Time to fire up the TiVo. Tomorrow night, the Science Channel will debut a new episode of "How It's Made" that features the Audi TDI clean diesel engine range. What's the big deal, haven't diesels been around since the death of the dinosaurs? Well, sorta. While they still share the same basic architecture that Rudolph Diesel invented all those years ago, today's modern diesel powerplants are a far cry from the old smoke belching, shake-themselves-to-pieces lumps of yore.
The actual engine featured in the segment will be Audi's 3.0-liter TDI V6, which puts out 225 horsepower and a whopping 406 lb-ft of torque in the engine bay of the 2009 Q7 TDI while still maintaining class-leading fuel efficiency. Soon the German automaker will introduce its second clean diesel-powered vehicle here in the States in the form of the 2010 A3 TDI, which you can read about here.
Anyone interested in what goes into building a modern diesel powerplant will want to tune in to the Science Channel at 9pm (Eastern and Pacific). Click past the jump for the press release.
NOTE: BMW North America contacted us to correct the statement that the Audi Q7 TDI offers class-leading fuel efficiency. With an EPA mpg rating of 17 city/25 highway, the Q7 TDI is bested by the BMW X5 xDrive35d at 19 city/26 highway. The BMW's 3.0-liter diesel is also more powerful with 265 hp and 425 lb-ft of torque.
