Comparing 2018 BMW 4 Series to 2018 Audi A5

Deciding between a BMW 4 Series or an Audi A5 is not easy. Both coupes fall into the luxury segment, flaunt outstanding horsepower, opulent cabins, thrilling features, and intelligent driving technology. BMW 4 Series is small but mighty and similarly, the Audi A5 offers equally exhilarating features. Whether a crossover or in a convertible form, both models give each other a tough competition. And to satisfy this technology-frenzy world, these high-tech cars have everything in order for 2019 and ready to impress.

While the 2019 BMW 4 Series ups the level with its top-notch technology and smart-app integration ultimately setting a higher benchmark, the Audi 5 continues its conservative styling and a non-updated chassis for this year too. But that’s not just enough to declare BMW as the winner. As we get into each small detail through this side-by-side comparison, we will find out how BMW stacks up to this fierce competition.

How Does The BMW 4 Series Win the Clash?

Because both of these Germanic automobiles run literally neck-and-neck in this comparison, it’s difficult to pick a winner. But, we have a few reasons favoring the winner BMW.

  • 4 Series’ 8-speed automatic surely outsmarts the speed-shifting seven-speed automatic of Audi.
  • BMW’s upgraded infotainment system offers better features.
  • J.D Power ranked BMW at the 8th for reliability whereas Audi gets the 14th spot.
  • EPA-certification wise BMW 4 series is a Super Ultra Low Emissions Vehicle.
  • BMW promised better handling and stability with a wider rear 1.1 inches bigger than A5 and has an even weight distribution.
  • 4 Series also offers better maneuverability and handling with a shorter chassis, which is 3.6 inches shorter than the A5.
  • Space-wise, BMW 4 Series is little roomier than A5 with better front legroom, a little extra headroom, and a larger cargo space.
  • And, lastly BMW 4 outsold the Audi 5 by 86% in 2017.

The 2019 Audi 5 is certainly a strong competitor and practically, a rip-snorting coupe with many outstanding features. But it fails to impress while competing against the 4 Series titan of BMW. Even though Audi swooped in to add more depth in styling, reworked on car handling and performance with the 2018-redesign, the small design tweaks, and smart technology improvements certainly make BMW a better choice.

Sales team was excellent but finance and delivery were not good. Worst buying experience I have ever had with a car. I liked the sales person and the car so I endured it but could not recommend for others. The car seems awesome so far.

Awesome service today.. I had Brent as my service advisor for my Beamer today. Battery went back and check engine light came on. Took care of the diagnostic and battery replacement. Was able to get a shuttle home and back to the dealer once the job was done. Super awesome and happy with my car serviced by Brent and his team
