First, kudos on getting something which is at least partially EV, although I think Chevy could have done way better than a 40 mile electric only range, and even though I still think the concept of having a gas generator is a unnecessary kludge used to basically compensate for some horrible design decisions.
Second, you do realize the Volt could have had probably 200 to 300 miles of range if they ditched the heavy gas engine and made it more aerodynamic? Yes, I agree range totally matters with EVs but why the f are we totally ignoring a path to get more range which is virtually free-namely making these vehicles as aerodynamic as possible, preferably like
this? This vehicle uses less than 0.1 kW-hr to cover 1 km. If it had the same size battery as the Volt, it would have a range of close to 200 km. Ditch the engine and put in a bigger battery, you're easily up to 500 miles. So we can make EVs with better than your desired range of 350 miles right now. Other than Tesla, nobody is even attempting to make them. It may have to do with car makers wanting to get the life cycle out of all the tooling they spent on ICE vehicles. I understand this part from a business perspective, but this also means they're intentionally crippling any EVs they make, and/or grudgingly making them, so they don't get much market penetration. If we made EVs with 300+ mile range and they sold for the same price or less as ICE cars (which would be the case if they were mass-produced), almost nobody would want ICE vehicles any more.
Third, as for your trip to NYC, two things here to remember. One is that driving/parking in NYC is almost always an expensive hassle, even for the locals, and pretty much not worth it. Two is that we have great train service into the city for most of the day from many locations. Yes, the price for the charger was ridiculous, but charging infrastructure will get better as more people own EVs. That said, if you're coming into NYC, your best bet is to park outside the city at the rail station which is closest to the city along your route. Or it needn't even be the closest. When the traffic starts getting heavy, then it means you're close enough to the city that getting in any further by car will be a nightmare. So park near a train station, enjoy the 15 to 30 minute ride in (compared to probably an hour by car). That's the best way to get into the city. I'm about 10 miles from midtown. It pretty much always takes at least an hour to get into Manhattan by car from me, often longer, except maybe between 9 PM and 5 AM. Subway and bus usually takes about 40 minutes, and the bus is no speed demon. This is why relatively few people own cars or drive in NYC. It's not worth it. My travel times by bike, even in eastern Queens which has less congestion than Manhattan, usually rival typical auto travel times. Bottom line, unless you're bringing in more stuff than you can carry on a train, don't drive all the way in. Not worth the aggravation. NYC is easily the most unpleasant place to drive in the US, and possibly on the entire planet.
This will probably make the whole range thing entirely moot. It's already being tested in Formula E racing. Electric trains get their power on the fly, so why not cars?
