Yeah, while it is a nice sentiment, it is based on some seriously outdated enviromental data and some skewed interpretations.
Not that it changes how I feel about the prius as just another good shot. Diesel is still king of renewable biofuel and low emmissions.

I've heard similar analysis claiming the energy used to make a vehicle is far more than the vehicle consumes during it's lifetime. Hence M-B's that last 300K+ are preferred. Ok, but I'm sure it's complicated to estimate accurately.
And if, as the 'Dust to Dust' analysis states, the Prius averages $3.25 / mile over 100,000 mile lifetime, thats a total 'cost' of $325,000!
Subtracting $25,000 for fuel leaves a $300,000 'production cost'.
So how can Toyota sell a car that 'costs' $300,00 to make?
Something doesn't add up. How can the combined material and energy and labor costs be higher than $20,000?

As you infer Biodiesel, there is something dodgy in the basic assumptions like the ratio of resource needed to build and to run a vehicle, not to mention the 300,000 assumed life of the Hummer compared with the 100,000 assigned max to the Prius.
