What is the difference between DM and DMI?
3 Answers
The differences between DM and DMI are: 1. Different functions: The DM engine can charge the battery and provide power output; the DMI engine is a pure generator and cannot provide power output. The length, width, and height of both DM and DMI are: 4870mm, 1950mm, 1727mm, with a wheelbase of 2820mm, maximum power of 145kw, maximum torque of 316nm, and a fuel tank capacity of 53l. Both DM and DMI have front-wheel drive, with front suspension type being MacPherson independent suspension and rear suspension type being multi-link independent suspension.
I've driven both DM and DMI versions of cars, and the difference is quite noticeable. The DM system feels like an athlete, with an exhilarating push-back sensation during acceleration, especially when overtaking on highways. However, the downside is obvious—when the battery is low, fuel consumption skyrockets, almost like drinking oil. On the other hand, DMI is more like a meticulous housekeeper. It prioritizes electric drive, and the engine mostly operates within an efficient range, so fuel consumption remains stable regardless of the battery level. I drive the Song PLUS DMI daily for commuting, and even when the battery is depleted, the fuel consumption is only around 5 liters, cutting my commuting costs by half compared to my colleagues' fuel-powered cars. Another advantage of DMI is its exceptionally smooth driving experience, with almost no jerking. If I were to recommend, for those seeking driving excitement, go for DM; for those prioritizing economy and practicality, DMI is the way to go.
As an average car owner, what matters most are the cost of ownership and hassle-free experience. DM vehicles are indeed fuel-efficient when fully charged. Once I drove the Tang DM for 50 kilometers purely on electric power, spending only a few yuan on electricity. However, the issue is that fuel consumption skyrockets when the battery is depleted, reaching up to 9 liters per 100km on highways, essentially turning into a gas guzzler. The DMI system is much smarter, employing a dual-motor design where the engine primarily operates at optimal RPM to generate electricity, while the drive wheels are controlled by the electric motor. Recently, driving the Qin PLUS DMI to take my kids to school, even when forgetting to charge, it maintained just over 4 liters per 100km. With 200 yuan worth of fuel, it can cover nearly 1,000 kilometers. In terms of maintenance, the DMI's mechanical structure is simpler than DM's, with my first service costing just over 300 yuan. If you ask me, when buying a hybrid now, you really should opt for newer systems like DMI.
