When consumers step inside a new vehicle today, they expect connected, immersive in-cabin experiences that mirror the sophistication of their personal devices. Delivering on this expectation, HARMAN is bringing its extensive in-cabin technology expertise to the all-new Tata Sierra, ensuring the iconic SUV offers intuitive, seamless, and truly future-ready experiences for drivers and passengers alike.
The debut of the new Tata Sierra marks a significant expansion of HARMAN’s long-standing collaboration with Tata Motors Passenger Vehicles Ltd. (TMPVL), and ushers in the next era of connected mobility. At the heart of the Sierra’s in-cabin experience is HARMAN advanced infotainment and digital instrument cluster capabilities with an upgraded JBL audio system supported by HARMAN Ready Connect, all working together to deliver a driving experience that is more immersive, intelligent, and future-proof than ever before.
High-Bandwidth Connectivity Powered by HARMAN Ready Connect
The Tata Sierra features HARMAN Ready Connect, a locally manufactured next-generation suite of telematics control units (TCUs) designed to help drivers and passengers stay connected to what matters most, even in challenging environments.
Ready Connect enables:
5G-ready telematics, built on a 3GPP-standards based modular network access device (NAD) architecture designed for seamless migration from 4G to 5G technologies
Safety features, including emergency call, stolen-vehicle tracking, and roadside assistance
Infotainment and productivity, enabling HD streaming and video conferencing in the cabin
Connected services, such as over-the-air updates, cybersecurity, diagnostics, remote operations, and cloud integration
Smart conformal antenna, that maximizes radio frequency performance while reducing cable loss
These capabilities deliver faster, more secure, and more reliable connectivity while providing TMPVL with a scalable, future-proof platform to introduce new services quickly and efficiently.
“The Tata Sierra has always been iconic and the all new Sierra is reimagined and recrafted for a new era,” said Suman Sehra, VP, Portfolio Management, Connectivity at HARMAN International. “HARMAN Ready Connect represents the shift toward software-defined, experience-led mobility, and the new Tata Sierra is a perfect expression of that evolution. By collaborating closely with TMPV’s R&D team, we focused on value co-creation and delivered a platform that brings high-performance connectivity, scalable architecture, and future-ready digital services to support the connected digital life. This partnership demonstrates how a modern, product-driven approach and collaborative engineering can unlock transformational value for global automakers and consumers alike.”
An Immersive and Personalized Cabin Environment
The Tata Sierra introduces a cohesive digital experience designed to elevate daily driving as well as long journeys. Powered by HARMAN’s latest infotainment architecture, the vehicle includes:
A Horizon View Display, that offers individualized entertainment with speaker or headphone support with JBL Modes
Gaming support, including game controller (joystick) compatibility for passengers on the PID
Enhanced audio experience, with Dolby Atmos
Immersive cabin experiences, featuring Relax Mode for calming, sensory-rich visuals and audio, along with Silent Mode for selective muting of non-regulatory alerts
Advanced visibility systems, with Surround View System (SVS) and 4sight Blind-Spot view Monitoring for both infotainment and cluster displays
Integrated navigation, powered by MapmyIndia’s native in-vehicle mapping solution
These features work together to transform the vehicle into a connected, personalized space that adapts to passengers’ needs throughout each drive.
HARMAN Ready Link Marketplace, a unified digital commerce platform that allows drivers to access a rich ecosystem of in-vehicle Android apps and third-party content, is also available in the Tata Sierra. With Ready Link Marketplace, the Tata Sierra offers users a fully connected and personalized in-cabin experience, while staying in control over content, brand experience and the user relationship.
JBL Premium Audio with Industry-First Innovations
Audio in the Tata Sierra is powered by a premium JBL system that delivers a rich, multi-dimensional sound experience, refined for the cabin. The system introduces a 12-speaker system with enclosed subwoofer and soundbar, a first for an Indian automaker.
A Landmark Evolution in the Tata Motors Passenger Vehicles Ltd. + HARMAN Partnership
The Tata Sierra marks a meaningful expansion of the multi-year collaboration between TMPV and HARMAN. What began with branded audio systems has grown to include displays, high-performance connectivity, and infotainment, cementing HARMAN as a major partner in TMPV’s supplier ecosystem.
As part of this expanded collaboration, HARMAN has also initiated “Make-in-India” production of Ready Connect at its Pune facility. Manufacturing the telematics product in India enables TMPV to benefit from shorter development cycles, greater supply-chain agility, and technology tailored to the needs of Indian consumers and driving conditions.
“It’s an honor to help drive the Tata Sierra into its next era with breakthrough technologies that deliver truly intuitive and deeply connected experiences,” said Krishna Kumar, Managing Director & Automotive Head, HARMAN India. “The Tata Sierra holds a special legacy in India’s automotive story, and this launch is a significant moment—one that demands the very best in modern innovation. Our collaboration with TMPV, which started almost 12 years ago, is accelerating the convergence of consumer technology and automotive excellence, resulting in an ecosystem that’s personal, premium, and unmistakably future-ready.”
According to Mr. Mohan Savarkar, Chief Product Officer and Chief Corporate Quality Officer, Tata Motors Passenger Vehicles Ltd., “With the Sierra, our focus was to create a cabin experience that feels as advanced and intuitive as the world our customers live in. Connectivity, digital interfaces and audio are no longer add-ons—they define how people engage with their vehicle every day. Our collaboration with HARMAN enables us to deliver a future-ready architecture, immersive in-cabin experiences and premium audio that together elevate the sense of technology, comfort and personalization inside the Sierra.”
