Exhaust systems need replacing, usually far more frequently than most people do. If you've got a rusty mess of an exhaust system, you're just blowing unburned fuel through your engine.
I think 80 years of R&D is overly generous. There's been no fundamental change to the ICE since its invention apart from the addition of more and more compensatory systems being introduced to mitigate the shortcomings of the traditional four-stroke piston-driven engine. The Otto cycle sucks but we stuck with it because it was the best trade-off between implementation cost and mechanical performance. 120 years ago.
- smackfu 14y ago20k miles is like 1-2 years of ownership. Maybe a Porsche needs that kind of crazy maintenance?
- maxerickson 14y agoMy car spent 15 salty winters in Michigan. 1 exhaust component has rusted through so far (too bad for me, one of the convertors). Quality control and goes a long way. I don't even wash it as much as I should. Just an anecdote, but I bet the data on modern vehicles is pretty ok. Also fuel injection is a huge innovation. A thousand carburetors in a chip and all that.

That same type of advancement in the electric world should translate directly into longer range (perhaps faster charging and/or easy battery swaps). So in 80 years... do you think we'll still be worried about getting 200 miles out of an electric car? Doubtful.
