Proton made its presence felt for the very first time in Japan when renowned Japanese automotive parts manufacturer Carrosser Co., Ltd. (CUSCO) officially unveiled at the Tokyo Auto Salon, a specially-developed Satria Neo rally car that will be sold in Japan.
In January 2011, Proton announced that Japanese auto parts company CUSCO would be buying standard road-going Satria Neo body shells to engineer and homologate according to FIA Group N regulation competition use.

The Group N Proton Satria Neo rally cars will be based on stock standard road-registered 1600cc showroom models acquired by CUSCO, homologated according to FIA regulations for competition use, and retrofitted with CUSCO-developed aftermarket performance and race components.
With the Satria Neo, CUSCO is essentially Proton's customer – they buy the body shells, equip them with CUSCO-developed race components, and then sell the completed Group N rally-going Neos to customers who will compete in Junior Rally Championships in Japan and Asia Pacific.

Veteran Malaysian rally driver, Karamjit Singh piloted a CUSCO-tuned Proton Satria Neo 2WD in which he crossed the line to finish first in the overall 2011 APRC 2WD category on May 2011 Rally of Queensland as well as first in the N2 category.

Three Satria Neos were fielded in the 2011 Japan Rally Championship in JN-3, one unit for the CUSCO Team and two for the CUSCO Junior Rally Team respectively.
The latter finished with a class win in Rally Hokkaido 2011.
In the 2012 season, only the Junior Rally Team drove the Satria Neos, whereas the CUSCO Team had replaced their unit with a Toyota 86.
