Because it focuses on the core technology research and development of the three major parts, Honda Automobile has always been known as the technical house of the automotive industry, and Honda Dafa is widely favored by users. In the engine field, not only 1.5L/1.8L self-priming, but also 1.5T/2.0T turbo; in the transmission field, it is CVT stepless, DCT dual clutch, AT planetary gear, three kinds of box skills full; once also over the 5-speed parallel shaft transmission, is also a miracle in the industry; four-wheel drive system, SH-AWD is also a representative of the front-facing layout of four-wheel drive; in addition, Honda i-MMD has also opened up new ideas for the field of oil-electric hybrid.
However, as the integrator of "Honda Dafa", in recent years, Guangqi Honda luxury brand - Acura has not mixed well in the domestic market, some people say that the market is because the market of second-tier luxury brands has been absorbed by Lexus, some people say that its products and GAC Honda are seriously homogenized, and some people say that it is destroyed by the "Changan King" car logo. What is the reason for this, GAC Acura does have a weak sense of existence in the domestic market.
Finally, on April 8, GAC Acura officially announced that the brand will stop production & stop selling existing products from 2023, mainly CDX and RDX SUV models, while the owners of active products (including TLX-L, which have been discontinued) will receive corresponding after-sales service in the future in GAC Acura special stores (electrified sales service network) and RELATED channels of GAC Honda. For the majority of Honda fans, if you are interested in Honda's world's first transverse 10AT and Acura SH-AWD vector four-wheel drive, you really have to grasp it tightly.
GAC Acura has launched TXL, CDX, RDX a total of three models in the domestic market in the past six years, the front two and Honda Accord, Binzhi / XR-V are indeed seriously homogenized, but RDX is indeed a real luxury medium-sized SUV, which is not only reflected in the internal and external design, material configuration, but also in its super hardcore "three major pieces".
Moreover, compared with the same level of Lexus NX, Audi Q5, BMW X3, etc., the price of Acura RDX also has obvious advantages, considering the discount of about 350,000 can be properly on the road.
First of all, the engine part, the RDX and Guandao are equipped with honda K20 series 2.0T turbocharged engines, which are the same as the K20 redhead pilots on the Civic Type R, and the 195kW/380Nm book data is completely out of the way for volkswagen EA888, BMW B58, Mercedes-Benz M264. Technically, this engine uses Honda's best i-VTEC variable valve lift control system, which is its super "master" for a long time to dominate the champion of the 2.0L group of Ward's top ten engines.
Honda K20 series 2.0T engine
In addition, because it is a version used in passenger cars, the 2.0T engine model K20C5 is also based on the K20C1, and a balance shaft system is installed in the oil pan, the purpose of which is to suppress resonance, improve the smoothness and NVH performance of the whole machine, although compared to the Civic Type R slightly suppresses the high speed characteristics of the engine, but daily household use, basically do not use so high speed.
Horizontal 10AT
Compared with the ZF 9AT on Honda's crown road, the Honda's self-developed transverse 10AT on the Acura RDX is much hardercore, not only because of the denser gear ratio brought by more gears, but also because the matching of the self-developed 10AT and the self-developed K20 engine is also more mature and stable. This transverse 10AT achieves ten forward gears through four sets of planetary gear sets, and in the high-speed cruise state of more than 100km/h, the engine speed can be reduced to 1500rpm, which is impossible for most 6AT and 7DCT.
1500rpm、90km/h、10挡
At the same time, when the deep throttle needs to be downshifted to speed up, this 10AT can be reduced by 4 gears at a time, from 10 gears to 6 gears, or from 7 gears to 3 gears, with a surging power output of 2.0T at high rotation, this non-continuous downshift brings a sense of push back than the double clutch.
Acura SH-AWD
The same is the front horizontal platform of the four-wheel drive car, RDX used four-wheel drive system is also very different from the crown road, this car is equipped with Acura exclusive SH-AWD vector four-wheel drive, TA is not relying on the central differential for the torque distribution of the front and rear wheels, but through two sets of electromagnetic clutches directly to the rear axle action wheel to provide power output, the rear axle can get up to 70% of the torque, the minimum load will also have 10%, and between 70% -10% stepless adjustment, Isn't it a bit of an Audi Quattro flavor?
Torque distribution is provided by two sets of multi-plate clutches
Although the RDX is an SUV born on a transverse platform, because the rear axle can obtain a larger torque output (which is not possible with traditional timely four-wheel drive), the driving experience of the TA is more biased towards the rear-drive model, which is what Guandao, Highlander, X3/GLC can't do. In addition, two sets of limited-slip differentials capable of distributing up to 100% of the wheels on the separate side of the rear axle, somewhat akin to "active steering", are also more reliable in the face of intense driving or complex contours, which is also more reliable than traditional four-wheel drive with electronically limited slip on wheels.
●Summary:
Everyone has a different understanding of high-end cars, some people recognize mercedes-Benz luxury cockpits, some people recognize Audi's light show, and some people recognize Lexus tone. But in the author's view, only "advanced technology" is the core competitiveness of high-end cars, Acura RDX is undoubtedly worthy of the aura of luxury cars, unfortunately, in today's era of electrification, Acura focusing on mechanical black technology and power control experience, has been a bit of the Meiji Restoration background "the last samurai" of the sense of loneliness, more and more consumers feel that equipped with Toyota THS hybrid system Lexus NXS 300h is the future, Acura's shine may only exist in the heart of Honda fans.
