A VW Golf TDI gets frozen in ice. Will it start?

Yesterday’s diesels had trouble starting in the cold. But Volkswagen TDI Clean Diesels are different. With advanced direct-injection technology, they’re designed to start reliably when the thermometer drops. To prove it, we’re putting a 2010 Golf TDI into a giant freezer to simulate the temperatures you’d find in the world’s coldest city, Yakutsk, Siberia.

A coffee filter shows how clean Clean Diesel is.

Diesels have a reputation for being dirty. But the advanced technology in Volkswagen TDI clean diesels makes that a thing of the past. To demonstrate just how clean clean diesel really is, we test the new Volkswagen Touareg TDI against a traditional diesel. Can TDI clean diesel technology really reduce sooty emissions by 95%? The proof is in the coffee filters.
