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.
Yeah the EPA TDI bullshit is what I was talking about. It blows my mind to meet EPA "Standards" they had to make the engine perform worse and be less fuel efficient.
How does that blow your mind?
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.
Not the process, the standards. Burning more fuel to "reduce emissions". then I have to spend a bunch of money "fixing" a brand new vehicle to get the power and fuel efficiency the car was always capable of in the beginning.
Your Jetta can only hit those numbers rolling coal.
Awesome! I'll have a "peace love" and lgbtqaaip2s+ bumper stickers to really confuse everyone.
