BERLIN -- Volkswagen manipulated the carbon dioxide emission levels of more gas-powered vehicles than previously disclosed, a spokesman for the carmaker said on Monday.
VW said on Nov. 3 it had understated the level of CO2 emissions in about 800,000 cars sold mainly in Europe, and consequently misstated their fuel usage. It said then that the cheating affected predominantly 1.2 and 1.4 liter diesel engines and one petrol engine, the 1.4 liter motor with a cylinder cut-off.
In a statement published on Friday after European business hours, the carmaker said it had also identified "implausible CO2 levels" in current gas models, including the 1.0 liter Seat Ibiza, the 1.2 liter VW Jetta and the 2.0 liter VW Passat. Some 24 models with petrol engines out of a total 130 VW group vehicles were listed in the attachment on Friday.
A VW spokesman confirmed on Monday more petrol engines were implicated by the CO2 malfeasance than previously disclosed.
The revelations about fuel economy and CO2 emissions have deepened the crisis at VW, which is expecting costs of at least 2 billion euros ($2.1 billion) linked to these issues.
The scandal initially centered on software used on up to 11 million diesel vehicles worldwide that VW admitted in September had vastly understated their actual emissions of pollutant nitrogen oxide. VW has set aside 6.7 billion euros ($7.16 billion) to help cover costs related to the vehicle recalls.
