AutoVIBES, partnering with Harris Interactive and Kelley Blue Book Marketing Research to track new vehicle nameplates, reveals that the 2005 Chrysler 300 is creating the most buzz of the 41 vehicles currently being tracked. Here are the top five:1. 2005 Chrysler 3002. 2004 Nissan Armada3. 2004 Cadillac SRX4. 2005 Pontiac GTO5. 2004 Nissan Titan"Relatively little was known about Chrysler's 300 until it hit the showroom with a bang," said Charlie Vogelheim, executive editor and vehicle expert at Kelley Blue Book. "It's no surprise that the 300 is No. 1 because it has been embraced by car buyers and the press alike. Chrysler hit a home run with the 300."The 300, which AutoVIBES tracked since January, began climbing in the study's ranking when it hit showroom floors in early April. It jumped from No. 14 during its pre-launch period, to No. 3 in April and reached the top spot in the May wave of the study."Nissan's two launches have generated a lot of attention, and they have done a good job of getting the word out about those vehicles," said Vogelheim. "It remains to be seen whether that buzz will translate into sales that will meet industry expectations."The top five were determined using survey data collected among in-market new-vehicle shoppers (within 12 months from a new purchase or lease) during May 2004. Factors that were taken into account were the awareness, favorability, and attribute ratings associated with each vehicle. All vehicles tracked in AutoVIBES are 'new' nameplates. Redesigned models were not considered.
