The August 20-23 event represents Paddon and Kennard's third run at Rally Germany but the first time they have piloted a WRC car in what is widely recognised as the most difficult tarmac event of the WRC calendar.
''We have done maybe 30% of the route before which will help, but never in a WRC car,'' Paddon said from his European base in Frankfurt.
''The speed difference between WRC2 and WRC cars is much greater on tarmac and this will be the biggest thing to adapt to from our previous experience of this event.''
The German rally provides drivers with a series of technical challenges, including twisty Mosel vineyard roads and Baumholder military tracks for which accurate pace notes are essential - particularly to avoid the huge car-breaking kerbstones known as hinkelstein.
The weather is typically unpredictable, making tyre choice an important factor and placing a premium on up-to-date information from the team's weather crew.
Paddon said the event required constant adjusting throughout the 21 stages.
''It's almost like three rallies in one. You have the rough, slippery military range stages, the bumpy, tight technical vineyard stages, and then the sections that are wider, smoother and on public roads.''
Driving the No 20 Hyundai i20 WRC in the Hyundai Mobis World Rally Team colours, Paddon starts this event with the same specification car as Hyundai Motorsport team-mates Thierry Neuville (No 7 Hyundai i20 WRC) and Dani Sordo (No 8 Hyundai i20 WRC), who secured a one-two finish at this event last year.
The 2015 event marks Hyundai Motorsport's first tarmac event with four cars, as Dutchman Kevin Abbring joins the Hyundai Mobis team for the second time this season, driving the No 10 car.
For Paddon it means extra pressure.
''This event will be more difficult for us, especially with what I would describe as three team-mates who are tarmac specialists. This is a surface we don't have a lot of experience on,'' he said.
''So, yes, we will have our work cut out for us, but I see this as a positive and I am sure we can learn a lot from our team-mates throughout the rally. The biggest thing, of course, is for us to learn and get to the finish. If we can try and be in the top 10, great.''
As part of his pre-event preparation, Paddon headed to the United Kingdom to spend a day with racecraft coach, expat Kiwi Rob Wilson.
''It was good to spend some time with Rob, whom I also did some work with a few years ago. Tarmac rallying requires a different mindset and understanding of weight transfer and smoothness.
"Rob really helped to knuckle this into my brain and practise it. It's not something I will perfect overnight, but gives me plenty to think about and consciously work on,'' Paddon said.
He and Kennard are one of 16 WRC crews for the German rally facing Friday's eight stages, mostly close to the Luxembourg and Belgian borders.
Saturday's nine stages mix country roads, vineyard tracks and the daunting double run through the Panzerplatte military area before Sunday's final four stages in the Mosel wine area.
