After driving the Buick Micro Blue 6 PHEV, it completely changed my view on plug-in hybrids. It completely abandoned the traditional plug-in hybrids' inherent ability to regulate oil more and lose the driving pleasure. concept. Now Weilan 6? PHEV not only shows good fuel saving effect, but also brings excellent driving passion. What makes Weilan 6? PHEV so outstanding?
The smooth power output brought by Weilan 6? PHEV is inseparable from Buick eMotion intelligent electric drive technology, which combines E-CVT intelligent electronically controlled continuously variable transmission, high-performance dual-drive motors, and LG batteries The ternary lithium-ion power battery and the 1.5L DVVT four-cylinder engine specially developed for hybrid power are organically integrated. Each drive unit performs its duties according to the driving conditions, allowing each drive unit to remain in the most efficient output range. It also brings hearty driving passion.
The Weilan 6? PHEV uses a 1.5L naturally aspirated engine + an E-CVT transmission with dual-drive permanent magnet synchronous motors to form a front-wheel drive, which is also the current mainstream drive form of PHEVs. For hybrid models, the requirements for the engine are even more stringent, which is to give full play to the engine's fuel economy and not deliberately pursue the power explosion at low engine speeds, because the high torque characteristics of the motor at this time are enough to make up for these deficiencies. There was a war between hybrid and turbo engines 10 years ago. With the advancement of automotive technology, the future trend in the field of small-displacement engines is that plug-in hybrids will have the upper hand.
The 1.5L DVVT naturally aspirated engine equipped with the Weilan 6 PHEV can produce a maximum power of 75kW and a peak torque of 143Nm. Together with the GM E-CVT, the maximum power/torque is 82kW/289Nm main motor and The auxiliary motor with a maximum power/torque of 49kW/116Nm brings a better power burst, bringing a combined maximum power of 135kW and a maximum torque of 380Nm to the Weilan 6? PHEV, allowing it to accelerate from standstill to 100km/h in just 8.6 seconds. , naturally brings passion for driving.
The E-CVT intelligent electronically controlled continuously variable transmission equipped with the Weilan 6? PHEV integrates two sets of high-performance AC permanent magnet synchronous motors, General Motors’ patented double-row planetary gear set, and industry-leading power Power Split technology. Weilan 6 PHEV is more than just the above. With the support of industry-leading power split (Power Split) technology, the E-CVT continuously variable transmission will continuously control the engine power in the full speed range and under all working conditions. The energy combination of the power source and the motor power source enables free switching between more than 10 different working modes. It can continuously optimize the energy combination of the engine and motor power sources in the full vehicle speed range and under all working conditions, achieving the ultimate Smooth power output and more efficient braking energy recovery. In actual driving, you can feel that the engine intervention process is very concealed, and you will not be aware of it at all, and it will be as smooth as flowing water. The E-CVT transmission will not let you feel the critical point, nor will it let you notice the shift delay and frustration of any traditional fuel vehicle.
When the vehicle enters high speed or accelerates rapidly, the 1.5L engine will intervene in time to perform work. At this time, the main motor + auxiliary motor built in the E-CVT continuously variable transmission will select according to the current driving conditions. Participate in driving or generating electricity. The core of this technology is that through GM's unique double-row planetary gear set structure, the engine and motor can 100% participate in the drive. Compared with other plug-in hybrid technologies of the same level, it has a higher degree of freedom, a wider transmission range, and a high-speed driving range. More efficient. In the past, hybrid models were always afraid to talk about their fuel-saving performance when driving on the highway. Now Weilan 6? PHEV has admitted that it is equally fuel-efficient when driving on the highway. Manufacturer's data shows that Weilan 6? PHEV has a comprehensive fuel consumption of only 1.4L per 100 kilometers, and the pure electric cruising range has reached 60km, and the comprehensive cruising range has reached 780km. It not only saves a lot of money for daily commuting, but also does not fear long-distance travel.
As for consumers’ concerns about the safety of the three batteries, Weilan 6? PHEV is also reassuring. Its ternary lithium-ion battery cells come from LG Chem, and the battery pack has passed the new General Motors battery that far exceeds the national standard. Energy safety test certification, the unique cell-level intelligent temperature management system also uses General Motors' patented lamellar liquid cooling technology, effectively ensuring the consistency of the cells and the battery's ability to maintain an ambient temperature of -35~55℃ Stable performance, no need to worry about battery danger in high temperatures in summer. The battery pack's sealing design reaches IP67 level and has passed multiple test certifications of General Motors' global new energy safety standards that are several times higher than the national standard, ensuring ultra-high safety and reliability.
Because of an excellent eMotion intelligent electric drive technology hybrid drive system, we are impressed by the Buick Weilan 6 PHEV, and it also gives us a new understanding of plug-in hybrid vehicles.
