For most family consumers, the priority of buying a car is naturally to have a large space, strong power and low fuel consumption. In the hybrid family car market of 100,000-150,000 yuan, BYD Qin PLUS DM-i is a model that has attracted much attention, which is well suited to the needs of family consumers, and sales have been rising since its listing. The Corolla Twin Engine is one of the representative models of the joint venture compact economy car, and the strength should not be underestimated. Who is better to choose between the two models? Let's take a look.
First of all, let's talk about the hybrid technology concept of BYD and Toyota, there is no doubt that both models are equipped with the current more advanced hybrid technology.
The DM-i super hybrid system equipped with QinPLUS DM-i consists of a 1.5L high-efficiency engine for Xiaoyun-plug hybrid, an EHS electric hybrid system and a DM-i super hybrid special power blade battery.
The core technical point of the DM-i super hybrid system is the drive mode with electricity as the main and the engine as the supplement. The system provides EV pure electricity, HEV series, HEV parallel and engine direct drive four power modes, DM-i system will intelligently switch power modes according to the user's use scenarios, so as to bring economical fuel consumption performance.
However, in either mode, the system is mainly driven by the motor. Most of the engine conditions will focus on the efficient working area of thermal efficiency of more than 40%, only to drive the generator to generate electricity; the engine direct drive mode will only work in the most economical high-speed endurance road conditions, which can bring almost an electric vehicle-like driving experience.
Toyota THS hybrid system has been widely known, mature and advanced technology, has an excellent market reputation, and has maintained a leading position in the hybrid vehicle market for more than two decades.
The THS II hybrid system on the Corolla Dual Engine uses an upgraded version of the 1.8L Atkinson cycle engine for more stability and efficiency.
The core of this hybrid system is to connect the two motors and engines well through the planetary gear structure, and make appropriate adjustments according to different working conditions, so that the engine can be maintained in the high efficiency working range for a long time to achieve the purpose of fuel saving.
The two hybrid systems work differently, but both are fuel-efficient at their core. Qin PLUS DM-i fuel consumption can be as low as 3.8L/100km under power loss, and the fuel consumption of Corolla dual engine is also as low as 4.0L/100km, and the fuel consumption performance is excellent enough, and the cost of the later car is low.
In contrast, the DM-i super hybrid system is plug-in hybrid technology, oilable and electric, with the advantage of being rechargeable and directly on the green card, and it can also be exempted from purchase tax, and the overall purchase cost is lower. In addition, dm-i equipped with lithium iron phosphate blade battery is also a highlight, higher safety. The Corolla dual engine is only a hybrid model of oil and electricity, and it does not support charging and cannot be on the new energy brand. For consumers in limited-license cities, Qin PLUS DM-i will be a more suitable choice.
"There are only two hybrids in the world, one is Toyota and the other is the other." Now I think we can add a third, that is, BYD, DM-i super hybrid technology has been comparable to the mainstream joint venture hybrid technology, and even has more advantages in some data.
Next, let's take a look at the comparison of power performance, Qin PLUS DM-i long endurance version is equipped with a 1.5L engine + EHS145 motor, of which the engine compression ratio is as high as 15.5:1, and the highest thermal efficiency can reach 43.04%. The maximum power of the motor is 145 kW and the peak torque is 325 N·m. Yiche's actual measurements have obtained that its acceleration from 100 kilometers takes only 7.2 seconds, and the acceleration performance is quite outstanding.
The Corolla twin engine is equipped with a 1.8L Atkinson cycle engine + E-CVT, the system's comprehensive power is only 90kW, and the maximum thermal efficiency of the engine is 40%. The acceleration time of 0-100km/h measured by Yiche is 11.2 seconds, which is 4 seconds slower than that of Qin PLUS DM-i, and the speed acceleration ability is relatively average.
In contrast, the overall power level of Qin PLUS DM-i is much stronger than that of the Corolla Double Engine, and the 7.2 seconds to break the hundred is also the existence of the best in the same class of models. If you are pursuing more passionate power performance, then Qin PLUS DM-i is undoubtedly a better choice.
In addition to the strong fuel saving power, space is also a car purchase factor that family users focus on. Both models are one of the representative models of compact and comfortable car, and both have a good spatial performance.
In terms of body size, qin PLUS DM-i has a length, width and height of 4765/1837/1495mm and a wheelbase of 2718mm, while the corolla twin engines have a length, width and height of 4635/1780/1455mm and a wheelbase of 2700mm.
From the data point of view, qin PLUS DM-i size is fully dominant, especially the length of the car is 130mm longer than the Corolla double engine, the wheelbase is also 18mm longer, and the better body size also makes its seating space performance better.
The Qin PLUS DM-i is equipped with a sporty leather seat with a multi-directional electric adjustment function in the main seat. The rear seating space is also excellent enough, especially the rear horizontal space and head space performance are the leading level of the same level.
The corolla dual engine battery pack is placed under the rear seats, which is not much different in terms of space experience compared to the fuel version model, and the space performance is enough to meet the needs of the family. However, in addition to the top model, manual fabric seats are used, and there is no rear armrest and central headrest, which greatly reduces comfort.
Overall, the two contrasting models have a good performance in terms of space, and both can meet the travel needs of a family. In contrast, the Qin PLUS DM-i is longer in size, more space, and superior to the Corolla Dual Engine in terms of comfort.
Finally, let's look at the comparison of configurations, we choose two models with similar prices as a comparison. The 2021 Qin PLUS DM-i 120km flagship model sold for 148,800 yuan and the 2021 Corolla Twin Engine 1.8L Elite Edition for 143,800 yuan.
The safety configuration of both models is rich enough, Qin PLUS DM-i is equipped with 6 airbags and DiPilot intelligent driver assistance system, and Corolla dual engine is equipped with 8 airbags and TSS smart travel safety system as standard, which can better ensure the safety of drivers and passengers.
In addition, both models are equipped with keyless entry/start system, tire pressure display, automatic parking, electric sunroof, automatic air conditioning, rear air conditioning outlet, intelligent voice control system and other functional configurations, which are sufficient to meet the needs of daily use.
In contrast, Qin PLUS DM-i has more parallel assist, front and rear parking radar, 360 ° panoramic image, mobile phone NFC key, mobile phone wireless charging, remote start, electric leather seat and other configurations, the convenience and safety of the car are higher.
It is worth mentioning that the DiLink 3.0 intelligent network system equipped with Qin PLUS DM-i is more functional and more intelligent; while the Toyota Zhixing Interconnection of Corolla Dual Engine is more general, cannot keep up with the trend of the times, and cannot meet the intelligent travel needs of young consumers.
Full text summary: Both models are the hot selling models in the current hybrid compact car market, whether it is technical level or space fuel consumption, they have come up with convincing performance, which is why they can become explosive models.
Compared with the Corolla Dual Engine, Qin PLUS DM-i has the advantages of stronger power, lower fuel consumption and richer configuration, and can also be exempted from purchase tax to go straight to the green card, which is more cost-effective. Overall, I would recommend buying the Qin PLUS DM-i among the two models at the same price.
