Most of those get asked by "grown ups" on this forum all the time.

I'll tackle the first one, feel free to chip in, at least all the answers will be in one place in future.

In the last 20 years a lot of technical developments have come in. Fuel injection and computer control is the way to go. 20 Years ago most cars used a carb and points to alter the timing.

We also make use of turbochargers a lot more. The drive for efficiency and low fuel usage has also pushed the smelly old clunky diesel into a whole different league.

Processes such as Cryogenic treatments, and systems such as water injection and nitrous are also gaining popularity. Modern engines are also a lot more reliable than they used to be.
