Beyond Hypercars: How Rimac’s Croatian Ingenuity Electrifies the BMW i7

In the rarefied air of the hypercar world, the name Rimac Automobili evokes images of the record-shattering Nevera, a battery-electric titan of performance and technology. Yet, the company’s most profound impact on the automotive industry is quietly unfolding far from the spotlight of drag strips. Nestled in Zagreb, Croatia, Rimac Technology has emerged as a pivotal force, supplying the beating heart for some of the world’s most prestigious vehicles. The latest and perhaps most telling testament to this shift? The flagship BMW i7 sedan. This partnership is not merely a supplier agreement; it’s a powerful narrative about how a nimble, visionary company from a non-traditional automotive hub is fundamentally shaping the future of luxury mobility.

The Silent Revolution: From Niche Innovator to Industry Keystone

To understand the significance of the BMW i7’s Rimac-derived technology, one must first appreciate Rimac’s unique trajectory. Founded by Mate Rimac in a garage, the company initially turned heads by creating electric conversions of classics like the BMW E30. However, Mate’s vision was never limited to bespoke projects. The core ambition was to develop proprietary electric vehicle (EV) technology so advanced that it would attract the attention of the industry’s giants. This two-pronged strategy—maintaining the halo effect of the Nevera hypercar while aggressively developing B2B technology solutions—has proven masterful. Today, Rimac Technology operates as an independent, industry-leading supplier of high-performance battery systems, electric drive units, and electronic components.

Why the BMW i7 is a Landmark Project

The BMW 7 Series has long been the embodiment of automotive luxury and technological leadership, a car that previews the future of the brand. The electric i7 variant carries the immense responsibility of proving that zero-emission driving can coexist with—and even enhance—ultimate comfort, refinement, and performance. BMW Group did not select its technology partners lightly. By choosing Rimac Technology to supply the battery system for the i7’s high-performance M70 variant, BMW signaled a profound vote of confidence. This move validates Rimac’s engineering philosophy and proves that its solutions meet the most stringent standards of quality, safety, and performance demanded by a German automotive titan.

Deconstructing the Power: What Rimac Brings to the i7 M70

The collaboration focuses on the very core of the electric vehicle: the battery system. For the BMW i7 M70 xDrive, Rimac Technology delivers a cutting-edge, high-voltage battery pack that is far more than just a container for cells.

1. The Architecture of Energy

Rimac’s battery pack is a masterpiece of integration. It utilizes the latest generation of nickel-manganese-cobalt (NMC) cells, arranged in a module and pack architecture designed entirely in-house. This bespoke design prioritizes energy density to maximize range, while also ensuring optimal thermal management and structural rigidity. The pack becomes a stressed member of the vehicle’s chassis, contributing to the i7’s renowned solidity and safety.

2. Unleashing (and Managing) Extreme Performance

The i7 M70 is no ordinary luxury sedan; it produces a staggering 660 horsepower. Delivering this power on demand, repeatedly, requires a battery system capable of immense discharge rates without degradation or overheating. Rimac’s expertise, forged in the crucible of hypercar development, is critical here. Their battery management system (BMS) is a software and hardware marvel, precisely monitoring and balancing each cell group to ensure peak performance, longevity, and safety, whether pulling away from a standstill or during sustained high-speed travel.

3. The Thermal Management Imperative

Performance is nothing without consistency. Rimac’s integrated thermal management system is a key differentiator. Using a complex network of cooling channels, it maintains the battery cells at their ideal temperature window regardless of external conditions or driving style. This not only protects the battery but also ensures that the i7 driver has full power available at all times and supports ultra-fast charging capabilities.

The E-E-A-T of Rimac Technology: Expertise, Experience, Authority, and Trust

This partnership is a case study in Google’s E-E-A-T principles (Experience, Expertise, Authoritativeness, and Trustworthiness), which are crucial for content and, by extension, for the companies it describes.

Expertise & Experience: Rimac’s expertise is not theoretical. It is hard-won through over a decade of focused R&D, extreme testing, and real-world validation in the most demanding electric vehicle application possible: the hypercar. The company employs hundreds of world-class engineers specializing in electrochemistry, software, power electronics, and advanced manufacturing.

Authoritativeness: Authority is conferred by peers. Being selected by BMW, a paragon of engineering rigor, as a Tier 1 supplier for its flagship model establishes Rimac’s authoritativeness in the field. This follows major partnerships and investments from giants like Porsche, Hyundai, and Kia, further solidifying its industry standing.

Trustworthiness: In the automotive sector, trust is built on safety, reliability, and delivering on promises. Rimac Technology builds trust through its meticulous engineering processes, compliance with global automotive standards (like ISO 26262 for functional safety), and its flawless execution for clients. The i7 M70’s performance and reliability are, in part, a testament to that trust.

The Bigger Picture: What This Means for the Automotive Industry

The Rimac-BMW story is a microcosm of a broader industry transformation.

• The Rise of the Technology Enabler: The old model of carmakers developing every major component in-house is fading. The EV era has given rise to specialized technology enablers like Rimac, who can innovate faster in specific high-tech domains.
• Geographic Diversification: Innovation is no longer the sole province of traditional automotive hubs like Stuttgart, Wolfsburg, or Tokyo. Rimac’s success puts Zagreb, Croatia, firmly on the global EV map, inspiring a new generation of engineers and entrepreneurs worldwide.
• Democratizing Hypercar Tech: The technology pioneered in the million-dollar Nevera is now being refined and scaled for a flagship luxury sedan. This trickle-down effect accelerates the advancement of all electric vehicles, bringing once-exotic levels of performance and efficiency to a broader audience.

Driving Into the Future

The BMW i7 gliding silently down the autobahn is a symbol of a new automotive paradigm. Its serene luxury is underpinned by a fierce, Croatian-engineered electric heart. This collaboration between an established German luxury marque and a disruptive Croatian innovator is more than a supply chain story. It is a powerful demonstration that the future of the automobile is being written by a diverse coalition of the willing—where agility, deep technical expertise, and a relentless focus on innovation can empower even the most revered brands to reach new heights. Rimac Technology, built in Zagreb and now driven worldwide in the BMW i7, is not just helping to power a car; it is helping to power an industry-wide transition.
