Following the launch of the Panamera V6 line-up earlier this year (due in Australia from July), Porsche has announced a number of updates to the four-door super-saloon's V8 range.
Launching internationally in August, the V8-powered 2011 Panamera S, 4S and Turbo will benefit from a new brake-energy recovery system fitted as standard, designed to charge the battery when the brakes are applied.
Combined with optional 19-inch low-rolling-resistance tyres and the engine's Start & Stop system, the updated Panamera Turbo uses 11.3 l/100km (down 0.9 l/100km), while the S and 4S are down to 10.3 and 10.6 l/100km respectively.
Porsche has also added its Porsche Torque Vectoring Plus (PTV Plus) and Porsche Dynamic Chassis Control (PDCC) systems to the 2011 Panamera V8's options list, along with a fully-controlled rear axle differential lock.
PTV Plus is designed to improve steering behaviour, intervening in the brakes on the inner rear wheel in a bend and generating an additional rotational force acting in the same direction as the steering wheel.
Working with the rear axle differential, Porsche says its PTV Plus system also improves traction at the rear wheels when accelerating out of a corner.
Other updates include new paint and leather options, along with new equipment, including auxiliary heating and a three-spoke sports wheel with paddle shifts for the Gran Turismo model.
It's unclear at this stage when the updated Panamera V8 range will arrive in Australia; Porsche has been contacted for more information.
