Porsche's 718 Spyder RS: The Ultimate Gas-Powered Sports Car.

Porsche has unveiled the 718 Spyder RS, the final 718 model with a combustion engine. The convertible sports car is essentially a Cayman GT4 RS with its roof removed and a manually operated fabric roof in its place. It is powered by a naturally aspirated 4.0-liter engine borrowed from the 911 GT3, producing 493 horsepower and 331 pound-feet of torque. The Spyder RS is available to order in Germany from €151,215 and will be offered to US buyers starting at $160,700 plus a $1,450 delivery fee.
