What did the range reduce to, and how much did the regenerative braking add?

>Model S recently completed a trip from San Diego to Vancouver using only Tesla’s new Supercharger network, which provide a 200 mile (320 km) charge in 30 minutes
30 minutes is slow by gas station standards. Internal combustion engines use more gas when hard-driven too, but 70%? We also know that batteries aren't as efficient at freezing temps, so canadian drivers would have to consider that. There are still many hurdles to overcome for EV's but credit has to be given to Elon Musk's efforts. It's a beautiful machine and i see more of them here in Montreal.
The 4WD option may not be worth pursuing. I assume that the Tesla is a FWD. Adding a drive shaft and rear axle, or two motors to the rear wheels would bring the weight up to 5000 pounds. Ouch. That's a killer. The very low center of gravity and present weight are more than enough to ensure a good grip.
It's the batteries. Ones that can handle the cold, higher capacity, lighter weight, and faster charge times are the the main challenges that i can think of at the moment.

A lot of P85s in Vancouver these days. Luckily, I witnessed one driving right beside an Aston Martin a few days ago. That's a great comparison of form and function. I saw surprisingly little difference between the two as the Tesla pulled out in front and the DB9 followed.
I also had the opportunity to look one over and sit in it. I can say that the interiors of the established luxury performance cars are better executed and the seats themselves, more supportive. Maybe Tesla will catch up in this department, as they should for the price.
From the driver's position my only complaint was that the 17" display (a 17" touch-screen turned on its end and inserted into the dashboard) sits a little too close to the driver's right knee at the bottom. This would be a serious distraction on a longish trip. They should, at least, put a little padding around that area, either in the form of a stitched leather wrap-around or sculpted insert. Ideally, they could shape the screen so it becomes slightly narrower at the bottom.
One other observation: there is something wrong with the nose/grill of the car. It looks slightly cheap and a little bit like an after-thought. They need to get someone really talented to redesign it. This part of the car should be iconic and instill at least some emotion...

Love to rent one anyplace that has recharging IE static plug in or Wi Fi style mode, any state in US.

Would be perfect for me I only commute 5.6 miles to my shop one way, leaving me with a nice hot battery for proper thrashing both ways, and they just opened a tesla dealership 200 yards from my house, might come in handy for warranty.

What a lot of people seem to forget, is that electric cars have "efficiency" ratings just as gasoline cars have MPG. If efficiency is really your thing, then you should look into mi/kWhr ratings.
What you will find is that lugging around an excessively large 85kWhr pack is detrimental to efficiency. If you want efficiency, AND you want a Tesla, then the 60 is the way to go, but even that thing is total over-kill for 95% of drivers.
Take Jay (above) for example, claiming his 5.6 mile commute would be perfect for a Tesla. I'd like to point out that if you have a 5.6 mile commute, an EV with a 200-300 mile range is total over-kill. And that's over-kill that you, the customer are paying for. So if I were Jay's buddy, and he asked me which car would be the most efficient for his daily commute, I sure wouldn't point him in the direction of a 300-mile range EV. Heck... with such a small commute, a golf-cart would easily get him to work and back with juice to spare. I'd probably point him int he direction of some less-expensive, lighter-weight, and smaller battery-pack EV's that have a higher mi/kWhr rating. (like the Leaf, Focus, Rav4, or for super-efficiency: the Chevy Spark) All of these EV's best the tesla for efficiency.
I encourage anyone who is looking into getting an EV to seriously question just how much "range" you actually need on a daily basis. Chances are, 50 miles is all you need. Anything more and you are paying for it in price and weight.
I Love the Tesla. I just don't love the idea of paying for and carrying around an excessively large battery pack.

"A motor of 150 bhp , a smaller, lighter, cheaper battery would satisfy most people's needs and could perhaps even be affordable. Perhaps in time, Tesla will perceive a mass market and make a "people's electric car."

There already is such a car like that. It is called the Nissan Leaf. nissan sells quite a few vehicles like that. Personally, I think they are what most people want, and they are nice vehicles from what I have heard, but personally, I would not be caught dead in one.
As an owner of a modified Awd Audi A6 twin turbo, a modified V70r and a heavily modified Volvo 940t (2jz swap) you can tell, I love performance vehicles, and I love what Tesla is doing. Mr Musk has his finger on the pulse of how you bring new technology to the masses. You do so by making sexy, exciting, appealing vehicles that beat the incumbent technologies at their own game; namely acceleration and handling and safety. The tesla does all 3, out-accelerating nearly all 4 doors in its class, being the safest car ever tested and also handling well to boot.
He's designing and building vehicles using very expensive technology and building it to stand up to world class auto makers, beating them at their own game. The average tesla owner cares little about making an environmental statement or what they "need". These people moved far past needs, as they're paying $100+k US for a vehicle! Once again, you sell the high tech toys to the rich and let them pay for your R&D, then after all the bugs are worked out of the technology, you build a detuned, cheaper version for the masses.

The current line of Tesla cars are place-holders. They are not viable until next-generation battery technology come on-line. Even then, the vehicles will primarily be powered by natural-gas...once removed.

The whine comes from the motors rather than from "generators".
