When the huge and young cars were spotlighted under the spotlight on the bankruptcy of Saab in Sweden, BAIC Group, which is already “outside the houseâ€, is busy under the first autonomous high-end B-Class sedan based on the Saab 9-5 platform and code-named “C70Gâ€. Preparation before the line.
According to Beiqi's internal plan, with Beijing Auto's high-end production base in Shunyi officially completed and put into production in November this year, the Beijing Auto C70 autonomous vehicle built on the Saab 9-5 platform will be the first to go offline and put into production, and Saab 9-3 as a platform The Beiqi C60 autonomous model built will be put into operation next year as soon as possible. In addition, Beijing Auto's entry-level autonomous sedan and flagship model will also be fully operational in 2014.
On November 30, C70G will go offline as scheduled. On September 26th, this newspaper contacted Ouqi, the Beiqi C70G project manager, through related channels. Ou Yu told reporters that cost reduction was the core job before listing. “Turn a very personalized car into a very popular car. This is Our challenge. Saab's performance is very high, the cost is also high, how to reduce costs is a big problem."
In fact, within the general system, Saab's new 9-5 is technically a platform with LaCrosse. The positioning target of C70G is basically locked in LaCrosse, and technically C70G is still fighting with Saab.
It is worth noting that in the process of digesting and absorbing the platform and technology of Saab 9-5, with respect to change and invariability, as well as drastic changes, the BAIC R&D team's thinking is very clear. As a land vehicle, Saab's powertrain is firmly preserved, and the appearance of minority, especially the body design, has been completely subverted.
Learning from Common Criteria Because Saab is derived from GM, GM's standards have a strong reference for BAIC autonomy.
Beiqi purchased the old Saab 9-5 platform. How to ensure the advanced nature of the C70G built on this platform is a problem that Beiqi must face. "First, we completely changed the model, followed by Asia, and the third technical standard improved. "We use common standards because we buy Saab technology, and Saab itself is universal. A member of the Beiqi C70G R&D team revealed to reporters privately.
From the acquisition to the current 20 months, until now BAIC is still digesting it, but also out of a large number of books including some patent summary. In order to ensure the strength of the R&D team, more than a dozen years of experience in technology returnees have joined BAIC. At the same time, BAIC has drawn some personnel from Beijing Hyundai and Beijing Benz to ensure that people with experience will be able to check the products and processes.
Since Saab is derived from GM, GM's standards have a strong reference for BAIC autonomy. In GM's own product sequence, the standardization is very strict, including Cruze, Regal, and Cadillac all have completely different standards, while the Saab 9-5 standard is between Regal and Cadillac.
"Common standards, we will use them for comparison. If some standard Cadillac is better, we will lean on it. Swedish Saab engineers will also give suggestions in this regard. Although we buy Saab products are not the latest , but we are implementing the latest standards."
So how does Beiqi see the latest standards, it becomes another key issue. According to the reporter's investigation, on the one hand, according to the previous Saab and BAIC signed a purchase contract, which involved a $25 million co-management fee, it was used to pay for Saab engineers from Sweden to provide technical support to BAIC. These are familiar with GM standards, especially New Saab 9 The Swedish engineer of the chassis, electrical and bodywork of the -5 will help Beiqi to understand Saab's old model of 9-5 R&D, and at the same time, he will also put forward suggestions for improvement.
On the other hand, when BAIC purchased Saab technology, it also bought some common standards. The introduction of talents familiar with common standards is also very important. At present, Beiqi's own brand R&D team headed by Gu Lei, President of Beijing Automotive Research Institute, has planned four vehicle platforms on the Saab platform that were acquired, namely C50, C60, C70 and C80, and C70. The number of engineers is nearly 100, and 70% of them are taking care of the C60 project at the same time.
Nevertheless, many people in the industry still said that although domestic auto companies have purchased foreign technologies and platforms, they cannot buy know-how. "The word know-how is not a drink or a bowl. It is actually a kind of ability. This ability does not actually learn to be reflected in your product. I think we have made this car in such a short time. The best explanation."
Saab becomes inconsequential and obviously changes in the subversive nature of the body, accompanied by great difficulties, first of all security, the other is a variety of parts.
How does Saab, a niche, satisfy Beiqi’s need to open the Chinese mass market independently? This is the biggest challenge for the Beiqi R&D team.
The design bears the brunt. “We only retained the lower body of the Saab 9-5 and redesigned the upper body again. For the Saab 9-5, this change was overwhelming. We spent a lot of effort and the entire upper body was new. And the entire strength and stiffness index we are in accordance with the latest, is to ensure the five-star, side impact on at least four stars." An engineer responsible for the Saab body told reporters that the side of the door is a luxury design fifteen years ago, Saab 9 The body shape of the -5 is out of date, and the redesigned C70G makes the side circumference come in. The door is inside and the shape is more dynamic.
Obviously, the subversive changes in the car body are accompanied by great difficulties. The first is safety, and the other is the reconfiguration of various parts such as side curtains, interior panels, and seat belt detectors.
Code C70G: The Beiqi Saab countdown "is equivalent to completely re-doing. Another is to make structural adjustments. For example, after improving the stiffness, in order to meet the increase in stiffness can be stamped out, you have to make some necessary adjustments. Said the original installation point is here, now we must adjust to other places, or stamping time can not be washed out." The above engineer told reporters.
The change of appearance in order to meet the taste of the public, and the reservation of the entire chassis and powertrain is the established goal of the R & D team. “Saab is known as a land vehicle. The entire chassis is fully retained. Suspensions, powertrains, gearboxes, and front and rear axles have not changed. It is also possible to use Saab’s original suppliers’ products in domestic joint ventures. It is original and at the same time reduces costs."
At the same time, the powertrain of the Saab 9-5 was introduced as it was, but the electronic control system was changed because Saab's original EFI control system was old. Beiqi's newest model was Delphi's latest EFI. Control System. The entire sensor and EFI control system have been changed. In other words, no matter if the engine's fuel consumption, there is a relatively large increase in emissions.
"The Saab 9-5 has a drag coefficient of 0.30, and the improved C70G has a drag coefficient of 0.28. That is, if the entire chassis and power system reach Saab's performance and reliability, the latter may run faster than Saab. "The above engineers finally said.
