The main issue with the emissions was on startup with the exhaust catalyst not while driving. Quantum Technologies and Fisker Automotive at the time ran into some "business" issues and that caused much of the finger pointing during the launch (HCU among others). CARB, EPA etc had little to do with the behavior currently implemented on the vehicle.I thought I read on this forum that the reason for the change was a compromise in the ICE behavior with the state of California to make it pass emissions.
When you are driving in range sustain mode you are essentially doing the same thing (this is actually more efficient due to no propulsion load). Keeping the SOC high on the battery allows for a greater performance envelope and you essentially charge 3+x faster than plugging in. Point is it is up to the owner to decide if they would like to plug in or charge off the ICE. For me, many times its easier to just charge off the ICE and fill up rather than wait 5-14 hours for a full charge from an outlet. Plugging in at a public charge station is pretty useless unless you plan on spending most of the day somewhere.It seems to me that using an internal combustion engine to charge your car battery is very inefficient compared to a large utility power-plant. Why not just wait to plugin and not diminish your MPG? Just using logic, am I wrong?
Will try to answer some of these questions.I have to agree with Steven;"It seems to me that using an internal combustion engine to charge your car battery is very inefficient compared to a large utility power-plant. Why not just wait to plugin and not diminish your MPG?"
I recently completed a 4000 mile trip in my Karma. Electrical outlets were not commonly available at hotels/motels. At friends places I visited, of course I charged the battery. When I couldn't charge the Karma, I just cruised along on the ICE without any problem, stopping for gas when necessary. BTW, the 10 gallon tank exceeds my bladder range. Several days on the month long trip, my electrical range was zero. Overall, I averaged 31.13 mpg.
Had my Valentine One radar detector confiscated in Canada plus a $175 dollar fine for having one. Picked up a new one in NJ.
Performance may be improved with the Power Source option, but how much? Any 0-60mph times/100mph times? I don't remember any time on the trip that I needed added performance.
