Chapter 1 Executive summary 

Chapter 1 Executive summary 

Background to the global automotive market 

Car manufacturers are under pressure as never before. On the one hand, 

demand for the car has never been higher with new markets opening up in 

China, South Asia, India, Latin America Russia and Eastern Europe offering 

untold opportunities but on the other, they are having to address the nearuniversal 

worries about climate change, emissions and the worldwide demand 

for fuel. While there is some debate about just how much the internal 

combustion engine contributes to polluting the environment compared to other 

man-made sources, the fact is that they are seen by many governments and 

legislative bodies around the world as one of the prime culprits. 

These are the short- and medium-term issues that the vehicle manufacturers 

are having to address, but there are also some very dark clouds looming on 

the horizon that many of the vehiclemakers are acknowledging, even if they 

are reluctant to talk about them publicly, and that is the threat of diminishing oil 

supply. 

OPEC (the Organization of Petroleum Exporting Countries) has forecast that 

world energy demand will grow an average xxx% per annum between 2005 

and 2030. It expects oil to remain the leading source of energy worldwide 

during this 25-year period, with oil’s share of total world energy demand 

declining slightly from a current xx% to xxxx%. 

Meanwhile, the International Energy Agency has forecast that oil demand will 

rise xxm barrels per day (mb/d) to xxxmb/d by 2030. The US government has 

put that figure at xxxmb/d by that time. 

Much of this demand is being driven by the increase in global vehicle 

production. Over the next quarter-century, it has been estimated that the 

emerging markets are going to drive up vehicle production far beyond anything 

seen to date. By 2030, total annual global production has been forecast to be 

around xxm units with China and India accounting for xxm units and xxm 

units respectively. The projected xxxmb/d or xxxmb/d will simply not meet this 

level of production. Some estimates have put this figure nearer to xxxmb/d as 

the realistic alternative.

Chapter 2 Technical review 

Chapter 2 Technical review 

As described in the Bosch Automotive Handbook, the turbocharger is a 

relatively easy and cheap way of optimising the fuel consumption of the 

internal combustion engine. The principle behind it is relatively simple although 

the technology has become far more sophisticated and complicated over the 

years. 

The principle behind the turbocharger is fairly straightforward. The exhaust 

gas, which is considered lost or wasted energy, is captured and pushed or 

‘blown’ back through the engine by the turbocharger. It therefore has to be 

located somewhere close to the cylinder head which brings with it packaging 

and heat problems. These disadvantages, together with the extra pipework 

required, are generally outweighed by the benefits the device brings. 

As a technology, it is not exactly new. A form of turbocharging – supercharging 

(the principle of which is fresh air being blown under pressure into the cylinder 

head) – has been seen on cars almost since the birth of the car. The most 

well-known of them is perhaps the so-called Blower Bentley that raced at Le 

Mans in the late 1920s. While not an official Bentley modification, the big, 

green racing machine with straps on the bonnet and a large device sticking out 

from underneath the radiator encapsulates for many the vintage Bentley. 

In the 1980s, the turbocharger was very much in fashion as it was the era of 

the turbocharged xxx-litre Formula 1 engines that were able to develop over 

xxxxxbhp at their peak. For manufacturers like Renault and BMW which were 

participating in Formula 1 at the time, it made marketing sense to have 

turbocharged models in their range even if they were not out-and-out 

competition cars. 

Once the turbocharger was banned from Formula 1 in 1989, the technology fell 

from favour, virtually disappearing from the passenger car for a number of 

years, and only making a comeback on the direct-injection diesel engine. 

However, there is a fast-growing trend which is seeing them installed on directinjection 

gasoline engines as they offer xxxxx% improvement in fuel 

consumption figures and around xx% more torque.

Chapter 3 Geographical market analysis by region 

Chapter 3 Geographical market 

analysis by region 

North America 

The North American market is quite unlike that of anywhere else in the world – 

it is the only region where light trucks outsell passenger cars and the dieselpowered 

passenger car market is still extremely small despite the combined 

marketing might and prestige of the German car manufacturers that have been 

pushing the technology. 

It is also a region that is in some difficulty. The economic downturn, the credit 

squeeze, the falling dollar and the high price of fuel by US consumers’ 

standards have all had a major impact on every market, including cars and 

light trucks. The figure of xxxxxm light vehicles sold in 2007 was down xxx% 

from the xxxxxm of a year earlier, and the prospects of it climbing back up look 

remote in the near future. 

As is the norm in the US, light trucks make up a healthy part of the total sales 

mix, accounting for xx% in 2007. Where some other vehicles that comprise 

this sector, namely sport utility vehicles (SUVs), had already experienced a 

downturn, pick-up sales had remained strong but even they are now seeing a 

slowdown. 

Despite this downturn in light-truck sales, though, they are still expected to 

account for xx% of the total market in 2008 and 2009. However, a slightly 

smaller market share of a slightly smaller market could mean the loss of xm 

sales over this two-year period. 

The light-truck market, though, is quite a resilient one and any downturn is 

never expected to last too long as these are working vehicles as much as 

lifestyle ones and so need to be changed on a regular basis. High gasoline 

prices, though, are causing a great deal of pain and as oil is priced in dollars, 

and the dollar is falling against other currencies, the high price of a barrel of oil 

is unlikely to go down in the region.

BorgWarner Turbo & Emissions Systems 

Headquarters: xxxx Hamlin Road, Auburn Hills, MI 48326, US 

Employees: xxxxxx worldwide as of 2007 

Locations: xx facilities in xx countries as of 2007 

Activities: Headquartered at Auburn Hills, Michigan, US, BorgWarner Inc is 

one of the major manufacturers and suppliers of automotive components. The 

company serves a majority of global original equipment manufacturers (OEMs) 

including GM, Ford, Daimler AG, Chrysler, Volkswagen, Renault, BMW and 

Fiat. The company operates through two reportable segments: Engine and 

Drivetrain. The Engine segment manufactures a range of components 

including turbochargers, thermal and emissions systems, chains and timing 

systems. The Drivetrain segment manufactures transmission components and 

torque management products. 

2007 sales (BorgWarner): US$xxxxxbn combined worldwide 

2007 net earnings (Borg Warner): US$xxxm 

The worldwide market for turbochargers in 2007 was xxxxxxxxxx units of which 

BorgWarner accounts for xxxxxxxxx or xx% market share. It also has a xx% 

market share in the burgeoning gasoline turbocharger market. 

BorgWarner Turbo Systems’ turbocharger business accounts for much of the 

group’s growth over the past several years, particularly in the European 

market. However, there are strong indications that the markets for both turbodiesel 

and turbocharged gasoline technology will grow in the rest of the world, 

including the US, strongly contributing strongly to the group’s overall growth. 

While its variable turbine geometry (VTG) is creating a great deal of interest 

from its customers around the world, it is the Regulated 2-Stage (R2S) 

turbocharger technology and gasoline turbochargers that are the most 

important for the company. 

BorgWarner Turbo & Emissions group also has a facility in Chennai to serve 

the engineering, technology, and manufacturing needs of its Indian customers. 

SeohanWarner Turbo Systems, a BorgWarner joint venture, has also opened 

a production plant in Korea in 2008 which is scheduled to produce up to xm

Chapter 5 Other suppliers 

Bosch Mahle Turbo Systems 

In April 2008, Bosch and Mahle established Bosch Mahle Turbo Systems, a 

50/50 joint venture headquartered in Stuttgart, Germany to manufacture and 

market exhaust gas turbochargers. The joint venture partners plan to work 

together to develop and manufacture turbochargers for gasoline and diesel 

engines, and to market them worldwide. Series production is planned to start 

in 2010. 

The JV will allow Bosch to offer its advanced injection technologies and Mahle 

its know-how on the development and manufacture of high temperatureresistant 

turbocharger components. In addition, Mahle Powertrain specialises 

in the development, design, and application of turbocharged engines. Both 

partners in the new joint venture can therefore draw on extensive enginesystems 

experience as well as competence in large-scale series production of 

ultra-precision components in and around the engine. 

“This joint venture will now allow us to offer our customers from a single source 

a complete product portfolio for reducing fuel consumption and emissions,” 

said Dr-Ing Bernd Bohr, chairman of the Bosch Automotive Group. Prof Dr 

Heinz Junker, chairman of the Management Board and CEO of the Mahle 

Group, added: “With their systems and components know-how, Mahle and 

Bosch complement each other ideally as partners for the development of new 

exhaust gas turbochargers. Moreover, the two companies are names to be 

reckoned within the automotive powertrain field.” 

Turbodyne Technologies 

Turbodyne Technologies is a developer of patented electrically assisted aircharging 

technology that enhances the performance of internal combustion 

engines. Its product, the TurboPac, is commonly referred to as an electric 

turbocharger or electric supercharger with applications for small-displacement
