[YesAuto Professional Evaluation] Speaking of the Gaoshuaifu among the independent brands, in addition to the FAW Red Flag that can be immediately thought of, SAIC Roewe can also be regarded as a high-end, high-end type. SAIC used shrewd marketing methods and several mature products to build Roewe into a high-quality domestic product comparable to the joint venture brand. The 2013 Roewe 550 in front of us is the most important new product launched by Roewe this year.
This is the first major facelift of the Roewe 550 in the five years since its launch. The appearance does not seem to be much different from the old one, but our focus will obviously not stay on the outside. The 6-speed wet dual-clutch transmission that consumers love to see The box is the focus of this test.
Appearance: Not much change, but everything is changed just right
Roewe 550 2013 Model 550S 1.8L Automatic Qizhen Edition
Roewe 550 2013 Model 550D 1.8T Automatic Edition
It is no exaggeration to say that the success of Roewe 550 in China is largely due to its excellent appearance design. Therefore, the clever SAIC designer did not make a big deal in the mid-term change. LED daytime running lights and light guide taillights were cleverly integrated with high-tech design elements, which immediately gave the 550's already popular shape a new look. In addition, The shark fin antenna on the roof and the single-sided dual-exhaust surrounded by chrome also make the 550 look more refined.
In addition, almost no changes have taken place in other places, which is equivalent to a successful micro-surgery. It seems that there is no change, but a few finishing touches make the 550 rejuvenated, especially the coquettish LED daytime running light. , The texture really doesn’t look like a domestically produced car with hundreds of thousands.
In order to distinguish the level of configuration, the 1.8L model uses 16-inch wheels, and the 1.8T uses 17-inch wheels. The wheel styles are also slightly different. For the tires, the 1.8L model is equipped with Magis’ MA651 series tires, with specifications of 215/55 R16. The price is about 640 yuan per piece on Taobao, which is a common set of tires in self-owned brand models. 1.8T uses the Goodyear Royal Series very kindly, the specification is 215/50 R17, and the Taobao market price is 760 yuan. Although the two sets of tires are of the same size, you get what you pay for. The difference in performance is still obvious, which I will explain in detail in the performance test later.
Interior: the design remains the old style, the workmanship is still excellent
The newly designed instrument panel looks more dazzling than the old model. The style is a bit like the Volvo XC60 that has just been remodeled. The speedometer is fully digital, and the display of the trip computer is more concise and easy to understand. In addition, the entire dial supports three types. Custom color matching is a small detail that can please young consumers.
The workmanship of the steering wheel is very good, and the leather and stitching are very textured. The multi-function button design uses a combination of scroll wheels and buttons, which can realize the functions of driving computer, cruise control and song/radio switching. What makes me puzzled is that the steering wheel multi-function buttons can control so many functions, but there is no basic volume control adjustment. This design obviously lacks consideration.
The multimedia entertainment system has also been upgraded, and the audio decoding function is quite powerful. I tried various mainstream audio formats, such as MP3, Apple's AAC or lossless FLAC. There is no pressure on this system. The entire touch screen system is less difficult to get started, and the screen resolution is also very good. The only problem is that the system is slow, and it often takes several minutes to read a U disk or SD card with a large storage capacity. In addition, since SAIC's main inkaNet system has not yet opened its service, it can only be left to give you a detailed experience in the future.
The texture of the Nappa leather seats is very good. The fine stitches and stitching show that the cost is not low. The overall texture is even stronger than most joint-venture brands at the same price. The seat padding is of the tougher type, the wrapping is average, and the comfort is not bad. Although the texture is great, there are some small deficiencies in the ergonomic design of the front and rear seats.
First of all, let’s take a look at the front row. The main driver's seat of high-end models provides 8-way electric adjustment with lumbar support. The problem lies in the design of the buttons. The front and back of the seat cushion and the upper part of the height adjustment button abruptly add an intrusive decoration. You need to put your fingers in a small slit to adjust it, which is very inconvenient to use. This is a typical case of sacrificing practicality for visual effects, and the user experience is very poor. In addition, the height adjustment range of the seat is too small, even if it is adjusted to the lowest sitting position, it is still too high. When the 182cm tall brother sits in the front row, there is almost no headroom.
Relatively speaking, the comfort of the rear row is better, the seat cushion is long enough, the leg room is ample, the central armrest is also very comfortable, and it is very kindly equipped with a rear exhaust air vent and an ashtray. However, in order to alleviate the problem of the height of the carriage, the height of the rear seat cushion is a bit too low, and the comfort is difficult to guarantee at the same altitude as the bench.
There is plenty of storage space in the car, and two USB ports are generously designed. Although the storage compartment on the left is not convenient to use, one more is always a good thing. In addition, the armrest box is designed with an air-conditioning outlet that can be used to refrigerate beverages, which is suitable for canned beverages.
There is enough space in the trunk, and the rear row supports 4/6 splitting and laying down, but the trunk opening is narrow and high above the ground, it is more laborious to pick and place some large items.
In terms of power, the new Roewe 550 still uses two 1.8L and 1.8T engines code-named Kavachi. Both engines are equipped with mainstream DVVT intake and exhaust variable valve timing technology. They are made of all-aluminum cylinders. It is different from the old model in tuning. The 1.8L engine has a maximum power of 133 horsepower/6000rpm and a maximum torque of 170 N·m/4800rpm, while the 1.8T engine has a maximum power of 160 horsepower/5500rpm and a maximum torque of 215 N·m/2000-4500rpm. In addition, SAIC also gave this The two engines have added an automatic start-stop module to reduce fuel consumption and emissions.
The gearbox is the part that everyone wants to know the most. The 6-speed dual-clutch gearbox, code-named TST, uses a wet dual clutch from BorgWarner, and SAIC has participated in the development of shift logic. The reason for SAIC's use of wet clutch is also very simple: from the perspective of product reliability, the wet dual clutch gearbox is obviously a more reliable choice.
Although there is only one turbo difference between 1.8L and 1.8T engines, the difference in personality and ability is very obvious. In order to protect the dual-clutch gearbox, neither car is allowed to use too high speed (1.8 is 2500rpm, 1.8T is 2000rpm) at the start, and the low-torque and strong 1.8T model has the advantage at the start. The gap is getting bigger and bigger in the end, and the final acceleration result of 1.8T model (10.06 seconds) is nearly 3 seconds less than 1.8L model (12.99 seconds). The results of the two cars are not very good, basically in our expectation, they belong to the standard level of cars in the same class.
The shift speed of the dual-clutch gearbox is quite satisfactory, the ride comfort is acceptable, and the logic protection program is relatively well done, and there is no strike after multiple tests. Of course, this is also the most basic quality that a well-designed gearbox should possess.
In the brake test, the tire gap is very intuitively reflected. The 1.8T model using Goodyear Yucheng tires is heavier, but the braking performance of 40.16 meters is considered excellent, and the tire grip is significantly better. For the domestically produced Magis, the 1.8L model with a lighter weight only achieved 43.05 meters due to poor tires. In addition, the two cars tend to run slightly to the right during emergency braking, and the spring foot of the brake pedal ABS is also more obvious.
The character difference between the two cars in daily driving mainly comes from the engine. The 1.8L model is a good gentleman. In D gear, it is more like a certain ECO mode. The throttle response is slow, and the gearbox is keen to upshift. Under the hard work of the gearbox, the engine speed is always controlled at about 1500rpm, and it seems weak to increase the speed.
Only by slamming the accelerator, the gearbox will lazily react to downshifts. It is worth mentioning that even in the full throttle state, the gearbox does not have the function of directly down 2 gears. Fortunately, you can also choose S gear and manual mode. In S gear, the gearbox will automatically go down to the next gear, and the power will immediately improve after the speed is raised above 2500rpm.
The 1.8T model has a much more active personality. The powerful low torque makes daily acceleration and overtaking seem effortless, but the feeling of turbo intervention after 2000rpm is still slightly abrupt. Although the sudden emergence of power will not catch you by surprise, it does not have 1.8. The linear and smooth feeling like the L model.
The overall performance of the dual-clutch gearbox is satisfactory, with excellent gear shifting smoothness at ordinary times, but the downshift response is slow. There is occasional intrusion when switching low-speed gears. This is also a common problem caused by dual-clutch, which belongs to an understandable category. As an independent dual-clutch gearbox, its performance is obviously better than BYD's 6-speed DCT gearbox.
What's weird is that this dual-clutch gearbox must shift the gear lever into S gear and then move the paddle shifter to enter manual mode. The D gear paddle is completely inoperative. Entering the manual mode directly from the paddle shifter is a practical function that many models with paddle shifters have, but it is completely unavailable on the 550, which is really a pity.
In terms of chassis and handling, the adjustments of the two models are basically the same, and they are biased towards a comfortable home style. The steering assistance is moderate, the front of the car does not respond quickly, everything is designed for daily driving, the throttle and brakes are gradual adjustments, and you will not feel tired when using it in traffic jams.
The multi-link suspension structure of the front and rear Macphersons is rare in today's compact car market, and the 550 is one of the few that still adhere to this high-cost suspension. The suspension adjustment is soft, but still has a certain degree of toughness. After some large potholes and bumps, the suspension can well isolate the vibration from the outside of the car. However, due to the low damping of the shock absorber, it cannot hold the spring well, and the body shakes more after bumping.
In terms of handling, the 550 performed moderately. The support of the suspension was fair, and the tail tracking was good, but the head pushing situation was more serious when it was close to the limit. Once the body exceeded the limit, the intervention of ESC was bold and resolute, and the intervention of the driver was quite obvious.
Questions about the start-stop system
This year, the automatic start-stop system is not a new configuration in independent brands, but it is the first attempt to pair with a dual-clutch gearbox. The system on the 550 should be said to have both advantages and disadvantages. The advantages are obvious, that is, the vibration control of the engine when starting and stopping is quite smooth.
The disadvantage is that the match between the start-stop system and the gearbox is not mature enough. The key to the problem is that when the engine enters the stalled state, the dual-clutch gearbox will disconnect the clutch from the engine. After re-ignition, it takes about 1-2 seconds for the clutch to reconnect. So if you give the oil immediately after the engine is ignited, the dry oil will not go away, and when the clutch is reconnected, the oil explosion just now will give you a surprise start. If this happens on an uphill slope, it will still slip the car slightly, so the user experience obviously needs to be improved.
Fuel consumption test, because the tire width used by the 550 1.8L and 1.8T models is the same, the difference between them is only in the form of engine intake and the weight of the vehicle, so we use the same route and driving style for the two vehicles at the same time. Let's conduct a fuel consumption comparison test, by the way, let's take a look at the difference in fuel consumption between the two different air intake methods.
In the entire fuel consumption test, the two vehicles drove a total of about 110km, and the mileage included 50% of the congested roads, 20% of the high-speed roads and 30% of the normal loops. The average speed was 27-28km/h, and the final fuel consumption score was 1.8L. : 11.2L/100 kilometers; 1.8T model: 11.1L/100 kilometers.
The final result shows that as long as the fuel consumption of the two cars is basically at the same level as long as they are not driven intensively, the fuel consumption of the 1.8L model with weak power is even higher than that of the 1.8T model because of the small horse-drawn cart. Taking into account the factors of 550 vehicle weight and tire width, as well as the congested road conditions during the test, the fuel consumption of 11L/100 kilometers is a reasonable category, but the addition of dual-clutch gearbox does not seem to significantly improve fuel consumption.
The sound insulation of the 550 compartment is still good, but the noise of the engine is a problem. If the engine exceeds 2000rpm, the roar of the engine will be heard, and the roar will start at 3000rpm. This will affect the mood in daily driving.
to sum up:
SAIC has added many selling points to the 2013 Roewe 550, such as dual-clutch gearboxes and automatic start-stop systems. However, the addition of new technologies will always be accompanied by some new shortcomings. Judging from its actual performance, it can be said that there are mixed results. The smoothness of the dual-clutch gearbox can't pick up too many problems, and the matching with the engine is relatively mature, but the degree of tacit understanding between it and the start-stop system needs to be strengthened. However, being able to follow the trend of the times and join these high-tech configurations is also worth encouraging for independent brands. Only by accumulating experience can we develop more international-standard models in the future.
In terms of workmanship and materials, the 550 maintains a consistently high standard. Although there are still shortcomings in some small details, the high-end feeling exuded from the inside is undoubtedly its biggest advantage over competitors.
Sagitar, Cruze and Octavia are the three main competitors of Roewe 550. Roewe 550 is not dominant in chassis power and configuration. Its main advantage is price. The price is improved through substantial discounts from dealers. This is Roewe's usual trick, and the old 550 has maintained a preferential margin of around 20,000 all year round. At present, there is no discount for the new Roewe 550. There is no price-performance ratio for the new Roewe 550. If you really like the 550, you may wish to wait. I believe that around the end of the year, the discount will be restored to the old level. It is a wise choice. (Picture / Li Yi of the car home)
