English term
with hotter engines
How do you understand the final part? Does it mean the requirements are for hotter engines? Or is it another one of the things meant by the move to aerodynamic?

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

: Yes, i'd say it means modern engines designed to run hotter (as Terry R points out in his discussion post)

yes, I think that's more likely as well. Thank you.

Hotter engines as we move to aerodynamic engines.

As the vehicle design moves from classic to aerodynamic, we have more hotter engines.

[I meant aerodynamic design in the answer, not engine]
Discussion
The first one is that modern engines literally run physically hotter. Engines are more efficient when they are running hot and leaner (less fuel) mixtures burn hotter. Aerodynamic styling also reduces air flow under the hood and therefore cooling of the engine.
However, there is a second, more slang, meaning that a hot engine is a tuned engine that produces a lot of power relative to it's size. Unfortunately, this is also true of modern engines.
I suspect that the first meaning is the one intended here but I'm not sure enough to give an answer.
