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?
