New 2021 Jaguar F TYPE Engines and Powertrain Explained
47All engines – 300PS turbocharged four-cylinder and 450PS and 575PS V8s – feature active exhaust systems, which are switchable either as an option or as standard. Customers who choose the 450PS or 575PS supercharged V8s benefit from the new Quiet Start function, which ensures a more subtle, refined sound – the electrically-actuated bypass valves in the rear silencer remain closed until they automatically open up under load. If desired, Quiet Start can be over-ridden by selecting Dynamic Mode or by pressing the switchable exhaust button before starting the engine.
The distinctive crackle and pop on the overrun synonymous with F-TYPE, remains; the sounds meticulously tuned to suit the range of powerful four and eight-cylinder engines. Highly efficient, close-coupled particulate filters reduce emissions.
