Since the automobile was invented by human beings, the joy of handling has become the tireless pursuit of drivers. What is handling fun? For a family car, it is nothing more than precise handling, proper throttle response and just the right push back feeling. But these are all built on the basis of long-standing internal combustion engine-driven vehicles, but there is an irreconcilable contradiction between energy consumption economy and driving pleasure.
So the question is, is there a car that can not only achieve professional-level control, but also take into account energy conservation and environmental protection, so as to meet the car needs of young consumers with cash-strapped money? Have! The upcoming BYD e2, in terms of control, it is difficult to find rivals in the same class of cars, it can also perfectly take into account low-carbon and energy-saving, this pioneering attitude makes users shine, today we will listen to this “pure electric small steel” What sound is there under the appearance of “cannon”?
Lightweight, deep into every “capillary” of e2
There is such a wise saying in the modification industry that advocates control: “It is better to have less than 10 horsepower and no more than 1 kilogram”. For a car, too much weight can lead to problems such as soaring energy consumption, rigid handling, sluggish acceleration or braking procrastination. In analogy to the saying in a marathon that “every 1 kg weight loss by an athlete, the performance will improve by 3 minutes”, if you want to experience the efficiency of how fast, easy and economical, and the gracefulness of being as light as a swallow, the four-character motto of “reducing fat and increasing muscle” is indispensable , and if the car wants to have low energy consumption, run fast, and run far, it is undoubtedly the best choice to start from the curb weight to achieve light weight.
Since the beginning of research and development, BYD has completely followed the lightweight design concept in the creation of the e2. The new car has been built by BYD’s R&D team and supported by the e platform. The highly integrated design achieves the ultimate compression of space and realizes the purpose of lightweight body.
In terms of specific operation, e2 highly integrates the three components of the drive motor, motor controller and reducer in the drive system, reducing the complicated connections between components and the number of wiring harnesses, thus making the overall structure more compact and smaller , The weight is lighter, and the weight is reduced by 25%.
In terms of body structure, the brand-new e2 has adopted 3H high-strength body structure, LCB lightweight platform body structure, a large number of high-strength steel, hot-formed steel and laser brazing roof and other technologies while ensuring sufficient body rigidity. , to further reduce the weight of the vehicle body.
In terms of power batteries that account for more “weight”. BYD adopts a lightweight module design, which increases the energy density of the battery pack while reducing the weight by 44% compared to the conventional design. With the use of lightweight materials for the body, after this wave of “operations”, BYD e2 has successfully reduced its weight. It weighs a staggering 1250kg.
“1250kg”, what kind of concept is this? Compared with pure electric vehicles of the same level of battery life – Geely’s new pure electric model Geometry A high-dimensional standard battery life square version has a curb weight of 1650kg; the 2019 SAIC Roewe Ei5 has a curb weight of 1555kg – there is no Undoubtedly, the lightweight performance of e2 is far ahead in the same class.
With a lighter body weight and the inherent explosive power characteristics of pure electric vehicles, BYD e2 naturally has a handling performance comparable to that of a hot hatch. With a body center of gravity close to 50:50, the layout is more reasonable. In addition to the sense of straight-line acceleration Stronger, the posture of the body in the curve will be more stable, the shift of the center of gravity will always be within the controllable range, and the body will be kept close to the road during high-speed driving. The amazing feeling of splitting and turning allows you to enjoy a different driving pleasure.
Who says control and energy saving can’t have both?
Lightweight can bring a lighter body and better handling performance to car owners, but intense driving that pursues a sense of control can also easily cause increased energy consumption and greatly increase costs. This is why many people like to play with cars, but they are unwilling and unwilling An important reason for daring to “drive cars”, because the high cost of lightweight family cars obviously does not meet the needs of economical and affordable daily cars.
As a pure electric vehicle, BYD e2 has solved the century-old problem of incompatibility between control and energy saving.
Thanks to the low-resistance streamlined shape of the whole vehicle and the application of energy-saving technologies such as air curtains, lightweight, and efficient power systems, the new e2’s driving energy consumption is only 11.3kwh/100km. At present, the household electricity bill in Beijing is about 0.5 yuan per degree, in other words, the electricity bill for 100 kilometers is only 5.65 yuan. The e2 with excellent energy saving effect is even cheaper than the “little blue car” or “little yellow car”!
Compared with SAIC Roewe Ei5, which is also a pure electric car, its official driving power consumption is 13.2kwh/100km, and the electricity fee for 100 kilometers is 6.6 yuan, which means that Ei5 costs 1 yuan more per 100 kilometers than e2.
Compared with Volkswagen Golf, which is known as the “small steel gun” in the market, its 280TSI (1.4T) DSG comfort model has a measured comprehensive fuel consumption per 100 kilometers of about 6.5-8.5L. Here we take the smaller value: 6.5L/ 100km, the price of No. 92 gasoline is about 7 yuan/L, and the running cost per 100 kilometers is about 45.5 yuan. If calculated on the basis of driving 20,000 kilometers per year, the annual fuel cost of a traditional “fuel hot cannon” like the Golf will be about 10,000 yuan less, while the new e2 only costs more than 1,000 yuan.
At the same time, low energy consumption means less pollution to the environment. According to statistics, the emission of 1 liter of gasoline is about 2.25kg of carbon dioxide, while the emission of 1 kilowatt-hour of electricity is about 0.272kg. The result is obvious, and the pure electric e2 for daily travel is more environmentally friendly. Ultra-low energy consumption also means longer battery life. It is reported that the driving range of the new e2 is 300+km, and the high-endurance version is 400+km, which can fully cover the needs of daily vehicles.
Lightness, life of all things, e2 fulfills its talent
The pursuit of low energy consumption for pure electric vehicles is not smooth, and it is impossible to achieve it overnight. It is not easy to balance driving pleasure with low-carbon environmental protection. However, the lightweight e2, which has been carrying the mission of low-carbon and environmental protection since its birth, can be described as extremely talented. Under the construction of BYD’s R&D team, it has successfully fulfilled its talent, pushing the industry forward with perfect control and low-carbon energy saving. A door, under the appearance of “pure electric hot hatch”, e2 is an out-and-out all-round “environmental protection player”.
