Series vs Parallel - Overcharged!: Chevy Volt | Honda Insight | Vauxhall Insignia

Overcharged!: Chevy Volt | Honda Insight | Vauxhall Insignia: "why would GM choose to adopt an architecture that is likely to result in cars which will cost more to build and run than the alternative apparently preferred by most, if not all, of its competitors? One explanation, supported by a review of some of GM's concept projects, seems to be a desire to create a single platform capable of supporting the full spectrum of hybrid, fuel cell and battery-only vehicles."
