“That’s the way we’ve always done it.” Not really a sentence to inspire change. Except at Porsche. That’s because we’ve always made each new generation of engines higher-performing, more dynamic and more efficient than the last. The new engine generation of the Panamera models now takes the next significant step forwards.
The all-new twin-turbo V8 engine in the Panamera Turbo is lighter and more compact than its predecessor and comes equipped with VarioCam Plus. The two turbochargers are now positioned in between the cylinder banks. This reduces the distance that the exhaust stream has to travel to reach the respective turbo – delivering a more rapid response.
The twin-turbo V8 engine of the Panamera Turbo is equipped with twinscroll turbines. The exhaust streams arrive at the turbine wheel through physically separate channels – for optimized gas cycles. The result: high torque even in the low rpm range.
The adaptive cylinder control of the twinturbo V8 engine activates cylinders on demand. An example: you’re driving in town and have little need for power, your car will now operate on only four cylinders instead of eight. Once you demand greater power output again, all cylinders will immediately be reactivated.
The direct fuel injection in the new generation of engines is realised by a central injector inside the combustion chamber. This optimises both the mixture injection and combustion – for greater efficiency and increased power delivery.
