IRVINE, Calif. — The news that Hummer is in the process of officially winding down since General Motors could not find a buyer has apparently sparked a lot of consumer interest in the brand, particularly the H3, according to Kelley Blue Book's Hot Car Report for the week.

"The Hummer H3 experienced the greatest influx of shopper activity than any other high-trafficked model this past way," KBB officials explained. "Its 50.5-percent week-over-week increase can loosely be attributed to new concerning the brand limo status. Potential buyers may be scouting for incentives or deals similar to what has been offered on Pontiac and Saturn models."

The next most trafficked vehicle was the Mazda Tribute, up 26.3 percent, followed by the Infiniti M37, up 18 percent; the Suzuki SX4, up 17.8 percent and the Jeep Compass, up 14.7 percent.

The models that lost the most ground week-over-week in terms of traffic included the Toyota Tundra Double Cab, down 20.1 percent; the BMW 535, down 21.4 percent; Toyota Tundra Crewmax, down 21.5 percent; Lexus H5 250H, down 22.2 percent; and the Toyota RAV4, down 26 percent.

"Our assumption on Toyota's recent sales success is that it has been more than partially powered by incentive and bargain hunters and no greater evidence of this element of the American automotive shopper behavior is the recent huge increase in traffic to the Hummer H3," KBB officials pointed out.

As for weekly shopping activity growth on introduced and redesigned models, KBB found that the 2011 Infiniti M56 led the way with an upswing of 58.9 percent. Next up was the 2011 Infiniti M37, up 18 percent, followed by the 2011 Kia Sorento, up 1.4.

New or redesigned models that showed a downswing in traffic included the 2011 Ford F250 Super Cab, down 0.9 percent; the 2011 Hyundai Sonata, down 2.1 percent; the 2010 Hyundai Tucson, down 3.1 percent; the 2011 Toyota Sienna, down 3.1 percent; the 2011 Ford Fiesta, down 3.8 percent; the 2011 Ford F250 Crew Cab, down 7.1 percent; the 2011 Buick Regal, down 15.7 percent; and the 2011 Ford Mustang, down 17.8 percent.

"Also of interest is the combined activity in regards to the Infiniti M37 and M56, as this may show a new focus on the midsize luxury market and the importance of innovative and dynamic styling. This bodes very well for brands like BMW, Hyundai and Audi, who also will be introducing new and stylish vehicles in this competitive segment in the next 12 months," KBB executive said.
