There's a video too, from http://www.insideline.com/nissan/leaf/2011/2011-nissan-leaf-first-drive.html

The highlights below:

This is a full five-seater with a conspicuously large trunk. You sit a little higher than you might expect because there are 48 lithium-ion battery modules under the floor, but that's no bad thing. The cabin is spacious, airy and promising. The electronic dashboard works particularly well, using state-of-the-art graphics to present almost certainly more information than you will ever need, a way to reassure you that the Leaf is not going to run out of electrons without giving fair warning first. Nissan calls this "range anxiety" and, as we shall see, it's an understandable affliction.

The Fun-To-Drive Quotient
You ease the Leaf through the first corner and see a long straightaway appear, so naturally you nail the throttle to the floor, expecting acceleration of the barely discernible variety. But that's not what you get.

Because maximum torque is always and instantly available, the Leaf jumps forward with sufficient alacrity to make you wonder if it should not be renamed "Leap," a word that describes both its throttle response and game-changing technology with equal precision. Nissan reckons this electric vehicle's midrange punch is on a par with a sedan powered by a 2.5-liter V6 (probably it really means a Nissan Altima 2.5 with its inline-4, but whatever), and we'd not argue with that.

The 2011 Nissan Leaf also has a party piece, a feature quite incidental to the reason it exists but likely to add considerably to its appeal. And that is the location of the batteries under the middle of the car instead of in the trunk. Because the Leaf represents a clean-sheet design, Nissan created a platform that centralizes the weight of its heaviest components — the batteries — within the span of the wheelbase. And this bit of physics when combined with a very low center of gravity makes the Leaf very responsive to directional changes.

That is to say, all this makes the Leaf implausibly good fun to drive. OK, this is no Porsche Cayman, but when your expectations on the dynamic front are precisely zero, anything comes as a pleasant surprise, so the Leaf's ability to corner both flat and fast adds up to considerably more.

Reality Bites

And now we must let the cold light of day flood into this rosy picture. Because while the Nissan Leaf might be surprisingly good to drive, what matters — and what, ultimately, will determine its success or failure — is what it is like to live with.
The bottom line is that currently the 2011 Nissan Leaf has a range of just 100 miles, and that's worked out to the U.S. LA-4 driving cycle (the original EPA city driving cycle, before the current FTP cycle was instituted), and this means that even Nissan admits that the car's owners are going to struggle to achieve it. Moreover, the Leaf will top 90 mph, but it won't travel 100 miles at that sort of speed — 60 miles is more like it, we're told. So this confirms what we all know about electric cars, which is that they are meant for city streets, not interstate freeways.

It's also useful to remember that it takes eight hours to recharge a Leaf with an industrial-type 220-volt hookup, though you can get an 80 percent recharge in 30 minutes from a specialized high-energy recharge station.

The math still adds up for most people, since we live in cities. And, as we're constantly reminded, 80 percent of us cover less than 60 miles daily. So Nissan considers the Leaf to be an eminently viable proposition as a result.

Besides, the Leaf also does much to minimize any residual range anxiety that you might have. Its navigation system is hooked up to a global database, so as the charging infrastructure expands, the nav will automatically update and always be ready to take you to the nearest power supply. Over and above that, the car's operational radius is displayed on the nav screen, so if you program a destination that's beyond the circumference, the nav will not be shy about letting you know.

You can even talk to the 2011 Nissan Leaf through your mobile phone, telling it, for instance, to warm up its interior on a cold morning while it's still parked and charging in your garage, saving you battery life and a cold backside. Once it's charged, it will send you a text saying it's hot to trot.

The Cost of Being Green
Of course what you pay for the electricity and how clean it really is depends on prices that change and the kind of power station in which the electricity was generated, but it's still safe to say that the Nissan Leaf's cost per mile traveled is a small fraction of what it would be for a car of the same size that burns gasoline.

But there's another saving, too. Where a conventional car needs an annual checkup, the Nissan Leaf effectively looks after itself. In fact, Nissan says the only routine maintenance required at the dealer will be the renewal of brake pads, and since the Leaf's regenerative braking system minimizes pad wear, it could be some years before the car needs any maintenance at all.

In around five years, however, the Leaf's lithium-ion batteries will only take around 80 percent of their original charge, so you might feel inclined to change them, not least because the replacements will almost certainly have far greater range than the old ones even when they were new. Indeed Nissan says it has targeted a cruising range of 300-350 miles for the Leaf, though the company admits the technology that will achieve it does not currently exist.

Will This Car Succeed?
It's the million-dollar question — or multibillion-dollar question, if you're Nissan. Certainly the 2011 Nissan Leaf will prove an outstandingly able device for delivering urban mobility. The immediacy of its motor response coupled with its unforeseen dynamic nimbleness will make light work of heavy traffic and there really is very little for the range-anxious to fear so long as you remember to put the plug in the wall at night.

But as with other EVs we've driven, the 2011 Nissan Leaf will have to wait for the rest of the world to catch up with it. Only when it's possible to recharge your Leaf with another hundred miles of power in the time it takes to knock back a coffee will this car's true potential be unleashed. And only when batteries are capable of sustaining the Leaf for more than 300 miles or more will this and other EVs stand a chance of prevailing over the conventional automobile with an internal-combustion engine that has served us so well and for so long.

Don't hold your breath waiting for that to happen, though. Even in 2050, up to half the cars on our roads will still be powered by internal-combustion engines, Nissan says. So while the 2011 Nissan Leaf is undoubtedly the start of something big, it seems the finish is so far away that few of us reading this today will even be here to see it.

Lifetime brakes? If the brakes are barely used is that good for the caliper seals and fluid?

This thing sounds great if it wasn't for the range limit. And what if you live in an apartment? I used to plug my space heater into the hallway outlet, that would be nice for charging your car too :)

I think we are headed towards electric vehicles. It's the cleanest and most efficient. The one thing people haven't said about hydrogen cars is that it assumes that producing and shipping hydrogen is easy which it's not. The same goes for ethanol. This car is the sign of things to come. I wouldn't buy it but once they figure out how to have long ranges or fast fill ups, electric cars will be a no brainer. Sure you'll still have gasoline or diesels but once it's economical to switch over even trucks or cargo ships may switch. Maybe cargo ships will even have a mini-nuke power plant like subs.
