V6-powered Mercedes-Benz E400 sedan debuts for 2018

When the all-new Mercedes-Benz E-Class sedan debuted last year, the only available model was the E300 with the 2.0-liter turbocharged inline-four. That model was followed by the V6-powered E400 wagon and the powerful E43 and E63 AMG twins as well as coupe and convertible variants.
