Power is provided by the 3.8-liter flat-six from the 911 Carrera S-that's right, Porsche's so serious about the Spyder that it finally dropped a 911 engine into a Boxster-rated at 375 horsepower and 310 lb-ft of torque. As a result, the 2016 Spyder gets a massive 55-horsepower gain over the first Boxster Spyder, and 45 over the top-spec Boxster GTS. A 6-speed manual is the only transmission; no PDK dual-clutch automatic available. Porsche claims a 0-60 mph time of 4.3 seconds and a top speed of 180 mph.
