Over 1.2 billion vehicles are on the world's roads today, and more than 95 percent of those are 'light duty vehicles' which includes passenger cars, trucks and commercial vehicles weighing up to 10,000 lbs. Of these vehicles, more than 96 percent are run by conventional internal combustion engines powered by either gasoline or diesel...

Less than half of the vehicles in use by 2035 will be driven by internal combustion engines, say the experts at Navigant Research, based in Boulder,CO. "Automakers, governments and motorists are all becoming increasingly concerned with fuel economy," says Scott Shepherd, research analyst with Navigant.  "As a result, the auto industry is transforming rapidly.  Engine downsizing and drivetrain electrification  through stop-start and hybrid technologies will become the LDV standards by 2020."
Navigant Research estimates nearly 84.1 million new LDVs will be sold globally in 2014.  The increased adoption of drivetrain electrification and alternative fuels will have considerable impacts on the markets for LDVs, fuel infrastructure development, and energy demand.  Utilities will be particularly affected by increased interest in plug-in electric vehicles (PEVs) and natural gas vehicles (NGVs).

Among the fastest-growing alternative drivetrain technologies is stop-start, which eliminates idling by switching off the engine while the car is not moving.  Sales of LDVs with stop-start capability will reach 48.6 million annually by 2020, according to the report, representing nearly half of the overall LDV market.

 The report, “Transportation Forecast: Light Duty Vehicles”, analyzes the global LDV market in seven segments: stop-start vehicles (SSVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs), natural gas vehicles (NGVs), fuel cell vehicles (FCVs), and conventional ICE vehicles.  Forecasts for the segments fueled by petroleum derivatives (SSVs, HEVs, PHEVs, and ICE vehicles) are broken out by fuel (as well as by region): gasoline or diesel.  

Global market forecasts for sales and the number of vehicles in use, segmented by country, drivetrain, and primary fuel, extend through 2035.  An Executive Summary of the report is available for free download at www.navigantresearch.com.
