Sorry I didn't have time for a fuller reply last night. Currently on my third Ford in 11 years, the one thing I really don't want to be without is heated windscreen. Hoped that PTC Heater would be next best thing. The brochure for the Suzuki Swace self-charging hybrid, which I'm sure you all know is a Toyota Corolla with different badges, says it does have PTC Heater. My thoughts about not enough battery power to run it, was to think the engine would cut in to provide extra electrical power. If a rebadged Corolla has it, I had hoped a Lexus would.
