Video: Jeremy Clarkson says Porsche 911 Turbo cleans LA's air

The video meant to be presented here is no longer available. Sorry for the inconvenience.

In the video above, Jeremy Clarkson, host of Top Gear, says the Porsche 911 Turbo cleans the air in polluted cities like LA. While, I have seen concept cars that can clean the air, I seriously doubt any existing car, especially the Porsche 911 Turbo, emits exhaust that is cleaner than air, even air in the most polluted cities. Here is exactly what Clarkson says:

When you drive this car through a really polluted city; Los Angeles, Calcutta, Harrogate(?), something like that; the gas coming out of the exhaust pipe is less toxic than the air going into the engine. And I am not joking, that's true. This then is like a small, efficient, easy to use vacuum cleaner. They should have called it the Porsche Dyson.

So, here's the question for a Sunday afternoon. What do you think? Is he wrong or does he have a definition of toxic that I don't understand?
