industry show in April 2019. The futuristic design concept reflects the sleek lines of the Chinese dragon, and the company plans to feature more Chinese cultural symbols in future models. At the present time, the Chinese corporation has over 190,000 individuals working for it all over the globe and generates approximately $9.1 billion in revenue. The production of mobile phone batteries was where the firm got its start, but they swiftly expanded their offerings to include original equipment manufacturer (OEM) phones for the information technology sector. Technologies DM (dual mode) hybrid The BYD DM hybrid technology was first introduced in the late 2000s, on vehicles such as the BYD F3DM and BYD M3 DM. It consisted of a conventional ICE engine and transmission as well as an electric motor and batteries. It has since been replaced by DM-i and DM-p technology. DM-i / DM-p In 2020, BYD released DM-i and DM-p to replace DM technology, DM-i for front-wheel drive efficiency-oriented models and DM-p for all-wheel drive performance-oriented models. It is a series-parallel plug-in hybrid technology with a dedicated hybrid transmission (DHT). It consists of a high-efficiency ICE engine (Xiaoyun) (which can power an electrical generator) and a main electric motor (which can be powered by both batteries and an electrical generator). The Xiaoyun engine uses the Atkinson cycle, has an ultra-high compression ratio (CR) of 15.5, and has a Brake Thermal Efficiency (BTE) of 43%, the highest in the world for a production gasoline engine. Depending on the scenario, the hybrid drivetrain will use different components to provide driving power, including battery-only mode, battery + electrical generator mode, engine only mode (only available at high speeds due to lack of transmission), and battery + engine mode. The engine will also provide charge to the batteries via the generator when conditions permit. The design allows the engine RPM to always remain within its high efficiency zone. DM-i is currently available with three power levels, codenamed EHS132, EHS145, and EHS160, using 1.5L, 1.5L or 1.5T, 1.5T Xiaoyun engines respectively. e-Platform 3.0 The e-Platform 3.0 is a new modular car platform unveiled in 2021 said to be "the cradle for the next generation of EVs". It is a platform specialised for only battery electric vehicles (BEVs), unlike previous vehicle platforms which had to make design compromises for the hybrid vehicle drivetrains of its DM ("dual mode", i.e. plug-in hybrid) variants. Standard improvements include
