In the last ten years, diesel engines have made giant steps forward, particularly in Europe. NOx emissions have reduced five-fold and particulate emissions have reduced from 25 mg/km to 4.5 mg/km. In 2015, diesel features twin turbocharging systems, electric superchargers, complex exhaust gas recirculation and ultra-high injection pressure, offering consumers pulling power and astonishing emissions performance while still retaining their excellent fuel economy.

But all this comes at a cost. The key challenge for OEMs and suppliers alike is implementing these new technologies in diesel engines so they retain their performance and economy advantage while remaining compliant with ever tighter regulations, all without adding too much cost to the car. A serious challenge, but one that is being met with optimism: diesel is set to remain a large factor in Europe, and is breaking into new markets in North America and Asia.

“The combustion engine has the advantage of decades of development. Such a technology does not simply become obsolete from one day to the next. On the contrary; we will see potential to further improve diesel and gasoline engines. I believe that a 15% efficiency improvement is possible by 2020” – Prof. Rupert Stadler, Chairman of Audi’s Board of Management

“Diesel Engines: Trends, Technologies and Future” is a comprehensive overview and forecast of technical, commercial and future developments in passenger car diesel engines. The report is an essential guide for managers looking to understand the current and future state and market potential of diesel engine technology and the use of diesel engines in passenger cars.

Report Coverage

- Chapter 1 looks at the market trends and drivers currently affecting diesel technology, in particular fuel technology, economy, emissions, environmental demands, and customer behaviour.
- Chapter 2 examines the regional situation around the world: prospects, taxations, trends and differences,
- Chapter 3 takes a look at the OEM strategies – how do the different OEMs approach and brand diesel, and how to they address customer needs?
- Chapter 4 looks in detail at the latest technological trends and issues – turbocharging trends, injection systems, mateirals, airflow management, stop/start, diesel hybrids, etc.
- Chapter 5 details the leading diesel suppliers and what makes them what they are today – Bosch, Continental, Delphi, Denso
- Chapter 6 forecasts diesel sales around the world by region to 2020
- Chapter 7 profiles the leading 16 suppliers in the sector

The report answers questions such as:

- Where is the growth potential? Asia, America, or both?
- Will Europe start to stagnate as a diesel region?
- What are the OEM trends? Will diesel continue to be interesting for performance brands?
- Diesel engines are cleaner than ever, but can they keep up with ever tightening emissions regulations?
- Suppliers and strategies – European companies lead the way, but will they stay ahead?
- Where is future demand coming from, and what will it look like?
