HARMAN and the BMW Group have expanded their longstanding partnership to include four new, recently launched car models. The BMW X3, BMW 6 Series Gran Turismo and BMW i3s deliver the state-of-the-art driving experience for which the BMW Group is known, while offering drivers and passengers a choice of immersive audio experiences, powered by Harman Kardon and Bowers & Wilkins.

The BMW X3, BMW 6 Series GT and BMW i3s all come equipped with a customized Harman Kardon premium sound system whose every detail is precisely tuned to the interior of each model for a unique, captivating sound experience. In the X3 and 6 Series GT, the sound system features 16 high-performance loudspeakers, including two subwoofers under the front seats, as well a 600-watt Class-D DSP amplifier with Logic7®-Surround that provides an exhilarating 360° music experience for all passengers.

For the all-electric, sporty BMW i3s, the Harman Kardon premium sound system with its 12 high-performance loudspeakers is designed to be energy efficient while still delivering powerful sound. The energy savings are achieved by combining a 360-watt Class-D DSP amplifier and high-efficient subwoofers.

Bowers & Wilkins Diamon Surround Sound


Available as a High end option in the BMW 6 Series GT, the Bowers & Wilkins Diamond Surround Sound System was designed by HARMAN`s acoustic engineers in cooperation with Bowers & Wilkins exclusively for the BMW Group. It features studio-grade acoustic technologies never before seen in a commercial car and exclusive materials like diamond, Kevlar® or Rohacell®. While diamond is the perfect tweeter material due to its unique stiffness-to-lightness ratio, Kevlar helps prevent distortion in the midrange and improves the off-axis performance, which is especially important in cars as it means all the listeners get the same great experience.

The Diamond Surround Sound System is seamlessly integrated into the interior of the BMW 6 Series GT, and combines 16 speakers with a 10-channel, 1,400-watt Class-D amplifier with QuantumLogic® surround sound processing for sound so flawless, natural and richly detailed that listeners feel as though they have been transported into the recording studio.


Delivering genuine driving pleasure and truly phenomenal sound, the wide range of BMW’s latest models are a perfect demonstration of how HARMAN’s and BMW’s dedication to detail and excellence guarantees a truly extraordinary driving and listening experience.

“We at HARMAN are proud to provide several tailor-made HARMAN car audio sound systems to BMW’s wide range of car models” says Mathias Brand, Senior Director, Car Audio Marketing Europe at HARMAN. “With our outstanding Harman Kardon and Bowers & Wilkins systems we are able to set exceptional standards in mobile sound experience and design.”
