    • Audi premium diesel performance, 2014 A8L TDI test numbers

      Audi is embracing diesels for the North American market which is great to see. Audi announced at last year's Los Angeles International Auto Show that they would bring four new diesel models to the American market for the 2014 model year one of which is the Audi A8. The diesel version of the A8 features a turbocharged 3.0 liter V6 with 240 horsepower and 406 pound-feet of torque. Not bad, but not as exciting of a diesel powerplant as the 313 horsepower and 479 pound-feet of torque turbo six cylinder in the Audi SQ5.

      Regardless, German manufacturers often ignore the US market regarding their diesel motors so it is nice to at least have an A8 diesel option. The car tested below is the A8L which mean long wheel base. The curb weight is a not very light 4,564 pounds. Some heft to move but the torquey V6 does well. 0-60 comes in 6.3 seconds and the 1/4 mile in 14.7@91.2.

      Not fast in this day and age but not slow either. The performance and the fuel economy (36 MPG highway) of the A8L show that diesels definitely make sense for the American market. So why are we not seeing more diesel motors? Who knows but hopefully the government and population start embracing the diesel.

      Comments:


      Acceleration:
      Any doubt the TDI version of the 2014 Audi A8L would be "sufficiently" powerful was erased in 2 seconds. Monstrous torque picks the nose of the car up and upshifts barely lessen the effect. There's a slight power dip at the top of each gear, but hardly. After accessing the super-quick shift program, it dropped a full second from the 0-60 time (shifts were noticeably quicker and a little harsh). Pretty neat feat of engineering here, but I really had little doubt that Audi hit the bull's-eye with the execution of its flagship sedan, diesel or otherwise.


      Braking:
      Brakes match the astonishing nature of the engine. Shortest stop was the fourth of five and it felt as if the A8L would match this short distance all day long. Straight, steady, firm pedal and zero fade or drama. Very good brakes.


      Handling:


      Slalom:
      Again, the abilities of this diesel limousine are amazing. There's more grip and agility here than most would ever imagine. Unlike previous A8Ls, however, I found a little more speed in "Auto" rather than "Dynamic" settings. While it still proved faster than previous A8Ls in Dynamic mode, it felt stiff and twitchy. Found even more pace in the more compliant Auto mode.


      Skid pad:
      Here, the stiffer-legged Dynamic mode paid dividends, but just barely. ESC allows a modest slip angle that can be maintained, easily choosing between under- and oversteer with the throttle. Superb balance and control. In both tests and in both modes, I found the steering weight and response completely well suited to the car, making it drive "smaller" than it is.

        it's a BMW 7L competitor, and the 7L with xdrive starts off at 10k more than this.. If it was an A6 pulling that price, then yeah I'd have to agree with you.
