When news of Volkswagen's use of illegal "defeat device" software in its TDI diesel cars broke back in September, it was assumed the ensuing scandal would negatively impact diesel sales.

The public's trust in diesel was obviously shaken, and Volkswagen's cessation of diesel sales removed a large number of models from the equation.

And sure enough, sales of diesel passenger cars in the U.S. have taken a dive, although diesel trucks and SUVs are faring slightly better.

Just 222 diesel cars were sold in the U.S. in January, according to sales data from WardsAuto cited by ExtremeTech.

That's out of 1.15 million total U.S. new-car sales during the same month.

Diesel SUV sales weren't quite as dismal, with 1,300 recorded for the month of January.

And--thanks mainly to sales of vehicles for work use--diesel light-duty truck sales stood at 22,000 for January. That's still about 4,000 fewer sales compared to January 2015.

A year ago, Volkswagen alone sold 3,500 diesel vehicles, while Audi sold 800.

Before news of the company's emissions cheating broke, diesels typically accounted for about 25 percent of Volkswagen's monthly sales.

Without diesel models from VW, Audi, and Porsche on sale, the bestselling diesel car in the U.S. for January 2016 was the BMW 328d.

Available as either a sedan or wagon, the diesel 3 Series recorded just 69 sales.

In addition to the 328d, BMW continues to offer diesel versions of its X3 and X5 SUVs, and a handful of other carmakers continue to offer diesels as well.

Land Rover offers its own 3.0-liter diesel V-6 in the Range Rover and Range Rover Sport.

And General Motors recently launched diesel versions of its Chevrolet Colorado and GMC Canyon mid-size pickup trucks. It also plans to revive the diesel engine option in the Chevy Cruze compact at a later date.

Meanwhile, there is no indication that 2016 Audi, Porsche, or Volkswagen diesel models will be certified for sale by the U.S. Environmental Protection Agency anytime soon.
