The Porsche Taycan is one of the least efficient EVs the EPA has ever tested
If you are going to make a serious Tesla rival (or a serious electric car, period), range needs to be high on your list. With that in mind, Porsche used an all new, specialized EV architecture for the Taycan, an 800-volt battery pack (as opposed to the normal 400) and other tweaks to make it go as far as possible on a single charge. And the end result? 201 miles of range and 69 MPGe. Or, to put it another way, 3 fewer miles of range and 5 fewer MPGe than Audi managed with a 400-volt battery stuck into a converted gas-engine platform, on a car that weighs nearly 1,000 pounds more than the Taycan. And even more significantly, that's nearly 200 fewer miles than the top spec Tesla Model S--a car that is nearly $60,000 less than the starting price of the Taycan Turbo that performed the test--and that's before you factor in Porsche's famously expensive option pricing. At the risk of stating the obvious, this is disastrous for the Taycan, and could sink its chance at luring away Tesla buyers.
Actually, let's be fair about this. The Taycan is not the least efficient production EV the EPA has ever tested. There are two that score lower than the Taycan: the 2001 Th!nk City Car (not a typo) and the 1999 GM EV-1. Also, the 2000 Toyota RAV4 EV, converted from a now-20 year old car with now-20 year old battery technology, only scored 3 more MPGe than the brand-new, purpose-built, top of the line, $152,000 Porsche electric car. Oh. When I say it like that it sounds even worse.
Porsche, understandably, were horrified at the results, and got a fuel-economy testing organization called the AMCI to do their own tests. They achieved a combined 275 miles of range--but I personally would take that with a grain of salt until it can be confirmed by buyers.
When the Taycan came out, I thought it would be the first serious competitor to the Tesla Model S. As it turns out, though, I was wrong. The first serious competitor, it seems, is still yet to come. Maybe Audi will have better luck with this platform?
