Suzuki on Wednesday said it has found "discrepancies" in its fuel-economy and emissions testing, but denied that it cheated to make its cars seem more efficient than they were.

"Any wrongdoing, such as manipulation of fuel efficiency data, were not found," it said in a statement.

"Some discrepancies were found in the automobile emission and fuel-efficiency testing process" between the testing method required by the government and what Suzuki did, the statement added.
