Suzuki Admits to Using Improper Fuel Economy Testing Methods

- 16 Suzuki cars were tested using improper methods for fuel efficiency
- New tests have shown no change in data or manipulation of fuel efficiency
- The issue doesn't apply to products sold under Suzuki badge outside Japan
This information comes right After Mitsubishi admitted that it had falsified fuel economy data for its vehicles, the Japanese Transport Ministry had ordered all of the country's car makers to present their compliance with government testing methods. This is when the Suzuki opened up about using unauthorised methods to test fuel efficiency. Apparently during the initial tests, instead of submitting the measured data of the car through the coasting test, it provided a build-up of measured data obtained from individual components during rolling resistance tests and air resistance tests in the wind tunnel.
Talking about the cause of the issue the company said in a statement that they consider the background lies in the fact that Sagara proving ground owned by us locates on top on a hill close to sea, where it is significantly affected by weather conditions such as influence of wind and carrying out tests were difficult. However, it has been pointed out by the company that it did not deliberately manipulate the test results and has carried out new tests to check discrepancies in the results. Although there were some minor differences in data, Suzuki believes it's small and it should not pose a significant problem. Also the company claims that no Suzuki-branded cars sold overseas are affected by this problem.

Commenting on this issue a company spokesperson from Maruti Suzuki India said, "The issues do not apply to products sold under Suzuki badge outside Japan. The system of conducting vehicle mileage tests in India is distinct from the one in Japan. In India, all vehicles are tested for road load and emissions by Government approved agencies like ARAI, ICAT and VRDE. As part of the emissions test, these agencies report fuel efficiency of vehicles as well. Based on these reports, Maruti Suzuki voluntarily declares fuel efficiency of its vehicles."
