The rate at which older combustion-engined cars are removed from the world’s roads will have to speed-up if air quality around the globe is to be tackled rapidly, the world’s car engineers believe.
“Ultimately the speed at which we can changeover the fleet is the constraint on cleaning up air and I think we need a forcing function for us as an industry to work around,” said Paul Mascarenas, a board director of FISITA, which represents 200,000 global automotive engineers.
Mascarenas, a former senior Ford Europe engineer, believes that even if battery electric vehicles were available in multiple model ranges and in free supply today, it would still take 10 to 15 years to substantially replace the world’s fleet of combustion-engined cars with cleaner alternatives.
“There will be various constraints, including new car supply, and supply chain, but it is not clear when or how those constraints will be taken off,” said Mascarenas.
“It is undetermined the time to change over the fleet, to get to one or 1.5 billion alternative fuel vehicles in service globally by 2040,” he said.
European governments are aligned around banning the sale of solely combustion-engined new cars by 2040, with many setting targets for a reduced percentage by 2030.
The UK government, for example, wants new cars sales to be “50 to 75 per cent electrified” by 2030 and is working on a definition of electrified, likely to hinge on an electric-only range of 60 miles.
FISITA chief executive Chris Mason describes the switchover as a “significant challenge”, but believes it will be substantially pushed by "societal acceptance and demand" rather than “leverage" by politicians.
