The Mercedes-Benz M119 was a V8 automobile engine produced from 1989 through 1999. It was available in 4.2 L; 5.0 L; and 6.0 L displacements. It was a double overhead cam design with 4 valves per cylinder and variable valve timing on the intake side. It was replaced by the 3-valve M113 starting in 1997.
The M119 differed from the M117 in the following ways:
- The engine block uses asbestos-free gaskets and has better oil flow
- The cylinder head is now a 4-valve aluminum unit with dual overhead camshafts
- The connecting rods are forged and enable cooling of the pistons with sprayed oil
- The pistons are iron-coated cast aluminum
- An improved vibration damper system is used
- The aluminum oil pan has bolted-on oil baffles to prevent foaming of the engine oil
- The intake camshaft timing is adjusted hydro-mechanically up to 20°:
The 4.2 L (4196 cc) version (M119.975) produced 279 PS (275 hp/205 kW) at 5700 rpm and 295 ft·lbf (400 N·m) at 3900 rpm. Japanese versions produced 285 PS.
The 5.0 L (4973 cc) version produced 326 PS (322 hp/240 kW) at 5700 rpm and 354 ft·lbf (479 N·m) at 3900 rpm. Later engines had the full throttle enrichment removed and power was a little less, closer to 320 PS (315 hp/235 kW).
The E50 AMG M119.985 produced 354 PS (260 kW; 349 hp) @ 5,550 rpm and 481 N·m (355 lb·ft) @ 3,200 rpm.
The 5.0 L M119 was also adapted for racing with the addition of two turbochargers. It won the 1989 24 Hours of Le Mans in the Sauber C9 and was further used in the Mercedes-Benz C11 before being replaced by the M291 3.5 L Flat-12 in 1991.
The M119 found in AMG models produced around 381 PS (280 kW; 376 hp) to 415 PS (305 kW; 409 hp) and upwards of 580 N·m (428 lb·ft) of torque.
