There is so much that satisfies about the shapely 4-series, with power and performance that help it live up to its German heritage. Available as either a coupe or convertible with a folding hardtop, engines include the standard 240-hp 2.0-liter turbo four-cylinder or the gutsier 300-hp 3.0-liter turbo inline-six. Either engine offers a six-speed manual or eight-speed automatic and a choice of rear or all-wheel drive. The one letdown is vague steering, which detracts from the overall package.
