck out of the timing (which necessitated premium fuel), removing the air silencer, overinflating the tires, zero toe-in, max negative camber (makes the tires ride more on the edge to reduce the contact patch in straight-line driving) and a 2.73 rear-end. Combine this with a driving style that coaxed maximum economy on the hilly drive. 31 mpg isn't bad for a 4-cylinder car, but this car isn't one. It's a 225 hp V8! I could get high economy, or peel the paint off almost anything out there, with the only change being the amount of throttle. BTW, I still have that car and you can check out the rather interesting new use that car sees at sound.net <g> The point I'm getting at is that 93 mpg is, IMO, indicative of some kind of technology that actually works , but it's not earth-shattering by a long shot. Now if they were more thorough, they might've done exactly the same mods to a control car, except for the engine, down to the same tires and same gearing. Then they could've also done comparative 0-60 times in both cars. If they could beat such a control car by 50% in economy, and not give up too much in 0-60, that'd be earth-shattering. I would think this would've been possible, and with even higher economy figures. I take it there's no electric motor assist. Too bad, as I thought that's one of this company's specialties. And an electrically-assisted 23-horse diesel-powered Metro should be able to blow the doors off a stocker. Electric motors are *much* more torquey off the line than comparably-powered gas engines. I'm in this stock right now for the following reasons: 1. European connection. 2. Possibility of dyno figures soon being published? (hope so!) 3. Possibility of other news from company soon (or so some say) Aside from that, I don't think this whole thing is being managed very well.
