Automotive & motorsport T
he automotive industry is undergoing a radical shift that is fundamentally changing how we perceive and interact with vehicles. The once-dominant Internal Combustion Engine (ICE), which powered automobiles
for over a century, is gradually giving way to a new era of Electric Vehicles (EVs). This shift represents more than just a change in propulsion, but also a sustainability and environmental consciousness. Concerns about climate change and depleting fossil fuel reserves are driving the need for greener and more efficient modes of transportation. EVs have emerged as a promising solution, offering lower emissions, reduced reliance on non-renewable resources and improved energy efficiency.
One of the primary consequences of the shift to EVs is the integral role that software plays in the design, manufacture and operation of a vehicle. Unlike traditional vehicles with mechanical systems largely driven by engines and transmissions, EVs rely heavily on sophisticated software to manage intricate components, such as lithium-ion batteries, electric motors, regenerative braking systems and power distribution units.
THE PROBLEM According to Ford’s CEO, Jim Farley: “It’s so difficult for car companies to get software right. We have about 150 modules across the car, developed by 150 different companies, written in more than 100 different languages, that don’t talk to one another.” Historically, OEMs leaned on a familiar model, outsourcing their software needs to
tier one suppliers, aiming to secure competitive bids through market-driven competition. However, software-intensive EVs have altered the industry's landscape. Vehicles are no longer just mechanical entities, but complex software-driven platforms that require seamless integration of hardware and software.
As a result, the traditional outsourcing model has encountered limitations in terms of agility, responsiveness and control over the software development process. The ecosystem of modern vehicle manufacturing is incredibly intricate. Despite a vehicle carrying a singular manufacturer’s logo, its functionalities are carried out by a collection of modules from a diverse range of suppliers who provide their proprietary software and intellectual property, resulting in a decentralised framework. This approach, while fostering diversity, presents a considerable challenge due to the amalgamation of conflicting programming languages and disparate software structures. Consequently, the once straightforward tasks of software have transformed into a development, upkeep and improvement nightmare.
THE SOLUTION
Recognising the need for greater autonomy and flexibility, an increasing number of automakers are pivoting toward in-house software development. This strategic shift allows them to establish direct control over the design, development and implementation of critical software components. By developing their own software expertise, OEMs gain the capacity to tailor solutions to their unique needs, accelerate innovation cycles and swiftly adapt to rapidly changing technological trends.
Establishing dedicated teams of software engineers allows automakers to mirror the vertical integration model that has proven successful for players such as Tesla, ensuring greater cohesion between software and vehicle design and ultimately enhancing their competitiveness.
Embracing a model of vertical integration will be a pivotal strategy for legacy automakers aiming to thrive in the EV market. A similar strategy has been implemented by Chinese ICE automakers, who identified EVs as a distinct product category and consequently established separate entities for their EV operations, an approach which has led to remarkable success.
HURDLES
The transition from outsourced software to in- house development is not without its obstacles, as the industry must now navigate the uncharted waters of attracting and retaining software engineering talent. This transition reflects a seismic shift in the industry's employment landscape, where traditional mechanical engineering expertise must now harmonise with cutting-edge software prowess. The sector now finds itself in direct competition with the tech industry, renowned for its dynamic work environments and the promise of shaping the digital future. Central to this challenge is the stark contrast in compensation expectations between the two sectors. Software engineers are lured by the siren call of Silicon Valley's tech giants, where six-figure starting salaries, stock options and flexible work arrangements form a compelling package. These enticing offerings often dwarf the more conservative compensation structures historically prevalent within the automotive industry.
