The meaning of «daihatsu new global architecture»

The Daihatsu New Global Architecture (abbreviated as DNGA) is a modular unibody automobile platform that underpin various Daihatsu vehicles and its rebadged versions supplied for Toyota, Subaru, and Perodua. Introduced in 2019, it is aimed for vehicles built for the Japanese market and overseas emerging markets.[1] The DNGA is claimed to be developed with electrification, autonomous driving and connectivity in mind, which the company refers as "CASE" (Connected, Automated Driving, Sharing, Electrification).[2][3] Daihatsu has planned to introduce the platform to 21 models and 15 body types with a targeted annual production of 2.5 million vehicles to be sold in 90 countries by 2025.[1] Despite the similar name, it is not related to the Toyota New Global Architecture.[4]

The platform was announced in June 2019 through the introduction of the fourth-generation Tanto.[5] Prior to the introduction of the Tanto, the second-generation Mira e:S and the Mira Tocot released in 2017 was claimed to be based on the DNGA,[6][7] however later in 2019 it was revealed that both cars are not built on the DNGA.[8] Instead, it uses an older transitional platform which is the origin of the DNGA platform before it was improved further.[9]

Most components have been newly developed for the platform, and all components such as the suspension and its mounting points, underbody, engine, transmission, and seating position have been revamped for an optimal and standardized component placement to achieve the desired performance and quality without increasing costs.[10] The structure of chassis parts has been streamlined, and the number of parts has been reduced to reduce weight.[11]

The platform allows parts sharing rate to exceed 75 percent for kei car models and 80 percent for A-segment and B-segment models.[4] As the result, development of new models to its introduction is 1.5 times faster. Since the manufacturing plants are able to utilize a common assembly line for DNGA models, the capital investment of introducing a new product is also reduced by 30 percent. After the deployment of DNGA, the number of platforms produced by Daihatsu would be reduced from the 7 types to 4 types.[4]

Despite having a name similarity with the parent company's Toyota New Global Architecture, there are no mentions of the platform being related with the TNGA in Daihatsu publications and literatures. Daihatsu executives stated the company did not pursue significant commonality with Toyota platforms.[4]

The chassis, which is the main component of the platform is grouped into three types, which are the kei car segment, A-segment, and future B-segment products for emerging markets.[1]
