The midsize E-Class is the core of the Mercedes lineup. As a result there is a wide model range to cover most needs. E-Class sedans are equipped with a 208-bhp 3.2L I-6 turbodiesel (E320 BLUETEC), 268-bhp 3.5L V-6 (E350), and a 382-bhp 5.5L V-8 (E550). A 4Matic option provides AWD traction. Performance enthusiasts will prefer the E63 AMG with its 507-bhp 6.3L V-8. Transmissions include a 5-speed (E63 AMG and 4MATIC models) or 7-speed automatic. Optional "designo" packages combine interior and exterior trim in a color coordinated theme.
