Carscoops spies have caught Porsche testing several prototype models of the limited production 911 Speedster on public roads. Designed as a last hurrah for the current-generation sports car, the 911 Speedster is based on the 911 GT3 chassis. While much of the design carries over, the Speedster has a unique hood and eschews the GT3’s massive rear wing.

The styling changes don’t stop there as the model adopts a unique soft top and rear deck lid. Porsche attempted to hide the changes by disguising the model as a traditional Cabrio but we can see the soft top is significantly smaller than what the company wants us to believe. The rear deck also appears to be sportier than the one used on the last 911 Speedster which arrived in 2010. As you can tell for yourself, it’s 95 percent production ready, with only some minor changes expected to be made to the model that will go on sale, like the mirrors and decals.


If the concept’s GT-sourced powertrain carries over, we can expect the model to  have a naturally-aspirated 4.0-liter six-cylinder engine that produces “more than” 500 hp and 459 Nm of torque. It enables the coupe to accelerate from 0-60 mph in as little as 3.2 seconds before hitting a top speed of up to 318 km/h.  For the record, the previous 911 Speedster was based on the 911 GTS. The study employed a six-speed manual transmission, but it’s not clear if it will be the only option or if Porsche will also offer its seven-speed PDK transmission.

While a lot of details remain unknown, we shouldn’t have to wait much longer to see the production model as Porsche has already begun teasing the next-generation 911. That particular model is expected to debut at the Paris Motor Show in October so it’s likely that the 911 Speedster will be announced before then.
