Oaris will be a non-articulated electric multiple unit with distributed traction, enabling 4-car, 6-car and 8-car configurations. Each car will have one powered bogie, with electric motors on both wheelsets, and one unpowered bogie. Power equipment will be designed to enable adaptation to all four of the main overhead electrification systems in use across Europe. For the train, running gear with 1,435 mm (4 ft 8 1⁄2 in) (standard gauge), 1,668 mm (5 ft 5 21⁄32 in) (Iberian gauge) and variable gauge options is developed.
Oaris bodyshells will be manufactured from aluminium. The driving end cars will be 26,780 mm (87 ft 10 in) long, middle cars 24,780 mm (81 ft 4 in) long, an 8-car set will be 202.24 m (663 ft 6 in) long.
The train will be fitted with 660 kW (890 hp) motors, giving a total power of 5,280 kW (7,080 hp) in the 4-car, 7,920 kW (10,620 hp) in the 6-car, and 10,560 kW (14,160 hp) in the 8-car configuration. Design speed is 350 km/h (220 mph), planned top speed in service is 320 km/h (200 mph).
- May 2010. After fours years of development in a project supported by CDTI, CAF announced the Oaris platform with the unveiling of a full-scale mock-up in May 2010 in the International Rail Forum 2010 at Valencia.
- September 2010. A prototype starts to be assembled by CAF. It has 4 cars and is designed for 216 seats. Renfe has reserved the class 105 for the prototype.
- January 14, 2011. CAF announces that the prototype is finished and will undergo dynamic tests in early 2011.
- December 2011. Four-car prototype undergoes trials at up to 352 km/h on the Madrid to Sevilla route.
- Spring 2013. Prototype gets homologation by Brazilian Railindustry Association, which will allow CAF to offer trains for the proposed high-speed rail connection between Rio de Janeiro and São Paulo.
- 2013. Test runs for homologation in Spain. In October 2013 company sources said the approval process of Oaris is in the final stages and within months is ready for operation.
- March 2015: The Norwegian airport train operator Flytoget ordrered eight 4-car trainsets (maximum speed 250 km/h) to supply their 16 trains fleet on their Drammen-Oslo-Gardermoen Airport service. They will be known as Class 78.
