VW to make new Golf lighter by 100kg with use of stronger steel

Article by Anita Panait, on August 23, 2012

Volkswagen will reduce the weight of its seventh-generation Golf by as much as 100 kilograms (220 pounds) through the use of stronger steel to minimize the metal content. The weight reduction is expected to translate into a 23 percent reduction in fuel consumption. According to the carmaker, the new materials and production processes, which is part of the Volkswagen Group's new MQB modular manufacturing system, will also be used by over 40 small and mid-sized models, or around 3.5 million cars vehicles.

VW expects the shared MQB platform to shave production costs by 20 percent, manufacturing time by 30 percent and one-time expenses by 20 percent.

Savings gained from using the platform will be used to fund upgrades of in-car entertainment systems and the development of new generations of VW vehicles, says Autonews.

VW is set to unveil the revised version of its flagship Golf compact on September 4, 2012, as part of its effort to gain market share and overtake Toyota Motor Corp. and General Motors Co. to become world best-selling carmaker by 2018.

According to Ulrich Hackenberg, VW’s brand development chief, the Golf plays a distinguished role at the carmaker because of its high production volumes, the number of employees behind it, and because it is the “face of VW."

Volkswagen's manufacturing strategy entails using strengthened steel to cut overall weight, since it is a cheaper alternative to materials such as aluminum or carbon fiber.

The new and lighter Golf is expected to emit 13.9 percent less Carbon Dioxide per car, equal to about 119,000 metric tons in European markets, complying with tougher environmental rules.

Almost four decades after Volkswagen’s original model transformed the petite family car, the cutting-edge Volkswagen Golf has been released in Berlin. The VW Golf is the seventh generation of its class. It builds upon the feat of its forerunners—over 29 million of which were sold over the years. The success of VW Golf’s predecessors brings comfort, efficiency, practicality and safety to the class in new heights.

Although it offers more space for passengers and more sophisticated technological features more than ever, state-of-the-art manufacturing techniques play a part in making the VW Golf Mk VII up to 100 kg more lightweight than the car it supersedes. This development in the system makes the model up to 23 per cent more efficient.

To sum it all up, the latest Golf has a more powerful stance and a whole raft of basic and optional active and passive protection systems which make it safer than before. The latest Volkswagen Golf is made on the Modular Transverse Matrix or what is usually called as the MQB (Modularer Querbaukasten) platform. This standardizes a lot of car component parameters through other auto classes and brands and permits access to brand new innovations and powertrains, like modern technology in infotainment and vehicle safety, which until today were made exclusively for cars in the luxury sector.

Its length is 4,255 mm, and because of that, the latest Volkswagen Golf is 56 mm longer than its older brother, with an extended wheelbase of 2,637 mm-- 59mm longer than the former. The wheels at the front are extended by 43 mm, aiding to create more interior room, while this model is 13 mm broader as well, at 1,799 mm, and 28 mm shorter, at 1,452 mm. This aids to produce 10 percent enhancement in the drag co-efficient, which is currently at 0.27 Cd.
