A small engine that is underpowered would work harder and burn more fuel then a larger engine. The weight difference from the i4 NA and the I3 turbo would be maybe 10-20lbs at best. Also dumping the turbo saves a few grand Since the engine will run at a steady RPM it doesnt really matter if its grown in size.

It was built by suzuki and used in the Geo. It had good pick up and ran 52MPG in the car I had. It's biggest problem was the engine had too much torque for the clutch suzuki matched it with.

It would also be cheaper to produce since it will go in the next generation Cobalt. Also not having a turbo will reduce the cost of the Volt. Has anyone ever had to replace a turbo on a car, they are not cheap. The only reason they can keep it offordable in the next Cobalt will be the mass prduction (100,000+ per year) of the car. The engineering for the motor is allready done, they use it in Opels and Vaxhauls (sp?). If you compare the weight of a 1.0L 3cyl with all the turbo related parts to the 1.4L motor, the weight is probibly about the same. Plus the 1.4L is really small, the block is about the size of a loaf of Wonder bread. The advantage of the 1.4L is that it would robibly charge the battery faster than the 1.0L.

You will need enough EMF (electromotive force) to propel/charge the volt when the batteries drain down. A 1.4 liter motor running at a static RPM can be very efficient. Make lite and reliable will work just fine. The turbo just adds more maintenance.

(120Volts * 15amps = 1800 Watts) Enjoy parking on the side of the road for 8 hours every 30 minutes of driving on the highway. You would get horrible gas mileage with a honda generator. They are efficient for the task they are made to do compared to their competitors, and thats about it.. 205 Fred

I visit mountains once per year with my car. On average quite often in my area. And when visiting mountain area I can drive my car at lower speed. Therefore I would name current Volt version Volt-Mountain since it has no mountain area limitation. On other hand I would propose for normal Volt to get "mountain mode". It means that batteries can stay fully charges and work in parallel with engine when elevation starts and charging when descending with regenerativ vraking. No advantages of being Volt electric but one can survive. I have feeling, that Volt will be designed for mountain area. I visit mountains once per year with my car. On average quite often in my area.
