How I Fell in Love with the Roadster

Don Cox is a Professor of Electrical and the Harald Trap Friis chair at Stanford University. He 25 years at Bell Laboratories and developing revolutionary technology for is now referred to as cellular phones. He has on the board or as an officer of several Valley public companies and on technical advisory boards of others. In this week’s entry, Don explains why he wanted to be the first customers to receive a Roadster. (Don, pictured with his wife, Mary, out the Tesla Roadster.)

My wife, and I were invited to be a “guest on the Tesla Motors website. is a big honor for us. It is an easy task of our high regard for the Tesla and the people at Tesla Motors.

We had a long-standing interest in electric because of their potential to help reduce our country’s on foreign oil and to save our environment pollution emitted by cars use internal combustion engines. We you might be interested in our experiences and in becoming Signature One Hundred the group that has reserved the Tesla Roadsters to come off the line. Our story might be “How we fell in love the Tesla Roadster and Tesla

The first time that our son his wife, Nagin, and I saw and rode in a beautiful Tesla Roadster was at the Big in Santa Monica, Calif. on 19. What an exciting experience for us!

There were several that we needed to resolve “signing up” as a Signature One Hundred The first issue was whether and I could get into and sit in the small – we are both 6’4” tall. My was first, and it was surprisingly easy. in the driver’s seat was snug but

The task was even easier for who is many years younger.

The of whether Tesla Motors build a working car was resolved by the cars circle around the big party all night, and by riding in a car as it the hanger and catapulted its occupants to speed on the tarmac outside. The was too short and too exciting to note how we actually went on the speedometer!

We many Tesla Motors about the design details of the All the engineers displayed high and willingness to discuss the car and design made. Of course, we scrutinized the battery pack in detail. more than 6,000 cells is an economical and reliable to this key electric car component.

Motors has taken a careful to temperature management by circulating liquid through the battery and by continuously monitoring temperature, voltage, and currents with a The Li-ion cells provide the energy- and power-efficient battery at this time.

The 3-phase, induction motor is the simplest and robust motor that can be It has only one moving part and no The Tesla Roadster has a highly and rugged design, which be very reliable as well as exceptional torque over the speed range. The high-efficiency controller is conservatively designed The aluminum chassis and carbon body also appear to be designed.

The mechanical integration of the electrical with the body, suspension and has been done effectively.

questions were: Do they the need for extensive testing of the and can they manufacture the cars in There are several electric car floating around with testing plans and no clear to production. The Tesla Motors staff outlined ongoing and plans for a comprehensive overall program to ferret out needed improvements.

Talking to Tesla manufacturing managers and engineers the outline of a well-thought-out plan to the first 100 cars and also a for continuing production beyond the 100.

Another question we into was the economic viability of Motors, the company. We convinced that Tesla Motors has funding that should continuing design, testing, and activities. The clear popularity we signed on leads one to believe others see the value in the Tesla too, so there appears to be a for the car.

At the end of the Santa Monica we were very impressed the prototype cars, with the Motors engineers, and with the overall. But we were still “on the about “taking the plunge” Signature One Hundred membership.

The deciding input was provided at a at an Electric Auto Association meeting in Palo Alto, on August 5. J.B. Straubel, Technical Officer at Tesla gave an interesting and comprehensive of the Tesla Roadster design, the tradeoffs, some progress of and many issues for electric He skillfully fielded a myriad of from the large EV crowd.

His of EV issues, design tradeoffs, and was impressive.

A Roadster prototype was in the parking lot after the talk. It was very positive Tesla event. On our way home, Mary that this was the first technical presentation she had heard in a time in which the speaker like he knew what he was about!

She thought we should the Signature One Hundred group at We did the following week.

How did we become enough to attend the Tesla event in Santa Monica? and Nagin leased a General EV-1 for several years GM “pried it away from During that time let us use it several weeks. (Yes, it was from Los Angeles to Stanford and They became very to that car and Mary and I did too.

We many students and others for and let quite a few of them drive it. loved the EV-1 and many how they could get one – too bad none was by then. It was a great joy for us to drive the whenever we could. It was not just a it was a useful car. Earl with it for several years up to 30 each way on freeways, and Mary it to work 10 miles each way it was “her turn” with the

Plugging it in at night and unplugging it in the was much easier than to gas stations.

Of course, a major in the EV-1 was the batteries available at time, first lead and later nickel-metal hydride. It was a sad day GM took the car back and crushed it in the along with all the others. then followed closely the electric car projects, and I looked at of them too.

None our careful scrutiny and none to have a path forward to a significant number of cars. We did not to have an “orphan” car. along came the announcement of the Motors event and we were to secure invitations to it. As they “the rest is history.”

We visited the Tesla Motors San Calif. headquarters since the Signature 100 and toured the engineering and testing areas. One tour by Joyce, vice president of at Tesla Motors, and J.B. additional comprehensive information on testing, and manufacturing the Tesla Their testing at all levels, components to subassemblies to complete is very thorough.

The computer-controlled dynamometer they themselves for testing the motor and shows a high degree of and resourcefulness.

A second tour another ride in a Roadster and discussions with several Motors people. They are and improving designs where like any highly competent does when developing a new product. In each interaction, we more positively impressed the design and manufacturing team and the of the company in general. Our discussions of choices have always excellent knowledge of the alternatives and exercise of good engineering in making design decisions.

In cases we might have different design alternatives, but the Motors choices appear to be the ones for the company’s goals.

the Tesla Roadster be a perfect No complex machine is ever but it appears to us that the Tesla will be a truly great without any serious flaws.

It was a lot of for us – we are not among the super rich. we did not feel that we could to pass up the opportunity to own such a and unique car.

It may sound we have been “brain by Tesla Motors, but I am certain is not the case. Mary and I are conservative, technical people who have many years assessing promises and hype. I spent 25 in industry, working at Bell and Bellcore and involved in developing technology for what is now referred to as phones”. I am now a Professor of Electrical at Stanford. I have been on the or served as an officer of several Valley public companies and and I am or have been on technical boards of several others.

Mary has been a chemistry for more than 30 years in New and California. Between the two of us, we have a lot of in the basic technologies in electric in launching new technologies, and in starting and companies.

We have done diligent investigation of Tesla the car, the people, and the company. We are that they have an collection of engineers and other who have designed an outstanding car and produce many of them year. We are waiting enthusiastically to ours and are looking forward to Motors providing other sports cars, practical sedans, economy cars, and all of electric vehicles that need.
