A4 — Safety, Technology, Power, Good Looks!

‘21 A4 45 Premium + S-Line offers top safety ratings, amazing tech, a responsive and efficient power plant as well as good looks. What’s not to love! This is my third consecutive Audi; its bespoke cabin is a refuge at days end. 3D Bang/Olufsen sound is transformative. Team Ingolstadt hit a home run with this conveyance, most assuredly!

Great handling and very good acceleration and braking. The driving is secure around corners and on wet roads. The dynamic cruise control is a nice feature as well in highway driving. I've had cruise control on other vehicles, but for the most part never use it. With the 2021 A4, the dynamic cruise control feature does a very good job of adjusting speeds to the flow of the traffic -- also it seems to be a great way to optimize fuel economy in highway driving. In terms of interior comfort and features, the car is outstanding for the driver and front passenger. In addition to getting a new car, I also made a point of upgrading my cellphone. I thought about getting the technology package and navigation, but have been very satisfied with Android Auto on a new Samsung phone. The new phone adds value to the car, and the car's ability to make use of the new phone's features, adds value to the phone. I've found every excuse in recent weeks to take the car out on the road. There was a bit of a learning curve in the first few days as a first-time Audi owner, but the car really grows on you, things become much more intuitive after using the car for a few days. Even after reading the owner's manual front and back and nearly a month of ownership, I'm still discovering cool new features related to the way the car operates and integration with the phone and Audi app. Even with the more powerful engine, I have been getting good mileage too driving in Dynamic mode. e.g. up to 40 on the highway, 26 in town, about 28 overall. The only real downside is the relatively small backseat. The rear seat is made of fine materials, but there's not a lot of head and leg room for people 6 foot or taller. Also, in warmer regions of the country, it is worth considering ventilated seats and a lighter colored vehicle. Overall though, it's a great car. A superb daily commuter and ideal for trips. ADDITIONAL NOTE TO ORIGINAL REVIEW: Have had car for nearly 7,000 miles, still working great. Winter handling has been superb on secondary roads that aren't regularly plowed. Car heating system generally works great -- seat heaters are excellent. Steering wheel heater isn't really noticeable, but the car warms up quickly so this isn't really a feature that I miss or use. In terms of general maintenance, I try to make sure to keep the various car sensors clean. It's worthwhile investing in a microfiber cloth for the task. Audi also has a window cleaning solution that you can buy through dealerships. As far as minor gripes go, some of the add-on technology features still seem to be in a beta test mode. e.g. the MyAudi app worked great initially, but after a software update this past Fall there were issues for a few weeks trying to communicate with the car. The MyAudi app isn't a really essential function to vehicle operation, but it's a secondary feature that is nice to have when it works. Also, Audi has some subscription services that you can purchase through the MyAudi App including a short-term licenses for Audi's built-in in-car navigation software. My experiences with it were a bit mixed. The add-on feature allows you to view navigation data on the driver display along with the other gauge clusters. Without the built-in navigation feature (or short-term license), the navigation data, via Android Auto or Apple Car Play, only displays on the touchscreen on the center console. Additionally, the short-term license includes things like weather radar, which are nice to have, but not essential for daily use. I tried the short-term licenses out for a couple months. The first month the functions worked great. The second month that I tried, they didn't. e.g. navigation in particular did not active properly in the second month. I have stuck to using Android Auto instead for daily use, which works great.

Still the Best car ever

I found the car my dreams at a dealer who is a trick playing organization. I found another dealer, in the Denver area in Broomfield and they got the exact car that I have been dreaming about for many years. They did a dealer trade for me. They gave me a great price. They had no tricks. The car drives magnificently and has every feature I could imagine. It is nimble, not flashy and has a great driver seat which I care about very much. Car and driver magazine said that the driver seat was hard for tall people to get in and out of. But I do not find that to be true and I am a tall woman. Perfect car!

Best car in its class

45 TSFI Premium Plus S line quatrro Before buying this car, I tried the BMW 3, Benz class C, Lexus SI and more. The A4 is the most luxurious of all, especially the interior. Sitting in the car puts a smile on my face every time. Impeccable attention to details, superb quality material and everything works intuitively and put in the right place. The Bang & Olufsen sound system with 19 speakers is just something else and the best period. The seats are the most comfortable for its class and are very supportive. Driving it is an absolute pleasure. Really easy and pleasant daily driver, but you punch it and off it goes. The driving dynamics get more aggressive when you put the car in dynamic mode, suspension lowers and engine gets more exciting. Handling is excellent on twisty road. Overall, luxurious, confident , powerful and great pleasure to drive. Not to mention that Audi is ranked top in reliability in par with Lexus:

I purchased 2021 Audi A4 Quattro S Line for daily commutes. It’s quite luxurious, ride is smooth, it’s sporty, and every drive in this car feels special. It’s a great value and offers the full Audi experience in an efficiently sized sports sedan. For all the speed limits, this is enough power and performance for daily driving. Love the car!
