When Bitauto Original talks about platform strategy, I think the first brand that most users think of is Volkswagen. From the era of fuel vehicles to the era of electrification, Volkswagen has launched a series of Familiar platforms, such asMQB, MQB evo, MEB, PPE and the upcoming SSP pure electric platform. Not long ago, Audi's pure electric SUV, the Audi Q5 e-tron, was launched. The new car is built on the pure electric platform MEB, with a price range of 395,500-510,000 yuan. At this price, the Audi Q5 e-tron requires The competing products it faces are undoubtedly the BMW iX3 and Mercedes-Benz EQC.
From the perspective of core product strength, AudiQ5 e -tron's maximum endurance is 520km-560km, and the fastest acceleration from 100 kilometers to 6.7 seconds. At the same time, with the blessing of the MEB platform, the Audi Q5 e-tron also maximizes its own advantages, such as better space utilization, better center of gravity distribution, more flexible battery arrangement, and "three-in-one" motor, electronic control, and reducer "High integration, these can also be regarded as the characteristics of the MEB pure electric platform. But objective comments, from the user's perspective, the Audi Q5 e-tron does not show much advantage over the Mercedes-Benz EQC and BMW iX3. Compared with the current independent new forces that can easily reach 1000km+ battery life and even have "10-minute fast charging" , the Audi Q5 e-tron seems difficult to match its starting price of nearly 400,000 yuan.
So can we think about it this way? Is it due to the limited potential of the MEB platform?
Here, I don’t want to use a lot of space to explain to you the technical features of the MEB platform and whether consumers will If you are willing to spend a lot of money to buy a "luxury version of the Volkswagen ID.6", the market will naturally give you the answer. But from the perspective of technical reserves, this does not mean that Audi will lose its identity as a luxury brand in the future. It can even be said that the MEB platform is not Audi’s label, because the one that will continue to support the Audi brand in the cloud will be PPEandSSPTwo major platforms.
Different from the MEB platform for mid- to low-end, the PPE platform It will be the main battlefield for Audi's pure electric models in the future. It is developed by Audi and Porsche. Currently, the models known to be built on this platform include the Audi A6 e-tron and Q6. e-tron and Porsche Macan pure electric version, and the characteristics of this platform are completely different from the MEB platform, such as unique800V voltage and 350kW fast charging poweretc. At the same time, models under this platform will also support four-wheel steering, torque vectoring and air suspension. In summary, it means faster acceleration, longer battery life, shorter charging time and better comfort.
At the same time, The PPE platform supports a variety of models, including cars and SUVs, with wheelbases ranging from 2890 to 3080mm, ground clearance ranging from 152 to 217mm, and wheelbases ranging from 1641 to 1714mm. So you can see here that PP The E platform basically covers the B-D model classification. In other words, Audi's future mid-to-high-end price range pure electric models will basically come from the PPE platform.

With AudiA6 Take the e-tron as an example. It is the first model on the PPE platform. It has a design drag coefficient of 0.22Cd, a maximum output power of 270kW (finally considering cost issues, it is consistent with the J1 platform), a peak torque of 800N·m, and an acceleration of 100 kilometers. within 4 seconds . At the same time, the WLTP cruising range corresponding to 100kWh is more than 700km, and the voltage is 800V. Charging for 10 minutes increases the cruising range by 300km; charging from 5% to 80% takes less than 25 minutes.
Judging from the information currently displayed, the Audi A6 e-tron can fully compete with the current mainstream medium and large pure electric sedans, and its core competitiveness has reached the third place in its class. First-tier. According to Audi’s plan, the Audi A6 e-tron will officially meet with everyone this year.
In terms of battery packs, PPE platforms are currently selectedIt is an SDI solution, which is a square case battery cell. The battery uses an 800V voltage system, the battery energy is 100kWh, and 12 square case battery modules are used. Of course, the PPE platform has made improvements in all aspects of the system, including weight reduction, size reduction, and loss reduction. This is also the benefit of switching from 400V to 800V. It reduces energy consumption and helps improve vehicle endurance.
In addition, the driver design of the PPE platform is also based on modular reuse , the three motors adopt permanent magnet synchronous (the smallest can support asynchronous), adopt different rotor lengths to achieve different power changes, and support IGBT and SiC power chip solutions are divided into four gear ratios (11 to 8.5). The drive system supports 800V voltage and uses silicon carbide modules; the lubrication system uses an electronic oil pump and dry roller skating method to achieve low friction and high energy consumption. The motor uses hairpin and direct oil cooling to achieve high energy, while taking into account the use of rare earths as little as possible.
On the 18th of last month, the price of the Audi Q5 e-tron was announced On this day, the Audi FAW new energy vehicle project was officially launched. As early as a year ago, the Audi FAW new energy vehicle project had settled in Changchun. At that time, it was clear that the introduction of PPE platform. According to the plan, this factory is scheduled to be put into production before the end of 2024. After it is put into production, it will produce models based on the PPE platform, with a planned annual production capacity of 150,000 vehicles. According to outside sources According to speculation, the first model to be put into production at the plant will be the Audi Q6 e-tron.
As you can see from the picture, the PPE platform is currently Volkswagen’s highest-standard pure electric platform , and Audi plans to produce many models on this platform. Of course, in addition to Audi, the pure electric models of the Porsche family will also focus on this platform. It is conceivable that PPE will be the essence of Audi's pure electric models!
If MEB The platform is oriented towards the mid- to low-end, while the PPE platform focuses on the high-end, so the SSP platform is a completely new dimension. According to Volkswagen’s official explanation, “electrification” will give way to “electronization” under the SSP platform.Among them, automotive electronics, software and computer systems will be the core of the platform, because in the public's view, the hardware gap between new energy models will narrow in the future, and the real gap between car companies will be software. This is also the core reason why Volkswagen developed the SSP platform.
SSP, the full name is Scalable Systems Platform. Volkswagen has said that it is a new architecture, autonomous driving and a new production method. The outside world once believed that Volkswagen DevelopmentThe SSP platform is a self-denial of the MEB platform and PPE platform, but in fact the SSP platform can be seen as an extension of the existing platforms MQB, MSB, MLB, MEB and PPE. In addition to bringing L4 In addition to the level of automatic assisted driving functions (2030), including the introduction of standard battery concept, E32.0 software platform, etc., and this is also the fundamental reason for Volkswagen to fight against Tesla. The former toIt is expected to reduce production costs by 50% for the Volkswagen Group in 2030, and the latter E3 The 2.0 software platform is mainly adapted to the SSP platform. It is a universal operating system suitable for all brand models of the Volkswagen Group. By then, L4 level autonomous driving technology will also rely on it. the software platform.
CARIAD CEO Dirk Hilgenberg said: "By 2030, software based on autonomous driving technology will become the main source of revenue for the entire automotive industry." The new, unified software platform version 2.0 covers digital interconnection functions and, together with the SSP platform, is available across the entire group. Deployment will open up a new ecosystem and a new data-based business model.
It is worth mentioning that is based on SSP platform, mass plan launchedTrinity and Artemis projects. The former will be used in Volkswagen Group's sedans and station wagons, and the latter will serve high-end luxury models from Audi, Bentley and Porsche. So, as mentioned at the beginning of the article Say, Audi Q5 The e-tron is just an appetizer, the real killer is at the back. Of course, Audi won’t keep everyone waiting for too long.
Editor’s comment: This is the end of the article, I believe everyone is interested in it! The two major platforms of PPE and SSP already have basic impressions. At the same time, this year, Audi will bring their first model under the PPE platform-Audi A6. e-tron, and judging from the timeline planned by Audi, the PPE platform is the 2.0 era that truly makes it competitive. Of course, this car will have to wait until 2024 to meet Chinese consumers, but we might as well let "Audi Flying for a while.” As for the Audi Q5 e-tron, it is neither a pure electric version of the Audi Q5 nor has much to do with the Audi e-tron GT using the J1 platform. So, what do you think about the Audi Q5? What do you think about e-tron? Or will you wait patiently for the PPE platform?
