Suzuki Motor says more cars given improper fuel economy tests

Suzuki Motor Corp. said Tuesday it had used an improper fuel economy testing method on more models than it previously disclosed, the latest revelation in a scandal that has rocked the Japanese car industry.

The firm said it used a testing method that was not approved by Japanese regulators on 26 models, having previously said 16 were affected, but maintained it had no intention of inflating mileage, The Wall Street Journal reports.

Results from tests using an approved method to measure the resistance a car faces from tires and air showed no significant difference in fuel economy, Suzuki said.

Japan’s transportation ministry had asked the company to submit a detailed report on the issue by Tuesday.

Suzuki had said previously that about 2.1 million vehicles sold in Japan were affected.

On Tuesday it updated that figure to 2.14 million vehicles sold in the country.

Suzuki said that after further probing, it found that the correct testing method was used in three of the 16 models it previously mentioned, while an inappropriate testing method was used in one additional model.

It said 12 other models supplied to other carmakers also used an inappropriate testing method.

However, Suzuki said results from testing all models using the correct method showed better fuel economy than what it listed in its catalogs.
