The Flawed Soul of a New Machine

It bears repeating, and shouting from the mountaintops, that Top Gear just may be the best show on television, let alone the best car show by orders of magnitude. Not only is it on BBC America several times a week, but it is also one of the most heavily downloaded shows in the world. For those of us in the U.S., downloading is the only way to see the current series, as BBC America is currently showing episodes that are one or more series in the past.

[If you have any interest in seeing the most recent episodes, let me know. I, um, might be able to suggest ways to find the new shows.]

The biggest delight of Top Gear is usually the sheer lunacy of the contests the three witty hosts engage in, the way only clever Englishmen can do it. The most recent Top Gear, though, broadcast last Sunday night, was journalistically unusually hard hitting. Top Gear conducted what must be among the very first full tests of the much-celebrated Tesla electric sports car. The Tesla, based upon a modified Lotus Elise chassis and built here in the Bay Area, has generated (sorry for the pun) a lot of publicity in the several years of its gestation. Hollywood celebrities have enthusiastically plunked down the requisite $100,000 to be the first on their blocks to have one.

The Tesla, for all of its high wattage publicity (pun again, sorry), has not had a smooth trip to market. The car has undergone a number of developmental problems. The most significant design issue has been with the transmission. The original two speed gearbox proved to be unable to handle the considerable torque of the electric motor, so production Teslas leave the showroom with a single speed gearbox (albeit connected to a motor that can spin upwards of 13,000 rpm). Rumors have also dogged the Tesla program that the car's range was nowhere near the 200 miles advertised.

The Top Gear boys put the car to a proper test, the first I can recall seeing anywhere, print or otherwise. The car proved to be extremely quick, dusting the Elise in a sprint. However, the tradeoff in the considerable extra weight of the batteries (and high-efficiency, non-sporting tires) revealed itself as the Tesla slewed about the handling course. More significantly, after some enthusiastic driving, the car came to a dead halt ... in 55 miles. While that car underwent its 12 hour charge, they brought out another one to continue the test. It stopped with an overheating motor within a few minutes. After charging, the first car was brought back out, whereupon it promptly suffered a brake failure.

As a new car maker on the world stage, trying to forge ahead with new technology amid plenty of politically correct hype, the Top Gear review was devastating. Not by anything the hosts said, but by the way the car performed under real, albeit heavy, use. The car exhibited a lot of failure for $100,000.

Later, the show demonstrated a better way forward. One of the hosts made a rare trip to Los Angeles to sample the Honda FCX-Clarity, a remarkable car in very limited release. Also an electric car, it is powered not by heavy and environmentally disastrous batteries, but by a fuel cell powered by compressed hydrogen. With a range of at least 200 miles, emissions consisting only of water, and refueling taking only the usual couple of minutes, the host made the salient point that cars like the Clarity are likely the best bet for the future because they are the most like the present. No overnight charging, no hazardous and heavy batteries, and quick fill-ups make for a consumer-friendly product. If Honda can convince energy companies to enlarge the distribution chain for compressed hydrogen, a real paradigm shift may take hold in the automotive world, one that even car enthusiasts could embrace.

That is all very interesting to your blogees (is that the right term for those who read your blog?), but you should try and convince your policy makers, many of which are still convinced electric cars will be the way of the future. If Todd rises to the US Congress quickly enough, perhaps he can pass the great idea along!
