About the Porsche 911 Speedster 991
The 991-generation Speedster serves as the ultimate farewell to one of Porsche's most successful 911 eras. Developed by the GT department, it borrows the high-revving 4.0-litre engine from the GT3, enhanced with individual throttle bodies for even sharper response. Its design is defined by a shortened, raked windscreen and a signature carbon-fibre 'double-bubble' rear deck, paying homage to the 356 Speedster. Available exclusively with a six-speed manual gearbox, it prioritises tactile engagement and mechanical purity over outright lap times.
