Design and performance


The first generation Promessa in R4: Ridge Racer Type 4

In it's first appearance in Ridge Racer Type 4, the Promessa is a starting car when players choose Assoluto as their manufacturer of choice. Here, it resembles the second-generation Toyota MR2 (especially the rear end), with a racing air snorkel in the engine bay. The car is also one of the preset cars, using the alias of Preset D1; this version is based on the Pac Racing Club specification, like all other Preset cars.

The version in Ridge Racer for Vita features a high resemblance to the W Motors Lykan Hypersport in terms of external design, and a few details of the new Honda NSX, especially in the mechanical and backstory department: the car was stated to be launched in an car show in the United States in June 2011 (the first NSX concept was launched in January 2012 in North American International Auto Show) and includes a Motor Assist Hybrid system. The car retains the trademark rear snorkel. However, the new Promessa uses a 2400cc flat-6 engine (the same type that Lykan used, although the Lykan had 3700cc displacement), in contrast to NSX's 3500cc V6. The racing version of the car is known as Evo3 in the car's description, and is stated to be developed six months after the production model. The Japan/Asia-only IDOLM@STER EX Color for this car (downloaded separately) features Yayoi.
