More affordable and a bit more driver-friendly than the 911, Porsche's entry-level rear-drive sports cars come standard with a mid-mounted 2.0-litre turbocharged flat-four engine that generates 300 horsepower. In S trim, displacement increases to 2.5 litres, resulting in 350 horsepower. And then there’s the GTS, which adds another 15 horsepower and brings extra sportiness and street cred to the table. The six-speed manual gearbox can be replaced by the seven-speed dual-clutch PDK.
