While the base 3.0-liter supercharged V-6's 280 horsepower and the S line's more sharply-tuned 333 horsepower (from the same basic engine) deliver more serious sport, the 3.0-liter turbocharged diesel V-6, newly reengineered this year, is just about as much fun--and considerably more fuel efficient on the highway.
The gasoline versions of the Q7 rate 16 mpg city and 22 mpg highway, while the TDI diesel scores a more impressive 19 mpg city and 28 mpg highway. No large crossover is going to win a green-car gold medal, but among the three choices, the diesel is the clear winner.
Conclusion
The 2013 Audi Q7 TDI diesel is the best pick for gas mileage, and there's no real downside to performance.
