Audi A3: Hot Hatch Meets Smooth Cool German

Despite today s never-ending talk about globalization and the merging of world cultures, German cars still have a personality all their own. But like most strong personalities, the distinct flavor of Teutonic automobiles isn t a favorite with everybody. While the typical German car s smooth, refined manners are impressive, such machines can seem a little too slick feeling for some -- they tend to be a bit isolating, sterile, chilly.
Count me among believers of the latter. I generally like cars to have more soul than the usual Bahn-stormer delivers. But that s why I found the new Audi A3 to be such a pleasant surprise. It s as friendly feeling as a Japanese sports sedan, without giving up the sense of precision and refinement that s the hallmark of machines from Audi and other German makes.
Slipping into the A3 s cabin, you find it to be noticeably smaller than its A4 sibling, but not dramatically so. Surrounding occupants are quality-feeling black plastics of various finishes, offset by a sprinkling of aluminum here and there. Although not opulent or expensive feeling, the A3 s furnishings are sophisticated and pleasing. They convey a sense of thought and care in their design.
Likewise for the optional leather upholstery, which has a taut, quality feel. The seats are supportive and comfortable. There s decent room for tall individuals up front. In back, leg- and head-room are a bit snug for six footers, but not painfully so.
Firing up the turbocharged 2.0-liter four yields a smooth, precise purr, which elevates to an almost exotic rip as rpms get into the upper half of the range. That transition is appropriate, mirroring the engine s switch from somewhat lopey feeling off the line, to a surprisingly strong midrange champ that has more gusto than its 200-hp rating might imply.
Indeed, a look at the specs shows why -- this engine s full 207 lb ft. of torque is available at just 1800 rpm, giving it a gutsy feel that s quite entertaining. Although the A3 will be offered with a 250-hp V6, the four is plenty enjoyable.
Somewhat less enjoyable, however, is the 6-speed sequential-shift manual transmission. It proved to be a mixed bag. The steering-wheel shift paddles were intuitive and effective for manually controlling shifts. Likewise, the transmission s upshifts under hard throttle demonstrated impressively quick action without any sort of jerkiness. But automatic-mode downshifts were a trifle sluggish and upshifts often came early, leaving the engine to lug along in what felt like too low a gear.
Nonetheless, such quibbles don t dampen the fun appreciably and the A3 is good for plenty of excitement on twisty roads. Compared to most German sporty cars, the A3 s steering is lighter and more communicative -- dare I say even a bit soulful. Complementing this is the A3 s competent, confidence-inspiring handling. Not surprisingly, grip runs out front-end first on this FWD machine, so charging into tight turns can bring on some plowing understeer. But it s not a major handicap, and it s certainly no worse than most rivals in this respect. Firm damping controls body motion well and the A3 s brakes are powerful and easily modulated, capping off a package that s good for plenty of sport-driving fun.
The only significant downside I found to the A3 is its price. Although prices start at an attractive $24,740, our A3 2.0T test car stickered for around thirty large with a few typical options. While that s not exactly highway robbery for a machine this competent, it s enough to probably send some potential A3 buyers toward rival premium subcompacts.
But after looking around, a lot of those people will probably come back to considering the A3. It s a nice blend that s easy to fall for -- small but practical, lively yet sophisticated, Teutonic but eager. Plenty of other cars would do well to emulate its virtues.

Toyota Ranked 6th in Fortune Global 500 List

Toyota Motor Corporation has made it to the list of Fortune s list of world s 500 largest companies by revenue for 2006. Toyota was ranked 6th for this year which is two notches ascent from last year s 8th ranked.
The producer of top-of-the-line Toyota Camry parts, Toyota Motor Corp. was the only Asian company that made it to the top 10 of Fortune Global 500 rankings. Toyota s revenue of $204.75 billion has qualified it for the 6th position.
Toyota s revenue has grown by 10 percent over the previous year and is expected to grow continuously for the coming years.
Aside from Toyota, the US retail Wal-Mart Stores Inc. has returned from the top spot from being second the previous year with a revenue of $351.14 billion up by 11 percent.
Exxon Mobile Corp. still from US came second with revenue of $347.25 billion followed by the British-Dutch oil titan Royal Dutch Shell PLC with revenue of $318.85 billion.
In fourth position was Britain s BP PLC with $274.32 billion revenue followed by General Motors, the world s largest automaker of United States with posted revenue amounting to $207.35 billion.
The total revenues of the companies included in the Fortune Global 500 list came to $21 trillion up by 10.4 percent as compared to 2005.
As expected six of the top 10 were oil companies with three automakers and a retailer. Banks and brokerage firms have also advanced in their rankings baked by a global boom in merger and acquisition activities.
There were a total of 67 Japanese companies that made it into the Fortune s list down by three from the previous year which is attributed to the depreciation of yen against some of the world s major currencies which reduces their revenues in dollars.
Japan has the second largest number of companies on the list seconded by United States which has 162 companies. The combined revenues of the US companies included in the 500 list accounted for more that one-third of the total revenues of the Fortune Global 500 companies.
China has also 24 companies that made it into the Fortune s 500 list, up by 20 from the previous year and the second highest number in Asia following Japan.
Among the Japanese firms that made it into Fortune Global 500 list are Honda Motor Co. which ranked 37th with $94.79 billion revenue; Nippon Telegraph and Telephone Corp. ranked 40th with $92 billion revenue; Nissan Motor Co. on the 45th place with $89.50 billion revenue; and Hitachi Ltd on the 48th place with $87.62 billion.

Plugin Diesel Power

With ever rising fuel costs and efiiciency now a major forcus of car manufacturers world wide and new product has been developed that can make all the difference for diesel vehicles.
The mass-produced diesel car engine generally has a number of shortcomings that are the result of the necessity to meet a wide variety of service conditions and realities, such as variations in manufacturing tolerances, fuel quality variations, climatic conditions, and inferior maintenance. As a result, the off- the-shelf characteristics of a standard diesel engine offer significant scope for improvement and, as has been shown by power and torque curves obtained from dynamometer tests, poor low speed response and mid-range "flat-spots" can often be eliminated, with a resulting improvement in overall performance which doesn t just mean going faster. So "tuning" is not all about raising power and torque output, (although this is usually also a pleasant end result!) but equally about optimising the efficiency of the engine. Improved efficiency means improved economy and better fuel consumption.
One of the reasons why the diesel engine has great advantages over its petrol counterpart in terms of response to tuning is the key factor of "excess air". Try to tune any petrol engine by offering it more fuel and it soon becomes breathless, as it runs out of oxygen with which to burn the extra fuel. The only way to overcome this is to persuade the engine to burn more petrol at higher engine speeds, where more air/oxygen can be ingested. So generally a tuned petrol engine has to rotate more quickly to produce extra torque and power, and in the process becomes a more temperamental and frenetic performer. But most diesel engines and we are inevitably talking today of turbo-diesels are able to ingest far more air than is needed to burn the injected fuel. So they respond eagerly to the offering of carefully chosen modest amounts of extra fuel by intelligent re-programming - and in the process usually actually operate at higher efficiencies!
The ready availability of excess air at all engine speeds means that the tuned diesel engine usually produces its extra performance throughout the rev range and, as a result, the response is improved in all driving conditions not just when maximum power is demanded. So a tuned diesel becomes an even friendlier and more willing beast, often becoming smoother and more flexible so it will pull a higher gear, and often deliver better fuel economy than a standard engine because it s actually more efficient!
How does it work?
The operation of today s electronic injection diesel engines is masterminded by the engine s ECU which, according to requirements, sends constantly varying signals to the fuel injection unit, as instructions to deliver a certain amount of fuel at any instant. Electronic tuning uses any one of a number of different systems to modify this signal in such a way that, throughout the engine speed range and according to power demands, the fuel injection volume is beneficially enhanced. But it s particularly useful if there s potential to actually adjust these modified instructions according to individual needs and particularly if an engine is being tuned to an owner s specific requirements.

VW Window Switch---Window Control at the touch of a button

The innovations of technology has given rise to the mainstream usage of the power-window system in an automobile. In a Volkswagen vehicle, one feature that spurred its sales is its power features, in which the windows are included. In the way, a driver or passenger would not have to exert more effort in opening the window through the window knob. It works to the advantage to the driver since the driver won t have to loosen its attention on the road ahead. To this convenience, the one that starts to regulate the mechanism is the VW Window Switch.
The VW Window Switch starts out the operation of a rather compact window motor, enabling the window glass to go up and down. This eliminates the manual use of the window handle. It basically utilizes its electrical contacts to complete the circuit of the electricity that activates the window motor. This makes the motor rotate its series of gears. And such activity, it pushes the window glass up or down.
Depending on what Volkswagen vehicle containing a window switch, it comes in three types. The lever switch, which is often the most recommended to owners with children who ride with them, does not permit the window to raise immediately. It has to be pulled up first in order to be raised. The hazardous situations when children often marvel at taking their heads out when traveling is taken into account, especially if the window switch is accidentally pressed. As for the rocker switch, the window glass will go up instantaneously. One has to push it forward or backward just to make it work.
In most vehicles of today, a simpler way of wiring is being done through a technique called Multiplexing. There is this so-called module containing at least one microprocessor that consolidates inputs and outputs for an area of a car. The driver s-door module monitors all of the switches, including the VW Window Switches. This works when a driver presses the window switch, and then the door module closes a relay which activates the window motor. If the driver presses the switch to adjust the passenger-side mirror, the driver s door module sends a packet of data onto the communication bus of the car. This packet tells a different module to energize one of the power-mirror motors. In this way, most of the signals that leave the driver s door are consolidated onto the two wires that form the communication bus.
Make it a point that the window switch works efficiently. If dirt penetrates along the gears and other components, chances are, the VW Window Switch will malfunction. It must, therefore, be checked regularly and have maintenance check-ups be done accordingly. There are instances when a corroded toggle can be revived via the contact cleaner. It won t it would not be true in all cases. In replacing the VW Window Switch, it is as easy as a do-it-yourself scheme. Unplugging and unscrewing the window switch will have the unit replaced immediately. The hard part is removing the trim panel the switch is installed upon.
