Thank you Mr. Wilson and tpl for explanation and clarification.
From the Cypress Bowl Rd. exit to the ski hill parking lot you bring the 2000kg car up by about 600 meters, for which you need about 12MJ of extra energy. If you want to make the ascent in 10 minutes the extra power required is about 20KW in addition to the power requirement to go on a flat road, which should be about 30KW. Taking the loss in the generator, power electronics and motor, 53KW is barely enough to accomplish the task.
Actually I am hoping that my assumption will be proven wrong. Then, serial ICE>electric motor design with a sub-100HP ICE will be the standard motivational method for every day car with, perhaps, much smaller, lighter and cheaper battery buffer. EV range can be as short as 20km. Still it means a tremendous saving of fossil fuel use.
