Interesting rendering here of the Porsche 911 Turbo Cabriolet. Have a look!
Power for the model will be provided by a tri-turbocharged flat-six engine with roughly 550 PS (405 kW / 542 hp) in reserve which is a 20 PS bump on the previous model. It will be mated with the standard seven-speed manual or optional seven-speed PDK dual-clutch transmission.
Our best guestimates based on initial rumored specifications suggest the 911 Turbo will thrust from 0-100kph in 3.5 seconds and will have a speed that peaks at around 200mph.
