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:
“Industrial man—a sentient reciprocating engine having a fluctuating output, coupled to an iron wheel revolving with uniform velocity. And then we wonder why this should be the golden age of revolution and mental derangement.”
—Aldous Huxley (1894–1963)
