Audi Q7 V12 TDI: the day that Audi has launched an SUV diesel 12-cylinder engine and technology from Le Mans

, Today, a diesel engine V12 you may seem like a lot, but that impression is not very different from the one we already had in 2007, when Audi presented us with a project as crazy as the Audi Q7 V12 TDI with 500 HP of power and 1,000 Nm of maximum torque. It is said fast. To understand why, in Ingolstadt had the audacity to launch an Audi Q7 with a diesel engine of twelve cylinders, to make matters worse he had been created to the extent of the u.s. market, we position ourselves very well in the context of those years. This story comes to story in a time when we have also attended the presentation of a Q7 diesel and very sporty special, the Audi SQ7 TDI 2016. But why launched Audi a diesel twelve-cylinder technology and a champion in the 24 Hours of Le Mans?

The two reasons why Audi created the Q7 V12 TDI are Le Mans and the united States, but neither engine was the same as that used in Le Mans, or else would market in the united States.

Audi had made champion diesel in resistance, and not in a race either, but in the most important of all, in the 24 Hours of Le Mans. Audi had scored a major victory in a career that their diesel have dominated with authority from the Audi R10 TDI did the same in 2006. Audi also had a strong commitment by the diesel in the united States, a fact we already know in these days, in the case of the fraud of the TDI is still present.

18 years after the birth of the TDI of Audi, in Ingolstadt had had the bright idea – or not – to launch an SUV with an engine of twelve cylinders, to make matters worse he had some connection with the sport of racing, the Audi R10 TDI.

This engine was born by joining two blocks of six cylinders by bringing together the two engines, 3.0 TDI V6.

But in reality the twelve-cylinder engine used by the Audi Q7 V12 TDI would be a capacity even higher than that of the Audi R10 TDI, which cubicaba 5.5 litres. Audi decided to join two banks of six cylinders in a v, of his famous 3.0 TDI, with a diameter of 83.0 millimeters and a stroke of 91.4 millimeters. And managed to do so in a way that its size, thanks to the distribution in the vee of the cylinders, it would be sufficiently compact as to enter in the vain of the engine of the Audi Q7. Audi also had in mind certain peculiarities, like the fact of placing the cylinders in a v-narrow, 60°, instead of 90 degrees regular in your V6 TDI.

As it could not be less, this V12 TDI 6.0-liter was supercharged, double, with a turbocharger for each bank of cylinders. Remember that this engine accelerated from 0 to 100 km/h in 5.5 seconds, delivering 1,000 Nm between 1,750 rpm and 3,000 rpm and a maximum power of 500 HP.

An amazing figure, or even come to the brand spanking new Audi SQ7 TDI 435 HP modern, which remains at a respectable 900 Nm between 1,000 and 3.250 rpm. Recall that the latter has a V8 engine TDI, two turbos, and an electric compressor. The Audi SQ7 TDI is, without a doubt, the spiritual heir of the Audi Q7 V12 TDI of yesteryear. And is that even with four cylinders less, we are in a block to really innovative, will be the first time you apply the technology of the electric compressors in a street car and series.

why is an Audi diesel, and with twelve cylinders for the united States?

Audi, and the Volkswagen Group in general, had wagered with a lot of force for the introduction of the diesel in the united States. So much so that, as you already know, would be incurred in a fraud to homologate the diesel in compliance with the strict regulations of NOx emissions present the other side of the Atlantic. In any case, all that would happen by the conviction that, sooner or later, the us customer would end up surrendering before the performance, the low consumption, and the autonomy of the diesel. And what better way to offer benefits scandal that a diesel below the 2,000 laps already delivered 1,000 Nm?

This engine was equipped with a gas treatment system based on AdBlue, specifically the system Bluetec Daimler, who in his day, the Volkswagen Group took the opportunity to get their diesel to comply with the us rules.

the most curious of the matter is that this diesel twelve-cylinder, which initially Audi so much interest had at launch in the united States, I would never make the american licensees. Audi ruled out the idea, and did not approve their car under the low emissions standards of the united States, according to said, considering that it was not feasible, in both the sales forecast was too low. However, it did bet the engine 3.0 TDI V6, which not only was present in the Audi Q7, but also in the rest of the range Audi sold in north America.

In Europe, on the other hand, would be sold. And the Audi Q7 V12 TDI would, up to our days, of the privilege of having been the only engine of twelve cylinders in a v that we have ever seen in a diesel street.

In his day, Jeremy Clarkson would describe this engine as a “stupid”, “brilliant stupidity.” But I’ll stick with the phrase of one of the members of Piston Heads that was referred to this Audi Q7 V12 TDI with the best phrase that I’ve heard to define it: “it Is obscene. But I like it.”
