According to tests conducted by the California Air Resources Board, they also produce hydrocarbon emissions of 0.024 grams per mile, nitrogen oxides of 0.16 grams per mile, and carbon monoxide of 0.17 grams per mile.
Existing regulations set the limit at 4.1 grams per mile; EPA administrator William Reilly proposed to lower the standards to 2.5 grams per mile.
The 1965, 1970, and 1977 Amendments to the Clean Air Act led to the selection and implementation of specific Federal exhaust emission standards (in grams per mile) and resulted in the spending reported in this article.
For instance, in 2014, the US environmental protection agency (EPA) adjusted CO2 emission standards to 367 grams per mile. Similarly other governments across the globe are expected to follow this trend and act accordingly.
Test results replicating the road and aerodynamic load of a Hyperdrive-equipped large luxury car produced hydrocarbon levels of 0.002 grams/mile, carbon monoxide levels of 0.06 grams/mile, and oxides of nitrogen levels of 0.02 grams per mile. This compares favorably with current SULEV (super-ultra-low emission vehicle) standards of 0.01, 1.0, and 0.02 grams/mile, respectively.
