The new Boxster and Cayman get upgraded engines which means the new 3.4-litre boxer engine is delivering 330 hp (Boxster GTS) and 340 hp (Cayman GTS). The GTS models also get revised suspension, wheels, brakes, and unique styling cues. If it was up to me I would take the new Cayman GTS, which in my opinion is the best looking Porsche since the first generation of 911.
