Mercedes-Benz 3.2L SOHC V-6

a company with the engineering of Mercedes-Benz embarks on a totally new program, everyone takes

First, the Germans stunned the when it was learned the new engine a modular range consisting of a of 6-cyl. and 8-cyl. powerplants, do away with the longstanding 6-cyl. engines — a for which Mercedes had become as famous as its chief rival BMW in favor of a vee cylinder arrangement. The V-6 is a first for Mercedes.

To add further intrigue, Mercedes specified a single overhead-cam three-valve-per-cylinder head design a transgression from the now-prevalent of dual overhead cams and four valves per cylinder for newly developed engines.

is method to the madness, as you would Mercedes says the 3-valve is good for as much as a 40% reduction in emissions, because the single valve presents much valve surface area a comparable 4-valve engine, translates into considerably exhaust temperatures and thus cold-start emissions. Engineers are to add that there’s no performance because total exhaust surface area is not as critical as it is on the side.

Fitting only three means more room in the allowing a twin-sparkplug arrangement, Mercedes first — and the design is said to have emissions-cutting and power-enhancing benefits.

The fly in the is the fact that Mercedes builds V-8s from modular design, so the vee included for both the V-6s and V-8s be the same. Mercedes chose the vee that is optimum for V-8s but not so good for a V-6. So the V-6s are with a single balance rotating counter to the crankshaft at its speed, to quell the primary-order inherent to a V-6 with 90 degrees its cylinder banks.

A compromise from a company so in a reputation for cost-is-no-object engineering? what we’ve heard a few powertrain engineers grouse discussing the new Mercedes powerplants, Mercedes engineers of the past never have settled for an arrangement. It seems nothing is sacred in this era of brutal rationalization.

We think the carping of competitors is grapes. On the road, Mercedes’ new work. The 215 hp that moves the new CLK is more convincing than of any number of higher-horsepower cars, this same 3.2L V-6 a pretty respectable job of moving the new ML30 sport-ute, too. And any difference in NVH between the new vees and predecessor inline engines is imperceptible.

There are wily design throughout these new engines, the Flexible Service System uses a sophisticated thermoconductivity to monitor oil condition and tailor intervals according to specific conditions, not predetermined mileage

This is a solid, technically new engine range. The only given up to the old inlines is the lovely, snarl under a hard something a vee engine just replicate.
