Tesla isn't making profits, any plus from Roadster sales goes into financing the Model S. I'd think this *is* within the purpose of the tax breaks, since the Model S is a more affordable EV, and since it helps Tesla to reach more customers with EVs. At least, it makes a lot of sense to me, even more than reducing the price of the Roadster would.
Elon Musk publicly says that the Tesla Roadster and Joint Venture business units are profitable, today, and the losses are due to Model S development (which is funded by the government loans).
As you say, the Model S should be the more affordable EV (much as the Leaf is). If the base price of the Nissan Leaf is US$32k in USA, and US$55k here, what is that going to do to the Model S price?
A Prius costs about US$37k here (including full tax, less about US$1.2k green council incentives for hybrids).
My issue is not with Tesla (or anyone) making profits. My issue is that the tax incentive is there in order to bring the prices of EVs down to an affordable level to promote their adoption. By jacking up the prices, the manufacturers aren't helping and I suspect it will just result in the incentives being reduced/removed. Without the incentive, the Model S is going to have to sell for >US$110k, and at that price it will not be a success here.
My goal is simple. Get as many EVs on and ICEs off the road in Hong Kong, and create a sustainable EV economy - as quickly as possible.
EVs today cost more than their ICE counterparts. But the tax incentives can balance that out - and with servicing, gas and road tax benefits it becomes a no-brainer decision (on a cost basis). A Nissan Leaf should be salable in HK (with tax incentives) for the same price as a Prius. Hong Kong is in a unique position here, and it will be a shame to see it wasted. The tax incentive in HK is set to expire in April 2014.
