| Predecessor | M117 |
| Successor | M113 |
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°:
- 0–2000 rpm — retarded for improved idle and cylinder scavenging
- 2000–4700 rpm — advanced for increased torque
- 4700– rpm — retarded for improved volumetric efficiency

4.2
The 4.2 L (4,196 cc) version (M119.975) produced 205 kW (279 PS; 275 bhp) at 5700 rpm and 400 N⋅m (295 lb⋅ft) of torque at 3900 rpm. Japanese versions produced 285 PS (210 kW; 281 bhp).
Applications:
Mercedes-Benz 420SEC/ S420coupe/ Cl420
5.0
The 5.0 L (4,973 cc) version produced 326 PS (240 kW; 322 bhp) at 5700 rpm and 480 N⋅m (354 lb⋅ft) of torque at 3900 rpm. Later engines had the full throttle enrichment removed and power was a little less, closer to 320 PS (235 kW; 316 bhp).
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.
Applications:
The 5.0L 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 3.5L Flat-12 in 1991.
6.0
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.
The 6.0 L M119 replaced the M120 V12 in the CLK-LM race car, which then won every race in the FIA GT series, which ultimately resulted in the GT1 class being canceled.
For 1994 model year, there also limited AMG models for Japan which built or sold between October 1993 to September 1999 in left-hand drive. Installed engine was M119.970 which has 6.0 L (5,956 cc) of displacement, 380 PS (279 kW; 375 hp), and 59.1 kg⋅m (580 N⋅m; 427 lb⋅ft) of torque.
