［SUZHOU, June 30, 2018］The first QIANTU production model—the QIANTU K50—has rolled off the production line in Suzhou, delivering the promise of a “high-quality car” and marking its official establishment of a complete car manufacturing system that integrates electric car design, R&D, production and supply chain. With its bold exploration in new materials and new processes, QIANTU is injecting new energy into the innovation-driven development of China’s automobile industry and equipment manufacturing industry.
“The completion of the production model marks a milestone in the development of the QIANTU brand,” said Lu Qun, Chairman of Qiantu Motor. “Several weeks later, the QIANTU K50 will officially hit the market to stand the test from customers. For QIANTU, it is just the beginning of a long journey. We will stay driven by technology, quality and performance to provide consumers with clearly superior experiences and win them over. Qiantu Motor is committed to making high-quality pure electric cars that are a pleasure to drive and advance the industry’s development in a unique way.”
Delivering the promise of a “high-quality car”
To make a high-quality car, there is a set of strict procedures and rules. From the manufacturing of QIANTU’s first prototype in 2014, to comprehensive tests and trials, including a small-scale trial production, to obtaining manufacturing approval after a rigorous regulatory review, Qiantu Motor has delivered its promise to build a “high-quality car” through persistent actions.
Distinctive design language was applied to the QIANTU K50, giving it the visual of a shark cruising in the city. Its body is comprised of an all-aluminum frame and carbon-fiber covered parts, all of which incorporate new composite materials. Powered by a front and rear dual electric motor based all-wheel drive system that have a maximum power output of 320kW, it can accelerate from standstill to 100km/h in just 4.6 seconds and has a top speed of 200km/h. The model’s double wishbone front and rear suspension, dual stabilizer structure, and chassis calibrated by British vehicle-testing company Mira, all provide superb handling, superior comfort, and excellent stability. In addition, it is equipped with a full range of performance and tuning packages such as Brembo 4-piston brake calipers, 19-inch forged aluminum wheels and a Bosch ESP System to provide users with superlative driving pleasure.
Establishing a complete car manufacturing system
Car manufacturing is a highly systematic form of engineering, requiring vast experience and well-established practices. Knowing and mastering the foundation technologies is the key to reaching the highest-level of car manufacturing.
From the very beginning, Qiantu Motor has been committed to independently establishing a complete NEV manufacturing system. It has worked its way up from foundation technologies, accumulating the right practices step by step and promoting product iteration while driving the industry’s innovation-driven development. Their extensive experience has resulted in QIANTU K50, an achievement that benefits from a well-developed car manufacturing system.
Through unwavering effort, Qiantu Motor has independently mastered three core technologies: vehicle control unit (VCU), rechargeable energy storage system (RESS) and lightweight construction to deliver a vehicle with unprecedented electric driving pleasure. As of June 20, it had filed 1,190 patent applications, of which 415 had been granted.
Qiantu Motor is responsible for the production quality of the entire manufacturing process and has established its own battery system production line in addition to their car manufacturing plant. Its Suzhou plant houses the first carbon fiber automotive part production line and the first all-aluminum body frame production line in China. At the same time, it has independently constructed its battery system production line. The Suzhou plant complies the strictest environmental standards and is the first car plant to be established in compliance with the Administrative Regulations on Taihu Lake Basin. In addition to zero wastewater discharge, it complies with emissions standards that are more stringent than the national standards as well. In alignment with ‘Industry 4.0’, Qiantu Motor’s Suzhou plant delivers a high level of flexible, automated and individualized production.
Pioneering in the use of new materials and new processes
Lightweight composite materials are a strategic new direction for the automobile industry. Qiantu Motor has pioneered the application of carbon fiber composite materials and aluminum alloy frame in production car manufacturing. It has steadily refined its processes to achieve precise and mature systems, driving the transformation of China’s car manufacturing industry while leading the innovation-driven development of its equipment manufacturing industry. By successfully applying carbon fiber materials to car manufacturing on a large scale and overcoming a series of challenges to adopt a high-temperature quick prepreg compression molding process, Qiantu Motor has maximized lightweight construction and greatly increased production efficiency. Qiantu Motor offers the first all-aluminum body frame production line in China’s automobile industry and has not only maximized the lightweight and pliable properties of aluminum alloy, but also solved the welding-induced thermal deformation of aluminum alloy through extensive R&D work.
Built with intensive use of new materials and processes, the QIANTU K50 has 29 carbon fiber parts which combine to weight only 46.7kg, making the model approximately 40% lighter than if made from steel or more than 20% lighter than aluminum alloy. Its all-aluminum body frame weighs just 243 kg, approximately 38% lighter than traditional steel frames. These new materials, processes and technologies will also be used on future production models by Qiantu Motor.
The development of new energy and intelligent technology has brought the automobile industry into a period of unprecedented transformation and also presented a strategic opportunity for China’s automobile industry to accelerate ahead. With “Evolution in Motion” as its brand value, QIANTU is committed to continuously innovating in product, material and process technologies to promote a “positive cycle” for China’s NEV industry and be worthy of this great era in the automobile industry.
