Matt Haughey: ‘The Car Industry A/B Tested Selling a Car With and Without CarPlay and the Results Are Not Shocking’

[John Gruber]

Matt Haughey:

One case in point is the Honda Prologue EV. It’s a partnership between Honda and Chevrolet, where the Prologue is basically a Chevy Blazer EV with Honda badges, slight visual differences in the sheetmetal and interior, but all the underpinnings are straight up Chevy. Even though the keys say Honda on a Prologue, it’s a General Motors key design with a Honda logo over it.

But one big difference the Prologue has from the Blazer it is based on is this: it includes Apple CarPlay and Android Auto integration. [...]

For the years these cars were sold together, the Honda outsold the Blazer by 43%, 73%, and 166% in each time period. Today in 2026, people are buying a Honda Prologue over one and a half times more often than the Chevy Blazer EV the Prologue is based on.

It’s not a perfect test. It’s reasonable to argue that Honda has a better brand and reputation than Chevrolet, and is just plain better at selling cars. But the trendline over the last three years is pretty stark.
