Which is more cost-effective than Volkswagen POLO or Swift?

For A0 family cars, POLO and Swift are both very attractive models, with full body lines and fashionable interior design, which are favored by young people. When many people compare two cars horizontally, the engine power of POLO 1.4L is 8 kW less than that of Swift 1.3L, only 55 kW. Why is this? This is due to the different engine design concepts. Generally, the maximum power of Japanese cars is higher than that of German cars, but the torque is lower. Moreover, the torque output curve of German cars is generally smooth, focusing on high-speed performance, while Japanese cars are more focused on dynamic performance at medium and low speeds. It is not enough to talk about these dogmatic things. Let's compare the driving experience with the real car, which is more convincing.

Let's start with Swift. Swift has a compact appearance and a short body, but its wheelbase is not short. Adopting four-wheel and four-corner design not only has good visual effect, but also has certain benefits for improving curve performance and high-speed stability. Sitting in the cab, orange backlight, integrated center console, and volume adjustment on the steering wheel. Start the engine and start in first gear. As long as the clutch is properly controlled, it is not difficult to start at idle speed. After the car starts, speed up the shift, the throttle is very light, the gear is very comfortable, and the shift intensity and stroke are satisfactory. At this time, stepping on a heavy oil, the effect is not obvious, and there is almost no feeling of pushing. At the high speed of more than 4000 rpm, the speed-up rhythm slows down and the engine sound becomes heartbreaking. Loud voice, weak speed, shift gears. After all, it is an engine with medium and low speed, but it still feels peaceful to shift to third gear. It seems to be a deliberate reminder that this is just a car with a displacement of1.3l. Of course, this may be related to the hard suspension. Some cars feel that the rear suspension is obviously pushed because the front suspension is elongated and lifted, and the rear suspension sinks when accelerating. Swift gives people a basic feeling like this. The engine is peaceful. Even if your driving style is radical, you can't get the response of the engine.

What about polo? Is this high-speed and small-displacement engine worthy of the name? Give empty gas first when you get on the bus. Except for a little delay, the engine has good responsiveness, the pointer climbs and descends quickly, and the sound is very comfortable. It feels really smooth! I am looking at the interior at this time, but the workmanship is rigorous. German rigid thinking makes polo fashion taste too weak. There are only four speakers in the car, and the sound quality is good. It feels wonderful to cut into the first gear, and the sense of inhalation reminds people that this is the work of Volkswagen MQ department. When you start, oil your feet lightly and get on the road easily. When shifting gears below 2500 rpm, the engine will feel a little shaky. Try a higher 3000 gear, and it will feel different. The speed is strong and the engine is very smooth. Shift to third gear and try to speed up. Starting from about 3500 rpm, the engine seems to have changed and become extremely active. Looking at the increase of speed, the feeling of POLO's heavy body seems to disappear at once, but when the speed pointer reaches 5000 rpm, the sound of the engine is still beautiful, with no hoarse roar, only high-frequency intake screams, just like a beautiful high-pitched electronic song, which is gratifying. POLO, whose strength is at a disadvantage, feels better than Swift. What's the problem?

It depends on the design and matching of the engine. Compared with Swift, POLO's engine is more balanced and advanced in all aspects, which makes POLO perform very well in the whole speed range. Swift's engine, on the other hand, looks a little old, and the power of 63 kilowatts seems to just stay on paper. What are the advantages of POLO engine in structure and design?

From double overhead camshafts to single cylinder independent ignition, there are also resin intake pipes and electronic throttles. These are all designs that can help improve power. Let's talk about the benefits of double overhead camshafts first. The double overhead engine is superior to the single overhead engine in vibration and noise control. The two camshafts can control the intake valve and exhaust valve respectively, which is beneficial to improve the intake and exhaust efficiency. Moreover, the double overhead camshaft has no rocker arm and can be directly connected with the valve, which makes the valve react faster and more directly at high speed. In addition, the double-top camshaft can reduce the weight of a single valve train, which is also beneficial to improve the response speed of the engine.

Because POLO's engine is not designed with variable valve stroke and timing, it can only make full use of the advantages of double top in adjustment and give full play to the potential of high-speed performance. Relatively speaking, the single overhead camshaft of Swift engine is somewhat outdated, and this structure has long been eliminated in Suzuki's engine family. This also shows that Swift is an old engine. In addition, POLO's single-cylinder independent ignition has the characteristics of low power consumption, low interference and high durability, because each cylinder is equipped with a booster coil, which is equivalent to changing a high-voltage line with a high gear, because what is separated from the distributor is no longer high-voltage electricity, but general low-voltage electricity, thus minimizing the loss of current in the transmission process. The ignition efficiency is high, and of course the engine power is better.
