Sime Darby Auto Performance has previewed the Porsche Panamera Sport Turismo earlier today at its Sungai Besi showroom. The wagon version of Zuffenhausen’s second-generation sports sedan makes its debut in range-topping (for now) Turbo trim – the exact car seen on a trailer a couple of weeks ago.

The distributor said that the car will be launched some time next year and will come in base 4 and top Turbo variants, skipping the 4S and 4S Diesel models; there will also be a plug-in 4 E-Hybrid model available. No pricing information has been announced just yet, but just for your reference, the standard Panamera four-door retails at RM1.55 million for the Turbo, so expect a 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.

As far as measurements are concerned, the car occupies a footprint no larger than the standard Panamera, measuring 5,049 mm long and 1,937 mm wide; the 2,950 mm wheelbase is also shared with the sedan. However, the Sport Turismo is a nominal 5 mm taller, at 1,428 mm. Wheel options measure up to 21 inches.

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).

A luggage compartment management system is available on request. Among other things, this variable system includes two rails integrated in the loading floor, four lashing points and a luggage compartment partition net. An optional 230V electrical socket can also be provided in the boot.

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 start off with the 3.0 litre turbocharged V6 in the 4, producing 330 PS at 5,400 rpm and 450 Nm between 1,340 rpm and 4,900 rpm. Equipped with an eight-speed PDK dual-clutch transmission and standard-fit Porsche Traction Management (PTM) permanent all-wheel drive, it sprints from zero to 100 km/h in 5.3 seconds (with launch control) before hitting a top speed of 259 km/h.

Moving up to the 4 E-Hybrid pairs that engine with a 100 kW (136 PS) electric motor to provide a total system output of 462 PS at 6,000 rpm and 700 Nm from 1,100 to 4,500 rpm. As equipped, the Sport Turismo slashes eight tenths off the 0-100 km/h time at 4.6 seconds and has a significantly higher top speed of 275 km/h.

The big daddy Turbo comes swinging with a 4.0 litre biturbo V8 that punches out 550 PS at 5,750 rpm and 770 Nm between 1,960 and 4,500 rpm, smashing past the 100 km/h in just 3.6 seconds and maxing out at 304 km/h. The engine also features active cylinder deactivation that reduces fuel consumption by up to 30%.

Elsewhere, there’s the same rear-wheel steer system adapted from the 918 Spyder and 911 Turbo, adaptive air suspension with new three-chamber technology and Porsche Active Suspension Management (PASM) dampers. Also on, an enhanced Porsche Dynamic Chassis Control Sport (PDCC Sport) system, Porsche Torque Vectoring Plus (PTV Plus) and active roll stabilisation, as well as electromechanical power steering.
