Porsche Unveils New 718 Spyder and Cayman GT4
Porsche has unveiled the latest additions to its 718 mid-engine sports car family: the Spyder and the Cayman GT4. For the first time ever, the two cars — one a convertible, the other a grand touring car — share the same technical base, including a new 4.0-liter six-cylinder boxer engine rated at 414 horsepower and 310 lb-ft of torque.
With the manual transmission, Porsche says both cars will top out over 300 kph (186 mph) and both cars will accelerate from 0 to 60 mph in only 4.2 seconds. “The unparalleled boxer sound remains untouched,” the automaker says — not that it would be easy to muck up the engine note of an 8,000-rpm, naturally-aspirated boxer.
Porsche somehow found a way to increase the 718 Cayman GT4’s aerodynamic downforce by 50 percent, even though non-enthusiasts would probably be unable to tell the car apart from its predecessor. That’s largely thanks to the rear diffuser, which accounts for 30 percent of the car’s rear downforce.

Unlike the GT4, the 718 Spyder has a rear spoiler that automatically raises itself at 75 mph (the GT4’s spoiler is simply fixed), but like the GT4, it now also benefits from a rear diffuser. In fact, the two cars share a lot more features than they used too now that they ride on the same GT chassis, which essentially means that the Spyder is now a much quicker, sharper-handling car.
Both cars offer ceramic composite brakes as an option, and both cars also feature new super-sticky tires specially developed by Porsche, with which the GT4 was able to achieve a lap time around the Nürburgring Nordschleife that was 10 seconds faster than the previous model.
