Blind guess a wave, the same level of French cars and Japanese cars, who is more fuel-efficient?
This time, we don't guess the test fuel consumption of the Ministry of Industry and Information Technology, we guess the actual bear fuel consumption.
In theory, fuel consumption is the ancestral artistic ability of Japanese cars, and it is impossible to lose under any circumstances! After all, the legendary engine technology is there! But if I said that the bear fuel consumption display system of the new Peugeot 4008 has better fuel consumption than Honda Haoying, would you believe it?
What the hell is this, is the French power system not working, what tricks have they played, or what little fuel-saving secrets have the French figured out? Let's start the microscope and see what level this engine really is. Again, the old rule, let's only talk about the actual technical configuration.
EP series engines, are they really old, or are they misunderstood?
If you want to talk about peugeot's power system, ep series engines have to talk about. Every time I mention it, the first thing that comes to mind is peugeot's cooperation with BMW.
(Compared with the original EP engine, the current EP engine has a very significant reduction in size.) The yellow part is the Aisin 8AT gearbox)
(Homologous lift continuous variable technology with BMW, but then BMW developed a short-lived 1.5T three-cylinder engine))
To evaluate whether an engine is advanced, it mainly depends on whether it has leading technology. The hard technology of the EP series engines is mainly reflected in the twin-scroll turbocharging, DVVT variable valve timing, and valve lift continuous variable technology. Among them, the advantage of the double scroll tube is to achieve a clear division of labor in the exhaust of the four-cylinder engine, avoid mutual interference, let each channel be responsible for two mutually affected cylinder exhaust, it is 7% to 8% higher than the inlet and exhaust combustion efficiency of the ordinary single-scroll turbocharger, which can significantly reduce the turbo hysteresis effect and increase the low-speed power of the engine. In the 200,000-class joint venture SUV, this is the only engine with twin scroll tubes. Valvetronic valve lift continuous variable technology compared to Mercedes-Benz CAMTRONIC, Audi AVS, Honda VTEC, etc., to open at a certain speed, the infinitely variable way is more advanced, can directly reduce fuel consumption by 7%.
As can be seen from the figure below, the latest EP engine on the right has a completely different change in appearance and components from the original EP engine on the left. The French lose and lose, on the one hand, they continue to update the engine, on the other hand, they have not established a clear engine generational relationship. Whether it is an engine from more than a decade ago, or the latest engine, the two words of EPs are unified. This is a big loss in marketing!!
(The latest EP engine has been fully innovated in terms of shape, size, parts, cylinder block, water pump, exhaust, turbine, etc.)
In terms of life, the Peugeot China VI EP series engine adopts BorgWarner's anti-jump gear chain transmission timing system, which has the characteristics of longer life. In terms of reducing the additional gasoline combustion loss of the engine, the EP series engine also adopts an electronically controlled full MAP variable displacement oil pump, an electronically controlled thermostat and an electronic water pump. These three technologies were introduced for the first time on the just-released 3.0T V6 supercharged engine of the tank 500. Looking at it this way, you will find that it is not old, but forward-looking use of a lot of technology.
The engine is just a coolie, the gearbox is very critical!
The engine has another companion – the gearbox. However, we are easily deviated by the publicity of some car companies, such as their excessive emphasis on the engine and the silence of the gearbox. The new 4008 series adopts the original imported Aisin 8AT gearbox. This gearbox is definitely a star gearbox in the eyes of fans. Let's put it this way, among the gearboxes of compact SUVs, it says second, and no one dares to say first, including the compact SUV of luxury brands.
Since the Peugeot 4008 car series uses this gearbox, it has a certain historical accumulation. Therefore, in terms of tuning, peugeot 4008 also gives amazing transmission efficiency. In the dismantling test of Chedi, the engine of the new 4008 EP6 is rated at 170 horsepower, and after passing to the wheel, the horsepower on the wheel is 163.2 horsepower, and the transmission efficiency is 96%. In contrast, the transmission efficiency of the electric motor is only 96%. This efficiency, send it a sentence YYDS is not excessive.
Other low-fuel details that are easy to forget have a high cost behind them
A completely reinvented, efficient engine and an efficient gearbox aren't the key to the new 4008's fuel economy. In order to match the fuel economy of the powertrain, the new 4008 also uses aluminum alloy front and rear impactproof beams, aluminum alloy cover, aluminum alloy fenders, and lightweight ultra-high-strength steel to achieve weight reduction. Compared with Haoying, the new 4008 has a wheelbase that is 40mm larger than Haoying, and the body is 112 kg lighter. This weight is already equivalent to the weight of two little sisters. In addition, the new 4008 also uses Michelin-customized e-Tingyue tires. This set of tires is characterized by low rolling resistance and fuel saving, Jingdong unit price of 1000 yuan, in the main sales model fully available.
Combined, the efficient engine and gearbox, a series of visible lightweight weight reductions, and high-end energy-saving tires make the new 4008 qualified for fuel consumption. Some people may be more true, saying that the 0.02L fuel consumption saved by the new 4008 hundred kilometers is equivalent to running 1200 kilometers or running two tanks of oil to save a barrel of white elephant instant noodles. But even without mentioning fuel consumption, the reliability, driving sense, and handling of high-end tires of aisin 8AT can also bring owners a better driving experience.
The essence of the low fuel consumption of French cars is the result of two-way efforts of technology and lightweighting. If you're starting to get interested in French cars, you might as well actually check out the shop. In addition, it is necessary to share that the latest listed Chuangxiang edition of the new 4008, under the official direct price of 167,700 yuan, provides a larger displacement 1.8T EP engine, as well as a supporting official direct sales model, which is more in line with the consumption concepts and habits of young people. In a variety of car purchase programs, it also provides 36 installments of 0 interest, 1 year of new car insurance, three years of value-preserving repurchase, 5 years / 150,000 km of vehicle warranty, up to 7,000 yuan of old car replacement subsidies, lion powder purchase to high subsidies of 5,000 yuan and more preferential activities.
