Respectfully disagree. Lower emissions goes hand in hand with better efficiency. Think about it. The laws of physics apply here. More fuel = more emissions. Contrary to popular belief, today's engines are NOT "choked down" in any form. Look at today's engine specifications. Look at their performance. Back in the '60s and '70s, a 6 cylinder engine even in a mid-sized car was a DOG!! Yes, it would get the job done, but don't be in a big hurry about it. Today, a similar size engine is almost considered a muscle car! Engines in the 2-liter class are making 200 horsepower. 3-liter class is up around 300. They are powering that huge Chrysler 300 with a base engine of 2.7 liters. And it drives like a small V-8 did in the '70s. How can that be considered "choked down???"
As it was explained to me at manufacturer emission schools years ago, it is a 3-way split to make an engine and car combination to please every agency that controls it.
The customer wants performance.
The EPA wants low emissions.
CARB wants good fuel mileage.
To balance these items requires a lot of engineering skill to end up with a marketable product.
