THE PROS AND CONS OF SOFTWARE RUNNING YOUR CAR

Software was a big theme for automakers attending CES 2023 in January. BMW, Stellantis, Volkswagen and a joint venture between Honda and Sony showed off upcoming or concept vehicles that are significantly reliant on computers and code.

The takeaway was clear: More and more vehicles will be run top to bottom by software, not hardware. In some cases, the future is already here.

What will it be like for shoppers when vehicles are dominated by bits and bytes instead of gears and gaskets? Experts break down what's in store.

SOFTWARE-DEFINED VEHICLES

The phrase “software-defined vehicle” is an industry term used to clarify the difference between a traditional car that is enhanced by technology and one that is run by technology.

While cars of the past 20 years have gained touchscreens and have plenty of engine- and safety-related computing power, those software features are largely stuck in time once the car rolls off the assembly line. The future holds that nearly every vehicle feature will be controlled by software, which offer the potential to improve features over time.

Another key difference is updatability. Consider the smartphone. Their manufacturers seamlessly update their software on a regular basis to fix bugs and breaches and add functionality. Software-defined vehicles work similarly. They have high-speed Wi-Fi and cellular connections that automakers use to send out software updates via the cloud to its vehicles. There’s no need for owners to bring their vehicles to a dealership or service center.
