DaimlerChrysler’s Freightliner Corp. subsidiary will continue using Cummins engines for diesel motorhome chassis despite DaimlerChrysler’s plan to acquire Detroit Diesel, according to Freightliner spokeswoman Debi Nicholson.

“Detroit Diesel doesn’t make an engine in that (motorhome engine) size,” Nicholson said.

DaimlerChrysler announced in July that it intends to buy the 78.7% of Detroit Diesel that it does not already own. The acquisition is expected to be completed this fall.

The acquisition of Detroit Diesel would make DaimlerChrysler “the world’s largest manufacturer of diesel engines for medium and heavy-duty trucks,” according to DaimlerChrysler.

Detroit Diesel Chairman Roger Penske said he decided to sell because of “the competitive environment and the consolidation activity occurring within our industry.”

DaimlerChrysler’s plan to buy Detroit Diesel was revealed a few days after Wall Street was swept by rumors that Cummins Engine Co. was a takeover target.

DaimlerChrysler was listed as a possible bidder for Cummins along with General Electric, Fiat, Deere & Co. and Honeywell International.

However, Tim Solso, Cummins’ chairman and CEO, said the company is not for sale.
