Recently, Porsche distributor Sime Darby Auto Performance previewed the Porsche Panamera Sport Turismo in Malaysia ahead of its official launch sometime next year. We were on hand to deliver a walk-around video tour of Zuffenhausen’s first ever wagon, which you can watch above.

We know that the Sport Turismo will be offered in base Panamera 4 and plug-in 4 E-Hybrid trims, along with the car you see here, the range-topping (for now, at least) Turbo. Although pricing information has yet to be released, the standard Panamera four-door already retails at a cool RM1.55 million for the Turbo, so expect a relatively modest price increase for the extra space.

Tacking Sport Turismo at the end gets you completely new bodywork aft of the B-pillar, with an elongated window line, an equally long roof contour and a sweeping rear windscreen, plus a prominent D-pillar that transitions into the shoulder section coupé style. There’s also a extendible roof spoiler, which generates up to 50 kg of downforce on the rear axle and also reduces drag and wind noise with the panoramic roof open.

Inside, the Sport Turismo is available with a centre rear seat for the first time on a Panamera, and can also be specified with two individual power-adjustable rear pews. Open the boot and you’ll find 20 litres of additional luggage space, at 520 litres for the petrol variants and 425 litres for the 4 E-Hybrid. With the seats folded, this can be expanded to 1,390 litres (1,295 litres for the plug-in hybrid).

Other than that, the Sport Turismo is identical to the sedan, with the Porsche Communication Management (PCM) infotainment system sporting a 12.3-inch touchscreen, forming part of the digital Porsche Advanced Cockpit that also includes touch-sensitive controls with haptic feedback. There’s also a range of driver assists including Porsche InnoDrive with adaptive cruise control.

The range of engines include a 330 PS/450 Nm 3.0 litre turbo V6 in the Panamera 4, which is paired with a 136 PS electric motor in the 4 E-Hybrid to produce a total system output of 462 PS and 700 Nm of torque. The Turbo gains a 4.0 litre biturbo V8 that punches out 550 PS and a whopping 770 Nm, enabling it to blitz the zero-to-100 km/h benchmark in 3.6 seconds before topping out at 304 km/h.

All models get Porsche Traction Management (PTM) all-wheel drive, plus rear-wheel steering, adaptive air suspension with new three-chamber technology and Porsche Active Suspension Management (PASM) dampers. Also equipped are the enhanced Porsche Dynamic Chassis Control Sport (PDCC Sport), Porsche Torque Vectoring Plus (PTV Plus) and active roll stabilisation, as well as electromechanical power steering.
