Turbo is really retro. I do want a voice analyzer button to see if my passenger is lying. I can't really look them in the eye for very long when I'm driving. A HV should have a burst button. BMW in their vision concept car has a 80 hp electric motor that can be boosted for 10 seconds to 130, ofcouse the rear axle is driven by a small turbo diesel. I really want an after burner switch on my next vehicle.
I'm going back to PWR - pretty sure that at most speeds over 20mph, it's more efficient than ECO by staying in the RPM "sweet spot" when accellerating (rather than being below the sweet spot like I think ECO does).
