The low-resolution images of the forthcoming eighth-generation 911 were published by Jalopnik, which says it was sent them by a user of a private internet forum where they first appeared.
Numerous test mules of the 992 generation machine have already been spotted, including some with virtually no camouflage. The leaked images showcase the more muscular look of the new machine, with a design inspired by the 997-era 911 Speedster. That model, in turn, was inspired by Speedster models of the 1950s and 1960s. Autocar has already had a ride in a prototype of the new 911.
The new photos also clearly show the reworked rear end of the new car, which is similar to the Mission E concept, and thus the Taycan, due next year. The design employs the familiar subtle evolution Porsche has employed for decades, but extensive changes to the powertrain range will feature.
For the first time, every petrol engine in the 911 line-up will be turbocharged, marking the end of naturally aspirated units found in more hardcore variants of the current 991.2-generation model.
The new 911 line-up will also include two new four-wheel-drive plug-in hybrid models, including a range-topping version with more than 600bhp and a top speed of nearly 200mph.
Although the Jaguar F-Type rival will be launched with traditional combustion-engined Carrera and Carrera S models, the petrol-electric versions will be an integral part of the line-up. A senior Porsche official has told Autocar that Carrera 4 E-Hybrid and Turbo S E-Hybrid variants will be added to the model line-up in 2020.
