Tesla Counters Top Gear's Claims & DOA Honda/Acura NSX
One memorable scene had Clarkson and the Top Gear crew pushing their first Roadster (they had two for testing) into the garage after apparently running out of juice. Or did they? According to Rachel Konrad, Senior Communications Manager at Tesla Motors, the car was most definitely not out of juice

The charging numbers were clearly exaggerated by Top Gear. Not sure about the garage thing, but even a 20% charge after 50 miles doesn't add up to a range of 200 miles. Seems like a lot of spin on both sides. Yes, Top Gear seem to have over-dramatized a few things, but most of their points are still pretty valid, in my opinion. Also 3.5 hours is still 3.49 hours more than it takes me to fill the tank on my car. A trip to LA is still out.

The other stuff is good to hear, but this sounds like total BS. Every EE worth a damn knows that you calculate the maximum current that you think will ever go through the circuit in the very worst possible case, and then you make your fuse double that ( ... )

And I'm not familiar with fuses.. that's interesting. That's basically like Tesla admitting they screwed up or are lying..
And yes an ultracap would be cool. How much faster would the car charge?

The only ways I see out are A) "Yes, we admit we didn't do the math and chose the wrong fuse. Fixed now." or B) it turns out that the fuse wasn't in the regenerative braking system. In which case they still have some explaining to do.
And yes an ultracap would be cool. How much faster would the car charge?Well, I wouldn't advocate using one as the main energy storage for the car. So there'd be no effect on charging time - that's dependent on chemical reactions in the battery, and the addition of an ultracap won't change those ( ... )

Still, the energy calculations should hold.
