2006 BMW M5
by Cordell Koland
You¹ve seen those
ads on late-night cable selling 'girls-go-wild' videos.
If I had to come up with a
slogan for the new fourth-generation
BMW M5, it would be, BMW
Engineers Go Wild.
The specfic engineers in
question work for the subsidiary BMW M
GmbH, a separate company that
must be a perpetual spring break for technical wizards. BMW M engineers have taken the
respectable
5-Series sedan and stripped it
of engine, transmission, suspension, and wheels and replaced them with the wildest, most flagrant
upgrades possible.
For example, the M5
features a 500-horsepower five-liter V-10 engine,
the first for BMW in a
production automobile. This engine unveils incredible performance: acceleration registers zero to
60 mph in 4.5 seconds and attains
a top speed of 155 mph. In full launch mode it will
pin you to the seat back.
The M5 also features a
seven-speed sequential manual transmission,
a special suspension,
compound, cross-ventilated brakes, extra-wide 19-inch wheels and high-performance tires and an unprecedented
number of electronic controls. The
body is tricked out with modified
front and rear aerodynamic tweaks, special M 'gills' behind the front
wheel arches, a slightly lower stance and four tailpipes.
And while the M5 speed
and power is impressive, it's handling seems
even more remarkable. No
matter how fast I threw it around a corner,
I felt I was just dipping into
its road holding prowess.
However, raw performance
is not the whole story with the M5. Over
the years, my wife has become
an acute observer of things automotive
and my personal reactions. I
was surprised when she said this was the
first BMW M that I haven't
felt the urge to buy. She's right. I have
lusted over every vehicle in
the long-running M series and having
caught her in a moment of weakness actually bought a fast M.
Here's my problem. The
M5 has a very complex interface with the
driver that gets in the way of
the driving experience. There are
computer controls for the
engine, transmission and suspension as
well as BMW's iDrive. Let's deal with iDrive first.
The essence of the
iDrive is a controller, a center console-mounted
joystick, and display
screen. With iDrive, you select from hundreds of
choices via a menu
system that accesses the navigation, audio, and
climate controls. You move the
controller in one of four directions, up, down, left, right, that correspond with one of the
car's basic electronic systems, such as entertainment or the navigation system.
When you've found the right function,
you push the controller down to make a
selection.
I thought I had mastered
iDrive. I even wrote a feature on iDrive for a
computer magazine.
Sometimes I could easily access the desired function.
Sometimes I could not.
Nevertheless, the system is complex and slower
in actual operation than just
twisting a knob to access an audio or
climate-control function.
As for control of
mechanical components, the complexity of the transmission interface is a testament to the engineering
mind. The
gearbox offers 11 computer
shift maps that manage the engine
speed and the quickness of the gear
change. Five of these programs
can be chosen in the automatic mode and six under manual operation.
In actual operation, I
found the fastest settings to be somewhat harsh
or abrupt under some
conditions. On the other hand, the slowest setting seemed as if the transmission case was filled with
molasses. While a
good driver cannot shift as
quickly as a sequential manual, I think he or she could make a gear change more smoothly.
Overall, BMW says that
the driver has 279 combinations of control settings to chose from that manage throttle
response, transmission, suspension and electronic stability control.
The BMW M5 is often
referred to as a four-door sports car. But in my
dictionary, a sports car
is a simple tool that reduces the equation to a
vibrant motor, a firm
suspension and fast, direct steering. You turn the
key and away you go,
concentrating on the road ahead, the steering
wheel and the gearbox. The BMW
M Coupe in my garage meets this definition. Driving, the M5 by contrast seems more like piloting a 747
or the NASA Space Shuttle.
