Toronto -- Porsche is adding two distinctly sporty and high specification models to its mid-engine sports car range: the 718 Cayman GTS 4.0 and the 718 Boxster GTS 4.0. A naturally aspirated four-litre six- cylinder boxer engine developing 394 horsepower and 309 lb.-ft. of torque, powers the new mid-engine sports cars. This engine is closely related to the 414 horsepower variant used in the 718 Spyder and the 718 Cayman GT4. Equipped exclusively with a six-speed manual transmission and standard Sport Exhaust System, the 718 GTS 4.0 models offer exceptional throttle response and a particularly rewarding driving experience. Both can accelerate from 0 to 100 km/h in 4.5 seconds and reach a top track speed of 293 km/h. Porsche Active Suspension Management (PASM) sport suspension with a 20 millimetre lower ride height compared to standard 718 Boxster and Cayman models is standard, as is Porsche Torque Vectoring (PTV) with a mechanical limited-slip differential. As a result, the new 718 GTS 4.0 balances nimble handling and ride comfort exceptionally well. The standard Sport Chrono package with upgraded Porsche Track Precision App also underscores the driving enthusiast-oriented character of the mid-engine sports cars. Black contrasting design elements and a dark Alcantara® interior are highlights typical of GTS models.
