Absolutes about engineering tradeoffs are not really my mindset (as the paragraph from which the quote was taken shows). I was responding to USB who is frequently using absolutes, e.g. suggesting that lugging the engine around makes the Volt inefficient (even though my milage and efficiency far exceeds his Prius Performance). Of course, I do see various absolutes, e.g. renewable energy to use is better petrol use. I think its going to be a great car - though wish it was available years ago and Toyota was more agressive in pushing the engineering. I don't attack the PHV and I do/will defend the Volt as a well engineered car but will question unsubstantiated claims and bad/questionable data.
