Escalade is latest SUV to get hybridized

BIRMINGHAM, Mich. – General Motors Corp. will test the market for a full-size luxury hybrid SUV when it releases the industry’s first vehicle in that category

Sales of GM’s other hybrid sport utility vehicles, the Chevrolet Tahoe and GMC Yukon, also have been slower than GM had hoped for. Through July, hybrids have made up 4 percent of total Tahoe and Yukon sales, fewer than the 5 to 6 percent GM predicted when the vehicles went on sale early this year.
