  7. Autonomous mid-size car benchmark...

[YesAuto Model PK] In this year's Guangzhou Auto Show, there are two popular autonomous mid-size cars, one is BYD Sirui and the other is Changan Ruicheng. Through experience, these two products have left us with a pretty good impression. Regardless of design or workmanship, space and configuration, they will become benchmark products for autonomous mid-sized cars. What we have to do today is to put them together and compare them. See who is stronger. (These two cars will be exhibited at the 2013 Shanghai Auto Show)

Appearance comparison

Both cars give us a bright feeling, and their exterior design clearly shows different styles. From the perspective of body size, Changan Ruicheng is a lap larger than BYD Sirius. The wheelbase of 2810mm is more in line with the standards of medium-sized cars, while the wheelbase of BYD Sirius is relatively conservative at 2755mm.

In comparison, SIRUI is developing towards the young and fashionable direction, and more straight lines are applied in the design of the whole car; while Ruicheng is relatively mature and stable, and the overall feeling is more atmospheric.

I think the headlights of the two cars have great shapes, and the interior of the headlights is rich in layers, which are obviously carefully designed. In terms of practicability, there is little difference between the two cars. The headlights are equipped with lenses, but the SIRUI headlights have a separate design for the far and near beams. The Ruicheng design is integrated. The far and short beams are switched through the baffle structure. Obviously xenon headlights, and Ruicheng With headlight cleaning, it can bring a certain degree of convenience to driving, and it has obvious advantages in headlights.

The side styling styles of the two cars are similarly different. The SIRUI side is somewhat similar to the BYD G6, which is relatively traditional; I personally like the Ruicheng side. The lines are smooth, and the slender body looks very natural, which is better than SIRUI. Steady and more atmospheric.

The tires of the two cars are similar in size. The Siri show car uses Giti tires with a size of 215/50 R17, and the Ruicheng show car uses Dunlop tires with a size of 215/55 R17. In terms of spare tires, both cars use full-size spare tires with aluminum alloy wheels, which are very practical for most users.

The SIRUI exhaust pipe adopts a double-sided single-out design, which further enhances the sense of movement. The Ruicheng exhaust pipe is only a single-out design, which is somewhat stingy. It can be changed to a single-sided double-out.

The taillights of Sirui and Ruicheng are in line with the style of the vehicle, and the LED light source is added. Both the appearance and the practicality are more mainstream.

Appearance summary:

First of all, we have to admit that the appearance of these two cars has given us a lot of surprises. From the design to the workmanship, they have shown the level of a medium-sized car, which has been significantly improved compared with the models on sale. SIRUI focuses on sporting young fashion routes, and the design is more characterful, while Ruicheng gives us the greatest feeling that the atmosphere is stable, and the body lines are very elegant.

Interior and highlight configuration comparison

    The two cars have a more modern appearance. Compared with the models currently on sale, the workmanship and design have been significantly improved. In the interior part, they also have their own characteristics. Let's take a look together below.

The overall style of SIRUI's interior continues the design of BYD G6, which is very stable and conservative. Ruicheng's interior obviously feels more luxurious than SIRUI. The improvement in interior design is obvious. In terms of materials, SIRUI central control The Taiwan is made of hard plastic, while Ruicheng is made of soft material, which has a good touch.

The steering wheel of both cars feels good, and both have integrated multi-function buttons, but SIRUI is electric four-way adjustment, and Ruicheng is manual up and down adjustment. In terms of practicality, SIRUI is more user-friendly, mainly reflected in the four-way adjustment. Above, for tall people, the use of front and rear telescopic adjustment is obvious, and there are very few electric adjustable cars in this level.

SIRUI’s dashboard uses a full LCD screen design, which is the first of its own brands; Ruicheng’s dashboard is relatively conservative, but it also has a good visual effect.

In terms of configuration, SIRUI has obvious advantages. The center console integrates a 10.2-inch touch screen. The entertainment system has TV, navigation, and DVD functions. The size of the Ruicheng central display is quite satisfactory, and the system has a fast response speed. There is nothing obvious. The shortcomings are that the screen is not as big as SIRUI in comparison, and the functions are not as rich as SIRUI.

In addition, SIRUI is also equipped with a HUD head-up display and night vision system, as well as a 360-degree panoramic image of the body. Few models can compete with SIRUI in terms of configuration.

SIRUI still shows obvious advantages in terms of comfort configuration. Both cars have seat heating, and SIRUI has added seat ventilation on this basis. You must know that many 500,000 cars do not have this configuration.

Space contrast

In terms of riding space, Ruicheng, which has a larger body and wheelbase size, shows obvious advantages. Experiencers with a height of 180cm have two punches in the back row of Ruicheng's leg room, while Siri can only provide one punch and two fingers. Leg room.

The ride comfort in the middle position of the rear row is also the advantage of Ruicheng. The middle floor of the rear row of Ruicheng is very small. Passengers in this position can ride with their feet together, which has little effect on comfort; on the contrary, the rear of Siri The floor in the middle of the row is obviously raised, which affects the ride comfort.

Although SIRUI has a very high configuration, we can only give zero points for the contribution to child safety. SIRUI does not have a child safety seat interface in the rear row. If this mass production is not in compliance with the legal requirements, we guess it is an exhibition. Car sake. Ruicheng performed very well in this regard, equipped with two pairs of ISOFIX child safety seat interfaces.

Both the front and rear rows of the two cars are equipped with two cup holders, and the fixing effect is obvious, which can provide convenience for the front and rear passengers. As the central armrest box in the front row of Ruicheng can be adjusted back and forth, it will block a cup holder when adjusted to the front.

In terms of storage space, Ruicheng is more practical than Siri. The storage tank space on the front door of Siri is larger than that of Ruicheng, and the vertical space is longer. However, the rear door is not ideal, and mineral water cannot be put in at any angle.

The trunks of the two cars are not very different, the interior is not very regular, and the front end shrinks obviously; the opening method of the trunk cover is also very traditional, without air struts, and the details are more thoughtful. The wiring is wrapped in a plastic decorative shell. Inside, it looks more upscale.

Summary of configuration and space comparison:

In terms of configuration, BYD Siri presents an overwhelming advantage, and the configuration level directly surpasses the higher-level models. The 10.2-inch display, HUD head-up display, night vision system and seat ventilation are all its bright spots. In terms of storage space, the two can be said to be basically tied, while SIRUI's rear door storage is slightly inferior. The advantages of Ruicheng's rear-seat ride comfort are obvious. First, the space is large, and the second is that the rear center floor is completely free of protrusions.

Comparison of power and suspension

Both cars use turbocharged engines. Sirui is equipped with the current 1.5L direct injection turbocharged engine on Surui, and is equipped with a 6-speed dual-clutch gearbox. Ruicheng is equipped with a 1.8L turbocharged engine and a 6-speed automatic Gearboxes, these two sets of power systems are good for independent brands, which can bring some surprises while satisfying the family.

In terms of suspension structure, the rear suspension Siri uses a five-link structure, while Ruicheng uses a link pillar structure, while the front suspension is also different. Siri is a double wishbone, and Ruicheng is a MacPherson. Rui has certain advantages, but the actual driving experience and control ability depends more on the adjustment skills.

Summary of power and details:

Turbocharged engines have gradually emerged in independent brands. Sirui's 1.5L direct-injection turbocharged engine and 6-speed dual-clutch gearbox are also equipped on Surui. This power system has direct power performance and relatively rapid output. Ruicheng's 1.8L turbocharged engine does not have direct injection technology, but it is also a mainstream match with 6AT gearbox. In terms of details, the thick thermal insulation wool and double pneumatic struts made us feel very pleased, and we can see the sincerity of the manufacturer.


In general, both cars are good. Both the exterior and interior styles adhere to their own characteristics. The SIRUI sports, swift and magnificent. In terms of configuration, they both show a higher level, which is better than the SIRUI configuration. Rich and powerful configuration is its biggest selling point. The comfort provided by Ruicheng is stronger, the seats are soft, and the space is more spacious. In terms of power, the turbocharged engine with a 6-speed gearbox can fully satisfy the family in terms of power, and it can also bring some surprises. On the whole, Siri and Ruicheng have made very obvious progress compared with the models sold in their respective brands. If the price is reasonable, I think their competitiveness is still quite strong, but in the domestic market, compared with the joint venture medium-sized car, the brand The above is still slightly lacking, and our consumers' awareness of independent brands still needs to be improved step by step.
