On May 18, 2016, Suzuki announced that it had adopted a method that was inconsistent with national regulations in tests conducted to obtain fuel efficiency and exhaust gas data. The company reported the matter to the Ministry of Land, Infrastructure, Transport and Tourism on the same day. Vehicles using the non-compliance test method cover all 16 models currently sold, totaling 2.1 million. Large scrubbers are suitable for cleaning and maintenance of urban streets, as well as cleaning in other industries.

“(We are here to report to you) the results of the survey conducted in accordance with the instructions of the Ministry of Land, Infrastructure, Transport and Tourism. The driving resistance we submitted is calculated by the rolling resistance of the tire and the measured air resistance obtained by the wind tunnel test equipment. We apologize for the test according to the prescribed method," said Suzuki’s chairman Suzuki’s apology at the press conference held on the same day.
On Mitsubishi Motors' fuel efficiency fraud issue, the Japanese Ministry of Land, Infrastructure, Transport and Tourism asked other automakers on April 20 to confirm the existence of the same fraudulent behavior and submit a report. The deadline for submission is May 18, and Suzuki reported that it used a non-compliant test method when calculating driving resistance.
Suzuki confirmed the test of driving resistance for all 16 models currently sold, such as "Wagon R", "Hustler" and "Solio". As a result, it was found that the driving resistance data submitted to the Ministry of International Trade was not the actual measured value obtained according to the “sliding method†stipulated in the Vehicle Law.
Instead, the rolling resistance of the tire, the brake, the gearbox, and the like, and the measured values ​​of the air resistance obtained by the wind tunnel test equipment are accumulated, and the calculated running resistance is calculated. This kind of behavior "started around 2010" (Suzuki Vice President and Technical Director Honda Governance).
Suzuki said that one reason for using the inappropriate method to calculate driving resistance is the geographical condition of the Xiangliang test site in Makinohara, Shizuoka Prefecture. The president of the company, Suzuki Suzuki, said, "The Xiangliang test site is close to the sea and is located on the hill. It is affected by the airflow. The test will be affected by the weather and it will be very difficult to implement."
The taxiing method refers to a time when the vehicle reaches a certain vehicle speed and then switches to inertial running, and detects the time (sliding time) at which the vehicle decelerates to a specified speed at intervals of 10 km/h. There are 8 specified speeds for detecting taxi time (90km/h, 80km/h, 70km/h, 60km/h, 50km/h, 40km/h, 30km/h, 20km/h). For example, when the specified speed is 90km / h, it is necessary to detect the time from 95km / h to 85km / h.
The measurement method of the taxi time is to detect 3 round trips for each specified speed, for a total of 6 times or more, and then take an average value. As valid data for calculating the average value, the error of the maximum and minimum values ​​of the six taxi times should be within 10%.
Therefore, data with an error of more than 10% is invalid and must be retested. For this, Suzuki Junhong said at the press conference: "In order to obtain (effective) data, many tests must be repeated."
The glide method also specifies the wind speed for an effective test environment. The horizontal wind speed of the vehicle driving direction must be less than 5m per second, and the vertical wind speed must be less than 2m per second, otherwise the test data is invalid. Honda said that because the test road is easily affected by airflow, it is difficult to obtain stable data in nature, and it takes a lot of work.
As a countermeasure for the future, President Suzuki Junhiro said: "The windshield wall of the test site will be maintained, the number of test equipment will be increased, and the road surface will be maintained. The driving environment will be improved, and the measured value will be obtained according to the sliding method to calculate the running resistance."
This time, Suzuki made the same mistake as Mitsubishi Motors in detecting the driving resistance without using the sliding method prescribed by the state. However, Suzuki stressed that "(we) judged that there is no intention to intentionally whitewash the fuel. The motivation is to improve the efficiency of the work and obtain accurate data" (Honda).
After detecting this inappropriate behavior of handling the driving resistance, Suzuki once again studied the relationship between the data at the time of application and the measured value obtained by the sliding method. After the instructions were issued on April 20th by the Ministry of International Trade, all of the 16 models being sold were retested in just one month.
The chairman of Suzuki said that the fuel efficiency recalculated using the sliding method is basically "no difference from the catalog value". Therefore, “there is no loss to the customer. We will continue to sellâ€.
Eight of the 16 models involved in the non-compliance test are “ALTO†(listed in December 2014), “ALTO Lapin†(listed in June 2015), “Wagon R†(September 2012) Listing), "Hustler" (listed in January 2014), "Spacia" (listed in March 2013), "Every" (listed in February 2015), "Carry" (listed in September 2013) and "Jimny" (In 2010, the JC08 mode was adopted).
The other 8 ordinary passenger cars are "Solio" (listed in August 2015), "Ignis" (listed in February 2016), "Baleno" (listed in March 2016), "SX4 S-CROSS" (2015) Listed in February), "Swift" (listed in September 2010), "Escudo 2.4" (JC08 model in 2012), "Escudo" (listed in October 2015) and "Jimny Sierra" (2010) The year adopts JC08 mode).
Suzuki also explained to the Ministry of International Affairs that “the fuel efficiency is basically the same as the application valueâ€. However, the provincial staff said that there is no data to confirm that Suzuki’s report is true. Therefore, “(Guojiao) has requested Suzuki to submit supporting data and more in-depth explanations before May 31, 2016â€.
In addition, Suzuki also said that this time the problem is limited to vehicles for the Japanese market. Chairman Suzuki said: "(Suzuki) complies with local laws. For example, India has witness tests and there will be no problems. In the European market, it is also following the rules to conduct business. There is no problem overseas."
