BMV vs. Audi: Who Really Started It All?

When you compare Audi and BMW to see which is the real pioneer, both have deep roots.

Audi inherits its legacy from August Horch, who started Horch & Cie. in 1899 and later founded Audi in 1909. Meanwhile, BMW began in 1916, but it wasn’t until 1928 that they built their first car.

Audi stands out with the 1932 Auto Union, which brought four car makers together; its logo with four rings is a nod to this.

BMW, however, made its mark with sporty engineering, especially after launching the iconic BMW 328 prior to WWII.

Both brands shaped the industry, but Audi’s older start and ground-breaking Auto Union make it a serious contender for the true “OG” of German automobiles.

Today, each brand has global reach and a dedicated following that keeps it at the forefront of innovation. Their rivalry continues to push the standard for German automotive excellence.
