Exterior fata. Nota 4. E incredibil cum un element prost plasat si urit, strica o intreaga masina.

Era si cazul ca A8 sa primeasca o motorizare de top avand in vedere ca "masina poprului" (big passat) deja dispune de acest motor de multa vreme.

To introduce a super-luxury sedan into any market requires a great deal of thought and organization. It comes to us as no surprise that when Audi brought the A8 to North America, it did so initially with the 'L' long wheelbase version of the A8. Worldwide, the same could be said with the 6.0 liter W12 version - up until currently, it was only available with a stretched wheelbase. However, Audi have decided upon releasing a regular wheelbase version of the A8 6.0 Quattro. Although it bears the same odd face as the A8 6.0L Quattro, its wheelbase is identical to the normal car - some 13 cm shorter than the long variant. Total wheelbase length is just shy of three meters (2944 mm).



Regular-size A8 receives the big W12 engine making this a smaller-sized vehicle to crown Audi's lineup.

Though it may look the same as the larger A8, there are quite a few changes between the normal and the W12 version. First off is the motor, whose history can be traced through the first generation A8. Here, it produces more power - a total of 450 hp. Although it isn't enough to outpace the twin-turbocharged Mercedes-Benz S600, it's enough to make the A8 quite brisk. The regular wheelbased A8 features the same six-speed ZF automatic gearbox as the long version, but its first five ratios have been shortened to provide quicker acceleration. It works, taking just 5.1 seconds to hit 100 km/h, and 16.9 seconds to hit 200 km/h. This can be compared to the long wheelbase which takes 5.3 and 17.4, respectively.



Despite being smaller and lighter, the A8 6.0 Quattro consumes more fuel than the long wheelbase version.

Though the A8 6.0 Quattro with the regular wheelbase is lighter by roughly 35 kilograms, we figure that it should not only out-accelerate the long version, but beat it out on fuel economy. While it's true that it completes the first task, it lags (for some odd reason) in fuel consumption. Under what circumstances Audi tested the A8 6.0 we're not too sure of, but it takes 14.8 l/100 km of the liquid gold otherwise known as premium unleaded. This is 1.0 l/100 km more than the heavier long wheelbase version! The A8 6.0 Quattro on the regular platform will be available in the second quarter of 2004 with the price tag of 106,900 ($180,000 CAD, $130,000 USD)

2004 Audi A8 3.0 TDI Quattro - Economic Extravagance

Ingolstadt, February 26, 2004 - The new Audi A8 3.0 TDI quattro with piezo common rail system Long-distance specialist with sprinter qualities
The Audi A8 can now be ordered with a completely new six-cylinder TDI engine. Costing � 60,500, the A8 3.0 TDI quattro represents the addition of a further sporty version with the characteristics of a long-distance luxury saloon to the A8 range.

The six-cylinder engine in the A8 3.0 TDI quattro develops 171 kW (233 bhp) at 4,000 rpm and summons up an impressive 450 Newton-metres of torque between 1,400 and 3,250 rpm. The lightweight luxury saloon with aluminium body is thus capable of sprinting from 0 to 100 km/h in just 7.8 seconds � a world best for a V6 diesel saloon � and goes on to a top speed of 243 km/h.

The 3.0 TDI is the first production diesel model in the world to have the pioneering common rail fuel injection concept with piezo inline injectors. This permits up to five injection processes per operating stroke and an injection pressure of 1,600 bar.

Piezo technology makes it possible to inject much smaller, more precisely metered amounts of fuel. Thanks to the higher speed of the injector needle, the system moreover responds twice as fast as other injectors. This effect is particularly important for brief intervals between the offset multiple injection processes, of which there may be up to five. The fuel is injected into the combustion chamber via 7-hole nozzles. They, too, play a major part in making the combustion process ultra-efficient and improving the quality of emissions, by distributing the fuel homogeneously throughout the combustion chamber.

The V6 TDI belongs to Audi's new range of V?engines and has a chain drive for camshafts and oil pump. The cylinder spacing in the new engine block is now 90 millimetres. The engine consequently measures a compact 444 millimetres in length. The engine block is made from vermicular graphite cast iron. This is one of the vital clues to the engine's low overall weight of just 220 kilograms � the 3.0 TDI is one of the lightest diesel V6s around. This benefits the power-to-weight ratio and the weight distribution in equal measure � two characteristics that are of central importance for the driving dynamics of the new A8 3.0 TDI quattro.

Further distinguishing features of the engine include four-valve technology with low-friction roller cam followers, turbocharging with two charged air coolers, and electric actuation of the variable turbine geometry, with faster and more precise adjustment of the vanes even at intermediate stages. Particularly at low engine speeds, this builds up the boost pressure faster and thus achieves significantly better responsiveness.

There are likewise continuously variable swirl flaps integrated into the intake tract. They can be used to adjust the air movement according to the prevailing engine speed and load.

All these measures result not merely in high performance potential and an enormous torque plateau, but also in reduced fuel consumption and outstanding acoustic behaviour. Particularly in this discipline, the new engine now unquestionably serves as the benchmark in its class.

And even with 6-speed tiptronic and permanent four-wheel drive, the A8 3.0 TDI quattro � the very first diesel in the luxury class to have controlled, cooled exhaust gas recirculation � undercuts the emission limits of the tough EU4 standard that will apply from 2006. It thus complies with the requirements for tax exemption for a limited period in Germany.

One feature of the new engine that is undoubtedly as welcome as its efficiency at reducing emissions is its impressive fuel economy: the tank dispenses just 8.4 litres of diesel over 100 kilometres (overall fuel consumption).

It therefore comes as no surprise to learn that the new A8 3.0 TDI quattro has an operating range of over 1,000 kilometres on a single tank of fuel. This is a figure that singles out the sporty saloon with TDI engine as the perfect long-distance vehicle

The first proud owners of the new Audi A3 3.0 TDI quattro will be taking receipt of their cars in April.

Ma uit la masina aia roz si nu imi dau seama ce a vrut ala sa faca. Probabil sa iasa mai urita ca 7xx insa tot nu a reusit.

Pacat de motorul ala V6 TDi care e plin de tehnologie insa nu convinge deloc in "real world", chiar pierde la un motor "antic" de pe acum L6 3,2 204cp Mercedes.

Date declarate, eu zic sa analizezi ultimul test 320, 530d si A6 V6 TDI si o sa fii dezamagit. Eu am fost.http://www.garajul.ro/forum/public/style_emoticons/default/thumb.gif
