Chapter 1 Introduction Page 4 ○ ○ ○ ○ Column Drive Electric Power Steering; Electrically Powered Hydraulic Steering; Power Rack & Pinion Steering; and Recirculating Ball Systems. Although power rack and pinion steering systems look set to dominate the global vehicle market for some years to come - currently accounting for xx% of the global market - demand is gradually switching to electric power steering mainly due to fuel consumption and logistical benefits. Consequently, the main focus of this forward-looking report is on the current market and outlook for electrically-assisted steering systems. Chapter two sets out our forecast for product trends, fitment levels and market wholesale values for all six types of steering in Western Europe, North America, Asia-Pacific and worldwide through 2008. It also identifies some market shares for both electrically assisted steering and conventional hydraulic steering systems in Europe and North America. All in all, this report provides no less than 50 market volume and value forecasts by region and technology through 2008. Chapter three sets out some recent innovations and the forces driving those technical advances. The likelihood of a future dominated by electric steering systems is prompting some market participants to strengthen their presence in the market, investing in new plant and equipment and forming new joint ventures. For example, ThyssenKrupp recently acquired a xx% stake in the Mercedes-Benz Lenkungen steering system subsidiary from DaimlerChrysler, adding €xxx million a year in sales to its growing Presta steering system business. In 20xx, Toyota and three of its partners have formed a new joint-venture, called Favess, to develop, manufacture and sell drive-by-wire electric power steering systems. Chapter four provides profiles of the major steering system manufacturers, including Delphi, NSK, ThyssenKrupp, Toyoda Machine Works, TRW, Visteon, and ZF Lenksysteme. © 2004 All content copyright Aroq Ltd.

Chapter 2 The market Page 5 Chapter 2 The market Market trends During the last decade or so there has been a slow evolution in power steering but recent engine-independent EHPS and EPS have marked a major change in the technology. While EPS and EHPS have made inroads in Europe and Japan, American vehicle makers have been reluctant to replace their proven hydraulic systems with the more costly electric ones because they claim the benefits are largely unnoticeable and the added cost unjustifiable to customers. EPS systems began to appear in the late 1980s, initially in mini cars. The key benefit of EPS is in the increased fuel efficiency obtained by freeing the engine from powering the steering compressor, and demand would probably be far higher if fuel prices in the US and Japan were as high as they are in the UK and Germany, for example, where the fuel savings of EPS have sufficient impact to offset the added cost of the system. With regard to power steering, there has been a transition from hydraulic to more environmentally-friendly electronic control systems, (hydraulic power steering involves excess pumping, whereas electric power steering uses less energy and is also lighter and more compact). The diffusion of electric power steering is led by Europe, with its strict environmental regulations, as well as by Japan, where small cars are common. Electrically power-assisted steering systems are headed for the mass-market worldwide, helped by their potential to save manufacturers money, reduce customers’ fuel bills, save designers valuable space, and possibly save lives as well. TRW believes switching to electric can save vehicle makers $5-10 per car, because the units are quicker to install, eliminate complex set-up engineering and have fewer moving parts. TRW’s EPHS module is fully filled with hydraulic fluid and takes GM about 30 seconds to install and connect the module to the vehicle’s electrical system. Delphi estimates its own system cuts four minutes off the assembly time of a vehicle and reduces component parts stocked from 15 to only two. Delphi also believes that its system can deliver fuel savings of 0.21 to 0.41 kilometres per 100km, because it draws less power from the engine. Electric steering could also be safer, as it still works if the engine stalls, unlike hydraulic systems. © 2004 All content copyright Aroq Ltd. All rights reserved.
