"We had a two-day test and, although it was cut short and I'm sorry for my team-mates who were unable to continue, the car felt fantastic," said the undaunted Frenchman.
"The Finns certainly know how to deliver a good rally and these gravel roads are tailor-made for rallying.
"It's fast - really fast - and the big jumps and high grip levels offer an incredible sense of speed that every driver looks forward to. At that pace, you're fighting for tenths of a second and I'm expecting a very close battle."
Neuville is on a run of six consecutive podiums in his Hyundai i20 Coupe, including victory in Poland earlier this month which ignited the head-to-head duel.
"We hope it can be a real catalyst for further success moving towards the end of the season," said the Belgian, who won a warm-up rally in Finland two weeks ago.
"The car is looking very strong and with two wins on gravel already this season it has shown how competitive we can be. We're confident we can continue to challenge for the championship.
"We know Finland can be a tricky event because the margin of error is minimal due to the high speeds and complexities of the roads," he added.
Kiwi Hayden Paddon will start seventh on the road and is hoping for a big result at an event he enjoys.
The four-day event starts in Jyväskylå on Thursday evening (local time). Drivers face 25 speed tests covering 314.20km among the forest and lakes before Sunday afternoon's finish.
