As web browser why should we upgrade internet explorer 6 or migrate to other web browsers

Internet Explorer 6 (IE6) is a pretty old fashioned and much slower than other web browsers like Firefox, Opera, Google Chrome etc. This includes going from web page to web page, starting up the web browser, and downloading files from the web to your computer or laptop. Speed is very important if you like being able to do many things in a short period of time. This could be checking the weather report before traveling. Whatever it is speed is a key factor.

We can’t use internet explorer 6 in a tabbed interface mode, where other browsers have this feature. Except internet explorer 6, other web browsers places newly opened Web sites in a separate tab within the same browser window. This feature hugely decreases clutter on Windows taskbar. But in Internet Explorer, we have to open a browser window; a new icon appears in your taskbar. If we open twelve browser windows, and our taskbar will quickly fill by these twelve browsers. You can invoke a windows XP feature to collect icons from the same program to cancel taskbar clutter.

If we want to see the source code of any webpage then internet explorer opened it on notepad which do not highlights the tags and properties in different colors and weights, where other web browsers open source code on separate window or tab with this highlighting feature.



Internet explorer 6 does not support many features of modern webpage design methodologies. As an example, a modern web designer design a web template with very exciting and nice features using latest techniques and methodologies and then tested the template with Firefox, Opera, Safari etc. and find everything works perfect and feel satisfied of his job. But it became nightmare when he tested the template in internet explorer 6, because many features are nor worked and also showed the template odd looking. This is why many web developers blocked visitors to visit his website contents, if the visitor use internet explorer 6.

I think these are the sufficient reasons for upgrade our default web browser from internet explorer 6 or migrate to other faster web browsers like Firefox.

Audi Concept Study - Audi Q7 Hybrid Concept

The drive principle of the Q7 hybrid concept is a genuine technological world first: this unprecedented combination of FSI petrol direct injection unit and electric motor develops maximum power at minimum fuel consumption. The quattro four-wheel drive translates the engine’s impressive power into forward movement with maximum dynamism and safety.

Drive Concept: Dynamism and efficiency-the drive concept

The drive principle of the Q7 hybrid concept is a genuine technological world first. The combination of FSI petrol direct injection unit and electric engine provides maximum power – from minimum fuel consumption. The quattro permanent four-wheel drive translates power and torque into outstanding road performance and safety, thus making the concept study a genuine all-rounder complete with the qualities of a sports car. The Q7 hybrid concept accelerates to 100 km/h in just 6.8 seconds. The pulling power of this performance SUV is even more impressive – in 5th gear, it sprints from 80 to 120 km/h in precisely 7 seconds. Its fuel consumption is remarkable, too – it is 13% lower than that of the basic Audi Q7 model.

FSI petrol direct injection unit
The concept vehicle features a dynamic 4.2-litre FSI V8 engine developing 257 kW (350 bhp) and 440 Newton-metres. The advantage is that FSI engines are notably economical and generate more power and dynamism than conventional engines with indirect injection. The V8 was retuned for use in the Q7.

Elektric motor
The electric motor is integrated ideally into the driveline between the V8 engine and the automatic transmission’s torque converter. It develops 32 kW (44 bhp) at 200 Newton-metres. With the FSI engine connected up via a cut-out clutch, the electric motor can be used on its own or in conjunction with the V8.

Battery system
The electric motor draws its energy from a nickel metal hydride battery system that is housed at the rear of the vehicle, beneath the luggage compartment floor. This arrangement is superbly space-efficient, not intruding in any way on the entire volume of the occupant cell including the spacious luggage compartment.

If desired, the battery can drive the car in an exclusively electric mode at speeds of up to approx. 30 km/h. Coasting and brake applications feed additional energy into the system. Once the capacity limit is reached, the combustion engine cuts in unobtrusively to recharge it.

Compared with earlier generations of hybrid vehicles, the electric motor and the nickel metal hydride battery are distinctly light in weight – the study vehicle weighs just 140 kilograms, or seven percent, more than the basic version.

Intelligent Energy Management: Efficiency and dynamism

Complex control electronics take charge of coordinating the FSI power unit and the electric motor. They automatically decide how the drive components interact and respond efficiently to the driver’s wishes as indicated by applications of the accelerator and brake pedals, or operation of the tiptronic selector lever. The MMI shows the current status on the display.

Perfectly coordinated energy management
The energy management approach of the Q7 hybrid concept fundamentally recognises three driving modes, thus assuring the high efficiency of the drive system: the combustion engine or electric motor can operate as the sole power source, or they can combine forces in accelerating the vehicle. The petrol engine acts as the basic power source, as it simultaneously discharges energy to the battery.

“Boost”
If the driver wants to accelerate particularly swiftly, the electronics activate the electric motor, too. This new dimension of acceleration, known as “boost”, is entered automatically whenever the accelerator is pressed fully down. A comparison: the Q7 hybrid concept knocks 0.6 of a second off the time its V8 petrol counterpart takes to sprint from 0 to 100 km/h, and it accomplishes the sprint from 80 to 120 km/h, important for instance for overtaking, 2.0 seconds faster.

“Recuperation”
Whenever the driver applies the brakes or is driving downhill, the unit turns into an alternator and uses the energy released by such processes to charge up the battery. This process, known as “recuperation”, takes place unnoticed by the drive.

Energy-saving operation
“Creeping” and energy-saving operation: at speeds of up to 30 km/h, the Q7 can also be driven along exclusively by its electric motor if desired. If the vehicle is rolling in the hybrid mode without the accelerator being pressed or if it remains stationary for more than three seconds, the combustion engine is shut down.

The power of the sun
This innovative concept study not only manages its energy sources intelligently, but also uses the sun’s light to absorb additional energy. The expansive sliding glass roof, the open sky system, incorporates solar cells that can power the ventilation or air conditioning even when the car is parked - this function can in addition be activated by remote control.

The Audi A3 TDI Clubsport Concept: Intense TDI Power

Audi is unveiling a spectacular study in the compact class, in the guise of the Audi A3 TDI clubsport quattro. Based on the Audi A3, it sets new standards in terms of compact performance and efficiency. Its potent presence is a visible expression of the pioneering technology that propels this showcar: thanks to its extremely high-torque two-litre TDI engine, this sports car sprints from 0 to 100 km/h in just 6.6 seconds. The top speed is 240 km/h.

Exterior: Self-assured power pack

Its appearance expresses beyond all doubt what lies beneath its skin: the Audi A3 TDI clubsport quattro is a trendsetting bundle of energy. The stunning looks of this three-door model underscore its performance. Its special paint finish, with Ibis White roof and hood combined with Brilliant Red sides, adds to its air of confidence. The large white “8″ on each door is a reference to the year 2008.

Pure power
The designers gave this study vehicle a stunning, dynamic look that encompasses every tiny detail. The large DTM-look rear wing adds a visual reference to the world of motor racing and dominates the entire exterior of the Audi A3 TDI clubsport quattro. The struts of the exterior mirror housings are as if shaped by the wind. The bolted-on wheel arch extensions create a lasting impression. The striking sports car look is further underscored by a wider single-frame grille than on the production Audi A3, with struts in high-gloss black. The front bumper is adorned by large, angular air inlets.

Interior: Motor racing design, and comfortable too

The interior of the Audi A3 TDI clubsport quattro systematically adheres to the sporty styling of its exterior. All elements inside the car strikingly emphasise the spirit and sporty potential of the study. With its visual references to motor racing and jet design, the cockpit has a number of striking highlights. Combined with the anatomically shaped seats and the redesigned door panels and floor mats, it creates a sporty, comfortable overall impression.

Echoes of the Audi R8
Illuminated sill strips with the logo “TDI Power” greet the driver. Just like in a real racing car, they are greeted by an ergonomically shaped bucket seat – as is the front passenger. Special foaming also transforms the rear seats into spacious, comfortable individual seats. The classically open selector gate in aluminium accentuates the dynamic aura of the sports car’s interior.

The elegant, flat-bottomed steering wheel gives the driver precise control over where the Audi A3 TDI clubsport quattro goes. The scales of the instruments stand out in gleaming white. The air vents with their multi-position outlets have been given a jet design. Their dynamic look is complemented by classically sporty rocker switches on the centre console. The struts beneath the console are trimmed in leather. The monitor for navigation and entertainment and its control panel have been adopted from the Audi R8 supercar. To save weight, the door handles are hollowed out.

Drive Concept: Maximum dynamism and efficiency

Maximum efficiency – the entire concept of the Audi A3 TDI clubsport quattro follows this principle. Its two-litre TDI delivers the pulling power of a sports car. This power unit yet again demonstrates the high potential of TDI technology at Audi. The showcar is powered by an ample 165 kW (224 bhp) and 450 Nm of torque. It zips from 0 to 100 km/h in just 6.6 seconds. The top speed of this four-valve model is 240 km/h. And the study’s ultra-efficient four-cylinder engine already meets the limit values of the Euro 5 standard that is to take effect in September 2010.

Power for driving with poise
The engine’s maximum torque of 450 Nm starts right down at 1,750 rpm, in other words at rock-bottom revs – and makes the TDI a genuine built-for-fun driving machine. The sports engine’s power is acoustically underpinned by the newly developed exhaust system. With its variable resonance chambers on both tailpipes, it delivers a full-bodied, voluminous sound. The engine’s power is translated into locomotion by a compact, transversely installed six-speed gearbox with short shift travel. Its open selector gate is in aluminium. In combination with quattro four-wheel drive, it relays the engine’s power ultra-efficiently to the 20-inch wheels.

The sports suspension of the Audi A3 TDI clubsport quattro is easily up to the task of handling such power. Six-piston brake calipers and ceramic brake discs at the front and Audi magnetic ride technology for the dampers enable the driver to respond with lightning speed to every driving situation. With the driving dynamics system Audi drive select, they can adjust the throttle response and exhaust sound characteristics, the steering’s power assistance, the ESP control and the damper characteristics as desired.

Open for any adventure Audi Cross Cabriolet quattro Concept

Audi is introducing a new vehicle segment with its presentation of the Audi Cross Cabriolet quattro concept car: the two-door, four-seater car measures 4.62 metres in length and combines the genes of a typical dynamic soft-top convertible from Audi with the all-round qualities of a fully fledged SUV.

Exterior: Dynamic presence

Spectacular – a term which sums up the visual impact of the Audi Cross Cabriolet quattro painted in “Copper Sunset”, whether the top is up or down. After all, without the hint of a compromise, the concept car combines classic Audi Cabriolet hallmarks, such as the elegant fabric hood and aluminium A-pillar surface, with the undisguised dynamism of a sports car and the masculine presence of a genuine SUV.

Clearly defined and sporty

The longitudinally mounted engine and the basic chassis and drivetrain architectures of the Audi Cross Cabriolet quattro, which measures 4.62 m in length and 1.91 m across, are taken from the inventory of modules used in the current Audi A4 and Audi A5 model lines. The SUV-style height of 1.63 m with the hood closed marks the most significant difference to these relatives of the Cross Cabriolet quattro. In the side view, the shoulder line and dynamic line divide the vehicle body’s volume into a clearly defined sporty architecture. Within the pronounced styling of the wheel arches, the large 21-inch wheels with tyres of size 265/35 R21 send out a clear visual message.

Latest lighting technology

Behind its clear-glass headlight covers, the latest lighting technology can be seen: the Cross Cabriolet quattro is the latest Audi to be equipped with all-LED headlights, which also feature the characteristic strip of daytime running lights and the electronically controlled swivelling cornering light.

Innovative hood system

The fabric hood, which in just 17 seconds lowers itself fully automatically in a Z-fold behind the rear seats at the push of a button, is a trademark of all open-top Audi models. The rear loading solution is a perfect synthesis of convertible design and SUV functionality. When closed, the short stepped boot lid forms a continuation of the fabric hood’s coupé line. When it opens, however, it lifts up high to provide a surprisingly large opening, with the glass rear window automatically lifting up at the same time as the boot lid.

Interior: Sophisticated and ergonomically perfect

The interior of the Audi Cross Cabriolet quattro offers sophistication and ergonomically perfect solutions in all areas and with all its materials. The smooth and soft surfaces together with a gentle, natural blend of colours help to provide an atmosphere of absolute ease for the occupants.

Generously spacious

The driver and passengers enjoy the comfort of four spacious individual seats. On all four seats the air turbulence around the occupant’s neck is being counteracted. The seating is upholstered entirely in “White Stone” leather. The space available in the second row is unique for the convertible world: the legroom, shoulder space and headroom are unbeatable, even with the roof closed.

The operating concept

In addition to the instrument dials under the dome-shaped cowl behind the steering wheel and a central LCD colour display integrated between them, the MMI also supplies information via its swivelling flat screen. In addition to the familiar MMI terminal on the centre console, the Cross Cabriolet quattro has a touch-sensitive sensor field (touch pad). Like on a laptop, this can be used, for example, to move image sections of the map display. The touch pad is also capable of recognising and processing commands entered by tracing letters with your finger.

Infotainment: Precise and entertaining

Google Earth, the interactive, three-dimensional atlas of the world, is now available in-car. Audi has, for the first time ever, brought together the merits of the internet-based system Google Earth and its own built-in navigation system to create countless information facilities with user-friendly graphics. The audio system, too, benefits from internet connectivity by featuring an innovative radio system.

Intuitive: navigation system with Google Earth

The high-resolution display and photorealistic 3D maps provide a new dimension in intuitively understandable bird’s eye visualisations that are rich in detail. By connecting to the internet, it will be possible in future for traffic and weather information to be included and taken into account in planning your route. To enter a navigation destination, there is no longer any need to enter the address by hand. The driver can click on an image in the Google Earth user interface and be directed to the identified destination.

Individual: internet radio and Bang & Olufsen sound system

Leading the way in technical and acoustic quality is the sound system from Bang & Olufsen. It is a delight to the ear in the Audi Cross Cabriolet quattro, too. Its advantages really come into play in conjunction with digital sound sources: an innovative internet radio system provides access to the countless radio stations broadcasting over the World Wide Web. Simply by pressing a button, the user can give a positive or negative verdict on a music track. The system will thereafter only offer the user tracks and music styles that match his/her preferences.


Innovative: the intercom system

An intercom system is fitted to assist the occupants in communicating with each other. This eliminates the need to raise your voice – especially welcome when driving with the top down. Four microphones pick up the speakers’ voices and relay them at a subtly amplified volume via the vehicle’s audio system. The sound processor filters out background noise to give an extremely natural voice reproduction.

Drive Technology: Sporty driving dynamics

The 240 bhp three-litre TDI engine with ultra-low emission technology delivers sporty driving dynamics with exhaust emissions capable of meeting the EU 6 limits. The quattro permanent four-wheel-drive system and high-tech chassis with electric ride height adjustment are a recipe for driving pleasure on all terrain and in any curve radius.

Economical top-class athlete

The power output of the three-litre diesel engine with common rail direct injection is 176 kW (240 bhp) and its maximum torque is an impressive 500 Nm. It accelerates the Cross Cabriolet quattro from a standstill to 100 km/h in only 7.2 seconds and enables it to reach a top speed of 240 km/h – with fuel consumption averaging no more than 7.3 litres per 100 km. The 3.0 TDI is coupled to the quattro permanent four-wheel drive and an eight-speed automatic transmission. If the driver wishes to change gear manually, they can do so by using the shift paddles mounted on the steering wheel or use the selector lever with integrated control wheel.

The cleanest diesel in the world

To realise the ultra-low emission system, Audi’s engineers combined a whole package of innovative measures. A new common rail system with piezo injectors operating at a pressure of 2,000 bar, high-efficiency exhaust gas recirculation and further optimised turbocharging join forces to achieve a significant reduction in untreated emissions. The exhaust aftertreatment system operates with the additive AdBlue, small amounts of which are injected ahead of the DeNOx catalytic converter. Thanks to their extremely low emissions, Audi will from 2008 be able to sell its clean direct-injection diesels all over the world, even in the US states of California, Massachusetts, Maine, New York and Vermont, where extremely stringent emission limits apply.

Quattro drive

The Audi Cross Cabriolet always transmits its power to the road through the quattro permanent four-wheel drive. The key element in the quattro driveline is its centre differential. It is a purely mechanical unit and therefore responds without the slightest delay. In normal driving conditions, 40 percent of engine power is directed to the front wheels and 60 percent to the rear wheels, permitting sporty handling with a rear-driven emphasis. When needed, the differential redirects most of the torque to the axle that is achieving better traction.

Audi drive select

The Audi drive select system makes it possible to preselect three highly individual configurations for the engine, transmission characteristic and adaptive shock absorbers. The “dynamic” mode is the basic setting. The “sport” mode gives the Cross Cabriolet quattro an emphatically sporty driving feel. The shock absorbers are set firm, the engine responds more spontaneously to the throttle and the tiptronic transmission’s shift points move higher up the engine speed range. If the driver switches to the “efficiency” mode, the engine and S tronic respond gently – the perfect answer to relaxed driving with high potential for effectively lowering fuel consumption, and therefore emissions too.

Electric ride height adjustment

As a true SUV, the Audi Cross Cabriolet quattro displays impressive off-road talents. These include its innovative electric ride height adjustment, which varies ground clearance by a total of 40 millimetres at the touch of a button. The height of the vehicle body can be adjusted to make getting in and out that bit easier and also – as already seen in the Audi Q7 – the rear can be lowered separately for easier loading of the luggage compartment.

AUDI R8 V12 TDI concept: The Genes of the Winner

Audi is presenting a revolution in the top class at the Detroit Auto Show 2008 – the first 12-cylinder diesel engine in a high-performance roadgoing sports car. The V12 TDI with a displacement of six liters powers a concept car based on the Audi R8. This unit generates a huge 500 hp and 1,000 Newton¬meters of torque.

Exterior: Powerful and elegant

The R8 V12 TDI concept with matt “Grace Silver” bodywork looks even wider and more resolute than the core model. It shows its potential through its muscular proportions, accentuated wheel arches and even larger air apertures.

Focused on aerodynamics

The aerodynamics experts at Audi have done their work so thoroughly on the study car that, as an added benefit of its elegant shape, the body actually generates downforce – unlike many other sports cars. This aids directional stability at high speeds. It is achieved partly by means of an extending rear spoiler that is much larger than on the production version, and also thanks to the fully clad diffuser underbody. Two large-format diffuser apertures in the rear bumper demonstrate just how much aerodynamics dictate the shape of the study vehicle.

Large glass roof

One new aspect is the glass roof of the passenger compartment with two large transparent sections. These, together with the glazed engine compartment behind, create a radically new formal element. The unmistakable NACA duct in the middle of the roof is a functional detail that is normally reserved for racing cars. Its ingenious shape accelerates the air drawn in here for the two cylinder banks of the V12 TDI engine.

A “showroom” for the engine

The V12 TDI is displayed as the beating heart of this sports car, like a work of art inside a large showcase. Its look, underscored by the air deflectors located beneath the restyled rear glass lid, differs clearly from its production counterpart. The engine can even be seen after dark, when white light-emitting diodes illuminate the engine compartment – as on the production R8 version.

Innovative LED technology

The LED taillights of the Audi R8 V12 TDI concept have a three-dimensional look that can’t be missed. But the absolute highlight is the all-LED headlights of the study vehicle. With their lenses and reflectors, not only do these innovative light sources have a ground-breaking appearance, they also have an enormous functional advantage: LED light, with its color temperature of 6,000 Kelvin, resembles daylight much more closely than xenon or even halogen light.

Interior: Ergonomic and elegant

The interior’s design is as sporty and exclusive as the exterior: the characteristic element here is the monoposto – an expansive arc running around the steering wheel and instruments, connecting the driver to the car. The interior consequently picks up on the dynamism of the R8 V12 TDI concept and gives it tactile expression in a form that is accessible the moment you climb in.

The focal point of the car’s controls

The three-spoke sport steering wheel of course remains the focal point of the car’s controls. With a diameter of 365 mm, it is both sportily compact and ergonomic in shape. The steering wheel rim has a flat lower edge. The start/stop button for the engine and the Drive Select switch with the Dynamic/ Sport/Race settings are arranged on the steering wheel. The latter controls the engine and transmission electronics as well as the magnetic ride dampeners in each of three different modes.

Top sports in Race Mode

In Race mode, the instrument lighting changes from white to red. The navigation system shows a combined display with lap timer and navigation information for the racetrack being driven. Or supplementary information such as centrifugal force and boost pressure can be called up.

Exceptional everyday practicality

The R8’s exceptional everyday practicality for a sports car is maintained in the study vehicle’s spaciousness, even though the longer engine takes up more room. The two occupants have the generous wheelbase of 2.65 meters (8.69 ft.) to thank for the interior comfort. This means the driver and passenger will always be able to find their perfect seated position, whatever their build.

A decidedly sporty feel

Compared with the production version, the R8 V12 TDI concept’s interior has much larger aluminum applications, especially around the center console. The many carbon fiber elements give the interior a decidedly sporty feel.

Drive Train: Superb performance

The roadgoing version of the new V12 TDI is built at the Györ plant, in Hungary. And the R8 V12 TDI still has a massive 500 hp on tap. The 83.0 mm bore and 91.4 mm stroke produce a total displacement of 5,934 cc. At only 684 mm long, this large diesel engine is very compact and just 166 mm longer than the V8 TDI. This compact length is key to accommodating the V12 in the mid-engined Audi R8.

Innovative injection technology

The two new dual-piston high-pressure pumps build up a pressure of up to 2,000 bar in the rails. The high pressure distributes the mixture optimally throughout the combustion chamber. The result is that the ignition process is faster, more homogeneous and more acoustically refined. The more efficient combustion process also increases power output, cuts consumption and reduces pollutant emissions.

Two turbochargers

The two turbochargers are located on the outside of the engine’s V and generate up to 2.6 bar of boost pressure. They play a crucial role in producing the huge torque of 1,000 Nm that the V12 TDI maintains from 1,750 rpm to 3,000 rpm. In developing 368 kW (500 hp), the diesel achieves a specific output of 62.0 kW (84.3 hp) per liter displacement.

Clean top athlete

The Audi R8 V12 TDI concept already fulfills the Euro 6 emissions standard. The heart of the system is a special catalytic converter downstream of the oxidizing catalyst and the particulate filter. The second component in the system is an additional tank containing an aqueous urea solution. Small quantities of the solution, known as “AdBlue,” are injected into the exhaust system. The hot exhaust gases break the solution down to form ammonia that splits the nitric oxides into nitrogen and water.
