The 2006 Dodge Charger arrives as a ""muscle sedan"" counterpart to the visually more urbane Chrysler 300 that quickly became the most celebrated American sedan in decades when it was introduced in 2004. Both cars share nearly identical underpinnings,but the new Dodge product offers significantly different exterior styling with subtle Sixties overtones. The move to resurrect the Charger name on a four-door sedan still has many traditionalists in an uproar because the legendary Chargers of old were two-doors,but their din has been drowned out by a much larger group cheering this triumphant return of high-powered,rear-wheel drive sedans at mass-market prices.
