Speaking with The Detroit News, Mark Trahan from Volkswagen US said that the carmaker will replace its remaining naturally-aspirated engines with turbocharged units as the brand's models are refreshed.
“You have to have a turbo these days,” Mr Trahan said.
“We only have one normally aspirated gas engine, and when we go to the next generation vehicles that it’s in, it will be replaced. So three, four years maximum.”
Trahan's comments reflect the general direction of the industry, and echo comments from Ford vice-president Joe Bakaj earlier this week, saying that ‘conventional’ engines will soon disappear from Ford’s line-up.
While the US will be turbo-only soon for Volkswagen, it’s unclear what the carmaker’s plans are for the rest of the world, including Australia.
One key difference between the US market and Australia is the sub-light Up hatch, which is currently equipped with a frugal 1.0 litre three-cylinder engine.
