The software issues that have hampered the build-up to the launches of Volkswagen’s new ID 3 EV and eighth-generation Golf demonstrate how important such systems are to modern cars – and how complicated they have become.
The software required for the previous Golf contained around one million lines of code – compared with 10 million for the ID 3. For companies traditionally focused purely on building the mechanical elements of cars, that increasing need for software presents a dilemma: do they buy in the new software that’s needed or make it themselves?
The Volkswagen Group has bet heavily on the latter, creating the new Car.Software unit, which officially becomes fully operational today. Headed by Christian Senger, who was previously in charge of the firm’s ID models, by the end of this year it will encompass 5000 staff gathered from various Volkswagen Group brands. By 2025, it plans to employ more than 10,000 staff worldwide – half of them in Europe, around a third in China and the rest in the US, Israel and India.
The Volkswagen Group’s goal is to raise the proportion of its cars’ software produced in-house from less than 10% currently to 60% by 2025. Senger said the easy path would be to focus on vehicle production and use the group’s scale to negotiate competitive supply deals with software providers, especially tech firms that are working on their own automotive operating systems, such as Apple and Google. But that was “out of the question” for three key reasons.
The first is manufacturing experience, which Senger said differentiates the group from “competitors outside the industry”. The second is the firm’s desire to “retain control of the entire vehicle architecture”. Senger said this is “the only way to ensure longterm competitiveness”.
The Volkswagen Group also believes that the huge number of vehicles it produces will give it a major edge. Senger said: “Scale is everything in software, in both cost and learnings from data. Software needs significant numbers of users to become powerful and efficient, and the number of cars we produce offers that.”
