The rivalry between Mercedes-Benz and BMW is the stuff of legends and continues to this day, but sometimes, even if very seldomly, the two brands give each other a nod of approval. In an Instagram video posted by BMW, the brand gives praise to the all-new Mercedes-Benz S-Class. The car which made its debut last week has been setting new standards for luxury cars, with crazy tech and a new hybrid model that has also been revealed, placing it close to the top of its class, but BMW has been clever in its messaging, which gives a nod to both the new S-Class, as well as the BMW 7 Series - the German automaker's own rival to the S.

In the video, we can see an aerial shot of an S-bend poetically stringing through an open field bordered by some trees. The words "Nice S" appear as the camera hovers over said S-bend. Eventually, a car can be seen driving the same road, which turns out to be a 7 Series. Multiple closeups are then shown of the BMW, taking away the spotlight from the S-Class. The Instagram caption reads, "Hey, nice job @MercedesBenz. We are big fans of the S too..." Clever wording for a clever little ad.

The all-new Mercedes-Benz S-Class is merely the start of a broader trim range, but for now your options are slightly more limited. The S500 gets powered by a 3.0-liter turbocharged inline-six producing 429 horsepower and 384 lb-ft of torque, while the S580 gets a 3.0-liter turbocharged inline-six offering 429 horsepower and 384 lb-ft of torque. Both cars feature a nine-speed automatic transmission and 48-volt mild-hybrid system. A new hybrid car has also been revealed: the S580e plug-in hybrid S-Class features a turbocharged 3.0-liter inline six-cylinder engine and a 28kWh battery pack with a gearbox-mounted electric motor for a total power output of 510 horsepower.
