A List Some Carmakers Don't Covet

Carmakers' most profitable vehicles score at the bottom of EPA pollution scale.

DETROIT, Feb. 14 — Automakers are obsessed with ratings, from customer satisfaction to how many hours it takes workers to assemble a car. But there is at least one list many do not like to talk about.

The Environmental Protection Agency rates every vehicle according to the amount of pollutants coming out of the tailpipe that contribute to smog, which can worsen asthma and lead to cancer and lung damage. Many popular sport utility vehicles and pickup trucks rank at the bottom on the 0-to-10 scale. Among them are a number of recently introduced — and highly profitable — models.

Vehicles with ratings from 0 to 4 include four pickup trucks — the Ford F-150, Chevrolet Silverado, Dodge Ram and GMC Sierra — as well as sport utilities, including the Mercedes M class, Chevrolet Tahoe and Suburban, Cadillac Escalade, GMC Yukon and Lincoln Navigator.
