By the way talking about the Motronic is like saying its got an Intel Chip in it, thats a third party platform that many use and program themselves.
Mick, you don't have a clue about engine software programming, do you?
I try to explain it in a very simple way: there are certain parameters in the engine software which are each adapted to certain functions like ignition, boost pressure, fuel pressure, etc. Two different engines don't have one single parameter in common, this wouldn't make sense. It is like running Windows on a Linux machine, even more difficult. It doesn't have anything to do with the processor. You can run various software versions on the same processor platform but you don't really want to tell me that Linux, Windows and BeOS have really something in common?
By "accident" (
), the RS6 engine software has a lot of parameters in common with the Cayenne Turbo engine software. Now this is like discovering Windows source code in a Linux distribution.
Impossible. And furthermore, the software has a certain part number to know which version has been programmed. Now what a co-incidence that we just discovered that Linux has a Windows XP build in it.
Of course it doesn't say anything if the software in the Cayenne Turbo motronic has an Audi part number embedded in it, they just forgot to remove it, right?
Oh, but the ME 7.1.1 is made by Bosch, so what does the Audi part number do in the Cayenne Turbo motronic. And furthermore, the RS6 uses a ME 7.1.1 too, another co-incidence, right? It is funny that neither the 996 C2/C4/etc. nor the GT3/G2/996 Turbo or even the CGT use a ME 7.1.1.
But what co-incidence...the Touareg V8 uses a ME 7.1.1.
C'mon Mick, I really don't understand why you are that surprised? Porsche always had close ties to VW and Audi, this is nothing new. I'm only a little bit surprised to learn that the Cayenne V8 engine might actually be an Audi development and not a 100% Porsche development, nothing more and nothing less. I'll still love my Cayenne Turbo but a little disappointment should be allowed.
I really don't understand why a discussion about the provenience of the Cayenne V8 engine shouldn't be allowed.
If it is a 100% full Porsche development, Porsche has nothing to fear about. And if not, well, they should clarify it.
BTW: if it wasn't about the press, did you see anywhere a claim from Porsche that the Cayenne V6 engine is an overworked VW engine?
Here is Porsche's original statement about the V6 engine:
Introducing the new Cayenne, Porsche is rounding off its range of Sports Activity Vehicles through the addition of this new, "basic" model. Powered by a sporting V6, the latest Sports Utility in the range offers the same supreme standard of driving dynamics, safety and off-road qualities for which the third Porsche is already acknowledged the world over.
In its engine output and performance, the Porsche Cayenne, just like its sister models, offers a supreme standard: Maximum output of the six-cylinder power unit at 6000 rpm is 184 kW (250 bhp), maximum torque is 310 Newton-metres (228 lb-ft) from 2500 - 5.500 rpm. Indeed, the torque curve alone is an outstanding symbol of muscular performance, exceeding the mark of 300 Newton-metres (221 lb-ft) just above 2000 rpm and remaining above this limit all the way to 5500 rpm. The performance this means in practice speaks for itself, the Porsche Cayenne accelerating from 0 - 100 km/h in 9.1 seconds, then continuing all the way to its top speed of 214 km/h or 133 mph.
This superior power and performance rests on a clear and convincing technical foundation. The new six-cylinder is a 24-valve power unit with cylinders at an angle of 150 and two overhead camshafts adjusted both on the intake and outlet sides in a continuous, infinite process using vane-cell adjusters. This engine concept makes the Cayenne a very fuel-efficient vehicle, returning superior fuel economy of less than 12 litres/100 km or more than 23.5 mpg Imp on the road. According to the EU standard, the Cayenne consumes 10.6 litres of fuel for 100 kilometres outside of town (26.6. mpg Imp), composite fuel consumption under the EU standard also including urban motoring amounting to 13.2 litres/100 km (21.4 mpgImp).
