More than I Expected...

I have driven a Lexus for the past 16 years. I have never has a bad experience, but wanted a change. It has been two months and 4,000 miles. The Audi has delivered in every way. I loved the test drive, but find myself learning more about the car and feeling more at at home in the Audi every time I hit start... I got a lot more than I expected. There is a huge difference in Japanese vs German engineering. Design, acceleration, handling, features, air ride suspension (wow!), and the way I fit in the adjustable seat. The A8 offers subtle and spectacular at the same time. Don't buy a MB, BMW, or a Lexus without driving the Audi. Definitely worth your consideration....

** May 2020 Update** Added Michelin Pilot Sport 4s summer tires. Car has 51k on it, no problems. Added Apple Car Play. Tweaks: needle sweep @ start & close windows/roof via remote. Still in motoring Nirvana ** Nov 2019 Update ** Turned 45k today. The car continues to amaze. Regularly scheduled maintenance is all it's needed. On the highway, the car is an absolute beast...... It is so hard to keep within 10mph of the limit... other cars line up behind me and we convoy. Just completed a paint refresh with total detail, and the car looks showroom new inside and out. This is not a head-turning exterior design like Jaguar, so don't expect folks to be staring at you. Interior looks like it came over on the boat from Germany... no creases in the leather or creaks in the cabin. The 22-way seats with massage really dial you in to your preferred seating position. 2015 did not offer Apple Car Play, I've ordered an aftermarket unit. The new A8's are almost all touch-screen controlled, a step back if you ask me. All systems work as they are supposed to. The 4.0 twin turbo-charged V8 sings so sweetly... was cruising along at 85 when circumstances dictated I maximize output by completely opening the throttle, and looked down to see 120 in a flash. I hope this car is as reliable as it is fun to drive.... it certainly qualifies as a 10-year or more keeper. Did find a new dealer who is responsive, communicative, intelligent. They are a 40 minute drive in to downtown Pittsburgh. In addition to having a nice meal downtown while my car is service, I drive right by the crappy dealer and flip them off! ** Nov 2018 Update ** When you play in this league, you expect to be satisfied and the A8 delivers in every arena. The lone blight is the dealer experience. I cannot overstate the supreme confidence this engine inspires. It forces you to re-calibrate your senses because you CAN make that pass and you CAN make it into that spot as the acceleration is, as Edmunds has describes, a flood of power. Kudos to those of you with an S8, how do you not get tickets weekly? Had the "pleasure" of the accident mitigation system stop the car from 55mph as we rounded a sharp curve to find a Navigator planted in our lane. The Audi slammed on the brakes and we stopped about three feet short of the Dead Lincoln. Wow what an engineering feat. This is truly a Jekyll and Hyde experience...put it in Comfort mode and effortlessly coddle your passengers for hundreds of miles at a time....dump those passengers at the bus station and dial up Dynamic mode and avoid the interstate all together as you attack the twisties on your way home! If you want me to pick nits, it's dealer-related. There is a known vibration remedied by replacing the downpipes (which were redesigned to accommodate the fix), and on my first visit to the dealer they said is was the torque converter operating correctly...WRONG. Subsequent visit with TSB info in hand and they changed their tune. I shouldn't be the one who has to diagnose issues, especially known ones. Looking to switch dealerships for future service. Only other nit is highway mpg is not as advertised.. I cannot get 30mpg on the highway no matter how I coddle it, so I'll settle for 27-28. Around town mpg's are spot on at 20, so my combined of 22.4 over 9000 miles is as-published. I did buy a set of dedicated winter wheels/tires and couldn't be happier. The cold-weather compound on the Conti T810S is a real confidence boost while highway driving through slush and puddles. I know because it literally snowed the day after I had them put on! Everything inside the car works beautifully. Once you become familiar with the dash layout you don't have to look away from the road to get things done, and that is the bane of the touchscreen: You must look to find the intended information target, where I can run my finger and use tactile sensation to find the correct command. But nearly every manufacturer is heading down TouchScreen Avenue... Since I bought CPO and couldn't pick the options I wanted, the only one I long for now that winter has arrived is the heated steering wheel, a minor inconvenience I have remedied with a very nice pair of driving gloves from Orvis. Original Review May 2018 Moving from a CTS6 Performance with it's awesome chassis, the A8 outshines GM's iron in virtually every category. But, to be fair, the A8 is $30k MORE so it should be better. This engine is magnificent, rocketing to 60 in 4.3 seconds. No matter where you are in the rev range, stomping on the gas just plants you back in the seat. 0-60; 40-80; 80-?? it does not matter this car is just Point and Shoot. The Dynamic Steering and Sports Differential give you a degree of confidence and road feedback unparalleled in cars this size. The interior is better than MB or BMW.... coddling, expansive, top quality materials deftly blended to accent and compliment each other.

A Truly Fine Automobile

2015 Audi A8 3.0T quattro 4dr Sedan AWD (3.0L 6cyl S/C 8A)

We've owned luxury cars by Lexus, BMW, and Mercedes. After buying my first Audi, a 2016 A6 3.0 earlier in 2015, my wife was so impressed driving my car that she traded her Lexus RX350 in for a A8 L with the same spunky V6. I can't help but to compare the drive, handling and ride quality of the A8L to a Lexus LS460L I traded for my A6 earlier this year. The Audi beats the Lexus hands down. This A8 L handles so securely for such a large car. The V6 is strong, and provides plenty of power. The car is hushed, substantial, has a huge back seat, yet handles like a smaller sedan. Technology is top notch, with the exception of no USB ports? What was Audi thinking? Otherwise, the navigation is quite good. Interior fit and finish is superb, with great feel at every touch. The massaging and ventilated seats are a nice touch as well. Fuel economy with the V6 is excellent, at 34 mpg in a 1000 mile trip at highway speeds in excess of 75 mph. A very comfortable long haul road car. Combined mpg has been a respectable 25 mpg. The LED interior lighting is subdued and well executed. The LED headlights are piercing the night driving. If these Audis hold up well, we are certainly going to continue to be Audi repeat buyers.

Dieselgate Audi

2015 Audi A8 L TDI quattro 4dr Sedan AWD (3.0L 6cyl Turbodiesel 8A)

The second generation V-6 TDI is a fabulous car. Such a shame that VW/Audi felt they had to cheat on the emissions tests, because the repairs done to meet spec had virtually no impact on the car's operation. About all they did was set the shift points at a higher RPM. But because of the cheating, diesel cars are probably dead in the US market. One can make a good case that the emission standards are ridiculously high, but that's not the point. The problem is that VW/Audi cheated to get around them...and they wouldn't have had to. Because of all this, the value of these cars has fallen through the floor. But if you can get one for a song, you won't be disappointed. The car has plenty of power, handles beautifully, rides very comfortably, and gets amazing fuel economy for its size. I have easily hit mid-40 mpg on freeway trips (at least according to the computer). The only thing that falls down is the navigation system. The voice activation is poor. It often can't find a specific address. It is slow. Audi connect, which overlays Google Earth on the map, is a neat toy, but it is too expensive for what it is. My other gripe is repair costs. Once the warranty expires, this baby is going to be expensive. It uses odd size tires...and goes through them quickly. I think I paid about $1600 for a set of four new Michelins. At least they are good tires. The Pirellis that were original were horrible. Very noisy. And the brakes don't last very long either. New front pads and rotors at around 30K...one independent shop quoted $1200...got them done at another for around $800. Can't imagine what the dealer would get. Dealer gets $100 for a set of wiper blades, for Pete's sake. Once the Audi Care expires, routine maintenance goes to an independent. Dealer prices are beyond belief. But the Audi A8 diesel is truly a great car, better than the several BMW and Mercedes I've had in the past. No regrets whatever about buying this car!

One smooth car from look, to ride, and handling

My A8 L is a 2017 3.0T Quattro Tiptronic with everything including the adaptive chassis and front power seats with massage. In other words, you really can't beat this car for comfort. Even the controls are laid out in a configuration that makes sense, and with easy access, so your fingers don't fumble around when you want to reach out for something. The highest compliment I can give this car is that I actually enjoy being a passenger when my wife is driving. Not that my wife is a bad driver, but usually I am a horrible passenger. The ride is amazingly smooth and acceleration is close to driving a sports car. The safety features are amazing and should you be using lane assist, you will get an audible warning to tell you to put your hands back on the wheel. Some people aren't fans of all the safety features but I am. Given the condition of roads and the number of distracted drivers out there, I like feeling I might have an edge. The navigation system is excellent and it also provides you with traffic conditions and problems ahead. I did purchase extended warranties guaranteeing me bumper to bumper protection through 2023, including scratch protection. These automobiles are really comfortable computers on wheels and only a fool would fail to protect themselves in case a computer board or chip gets fried. My collision insurance took a slight jump as these wouldn't be inexpensive cars to repair, but it wasn't a bump such that it is highly noticeable; more like a hundred dollar jump. My wife has pretty much appropriated this car. She prefers the shift over the newer electronic shifter where you press "P" for park rather than actually move the shift into park. No doubt the 2018 model has upgraded but my wife is putting off the inevitable as long as she can. Now, my wife isn't a lead foot by any means, but she likes a car to jump when she hits the accelerator. She also appreciates the ease by which she can maneuver. Friends appreciate the comfortable back seat and love being passengers. The trunk has been criticized for being small but we have had no trouble and have easily put four suitcases inside of it. If you like comfort and ease of handling then you might want to find one of these in the used car lot of a dealer as unfortunately, the car depreciates rather quickly. I can't understand why as it is a nice car and you will get compliments if you enjoy that sort of attention. And now after driving the car for two years, my enthusiasm hasn't diminished. This car is like driving a cloud. Our son is a big fan of e-cars, so maybe in five or so years we might consider an electric Audi but for now, we are keeping the car. It's been three years with this A8 and my wife will not give up this car. Upgrades to newer models aren't that significant, and my wife is just completely happy driving her car.
