The Volkswagen Jetta enjoyed a serious boost in sales for the month of June, and it may have been thanks to an unlikely source – Katy Perry. The "California Gurls" singer performed at the company's launch of the redesigned Jetta, and the sales subsequently grew 88 percent over the same period of last year.

According to USA Today, the popularity among drivers is a change of tune from the thoughts of industry experts, who gave the new look Jetta less-than-favorable reviews. But consumers seem to be responding to the lower price and new look, as evidenced by the fact the June was the best month ever for Jetta sales in the United States.

Volkswagen will also be giving its Passat a new look, and new price for 2012, in the hopes that it can follow in the footsteps of the Jetta. The news source reports that the new Passat, which debuts in September, is a bit bigger than in previous years but still has the sport European feel that motorists enjoy.
