General Motors investing $854 million to build V8 engines amid EV shift

Tuning and accessories bolted on for sure. The Camaro owner is fine with a louder exhaust and premium being required while the SUV buyer wants a quiet exhaust and is probably too cheap to pay for premium fuel so they have to tune it for regular.

I'm thinking of a dealer installed GM cat-back exhaust, cold air intake and Camaro tune on my 22 3.6L Acadia that runs on 94 because the improved fuel economy saves money. Sorry to disappoint.
