Performance
The new M Class has given every buyer increased performance with the two new
engines for which the new M Class vehicles are named. The ML350 comes with
the new 3.5 liter V6, and the ML500 packs the new 5.0 liter V8. The new 3.5
liter V6 uses a die cast aluminum alloy block, with cast aluminum alloy
cylinder heads, each of which carry its own intake and exhaust camshaft
which with the assistance of a variable valve timing system, help to operate
their share of the twenty four valves, set in the heads at ninety degrees to
the face of the cylinder. The 3.5 utilizes an advanced air intake system
which draws air through a dual stage magnesium resonance intake manifold,
with electro pneumatic turbulence flaps at the front end of the intake
plenum which controls air intake speed at varying ranges for a more precise
air to fuel mixture. This setup helps to increase low end horsepower and
torque, as well as increasing throttle response across all of the RPM
ranges. To match all of this air intake, the spark is provided by means of
a single high energy ignition coil and one spark plug per cylinder, which
are only slated to be changed every one hundred thousand miles. The fuel is
introduced by means of a electronically controlled sequential multipoint
fuel injection system, which is integrated with the ME 9.7 engine management
system; which when combined allow for individual control per cylinder of
fuel insertion, ignition timing, and antiknock issues; all of which yield a
10.7 to 1 compression ratio, requiring no less than ninety one octane
premium gasoline. This new V6 setup with the variable valve timing and
intricate spark and induction system allows the small, efficient engine to
build an impressive two hundred and sixty eight horsepower at six thousand
revolutions per minute, and two hundred and fifty eight pound-feet of torque
at five thousand revolutions per minute.
The second vehicle in the new M Class lineup, as mentioned is the ML500.
The 5.0 liter V8 in this model is so similar to the V6 in construction that
it is almost simply a bigger version of the 3.5 liter engine. The 5.0 liter
engine comes with a die cast aluminum alloy block, with cast aluminum alloy
cylinder heads, each of which carry its own intake and exhaust camshaft
witch with the assistance of a variable valve timing system, help to operate
their share of the twenty four valves, set in the heads at ninety degrees to
the face of the cylinder. This 5.0 also utilizes an advanced air intake
system which draws air through a dual stage magnesium resonance intake
manifold, but without the turbulence flaps, yes still helping to increase
low end horsepower and torque, as well as increasing throttle response
across all of the RPM ranges. The spark of this 5.0 liter is provided by
dual high energy ignition coils and two spark plugs per cylinder, which are
only slated to be changed every one hundred thousand miles. The fuel is
introduced by means of a electronically controlled sequential multipoint
fuel injection system, which is integrated with the ME 2.8 engine management
system; which when combined allow for individual control per cylinder of
fuel insertion, dual phase ignition timing, and antiknock issues; all of
which yield a 10.7 to 1 compression ratio, requiring no less than ninety one
octane premium gasoline. This new Mercedes V8 setup in the new ML500 gives
the driver control of the road with a commanding three hundred and two
horsepower at fifty six hundred revolutions per minute, and three hundred
and thirty nine pound feet of torque at forty seven hundred and fifty
revolutions per minute.
