Aug. 20 (Bloomberg) -- General Motors Corp. hasn't yet sought offers or discussed the sale of the Hummer sport-utility line with potential buyers, the brand's general manager told dealers.

``GM did receive expressions of interest from various entities,'' Martin Walsh said in a video sent to U.S. retailers yesterday. ``But we have never solicited offers and we have not negotiated with any parties.''

He labeled as ``just speculation'' media reports that GM has engaged in talks with Indian companies Mahindra & Mahindra Ltd. and Tata Motors Ltd. as well as Russian billionaire Oleg Deripaska's Russian Machines. Joanne Krell, a spokeswoman for the Detroit-based automaker, confirmed the video.

Chief Executive Officer Rick Wagoner said June 3 that GM is reviewing Hummer for a possible revamping or sale after purchases fell 36 percent through May from a year earlier, the most among any brand in the U.S. The automaker hired Citigroup Inc. to help study the unit.

``The review is being conducted with the utmost urgency and integrity,'' said Walsh. The video was a regularly released business update.

Through July, Hummer sales in the U.S. plummeted 44 percent to 18,035 units, according to Autodata Corp. of Woodcliff Lake, New Jersey.

The automaker is making ``significant progress'' on a plan that began in January to help improve Hummer dealer profitability on a case-by-case basis, Walsh said. He disputed media reports that said GM is working to buy out multiple dealerships.

U.S. Hummer dealers averaged 11 sales each in July, down from 12 in June and 28 apiece in July 2007, according to trade magazine Automotive News. The 102-day supply of Hummers on Aug. 1 exceeded the 98-day industrywide average for all types of trucks and was more than double the inventory of cars.

U.S. Hummer sales peaked in 2006 at 71,524 units, before dropping 22 percent last year.

GM gained 21 cents to $10.16 at 4:15 p.m. in New York Stock Exchange composite trading. The shares have lost 59 percent this year.
