When it comes to firearms, the word “caliber” refers to the size of the bullet a gun uses. And – generally speaking – the larger the caliber, the bigger the bang you can expect when you pull the trigger. The new 2007 Dodge Caliber is an exception this rule. As the Dodge brand’s new small car built for both domestic and worldwide markets, this compact crossover vehicle seems poised to make an impact on the small car segment that goes well beyond its modest size. That’s because the Caliber is a car that manages to blow away the time-worn maxim that small, inexpensive cars are nothing more than basic transportation for folks on a tight budget.
