One of the main complaints with the new 2017 Porsche 718 Cayman S is the sound. Switching from a naturally aspirated six-cylinder engine to 2.5-liter turbocharged flat-four will not only change the vehicle’s power output, but the sound as well and Car And Driver thinks the trade is worth it.
On paper, the 718 Cayman S is already better than its predecessor by generating 309 lb-ft of torque and 350 horsepower, which is 25 ponies more than what the old 3.4-liter six could produce.
There’s no turbo lag thanks to a variable-vane turbocharger and another benefit is the engine’s linear power and torque delivery. As shown by the dyno chart below, the S engine’s turbo is flat from 1900 to 4500 rpm, meaning drivers won’t have to drop a gear or wait for the tach needle before making a pass. In comparison, the 2.0-liter engine’s torque output has a point where it sags before steeply increasing.
Similarly, the 2017 Cayman S has a more linear power curve compared to the 2014–2016 Cayman S where you see a slight dip in power before the variable intake-valve system kicks in at around 4000 rpm. Some may like the feel of that power increase and the resulting exhaust note may have won over fans, but it doesn’t come as close to an ideal power curve as the new Cayman S.
With a seven-speed PDK dual-clutch automatic transmission, the new 2017 Porsche 718 Cayman S can be just as fun to drive and it’ll come with a whole list of new features.
