The GMC HUMMER EV Pickup launches with Bose EV Sound Enhancement (EVSE) technology

22 March 2022, 11:18:27

With the launch of the GMC HUMMER EV Pickup, Bose is introducing its first-ever application of Electric Vehicle Sound Enhancement (EVSE) technology, bringing unprecedented sonic experiences to consumers of the world's first all-electric supertruck. Bose EVSE technology, along with a 14-speaker Bose surround sound system, is standard on the all-new GMC HUMMER EV.

EVSE technology helps GMC deliver a dynamic audio response for HUMMER EV's driver and passengers. Engineered to replace the mostly silent interior that comes with operating an electric vehicle, EVSE technology sends custom-designed propulsion sounds into the cabin through Bose speakers to refine and enhance the acoustic environment. Combined with immersive music provided by the Bose sound system, the inside of the GMC HUMMER EV is like nothing else on the road today.

During the vehicle development process, Bose engineers worked closely with GMC to integrate Electric Vehicle Sound Enhancement technology. Using a proprietary Bose algorithm and data gathered from the vehicle, EVSE helps mask undesirable noise produced by the electric propulsion system, while at the same generating distinct sounds for different drive modes.

The impact of EVSE technology is most pronounced in the GMC HUMMER EV Pickup's driver-selectable launch-control mode, called "Watts to Freedom," which enables the driver and passengers to feel the full power of the supertruck's acceleration from 0-60 MPH in a GM-estimated 3 seconds.

As the vehicle gears up for launch from a dead stop, EVSE technology is engaged to help prepare the occupants with audio cues. A purposefully crafted mix of electric guitar riffs and feedback gradually builds anticipation as the Bose subwoofer creates vibrations and the vehicle uses its adaptive air suspension to lower its height and center of gravity. The sound then shifts, signaling when the vehicle is ready for takeoff before the driver can finally unleash the HUMMER EV's 1,000 horsepower and 11,500 lb.-ft. of torque down the road.

For music and audio entertainment inside the GMC HUMMER EV Pickup, Bose applies its 40 years of experience in the automotive industry to engineer a 14-speaker sound system that delivers deeply impactful listening.

The Bose surround sound system features intense low-frequency performance, powered by 6x9-inch wide-range woofers — one in each front door — and an all-new bass box design, positioned under the rear seat and visible to passengers with a Bose logo for an experience that can been seen, heard, and felt like never before.

The system also includes proprietary Bose Centerpoint digital signal processing for enveloping surround sound in every seat and Bose AudioPilot signal processing to preserve the listening experience in all driving conditions — even when the HUMMER EV's removable roof panels are off.
