Engine noises as in internal-combustion-engine noises? Unlikely.
Even internal combustion engines are pretty silent these days, unless the maker deliberately wants that nice V8 gurgle so popular in the 1970s.
There's only one electric car that I know of that deliberately makes a noise (not plays a noise), the Zerocarbonista, which is a loud electric motor, not ICE sound. Plus I seriously doubt Apple would be following its design cues.
Would be cute if Apple made an hybrid, just so nobody could complain about range.
Tesla is essentially a battery company with expertise in battery management. They will keep coming up with products that are clever uses for their batteries.
Apple in iPhone particularly, have demonstrated their mastery of battery management. It wouldn't surprise me to think they would like to take on Tesla in the battery management stakes and produce an electric car. Just as Apple claims to be the #1 camera maker in the world, they would like to claim they are the #1 car maker as well. Have to sell a lot of cars, though.
Now how could Apple make a car as compelling and paradigm shifting experience as iPhone was…??
You have to admit, the field is wide open. Lazy ICE manufacturers have been creaming profits off $50 engines with incremental and cosmetic yearly updates for decades now.
Where is that watch 2?
