2018 Porsche Cayenne shows familiar shape in official sketch ahead of August 29 debut

Looks like we’re in for some subtle design changes

The wait for the third-generation Porsche Cayenne is almost over, as the automaker has confirmed it would pull the wraps off its all-new SUV on August 29 in Stuttgart, at 9 pm CEST.

The SUV appears to retain the shape of the current model, but we can't trust that a sketch accurately previews the production version. Porsche has already announced that the 2018 Cayenne will get a range-topping Turbo S E-Hybrid powertrain sourced from the Panamera. That version is expected to boast a total output of 680 hp and a system torque of 850 Nm (626 lb-ft).

Further down the range, expect similar V6 and V8 engine choices to the current model, including a diesel unit. The third-generation Cayenne may be the last to feature diesel engines, with Porsche announcing its strong commitment to hybrid and electric powertrains in the wake of Dieselgate.

The all-new 2018 Porsche Cayenne will have its formal world debut next month at the Frankfurt Motor Show.
