Secret Out As Ferrari Boss Admits That Touchscreens Cost 50% Of Physical Buttons
Car manufacturers have spent the last decade convincing buyers that massive touchscreens and touch sensitive panels are premium, futuristic features. Now, the CEO of Ferrari, Benedetto Vigna, has confirmed to AutocarIndia the auto industry's open secret. Touch controls cost exactly half as much to manufacture and install as traditional physical buttons and rotary dials.
The ongoing shift towards entirely digital dashboards is primarily an aggressive cost cutting measure disguised as technological progress. This admission from a high-performance manufacturer highlights how mass-market brands are saving massive amounts of money on the assembly line.
By replacing tactile switches with a single glass panel, car makers are completely eliminating the complex manufacturing processes required for individual plastic, metal, and rubber components.
The primary cost advantage comes down to how modern vehicles are wired and engineered. In older vehicles, every single physical switch required its own dedicated copper wire running all the way to the specific component it controlled.
This traditional approach meant vehicles had to carry heavy, expensive, and incredibly complex wiring harnesses. Today, manufacturers use CAN bus and ethernet connections that allow a central touchscreen unit to send digital signals to various parts of the car simultaneously, drastically reducing the cost of materials and overall vehicle weight.
A physical switch is also highly limited in what it can do. It usually functions as a simple mechanism to turn a feature on or off. A touchscreen, however, relies on software customization to perform multiple complex tasks from a single piece of hardware.
Take cabin ambient lighting as a practical example. A physical knob could only control the brightness level. To change the colour of the lights, a manufacturer would have to design, source, and install an entirely separate switch.
With a touchscreen, programmers just add a virtual colour meter to the user interface. This allows the driver to change the lighting to a million different colours simply by dragging a cursor across the screen, a level of customization that is impossible to achieve with a physical switch.
While removing heavy wiring and expensive mechanical switches helps corporate profit margins, it creates a concentrated risk for the owner. By relying entirely on a touchscreen and ethernet connectivity to make different vehicle components talk to each other, manufacturers have built a dangerous single point of failure into the cabin.
If a physical air conditioning dial breaks, only the air conditioning is affected. But if the central touchscreen freezes, glitches, or suffers an ethernet connectivity issue, the entire control system goes down at once.
When essential driving controls and climate settings are buried inside a display menu, a software crash literally turns the car into a rolling brick. The driver loses access to basic vehicle functions until the digital system is fully rebooted.
The biggest problem with this touchscreen obsession is the total lack of physical feedback. Drivers cannot feel a digital button. Simple tasks that people routinely do using muscle memory, like turning the air conditioning on and off or adjusting the fan speed, now require looking away from the road and staring at a glowing glass panel to find the right digital icon.
Euro NCAP: No physical buttons, no 5 star rating
This distraction creates a severe safety hazard. The situation has become critical enough that automotive safety authorities are finally stepping in to mandate changes. Regulators in both European and Chinese markets are actively cracking down on the complete removal of physical controls.
Physical buttons for critical functions mandatory: China
They are drafting rules stating that essential vehicle functions must be operated by dedicated physical switches. As these new safety mandates take effect globally, car makers will be forced to bring back tactile buttons, proving that saving production money on a screen is simply not worth compromising driver safety.
