Going by what Jeremy Clarkson says (the reviewer who did the Tesla piece, for those that don't know), I'd think every car manufacturer would have claims against Top Gear. Most BMW's are described as rubbish. Audi's are for male-roosters. French cars are all crap. Porsche 911's were designed by Hitler, nor have they changed since 1938. Most American cars are dreadful. Ford Mustang's have the rear suspension of an ox cart (true, that...). The old Saab 9-5 had enough torque to change the rotation of the earth. And on, and on, and on. It's what Top Gear does. The Tesla Roadster wasn't singled out.
Top Gear is 20% car information and 80% entertainment. Jeremy's work in particular is overwrought with irony and sarcasm. That's the way he is, and I and many others love it.
The piece on Tesla did nothing more than point out the "range anxiety" problem. That shouldn't have been unexpected. The fact is, Top Gear presents cars in a way that many people (350 million or so?) find entertaining. IIRC, they did have a few positive things to say about the Tesla while it was working. The handling and acceleration was good. But they did point out that after a thrashing on the track, they ran out of juice after ~55 miles. And then just like the battery-powered R/C cars of my youth, you're stuck inside for the next X-hours while the thing charges back up. That is the #1 problem with electric cars, and Top Gear did nothing more than to play on that issue.
Bottom line, if Tesla had wanted a rainbows-and-unicorns review of the Roadster, they should have called MotorWeek.
