Too many guys view sedans as a decline into full-bore—as in boring— adulthood. For drivers focused on serious performance, driving a four-door has always felt like a compromise, a wrong turn toward the Early Bird buffet, with a multiyear detour through kiddie carpool territory. The day inevitably arrives, though, when a man wants the option of carrying a third or fourth passenger. Sometimes those passengers are even strapped into car seats. Luckily, in recent years carmakers have geared their high performance four-doors toward a younger audience looking for a balance of power and practicality.
