Engine and Transmission
Due to the new regulations, a completely new engine was used for the 1938 season. The M154 was a 3000cc supercharged V12, attaining an output between 425-474 horse power. In 1939, the 2-stage supercharged version of this 2,961.54 cc V12 engine (67.0 x 70.0 mm) recorded a test bed power of 476 BHP (483 PS) at 7,800 rpm.
To compensate for the smaller engine compared to the W125, the W154 had an extra gear with a 5-speed manual transmission. The first gear was protected by a latch to avoid being engaged accidentally.

Famous quotes containing the word engine:
“The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,—unteaches him.”
—Ralph Waldo Emerson (1803–1882)
