BP fuel test vehicle
 

Audi 4.2 V8 fuel test vehicle for BP. Each bank of 4 cylinders is run on different fuel and then each side can be compared for different deposits.

From google translate (as I couldn't find an english source)

First open road and then roll in banks has been carried out a long reliability test with an Audi A8 4.2. The preparation of this vehicle has been to completely separate its two banks of the mighty eight-cylinder V

Since deposits independent injection and exhaust gas, the left and right benches have worked with two different types of gasoline. On one side is always injected BP Ultimate. The other four cylinders have worked with a more conventional gasoline. The final results are visible through two small surgical cameras coupled to intake manifold just above the zone valves. The test ended with a clear difference between the deposits formed in either zone.

Very interesting.

Imagine how cool it would be having them cameras permanently installed in your car and with a flick of a button just switch the image to the MMI screen, very cool :D

How badly do you want it Marcin, it's totally doable.
