The 2008 Porsche Boxster is largely unchanged. These two-seat mid-engine convertibles share their basic designs with Porsche's Cayman hatchback coupe. Like the Cayman, Boxster has front and rear cargo compartments and horizontally opposed 6-cylinder engines. Boxster has a power folding soft top. Base and S trim levels are available. Base models have 245 hp from their 2.7-liter 6-cylinder, and S versions have 295 hp from their 3.4-liter engine. Manual or automatic transmission is offered. Available safety features include ABS, traction control, antiskid system, and side airbags that protect the head and torso. Options include a navigation system and Porsche's Sport Chrono Package with a dashboard stopwatch and sensors that modify throttle, traction, and suspension systems to suit racetrack-type driving. Also optional is Porsche's Active Suspension Management with normal and sport settings. Newly available are base and S Limited Edition models, which have specific interior and exterior trim.
