And the Volt is LOTS heavier than a Cruze Eco, almost 900lbs. Note the Volt is rated at 40mpg on the hwy, in the CS mode. The efficiency thing is a myth, the series configuration mode of the Volt is actually more efficient than the parallel configuration mode.. but only at speeds below 60-70mph or something like that.. the SAE papers GM recently published go into lots of details. Apparently there are lots of losses in transmissions. The Volts 1.4L is limited to 4400 rpm I believe, to keep NVH down. The Volt has a 53kw ICE/Genset (70hp) system solely driven by the requirement to cruise at 100mph with an empty battery.. a 35kw system would have been more than plenty for sane driving speeds, due to its nature acceleration would not have been affected. The sad fact is that any car sold with a 0-60 less than 10 secs is considered unsafe by many people.
