Mercedes E320 Bluetec

The basic styling of the E320 Bluetec is shared across the entire mid-size E-Class line. And it is virtually identical to its gas-powered sibling, the E350. The classic elegance of this automobile comes from its flowing lines and understated design. But subtle cues like accentuated fender flares and a body-side crease do hint at the car’s performance attributes.

Upfront, optional bi-zenon headlights are offered. And the car rides atop standard 17-inch twin-spoke wheels.

Overall, the E320 Bluetec has the smart and sophisticated looks that affluent professional-types will appreciate. And even if they aren’t actually socially conscious, the Bluetec badging will allow them to look like they are.
