Subaru test tracks - Bifuka proving ground (speed circuit, toge, etc...) 1.1

G'day, mates.

Latly i was working on one track, located in the north of Japan. Track, that far from being famous. This tracks is also far from motor-racing. BUT....it's kind of unique. Big test park of Subaru company, made for different types of road car testings.

And being Subaru Legacy owner, i would like to bring more Subaru stuff to virtual world.

What i did is took the track is remade this Proving ground to race track! (some imagination)


This is a Subaru test course スバル美深試験場 (Subaru Research and Experiment Center Bifuka Proving Ground) in Niupu, Bifuka-cho, Nakagawa-gun, Hokkaido. The Bifuka Proving Ground was opened in 1995. Until the test site was opened in 1995, we had repeated driving tests on ordinary roads in this area. Established in 1995 as a research and development base for winter snow tests, we have been conducting research and development mainly to build cars that can be driven safely even in cold regions.

In addition to various test roads and handling roads in the total site area of

361 hectares, a high-speed circuit was added in 2003, and various tests are conducted throughout the year as a test course that looks like an actual public road.



Track made from scratch, using RTB, google maps, and some Kunos objects.


#1 High-speed circuit - total length 4.2km. Can be extended in future updates with extra loop already presented on 3D map.


Really interesting high speed road with old chool racing turns. The track is fun for road cars and classic retro race cars. Modern GT3 is not best choise for here, my oppinion.

Release version Support race (not weekend) with 27 Ai and good replay cam.

Onboard video on Youtube + Porsche 804 onboard video from the track. It's fun!

#2 Mountaing toge course is 2.0 km. Short, but very very tricky road.

Probably this test course is usnig for suspension tests or even for mud running. But i saw it has potential to be high-level toge circuit with up and down hill combined. No rail guards, so should be carefull here =)

Release version Support race (not weekend) with 1 Ai and good replay cam.
