Following last week’s teaser, Porsche has introduced the new 718 Boxster Spyder and the 718 Cayman GT4.
Designed to be the pinnacle of the 718 lineup, both models are equipped with a newly develop 4.0-liter boxer engine. The six-cylinder is naturally aspirated and produces 414 hp (309 kW / 420 PS) and 310 lb-ft (420 Nm) of torque.
The engine is connected to a six-speed manual transmission which enables both models to accelerate from 0-62 mph (0-100 km/h) in 4.4 seconds. The top speeds are slightly different as the 718 Spyder maxes out at 187 mph (301 km/h), while the 718 Cayman GT4 tops out at 189 mph (304 km/h).
Despite the focus on performance, the engine has been equipped with an adaptive cylinder control system that “temporarily interrupts the injection process in one of the two cylinder banks” to reduce fuel consumption. The engine also has a variable intake and piezo injectors. The latter are notable as Porsche says this is the first time they have been used in such as a high-revving engine.
