 ( ) has announced the addition
 of A global market review of automotive steering systems - trends, companies
 and forecasts to 2010 - 2nd edition to their offering.

     During the last 15 years, there has been a slow evolution in power
 steering but recent engine-independent electro-hydraulic power steering (EHPS)
 and electric power steering systems (EPS) have marked a major change in the
 technology. For many years, power steering technology was focused on hydraulic
 systems but demand is now favouring electric power steering mainly due to
 reduced fuel consumption and logistical benefits.
     Although estimates of future penetration levels by region and worldwide
 vary, there is complete agreement that the trend is upwards. The only
 disagreements concern the slope of the trend and at what level it might
 plateau. Delphi anticipates that worldwide adoption rates of EPS will reach
 20% of the light vehicle market by 2007. European penetration during that
 timeframe could reach as high as 33%, says Delphi. Koyo Seiko also anticipate
 exponential growth for EPS; predicting that it will be fitted to more than 30%
 of new cars built worldwide in 2005, equivalent to 20 million vehicles.
 Looking further ahead, TRW forecast that by 2010, 50% of cars produced
 worldwide will incorporate some form of electrical assistance integrated into
 the steering system.
     The main reasons for strong growth in electric steering, as opposed to
 hydraulic, is that electric systems are more economical to run, lighter,
 recyclable and easier to package and install. Electric and electro-hydraulic
 power steering systems are typically lighter and more compact than
 conventional hydraulic systems. TRWs electrically assisted steering (EAS), for
 example, is a power-assist system that eliminates the connection between the
 engine and steering system. Its migratory product, EPHS (Electrically Powered
 Hydraulic Steering) replaces the customary belts and pulleys with a brushless
 motor that drives a hydraulic power steering pump in a conventional rack and
 pinion steering system. EPS takes EAS technology a step further, eliminating
 hydraulic fluid and the accompanying hardware completely. An EPS module
 includes the motor, torque sensor, electronic control unit (ECU) and
 control/diagnostic software. Although EPHS was initially considered a
 transitionary technology -- preceding the arrival of full EPS systems --
 manufacturers now predict a strong growth path.
     In this second edition reviewing the key market drivers for passenger car
 and light vehicle steering systems, the analysis is broadened from the popular
 1st edition, providing forecasts of six types of steering system:
      - Rack Drive Electric Power Steering
      - Pinion Drive Electric Power Steering
      - Column Drive Electric Power Steering
      - Electrically Powered Hydraulic Steering
      - Power Rack & Pinion Steering
      - 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 75%
 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 forecasts 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 market
 shares for both electrically assisted steering and conventional hydraulic
 steering systems in Europe and North America. All in all, this report will
 give you 50 market volume and value forecasts by region and technology through
     Chapter three sets out 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 60% stake in the
 Mercedes-Benz Lenkungen steering system subsidiary from DaimlerChrysler,
 adding Euro 300 million a year in sales to its growing Presta steering system
 business. In 2002, 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.
