Why use a turbocharged engine for the backup generator? Wouldn't a naturally aspirated engine be simpler, cheaper and more reliable? Also, it would not require more expensive high octane gas. Typically turbochargers are used to boost horsepower for acceleration. If an engine/generator runs at a constant speed and load won't that make a turbocharger unnecessary? Would it be a water or air cooled engine? This may be a good application for an air cooled engine. If the engine runs only when the car is moving there would be a constant flow air for cooling. An air cooled engine would eliminate the need for a radiator, pump and what not for cooling making it cheaper and lighter. What other engine options have been considered? Will GM offer different engine options.
