Byd DM-i, DM-p, EV difference

In the planning of BYD powertrain, DM (Dual Mode) plug-in hybrid is divided into i and p two branches, the former pays attention to fuel saving, and will reduce the entry price, the latter focuses on performance, the price is relatively higher. EV (Electric Vehicle) stands for pure electric drive, which belongs to the category of new energy vehicles.

DM-i is DualMode-intelligent, which means intelligent and efficient dual-mode system. It is a high-power motor drive and large-capacity power battery power supply, supplemented by the engine of the electric hybrid architecture, the system work efficiency is extremely high, the main fuel economy. In the DM-i, the traditional gasoline engine is an important part of the overall efficiency. It matches the BYD Snapcloud series engine, the highest thermal efficiency of up to 43%, in the current production engine thermal efficiency it ranks among the best.

DM-p means DualMode-powerful, which means a dual-mode system with strong power performance. It is mainly divided into two architectures, one is "three-engine four-drive" (that is, P0+P3+P4), and the other is "two-engine four-drive" (that is, P0+P4), focusing on acceleration performance and handling stability performance.

Take Tang DM-p as an example, the comprehensive power up to 452kW (615hp), 0-100km/h acceleration time only 4.3 seconds, equipped with a super intelligent electric four-wheel drive system through the vehicle torque control and distribution strategy, at different speeds, different loads, according to different acceleration curve to distribute appropriate torque to the front and rear drive assembly. It can effectively ensure a stable body attitude under different road conditions.
