Oh wait, it's the laws of physics that have greatly diminished progress in this area...
- nickff 12y agoOne would think that true based on the thermodynamic first principles of the Otto and Diesel cycles, but you are actually incorrect due to a number of innovations such as fuel injection, EFI, direct injection, intake design, CFD analysis, materials advances which allow higher temperature and more efficient combustion, and turbocharging.[1] In addition, I happen to work on automotive and small engines, and can assure you that engine reliability has dramatically increased over the whole span of their existence, and every interval thereof.

- Florin_Andrei 12y agoPlease forward that link to my 2014 Honda Civic, which didn't get your memo and has the same fuel efficiency like my old 02 Civic.
- nickff 12y agoSo you bought a larger, heavier car, with a more powerful engine, and you think the problem is that engines are not getting more efficient?
