Also remember that those trucks are both heavier and less aerodynamic than your Bel-Air. A well-equipped Tundra or Silverado is pretty close to the weight of your Bel-Air and Z3, combined.
I guarantee that your 70s motor isn’t really all that eco-friendly. Once all the emissions stuff is warmed up, those trucks are honestly pretty “clean” in regards to tail pipe emissions compared to even a car 20 years ago. Remember that CO2 and water aren’t the only things emitted, and while they’re worse on the CO2 front, anything without a catalytic converter is going to emit some pretty nasty stuff in addition to all all the CO2.
