Vwagy group cars are still being made this way. Audi engine, Lamborghini transmission, etc. The internal components are just shared between productions to cut costs, while they tweak the timings in the computer to match the customer expectations.
They got their hand slapped by the EPA for the TDI emissions line, but the cars are basically performance vehicles detuned. You can supe a modern jetta or golf up for under 3k, 90% of it is just changing the intake and exhaust manifolds while changing shift timings. The Jetta models actually improve fuel economy with an APR tune.
Capturing emissions and recirculating them back through the engine to reburn them is inherently less efficient for power. It reduces the amount of emissions at the tailpipe at the expense of power and longevity. The EPA doesn’t give a shit about how much power your car makes, they care about the sulphur and NOx emissions from diesel engines making it into the air.
You can make a more fuel efficient and powerful diesel that will go for a couple million miles by straight piping it, but the emissions are god awful.

How does that blow your mind?

Your Jetta can only hit those numbers rolling coal.
