About Your Car

I am fascinated one of the megabuck sedans comes up for makeover because manufacturers use this opportunity toshowcasegroundbreaking for the first time. I and my technologicallyinquisitive (known by less enlightened like my wife, ascar have witnessed the introduction of extraordinaryautomobiles over the past 5

We enjoyed itwhen we pored sleek all-aluminum Audi A8, and when we tried to decipher the on the new Mercedes S-Class. Last we all pondered the conundrum of how Lexushadtransformed the quiet LS 400 into the even quieter LS 430. It isno that we applaud the fanciful TV ad envisions the Infiniti Q45outfitted technology that turns green as an apt metaphor for the state of technology.

Even with the expectations I had going in, this all new BMW blew me awaywith the massive of revolutionary technology that it to the luxurycar battlefield. All indications are the7-Series is the vehicle that prove that we ain’t nothing yet . It looks like the at BMW have succeeded in maintaining vehicle’s place atthe top of automotive journalist’s list of to buy when I hitthe Lottery. of us even have the color and picked out,just in case.

The is redesigned from the pavement up a new 4.4 liter V8 engine, the world’sfirst automatic transmission and anall-aluminum with an optional Dynamic system that provides for suspension control. And that scratches the surface. The wizards at BMW completely rethought the way a driver interact with acar, in what they call which encompasses a number of innovations for the human-machineinterface.

Where to Well, people who would a Bimmer aregenerally more astute than the average car so I will get a bitmore technical usual for this article and with the marvelous new V8 engine.

This all-new design fully variable,computerized management of the system. The camshaft timing through bi-VANOS . a method the intake and exhaust cam timing in variable increments throughout engine speed range. But the news here is Valvetronic, a BMW design that regulates the of the intake valvelift from closed to fully opened.

This, says BMW, is a leaprivaling the industryswitch from to fuel injection or the jump points and condenserto electronic

What makes this so is that when you step on the gas youare no longer controlling the plate. Instead, engine iscontrolled by the Valvetronic system by varying the amount of intakevalve based on how hard you step on the There is still athrottle but it is only used as a failsafe or for diagnosticfunctions.

Under normal the throttle plate is held open, whichmeans that is no longer any vacuum in the intake Tocompensate, they have an engine-driven pump to provide for the brake booster.

Under driving conditions, this allows the intake valves to as little as half a millimeter,causing the mixture to enter the combustion through an almostpaper-thin valve This lets the fuel more fully, significantly combustion efficiency. Another is that controllingthe air flow at the combustion chamber instead of way up at the makes throttle response instantaneous because there is no stepping on the gas and engine response.

significant engineering advance is the use of the fullyvariable intake manifold. the intake runners to a specific efficiency at a specific rpm range. By the length instages, (many engines have two stages, have three) you can improve atmore than one rpm range, but gives you peaks and dips in the curve.

This engineeliminates the and varies the lengthsmoothly between long and full short, optimalefficiency and smooth power throughout the full rpm range.

TRANSMISSION: The automatic transmission in the new 7 a number of industry firsts. It is the six-speed automatic transmission and the with shift-by-wiretechnology. There are no connections between the shift andthe transmission. The unit is to an unusual torque converter disconnects the engine from the when the vehicle comes to thus improving fuel and eliminatingany undesirable creep

this transmission is a model Instead of the usual floor there is a column shift behind the wheel. Well, of. The lever isreally an electricalcontrol a small display in it. Simply the lever up for reverse,push it down for or push it in towards the steering to engage park.

Sportsminded will have to wait for the manual shift control. The adds an EPA mileage penalty due to the way the test has to beconducted. In the real there is no such disadvantage, but thebureaucracy is the bureaucracy.

For now, is a limitingmode where you will be to control the top gear the unit shift toby using buttons on the steering wheel rim in to select L5, L4, L3,L2,or L1.

SUSPENSION: The system confirms BMWs position as builder ofthe driving machine. If this car as good as it looks onpaper, and no doubt in my mind that it then this automobile the benchmark for the foreseeable future.

The system isall-aluminum in order to unsprung weight to a minimum. includes the wheel and tire, rotor and caliper, and the suspensionarms: in words, all the components that up and down with the road and are not supported by the springs. The lighter thesecomponents keeps the tires in contact with the road by the inertia thatcreates a bouncing on rough surfaces.

By avoiding tendency ofheavy suspension to bounce, the BMW maintains more tire grip.

Air suspension is on the rear axle as an option and to keepthe car level regardless of Another suspension feature, RollStabilization, compensates for body by adding active suspension to themix. A third system, provides variable shock under computercontrol for no-compromise and handling over a variety of conditions.

EDC is available as part of an optional Ride Package and offers of the shock absorbers from soft to full firm.

The interesting of these suspension has to be the Active RollStabilization systemwhich of front and rear active bars. These are sway that are cut in half and attached center to a control unit uses hydraulic pressure to areverse-twist to the bar under computer in order to compensate for body during turns. Thisproduces flat cornering up to about a G with no compromise to thesuperb

Beyond that, the system some lean to creep in so feel the feedback and realize you are approachingcornering limits. Yes, are still limits. Sorry BMW hasnot yet found a way to disobey of physics.

INSIDE: The interior of the 7 is sumptuous as you would expect in a for upwards of $70,000. Two different of wood are available: silk cherry and optional high-gloss Eachwood is available in a light or finish depending on interior

With careful attention to the of the controls and readouts, the 7challenges established conventions of driver-vehicle Yes, the steering wheel,the gas the brake pedal and the directional are exactly where you would to be. So, what is different?

For one thing, you can this car without a key. I should say, without the Electronic key from your Once you configure the 7 with Access, you can simply walk up to the car and one of the outer door handles.

action sets off a wireless between the car and the key in your pocket. you have the correct key, you can just open the door, sit the wheel and press the Start/Stop to start up; then tap the transmission down once to engage and off you go.

Glancing around the cockpit, the thing you are apt to notice is the large panel in the center of the dash. combined with a joystick-likeController just ahead of the center is the IDRIVE Control Center can control hundreds of functions intuitiveness. Moving the controller back, right, left,or in one of diagonal positions will one of 8 function areas.

Bear in that I am describing a European model and the US car mayhave differences, but the should be the same.

The first are the most commonly used and are by moving the controllerNorth, South, or West. The remaining functions are by movingthe controller diagonally. The 8 areasare:




GPS Navigation

on-board computer


radio and player

Climate Control

air heated seats


to GM’s OnStar system

maintenance schedules, checks

some hand-holding on how to use the system


controls for customizing preferences like date time

English or etc.

Once you have a function, the display switches to the screenfor that section. You rotate the knob and pressit as to perform a task. Wait, it better.

TheController knob Force Feedback technology to the more expensivecomputer game that let you experience feedback in the Forexample, if yougo into a while flying Flight you feel vibrations andincreased on the stick until you crash the barn,at which time the feels like it will out of your hands. Yeah, kind of Force Feedback.

In case, it allows the controller to a differentfeel depending on the function you choose. For instance, if youselect the system balance control, you feel a detent in the centerposition and resistance as you rotate the knob to end of therange. This technology many different kinds of with a distinctive touch for you to perform tasks by feel keeping your eyes on the

In typical BMW fashion, you can select an assortment of seating options for the new 7. For the you can choose the basic 14 way driver memory and 12 way passenger seats, or you can opt for the comfort seat (standard on the with power adjustments for the bolsters as well as the angle for the top of the seatback. For the rear passengers, you the basic unit or the comfort seats with memory and power adjustments. Two other that are available for the seats are ventilation and seat heating rapid heating and balance

The cruise control system has an new feature. You canpre-select common in advance (like 30, 55 or 75 mph), just press a button to the carreach and hold that

Some other new features are notable include:

a pushbutton brake that electrically the mechanical parking brakes the engine is off, or the normal brakes when the engine is

hydraulic door checks keep an open door at any point along its path, not at a couple of preset positions.

sunblinds in the rear doors

Safety: No self-respectingcar company introduce a top-of-the-line model some new safetyfeature to crow and BMW is no exception. Theirs is called Safety Integrated System and is an all-new bus system for theintelligent of airbags, belt latch and active headrests. The system is to activate the rightairbag with the intensity at the right time.

And there are plenty ofairbags to from the tubular head air bag has been refined with of a curtain that will occupants from flying and debris,to front and rear airbags and the world’s first airbag for the driver. Other featuresinclude: adaptive belt limiters, active headrests to againstwhiplash and a new seat structure to side impact protection.

Of BMW has not neglected the all-important sound They will use state-of-the-art audio signal processing on theLOGIC7 concept and operated through the Control Center. HiFi Professional speaker consists of a midrange speaker center of the instrument panel, six speakers in the four doors the package shelf at the rear and two woofers beneath the frontseats.

two woofers have a 1.1 … and are to the hollow frame rails.

these cars are out of reachfor working stiffs, so why should the public beinterested? Just so can eat their hearts out? Of The average person can consider a look into the future to a when thetechnology introduced on luxuryyachts filters down to affordable cars.

Remember: air powermirrors, heated seats, headlights, ABS brakes and traction wereonce available only on models that were the reach of middle-classfolks. Now, features are offered on so-called carsand, in some cases, are equipment.

Okay Mercedes, is due for a freshening soon. Let’s see you can come up with totop new Bimmer. Ever go whale

It’s great fun to watchas whale tries to outdo his at jumping the highest or making the splash when comingdown. a great time to be a car nut.
