Hello, teacher, would you like to ask whether the engine of the cast iron cylinder block is good or the engine of the aluminum alloy cylinder block is good? What is the difference between the two except that the production materials are different?
A - There is no one better than anyone else, only that each has its own advantages. In addition to the Volkswagen EA888, the current major brands are mainly promoting aluminum alloy cylinder block, although the strength is almost interesting, but it can also cover the entire car cycle, so that its lightweight, heat dissipation, not easy to oxidize (rust) and other advantages are highlighted.
For Volkswagen, even if the fourth generation EA888 (domestic has not yet entered service) is still a cast iron cylinder block, not a backward Mass technology, mainly considering the golf R, Audi S3 these transverse platform performance vehicles high power requirements, can complete the strength of the whole machine with lower process requirements, which is not easy to do with the aluminum alloy cylinder block.
For example, the Mercedes-Benz M139 needs to use a cold hard casting process to strengthen the strength of the aluminum alloy cylinder in order to hold the AMG 45 series engine irritable output, so the process is obviously unable to mass-produce M139, so the capacity of the AMG 45 series is very urgent. The simple and rude technical solution of EA888 has no worries in this regard, and you can understand it as "vigorous miracle". Therefore, for ordinary Volkswagen cars using the EA888, the cast iron cylinder block has become a benefit of later modification and upgrading.
How about Leiling? Trouble teacher to evaluate it.
A-Leiling this car can only be said to be a trustworthy family car, easy to drive, durable, low cost of late car maintenance, etc. are its core advantages, but you do not have the luxury of finding what outstanding highlights in it, the interior is ordinary, the space is ordinary, and it is ordinary to drive. Just like the image of an affordable man, it looks ordinary, but the highlight is that he will live a life.
Looking at the Yingshipai, the trouble teacher commented on it.
A-Accord's hull change, quality is not faulty, reliable and durable, Honda 1.5T + CVT is also famous in the same type, VTEC variable valve lift is Honda's housekeeping technology, high speed stability and power response are better than only variable valve timing small displacement 1.5T.
After all, the Tomoto Yingshi school is not as loud as the Accord, and the price has certain advantages, which is suitable for consumers who value the cost performance. Of course, if you look at the low-speed power response, you can also look at the SAIC Volkswagen Skoda speed, EA888 2.0T low power although the data is not good, but with the DQ380 dual clutch, low speed will still be more brisk.
Teacher, how about the Haval H9 car, how about the quality of the whole vehicle, how about the riding comfort, and how cost-effective is it? And tank 300, which is more recommended?
Although the A-Haval H9 and Tank 300 are both non-carrying hardcore SUVs with body, the level includes completely different styles. The Haval H9 is somewhat similar to the style of the Land Cruiser, which can be off-road, but it can also ensure enough riding comfort (driving with some boat feeling); the tank 300 is much smaller in terms of size and level, it is more similar to the Wrangler's car, more backwards to off-road, the playability is also relatively high, and the potential for later modification is greater (although it is more comfortable than the Wrangler).
If you choose a car, it is often necessary to take your family out to play, such as going to Tibet, it is obvious that H9 is more suitable for you, suitable for long-distance crossing, after all, its space and comfort are stronger than tank 300; if you just buy a car to travel, it is more recommended that tank 300, playability is higher, it will be better to drive on paved roads, and fuel consumption is much lower than H9.
Q&A column is updated every working day, everyone has any questions about the car can be left below the column to ask questions (not the dialog box of the public number Ha, easy to leak), we will arrange the answer in order, no answer to please be patient, sometimes more questions will be ranked to the second or third day, keep an eye on it ~
