BMW inline six-cylinder petrol engine. The most innovative power unit
of our time: Everything questioned. Everything answered. An engine
blessed for success. The BMW inline six-cylinder engine used up until
now has been an extremely successful power unit - sporty, economical
and smooth-running with a throaty exhaust sound. Weighing just 171 kg,
the M54 is also one of the world's lightest six-cylinder engines and a
total of 1.4 million units have already been built. Further
development conceivable but inefficient. Consequently, the M54 engine
would have been an ideal candidate for further evolutionary
development. This had happened consistently over its lifetime and
consequently led to the BMW M54 engine achieving its cult status and its
pole position in the market. However, BMW customers expect great
things from a new engine, and so do BMW engineers. With ambitious
performance and fuel consumption targets in mind, as well as the
precedent BMW has set in innovative engine construction, these
engineers have developed an entirely new concept - the NG6 range of
six-cylinder engines. An upgrade of the existing M54 unit according to
state-of-the-art technical specifications would have resulted, inter
alia, in the engine being 14 kg heavier. After several technical
modifications to the M54, which consistently increased performance,
bringing about a drop in fuel consumption at the same time, the demands
of the future could only be fulfilled by implementing fundamentally new
concepts offering a high technological potential. I The new engine had
to be radically different, leaving only BMW's signature inline
six-cylinder arrangement unchanged. A look at the specifications:
Conflicting objectives can only be solved using new technologies. In
view of the high standards set at BMW, new developments always take a
giant leap into the future. The company has demonstrated its ability to
redefine benchmarks time and time again, particularly in the field of
engine design and performance, and the new NG6 engine is no different.
Living up to its raison d'etre of Sheer Driving Pleasure, the basic
requirements placed on every new BMW engine are increased power and
higher torque. However, the BMW has always been environmentally
conscious and, at the same time, both fuel consumption and CO2
emissions have to be lowered. Moreover, on a medium-term basis, BMW
innovations pertaining to an individual component or aggregate become
the technological benchmark of the entire company and its products,
spanning all series, markets and client groups. The BMW innovation
VALVETRONIC, for instance, is already featured on all BMW four-, eight-
and twelve-cylinder power units. For this reason it was only natural to
apply this technology to the six-cylinder engine. However, at the same
time, the new NG6 power unit had to retain the M54's class leading
weight and size. Optimum power density could only be realized through
the utilization of new technologies and materials, incorporating a
modified basic design and a myriad of innovations for systems,
ancillary units and components.
