Let's say, just for the sake of argument, that a seven-passenger, diesel-fueled luxury SUV like the Audi Q7 consumes an average of 7.2 liters of fuel per 100 kilometers (32.7 miles per gallon U.S.). Would this be considered a green machine? Well, we'd go with "yes" and here's why: some drivers simply must have seating for seven. So, which vehicles seat a driver and six others, perform admirably, emit a reasonable a 189 grams of CO2 per kilometer and return 32.7 mpg? Audi's new 3.0-liter V6 TDI-equipped Q7 SUV does.
The Q7 3.0 TDI cranks out a paltry 204 horsepower, but with 332 pound-feet of torque on tap, this new mill propels the luxury SUV to 60 miles per hour in 9.1 seconds. That's not exactly sports car territory but, as we mentioned above, this Audi focuses on being green. With that in mind, Audi equipped the TDI-powered Q7 with a eight-speed tiptronic transmission and extensively reworked the engine internals to reduce weight and minimize friction. Audi's labor paid off, resulting in a finished product that is more efficient than all of its direct competitors.
On a side note, many of our astute readers will quickly point out that the Q7 is already offered with an optional 3.0-liter TDI mill. In fact, you can order Audi's Q7 equipped with one right now, but that mill, unlike the Euro V-compliant one described above, only returns a combined 20 mpg.
