Default Why did Honda kill its best performance engine?

The performance profile of the turbo four may have doomed it to being merely a footnote in Honda's illustrious history.

When the 2013 Acura RDX launches this spring, Honda will quietly close down a spur line of its Anna, OH, plant. Since 2006, it had been building the 2.3-liter four-cylinder engine used in the first-generation RDX there. These engines were unique, the company's first to be fitted with a turbocharger from the factory. But the redesigned 2013 RDX will be available only with a V6, and with no other application for the turbo four, Honda's most impressive performance engine will die an ignoble death.

The 2.3-liter turbo was a variation of the 2.4-liter four used in the Honda Accord and the Acura TSX. Rated at 240 horsepower, it was the 260 lb-ft of torque that made things special. Honda's traditional approach to engine design had favored high-revving, small displacement engines that made generous power thanks to variable valve timing technologies - but at the expense of torque output. So when Honda announced that it would be producing a turbocharged engine for the first time, it seemed to herald the next wave of Honda performance. Finally, some torque to match the howling VTEC power. But sadly, it was the performance profile of the turbo four that may have doomed it to being merely a footnote in Honda's illustrious history.Continue reading Why did Honda kill its best performance engine?
