[YesAuto Test Drive] The 2011 imported BMW 3 Series Coupe version and convertible version have been officially launched in China. A total of 4 engines and 4 body styles have been released for a total of 8 models. Although the new car is only a minor facelift, There are still surprises. In addition to retaining the 320i, 325i and 330i models, the new model also introduces the 335i model, which means that BMW has introduced the latest technology to the non-M series 3 series models and introduced it to the Chinese market. The 2011 model BMW 335i Coupe version and convertible version are also the focus of this article.

Appearance-little change, only LED lights are added

There is no need to describe the appearance too much, because the changes are really small. It seems that German cars always understate the appearance when they make small changes.

The headlights of the 2011 BMW 3 Series Coupe and Convertible models incorporate a new LED turn signal group. A translucent eyebrow like other family members is added to the top of the headlights, and the new models can also be selected at the time of purchase. Equipped with the headlight LED kit, that is, the white circular width indicator light (the normal version is yellow), you will feel its eyes deeper when the day is dark.

China Open also has slight changes. If you observe carefully, you will find that the China Open is flatter and wider than the old model, with two fewer banners and a more symmetrical distribution. The air intake under the front bumper has changed from the original three-hole type to a horizontal through type, and is decorated with silver decorative strips. The above subtle changes make the front of the car look a lot wider than the old model.

The change of the tail is only the combination of the taillights. The LED light group is used in the turn signal, brake light and width indicator light, which has higher brightness and faster light emission. In addition, the all-red design has a strong overall sense. In addition, the styles of the wheels of the 2011 model are also richer, and options are available.

The above are the appearance changes of the 2011 BMW 3 Series Coupe version and convertible version, but these are not the main points, because today we are testing a BMW. A better way is to open it up and feel its inner classics.

A brief introduction to the engine/gearbox technology of the 2011 335i model

Dual-scroll single-turbo design-wide torque range, more economical

Although they are all called 335i models, the engines on the 2011 BMW 3 Series that have just been launched are quite different from the older models. The older models use an inline 6-cylinder twin-turbocharged engine (code-named N54B30). This model uses an in-line 6-cylinder twin-scroll single-turbo engine (code-named N55B30). Compared with the later version of the N54B30 engine, the maximum power of the N55B30 is slightly lower, 306 horsepower at 5800 rpm, but the maximum torque of 400N·m can be fully output from 1200 rpm. In addition, the twin-scroll single-turbo 3.0L inline 6-cylinder engine has better fuel economy.

7-speed dual-clutch gearbox-for the first time on a non-M series 3 series sedan

The most exciting configuration in this test drive is this 7-speed dual-clutch gearbox! This is the first time this gearbox is installed on a 3 series model, which is the same as the one used on the Z4 35i model. This is a qualitative change for the 3 series model gearbox. In addition, the 2011 models of 320i, 325i and 330i continue to use 6-speed automatic transmissions.

Driving experience

High-speed test drive

Take advantage of the high-speed test drive session to experience the midway acceleration ability. First of all, the maximum torque output range of the engine is very wide. The maximum torque platform ranges from 1200 to 5000 rpm, which means that after the car is running, you can get the torque you want at any time of acceleration. The acceleration from 60 km/h to 100 km/h is not a problem for the 335i. If you want to drag the car, you can switch the transmission to manual mode to get a higher shift point.

After accelerating continuously to 180 km/h, the sense of acceleration gradually weakened, and the vehicle speed continued to rise slowly. In high-speed driving, the stability of the vehicle body is still relatively good, but the road feel is clearer. When driving at high speed for a long time, it is easy to produce a sense of irritability due to small bumps on the road.

Field test drive-active steering technology makes steering more flexible

The most experienced in the field test drive is the more sensitive steering. The imported BMW 3 Series Coupe version and convertible version are equipped with an active steering system. The intuitive experience is that when driving at a low speed and turning the steering wheel, the steering range of the wheels will be greater than expected. , The steering wheel can greatly change the direction of the car without turning too much angle. This function is very useful when parking. It should be noted here that flexible steering does not mean low steering strength. It is not light to turn the steering wheel of the BMW 3 Series Coupe.

Term explanation-active steering system

The active steering system consists of a planetary gear and two input shafts. One of the input shafts is connected to the steering wheel, and the other is controlled by an electric motor through a helical gear. When the vehicle speed is low, the control motor rotates in the same direction as the steering column to increase the steering angle; when driving at high speed, the control motor rotates in the opposite direction to reduce the steering angle. The effect is to make parking easy, and driving at high speeds is more stable and safer.

In stationary and low-speed driving conditions, the steering wheel and the wheel rotate at an angle of 10:1

At high speed, the angle between the steering wheel and the wheels is 20:1

In the field test drive link, because of the existence of DTC (body stabilization system), the body posture is restricted very well, and DTC intervenes in a timely manner. If you want to stimulate a little more, turn off the DTC and slightly increase the throttle when turning to make the rear of the car slip slightly. If you have experience and control it well, you can easily create a drifting action.

Mountain road test drive

This is the most interesting part of the test drive that I feel is the most interesting. When I enter the mountains, I can’t help but switch to manual mode when the shift lever. Because of the active steering system and the paddle shifters behind the steering wheel, the driver's hands rarely need to leave the steering wheel even when driving on curved mountain roads. When the two arms crossed during a U-turn, the front of the car basically completed the required steering angle.

If it is fun to use paddle shifts on the 330i model with the 6AT gearbox, then it is a pleasure to use the 7-speed dual-clutch gearbox for the first time on the new 335i model. When driving to the center of a bend, reduce one gear and step on the accelerator while exiting the corner. There is almost no lag in the power connection. And one detail I personally like is that the 335i's rear exhaust pipe is emitted due to the rapid shift of the dual clutch. With a “puff” back pressure, this voice is particularly beautiful in the mountain stream.

However, the first time you need to adapt to driving this car is that if you are not mentally prepared, the intervention of the active steering system may give you a feeling of “overheading” at once, and you need to adapt. In addition, although the momentary power of shifting is seamlessly connected, there is still a short process after moving the shift paddles to completing the shift, which is not as “an instant” as imagined.

After the winding mountain road, the road returned to calm. If the weather is good, we can open the roof and drive at a constant speed to enjoy the fresh air. The estimated time to retract the roof of the 2011 BMW 3 Series Convertible is about 20 seconds, which is satisfactory for a three-fold hard-top convertible with a complicated structure.

In addition, the self-weight of the convertible is heavier than the Coupe model, so it is slightly inferior to the Coupe model in terms of acceleration and handling. According to official data, the acceleration time of the 3 series convertible and Coupe models with the same displacement is 0.3 seconds slower- 1.2 seconds.

Interior—no change in styling, optional accessories are provided

The interior of the 2011 Bao 3 Series model is not much different from the normal version of the 3 Series model, but the unique M logo steering wheel and short shift lever on the 335i model indicate that he is the best one except the M3. 3 series sedan. The interior leather is available in a variety of colors.

The launch of the 2011 BMW 335i Coupe version and convertible version is a transformation of the non-M series 3 series models. It covers all the mainstream advanced technologies of BMW. Of course, the price of the new roof is almost 800,000 yuan. It seems that talking about the price-performance ratio with 335i Something is wrong, but isn't it also a happiness to drive a convertible with the world's advanced technology to enjoy the sun under the blue sky? It’s the inner show. (Photography, Literature/Auto Home Wang Miao)
