Market Share for Variable Geometry Turbochargers
In recent years the market share of variable geometry turbochargers has been increasing steadily due to the trends of engine downsizing driving development in the field. For more information on these factors which motivate the development of turbocharging technology, see here.
It can be very difficult to find reliable market data without paying thousands of pounds for marketing reports from professional marketing companies. However for the purpose of illustration some data can be obtained freely to describe how variable geometry devices have been taking control of the turbocharging market. The chart below plots the advance of VGT (Also known as VNT, Variable Nozzle Turbocharger) from the early 1990's up until 2010. It can be clearly seen that VNT (VGT) technology makes up a vast section of the diesel market, but only 10% of the gasoline market. This is down to challenges associated with applying variable geometry turbo technology to the high temperature exhaust gases present in gasoline engines, which can be up to 1050 degrees Celsius.

Market Breakdown for Turbochargers and Variable Geometry
Marketing reports can be few and far between for technical areas such as turbocharging, and those that are readily available cost a small fortune, at the time of writing the only readily available reports to individuals will set you back around $2500-5000 for a single user license.
With that in mind we have gathered together as much information as possible from other available sources here in this article, some key references are listed at the bottom of the page.
First and foremost, turbocharging as in industry is on the rise. Global trends in engine downsizing for efficiency gains and reduced emissions are driving the demand for smaller engines, which in turn require turbocharging in order to maintain performance levels. There are a number of options for engine manufacturers to chose from at varying cost, with fixed geometry turbines the simplest and cheapest solution.
Fixed geometry turbochargers have the infamous of problem of slow spooling up, and lack of performance at low RPM ranges. Turbo lag is a commonly used phrase to describe the sensation of very poor transient response from a turbocharger at low engine speeds. A solution to this problem is variable geometry turbocharging (VGT).
The main companies in the Turbocharging and VGT markets are shown in the market breakdown below for various applications:
