BMW to offer four-cylinder diesels in North Americ

BMW will offer four-cylinder diesel engines in North America as it seeks to improve fuel efficiency and match the performance of its current six-cylinder gasoline engines.

BMW is considering diesels in a range of models, including its 1 series, 3 series and 5 series sedans and possibly the X3 crossover and Z4 roadster, said Tom Baloga, vice president of engineering for BMW of North America.

"You're going to see it in the 3 series, and the 5 series is a good possibility," Baloga said. "If the performance is sufficient in the X3, U.S. customers would likely accept it in the X5 as well."

Baloga did not disclose timing but said BMW will be ready to comply with emissions rules. Federal rules will regulate the amount of carbon dioxide per mile, based on an automaker's fleet average. The rules call for an average of 250 grams of C02 per mile by 2016, which equates to 35.5 mpg.

Baloga said BMW will seek diesel performance comparable to that of its current six-cylinder engines by using a turbocharged 2.0-liter model tuned for performance. In Europe BMW sells a 320d with a 2.0-liter turbocharged diesel.

"Our four-cylinder diesel will be so good that people will readily accept it as a replacement for six cylinders," Baloga said. "With the weight reduction, performance could be similar to the turbocharged six-cylinder [gasoline engine] if we pushed very hard."

Baloga said BMW will aim for a substantial increase in its diesel sales mix in North America.
