I think I'm going to have an aneurism on trying to figure out why someone from MIT wasted their time with this. I thought it was a pretty well known fact

you cant have stricter emissions and more mpg, it will never work. Top gear drove a VW polo with a diesel engine from 1990 and it got 75mpg! The motor is not made anymore due to emissions.

Cant have the best of both worlds.

You can but you sacrifice drivability and performance. Tuning triangle; emissions, drivability, and economy.
