So far we haven't found anyone in California or anywhere else with BOTH new mass-produced plug-in cars. Since my wife Rochelle Lefkowitz and I both work from home, we're not that typical. Still, as early adopters, it's a privilege to be an ecumenical plug-in household.

PHOTO: Rochelle Lefkowitz and Felix Kramer in front of their Redwood City, CA home with their personal plug-in fleet. When their 2004 Prius was converted in 2006, Felix became the world's first consumer owner of a PHEV. (That vehicle, currently equipped with a Hymotion battery pack, will soon go to an institution or a new owner, leaving them with "only" two plug-in cars.)

Which car is better? The real competition is the electric mile versus the fossil-fuel mile. But we enjoy competition among plug-in design solutions and carmaker races -- so here are our initial impressions and our first match-ups. In the spirit of encouraging wide discussion, we're posting this message broadly. See links at http://www.calcars.org/photos-plugins-arrive.html for the latest.

Since we got our Volt on Dec. 22 and our Leaf Jan. 24, I've felt like we've taken a time machine to the future. Since as the Founder of CalCars.org I've been doing little else but talk and evangelize about this for a decade, I thought I'd be ready for this moment. But now that it's really here, it's far better than I ever imagined!

Each car is like a 21st century space capsule, gliding silently through streets clogged with last-century vehicles. I was never so aware of the unique and ugly sounds from each gas-guzzler. At stop lights I even feel their low-frequency vibrations. As a driver of a Prius since 2004, which 60,000 miles ago in 2006 was converted to a plug-in hybrid, and as an occasional driver of a RAV4 EV or a Tesla Roadster, I've had glimpses of how this feels. But it's completely different to drive this way almost all the time!

Each car greets the driver with fun as its first feature. The instant torque of electric motors turns each of them into rocketships at low speeds, and easy lane-changers on the highway.

The driver's seat of the Volt feels like an airplane cockpit. It's a little intimidating at first, but reassuring after a few minutes of studying the controls and displays -- or just ignoring some for a while. The Leaf has a spare quality, and the simpler right-side panel is all about audio and climate.

Each car offers subtle clues about its fundamental character. The Volt puts a whole car between the front left electric door and the rear right gasoline door. Inside, the button to flip open the electric door stands out while I have to work to reach the gas-door release, giving the message, "You're not going to be using this very often." The Leaf's charging ports are under a giant door right in the center of the car's nose: "There's nothing going on in here but electricity."

Both cars have slipped up some on what's called "computer-human interface." We wish they'd listened to suggestions to put prototypes in the hands of Silicon Valley's usability experts last summer. For instance, the charging signals. Plug in the Volt and the indicator turns yellow (connected), then steady green (charging). Finally it flashes green (done). That's exactly the reverse of a user's expectations. The Leaf, with a longer charge time, starts out well, with three indicators that illuminate in succession as the car reaches its charge. But 15 minutes after it's full, all the blue lights go off. My first morning, when I greeted the plugged-in car, I wondered, "what happened?" Both MyLink and MyLeaf, the phone apps that enable me to monitor and control charging and many other activities, need major overhauls and quicker refresh. (Since the Nissan app doesn't make Leaf all-caps, I've got permission to stop doing so….)

Each car's manual is full of important information -- far more than I got even in the superb orientations from Novato Chevy's Terry McCarter and North Bay Nissan's Victor Maldonado. But each is daunting, and, unsurprisingly, written defensively and sometimes in legalese. I downloaded them from http://www.chevrolet.com/assets/pdf/owners/manuals/2011/2011_chevrolet_volt_owners.pdf and http://www.nissan-techinfo.com/refgh0v/og/Leaf/2011-Nissan-Leaf.pdf. Alas, for a spare copy, pages designed to fit in a glove compartment don't print well on letter-sized paper. And while the Volt's Index listings are live links; the Leaf's aren't, though once I got inside its chapters I could click to navigate. Nissan and GM may be watching Hyundai, which turned its Equus manual into a downloadable App -- and included an IPad with the car.

We all know both cars will get better soon. All carmakers will learn from each other. (The savvy ones aren't relying on their customer service operations, but have budgeted for large teams to track down and analyze the tens of thousands of comments and suggestions strewn around online.) The automakers can quickly update some software features. One reason we leased the Volt instead of buying it is our expectation for future hardware improvements in Version 2. The Volt's big challenge is making the car a five-seater. Tomorrow, Nissan could promise to supply every Leaf with rear headrests that lower to the level of the top of the back seats. That will vastly improve the half-blocked rear window visibility. (We remove them and replace them when we have rear passengers.)

Rochelle's first comment was, "Hey, I love these cars!" (She and our son Josh, both shown at the CalCars.org "Plug-Ins Arrive" page, have been stalwart supporters.) She wishes both carmakers had personalized the mirrors so she doesn't have to reset them every time she gets in after I've driven it. Otherwise, she's happy to just be able to get into each vehicle, push the on-button and drive it like any other car. She says it was a bigger adjustment to switch from a 1997 Camry to a 2007 Camry Hybrid than from that car to the Volt. She appreciates the rear cameras, especially important now that most safety-conscious cars come with thick side pillars.

Finally, the hard numbers. Our Leaf experience began with a fair test with an EPA-assigned 73-mile range: from the dealer in Petaluma to Redwood City. Driving at 65 MPH the whole way and not bothering to detour around the steep hill in San Francisco between the Golden Gate Bridge and US 101 (which cost about 4 miles of range), we finished a 74-mile trip comfortably with 14 miles to spare. The Leaf is reassuringly predictable: with 80-100 miles of juice, most of the time, we don't think about range; we just drive around and charge it at night. With 163 miles in four days, it may become our first-to-use car, with the Volt reserved for times we both drive and for distances.

The Volt is a more dramatic story. In 37 days, we've driven 2,281.0 miles and used 33.4 gallons. Does an average of 68.1 MPG sound disappointing? Not to us -- because it includes two round-trips to Lake Tahoe. Until now, no one could drive a plug-in car that route without refueling along the way: 225 miles including 8,000 feet of Sierra elevations. (Read about that record-setting first trip and see photos at http://evworld.com/article.cfm?storyid=1955.)

Here are details on the two Tahoe expeditions: First: 225.7 miles, 6.31 gallons at 35.8 MPG up, and 221.5 miles, 4.36 gallons at 50.8 MPG down. Second: 244.0 miles, 6.37 gallons at 38.1 MPG up, and 242.9 miles, 4.56 gallons at 53.2MPG down. (The second time we more than confirmed the numbers. We don't know why we got better results even on a longer route with an additional passenger and more cargo.)

We started each of the four drives with a full battery (boosting our average), then had major uphill drives (reducing MPG). The combined 43.2MPG is about what a second- or third-generation Prius gets on that route. (We expect the Gen2 Volt will improve its long-distance "charge-depleted" driving performance, which wasn't the top priority in GM's four-year push to meet the Volt's promised delivery date.) This proves a PHEV's best selling point: this one car can drive all-electric most of the time at its base location, then go any distance worry-free with good fuel economy, and again drive entirely electrically at its destination.

We've reached a sweet moment. Since 2005, CalCars has been trumpeting that plug-in hybrids (and extended range electric vehicles) get100+ MPG of gasoline (plus a penny a mile of electricity). GM didn't squawk when the Volt sticker said its MPG when using gasoline and electricity would range from 69-168 MPG for 30-75 mile trips. Now our real-world Volt experience confirms both our experience with conversions and our predictions for production vehicles. Many of our Bay Area trips in the Volt have exceeded the car's typical 35-40 mile all-electric range -- and we've used our portable charging connector at a destination only once. When we subtract out the two long trips, our local 1,346.9 miles on 11.8 gallons were at 114.1 MPG. (And CalCars colleague Ron Gremban driving his Volt Lynne McAllister showed 205 MPG after their first 468 miles, mostly in Marin County.) As they say, QED -- point proven!

Stay tuned for more specifics and comparisons in the future.

Felix,

Welcome to the forum. You will see a lot of very strong proponents of plug-ins here.

But then you will also get an earful from those who think the Volt is not necessarily the right answer to the question. Whatever the question is. :lol:

BTW, I've been getting your email digests for years, and also offer a welcome! :D

So do you have two EVSEs? It would be interesting if there were a Level 2 charger which could charge two cars. I'm thinking multiple plug in vehicle families will be common over the next ten years.

Thanks for the first welcoming messages; sorry I haven't been able to post here before--info overload, etc. As for the specific question, we have one Coulomb EVSE and (of course) two portable charging cords, one from each vehicle, which is plenty for our needs. In a perfect world, we'd have a 100-amp panel for two full level-2 charging systems. We don't have a separate meter; we do have a rooftop photovoltaic system with time-of-use metering.

WOW!! what a first post! thank you for contributions in getting EVs out to the masses. pushing the plug is the reason that Nissan saw fit to take the big gamble on the Leaf.

How do you charge all your cars? Is there more then one charger in the garage or do you charge day and night and charge off a solar grid ?
