Automotive News reports that Mercedes-Benz will delay the U.S. launch of the diesel version of its C-class sedan by at least 12 months.

Originally scheduled to be available during the first quarter of 2016, Mercedes spokesman Rob Moran says that the C300d will now go on sale “sometime in 2017 (mid-2017 is a reasonable estimate, not firm), but this is certainly subject to change.”

Those hoping for a diesel-powered GLC will also have to wait, as Mercedes indicated that the crossover release will not be happening in 2016.

While manufacturers have pushed back launches of diesel models as a result Volkswagen’s emissions scandal, Mercedes-Benz USA CEO Dietmar Exler says that the company expected diesel versions of its vehicles to trail by up to year given the marques recent lineup overhaul.

Mercedes says its diesel-equipped offerings make up roughly 1.2 percent of U.S. sales.
