Under the hood, power will reportedly be provided by a twin-turbo 4.8-liter V8 engine that develops 550 PS (405 kW / 542 hp) and over 800 Nm (590 lb-ft) of torque. This should enable the hatchback to accelerate from 0-60 mph in less than 3.8 seconds and hit a top speed in excess of 188 mph (303 km/h).
If the reports are correct, the Panamera Turbo S will start arriving at dealerships in late June or early July.
