Introduction of the New A-Class, Model Series 176
b
Vehicle concept
The A-Class in model series 176 is based on a new
concept, which differs fundamentally from the
previous A-Class model series 169.
The transversally installed engine is no longer
mounted above the front axle, but ahead of it. The
multilink rear suspension provides high responsive-
ness with high driving safety and high comfort.
Numerous special equipment options such as
driving assistance systems make the new A-Class
especially comfortable while also enhancing its
safety level.
Dimensional concept
The change in concept is particularly apparent
when the vehicle dimensions are compared with the
predecessor. The vehicle length has been extended
by 409 mm, the wheelbase by 131 mm. The width
of the vehicle has grown by 16 mm while the vehicle
height has been reduced by 160 mm.
