As the brand's first pure electric medium and large SUV, BMW iX has an avant-garde shape, cool configuration and excellent power system, and is also BMW's first pure electric vehicle equipped with BMW xDrive intelligent all-wheel drive system.
As the most unyielding "sport" in the BMW bloodline, the performance of a pure electric medium and large BMW SUV model naturally makes many people very curious about its performance. This time we got the test drive first and saw how the 2022 iX xDrive50 performed.
BMW iX xDrive50 as the current iX series of models, the battery pack is 111.5kWh, WLTP pure electric endurance of 630km, the total output power of the front and rear dual motors reaches 524 Ps, the official 0-100km/h acceleration time of 4.6s. Although such acceleration is not extremely violent in the field of pure electricity, the maximum power of 385kW and the peak torque of 765N·m are also comparable to 4.0T fuel engines, which is enough to make the iX xDrive50 a member of the "5-second club".
If it is only described as "enough", it does lack respect for the iX pure electric flagship. However, as a flagship model, iX's own positioning is undoubtedly still based on daily driving, violent data, comprehensive lightweight body and gentle tuning, all make iX very "relaxed and comfortable" to get started, excellent smooth performance, without the feeling of driving a behemoth, is the deepest impression it left on me.
In addition, the steering wheel of the iX is very gentle, and the steering is not as heavy as BMW's fuel car, but the reaction speed of the front of the car is still very flexible, which makes people feel different controllability, and the delicate sense of road and precise direction are retained.
In the driving mode, the BMW iX gives the user 3 options: personality mode, sport mode and energy saving mode. The iX's energy-saving mode tuning is no different from the "standard mode", the response of the acceleration pedal is very linear, the power output of the initial section is relatively soothing, gently stepping on the electric door, there is no suddenness of a step on the channel, so the gentle smooth output perfectly "masks" the violent parameters of 524 Ps.
The reason behind this is that bmw calibrates the power output logic of the motor drive for the iX, and the front motor rarely intervenes when gently and normally driving, so that the iX still has the fun of BMW's traditional rear drive.
In addition to the standard mode, when you want to enjoy the passion of driving, one foot "stomps" on the iX's electric door pedal, the front motor immediately intervenes, iX can transmit the acceleration sensation to the driver at any time, just step on the accelerator pedal to release maximum torque, which is also a major advantage of driving an electric car. However, the energy-saving mode has a limited twist setting, and the iX's dual motors are still reserved, but the push back feeling is equally fierce.
Once switched to sport mode, all the restraints were lifted, the feel of the steering power and the reaction speed of the accelerator pedal changed, and the full output of 385kW and 765N·m brought a stronger sense of pushback, completely unlike such a huge electric SUV, so violent that it can be said to beat the X5M and many traditional fuel high-performance SUVs.
Of course, BMW also intimately prepared an electronic analog sound wave to match the acceleration process, so that people can also enjoy the passion of speed in their hearing.
Zero hundred acceleration test, open the sport mode, iX power is more than 80%, after releasing the brake pedal by ejection, the front and rear dual motors immediately release power at full power, the front of the car has a significant rise, the initial acceleration is very rapid, and the output of the rear section is violent but relatively "mild".
The final result, 0-100km/h acceleration time is 4.49 seconds.
Since there is no shift mechanism, which means that the acceleration process is smooth and linear, the strong acceleration brought by the torque of 524 Ps and 765N·m is very extreme in each speed range, without the roar of the engine, you can feel the wind noise that gradually increases as the speed increases, and the pleasure of "the soul is fixed in place".
In terms of braking performance, iX is equipped with a set of Bridgestone top-of-the-line SUV tires with a specification of 275/40 R22, but thanks to the advantages of 275mm wide tires, iX measured braking from 100km/h to stop, with a minimum braking distance of 35.95 meters.
When fully pressing the brake pedal, the braking force release of iX is also very "refreshing", stable, can feel sufficient braking force, after 10 consecutive braking tests, whether it is the brake foot feeling or the performance has not appeared thermal attenuation, the performance release of the braking system is strong and stable, the average performance is stable at 36.65 meters, the fluctuation is extremely small, compared to this big man is really excellent.
At the same time, in the process of full braking, the posture of the iX body is also very stable, and the support of the body with full of toughness is very good, and there will be no forward and backward tilting phenomenon, giving people a very confident driving feeling.
BMW iX still uses a chassis design of double wishbones + five links, and the front suspension is also blessed with air suspension, and the suspension setting is consistent with its own fuel vehicle. At the same time, the suspension is also a sonorous and powerful response, and the integrity of the chassis is extremely strong, continuing the sports spirit of BMW.
As a project to examine the strength of the chassis - winding the pile, elk test, can iX deal with it with ease?
The answer is yes, even if the iX is BMW's largest pure electric model, BMW engineers still tailor it in addition to the ultra-high sports limit, four-wheel follow-up steering and rear wheel 3.2° steering assistance, making the vehicle's steering more flexible. In the adjustment of the chassis, the lateral support is very sufficient, which brings a very tight and resilient overall feeling.
However, the BMW iX still gives the driver a bit of confusion in the Elk test, which stems from the fact that the air suspension provides good lateral support and can fully absorb the energy during the transfer of the vehicle's center of gravity; the tires also provide excellent grip performance, all of which hints to you its strong sport handling and gives you plenty of confidence.
iX in the process of rapid access to the corner is clean and sharp, the transfer of the center of gravity is neat, the timing and strength of esp intervention are very moderate, and there is no premature "forced takeover", the huge SUV body roll is relatively small, the attitude has not significantly shifted, the dynamic response made is beyond expectations, showing BMW's strong sports genes, and the final test score is 72.24 km/h.
However, the huge figure of more than 2.5 tons still drags its feet, even with the xDriver, the perfect counterweight of 50:50 and the lower center of gravity of the electric car, the weight has become a big burden when the vehicle moves fast, and the huge inertia limits its maximum pass speed in the elk test, but it can still score a high score for the excellent chassis mechanical quality of the BMW iX.
The iX has no engine noise as a pure electric vehicle, but the original factory will be equipped with an alternative sound effect, which is still very pleasing, and the noise test is 37.1 dB when stationary.
During driving, the low- and medium-speed cruise basically can not hear any tire noise and wind noise, 50 km/h, the test value is 49.2 dB; 80km/h, the test value is 54.1 dB, basically can also ensure that the front and rear passengers have a relatively quiet space.
When the speed reaches 120km/h, the engine noise and wind noise are also good, with the increase of vehicle speed, at this time the tire and the ground friction caused by the low frequency road noise increases, but the decibel meter collected data fixed at 62.1 dB, high-speed cruising wind noise, tire noise shielding is also very good, it can be said that the legal speed limit can bring a very pleasant quiet experience in the car.
Bmw iX runs through the iconic design language of the BMW i family, with narrow LED headlights on the front face and a huge closed double kidney grille, all of which are highly recognizable, making people intuitively perceive that this is BMW's electric vehicle.
A large closed grille with a large number of cameras, radar and sensors integrated underneath it allows the iX to support L3 level autopilot assist functions, making it safer and smarter. The exaggerated air duct design that surrounds the concave on both sides is naturally integrated into the design of the front face, making the iX present a sharper sense of futuristic atmosphere.
The one-piece roof combined with the slipback shape presents the effect of a suspended roof for the iX, and further optimizes the aerodynamic performance of the vehicle. In terms of size, the BMW iX has a length, width and height of 4955/1967/1698mm, and the size is basically similar to the BMW X5 and Mercedes-Benz GLE, and the wheelbase of 3000mm is also luxurious enough.
At the same time, the addition of frameless doors for the first time brings a charming and dynamic atmosphere.
In terms of interior, the interior of the iX is more luxurious than any BMW fuel model at this stage, and the new style of geometric polygonal sports steering wheel and curved large screen with a new style of luxury with a sense of technology.
The 12.3-inch dashboard on the center console and the 14.9-inch touch-type curved display are fixed in a hidden bracket with a frameless design, which is very modern and homely.
Compared with the existing BMW models, the number of physical buttons in the car has been reduced by 50%, replaced by the more technologically attractive "Shy Tech". Located on the wooden center console, the iDrive control knob is made of glass, like a crystal artwork, and the same material also has a gear handle and seat adjustment buttons, which makes the fashion sense and quality in the car comprehensively improved.
In addition, environmental protection is a feature that BMW iX strives to create, with the central control panel made of sustainably produced FSC certified wood, while the center console, door panels and seats are made of leather materials made of environmentally friendly extracts over a large area, and the hues echo the body.
As a C-class luxury SUV, bowers & Wilkins 4D surround sound system can not be absent, and this set of speakers also has an active noise cancellation function, which can offset the noise coming in from the outside according to the real-time situation.
In terms of space experience, the space in the front and rear rows of the iX is very abundant, and the shape of the seats is very novel, the leather seats emphasize the sense of wrapping, the sense of riding is very comfortable, the leather touch is delicate and warm, and it has heating and ventilation functions.
However, the backrest angle in the back row is somewhat too vertical. Although the BMW iX styling style is biased towards a coupe SUV, the height of the car is only 1698mm, but the roof of the roof with a control of light transmittance function, so there is no sunshade setting, providing a good space for the overhead.
Of course, the rear row also provides independent zone air conditioning and seat heating, and the middle floor is naturally a "flat" design, which also takes into account the experience of space and comfort for SUVs that consider daily use.
Summary: In terms of performance, BMW is the leader in sportsmanship in the field of fuel vehicles, and the iX, as a high-end C-class pure electric SUV, can complete commuting meekly in the daily use scenarios of the city, and can instantly transform into a "thug", allowing people to enjoy the pleasure of "soul fixed in place".
The iX's aesthetic exterior interior design has undergone great changes compared with the well-known BMW, which has caused a lot of discussion. However, the driving pleasure has been effectively preserved, and the comfort has also set a new standard for the flagship model of the BMW family, which is quite bright in terms of technology, luxury and environmental protection.
At present, all iX series are dual motor versions, and the entry-level xDrive50 has also reached 746,900, and I don't know if the future will complete domestic or other motor versions, further explore the price.
