Is the i-ELOOP technology still being offered on the 2021 Mazda 6's sold in the United States? I know that it had been offered in the 2014/15/16's with the Grand Touring trim and the Technology Package. There are a number of additional trims on the 2017's and newer. All have lower fuel economy and more powerful engines with the higher-end "luxury" trims. Was i-ELOOP discontinued in 2017?
