At the 2018 Paris Motor Show held in October on the occasion of the 70th anniversary celebration of the marque, Porsche unveiled the Speedster variant of the 991 generation for the 911, as a concept.
Utilising the chassis of the GT3 and the body shell of the Carrera 4 Cabriolet, the Speedster sports a 4.0-litre naturally aspirated flat-six engine with a maximum power output of 500 PS (368 kW; 493 hp) and a red-line of 9,000 rpm coupled with a 6-speed manual transmission, which is claimed to be 4 kg (9 lb) lighter than the 7-speed manual transmission found on the standard 991 models, and a titanium exhaust system.
The car also features the signature "hump" shaped double bubble roof cover along with a shorter windshield frame, side window glass and the analogue roof folding mechanism retaining the "Talbot" wing mirrors and the central fuel cap from the 911 Speedster concept unveiled earlier at the Goodwood Festival of Speed harking back to its use on the 356 Speedster.
Other highlights include a leather interior with perforated seats, red tinted daytime running lights, carbon fibre fenders, engine cover and hood and stone guards.
Production will begin in the first half of 2019 and be limited to 1,948 units in honour of the year in which the 356 "Number 1" gained its operating license.

The final production version of the Speedster was unveiled at the 2019 New York Auto Show in April and dropped the "Talbot" wing mirrors in favour of standard 991 wing mirrors and announced to be available for sale in May 2019.
The engine adopted from the GT3 is equipped with individual throttle bodies and a new fuel injection system and develops 510 PS (375 kW; 503 hp) at 8,400 rpm and 470 N⋅m (347 lb⋅ft) at 6,250 rpm.
The exhaust system is claimed to be 10 kg (22 lb) lighter despite the addition of two petrol particle filters.
The car is equipped with carbon-ceramic brakes (PCCB) as standard, a Heritage Design Package is available as option.

The Speedster was also the final edition of the 991, with only 1,948 units produced.
Production of the 991 generation ended on December 20, 2019 and the final 991 model was a 991 Speedster.
Porsche made 233,540 991s worldwide.

The last unit of the Speedster was auctioned off in April 2020.
