Hybrid Concept Car Achieves Record Fuel Economy

I made a comment to that article, but the comment is waiting for moderation, so I'm repeating it here (for my own ego gratification?) ;-)

How was the MPG figure calculated? More specifically, was the first 22 miles (on battery power) figured into the calculation? It would be much more meaningful if it were not--I'd like to know how much efficiency is built into the car / diesel engine, and not how much is faked by using a different source of energy.

Figures like these are like giving us one equation with two unknowns. If the MPG figure includes the first 22 miles, what was the average trip? I can imagine doing the calculation based on no trips exceeding 22 miles and coming up with an infinite MPG figure.

Another way to get a proper (imho) figure would be to start all trips with zero charge on the battery. (Presumably the diesel engine also recharges the battery.)

Yes, GM started that silly calculation.

At first the Volt supposed to be an all electric car, now it's a hybrid with an ICE in it. We are being lied to from everywhere.
