The eagerly-anticipated Porsche Panamera specifications have been released in full. The Panamera range comprises of three models, the Panamera S, Panamera 4S and Panamera Turbo. All are powered by a 4806 cc all-aluminium direct petrol injection V8, featuring twin overhead camshafts and 4 valves per cylinder, with Porsche's VarioCam Plus variable valve timing. The 4S and Turbo Panameras have full-time all-wheel drive and feature Porsche's new PDK double-clutch transmission, whilst the Panamera S is rear wheel drive and is available with either a six speed manual shifter or the 7 speed PDK transmission.
The 4 door saloon body measures just under 5 metres in overall length, at 4970 mm. The wheelbase is a fairly long 2920 mm, and it is a wide car, at 1931 mm. This impacts the frontal area significantly, with all models having a frontal area of 2.33 m2. The Panamera Turbo has a decent 0.30 coefficient of drag, and the Panamera S and Panamera 4S a very good 0.29.
Porsche's 4.8 litre V8 engine is oversquare, with a 96.0 mm bore and an 83.0 mm stroke. The Panamera S and Panamera 4S are naturally aspirated, with a compression ratio of 12.5:1, and produce 400 PS at 6500 rpm, with 500 Nm of torque from 3500 to 5000 rpm. The Panamera Turbo runs at a lower 10.5:1 compression ratio, and with its twin turbochargers produces 500 PS at 6000 rpm, with torque of 700 Nm between 2250 and 4500 rpm, or 770 Nm at the same revs for the Sport Chrono Package-equipped models.
The manual Panamera S weighs 1770 kg, and has claimed acceleration figures of 5.6 seconds for 0-100 km/h, 12.1 seconds for 0-160 km/h, and takes 24.5 seconds to cover the standing kilometre. Its top speed is a stated 285 km/h. With the PDK transmission, the S shaves 0.2 of a second off the 0-100 km/h time, hits 160 km/h from rest in 11.7 seconds, and the standing kilometre is covered in 24.3 seconds. Top speed is slightly lower at 283 km/h. CO2 emissions are 293 g/km and 253 g/km respectively.
The 4S tips the scales at 1860 kg, and boasts slightly quicker acceleration. The 0-100 km/h dash takes it 5.0 seconds, 0-160 km/h 11.5 seconds, and the standing kilometre 24.0 seconds. The top end is slightly lower, at 282 km/h. CO2 emissions are slightly worse than the PDK Panamera S, at 260 g/km.
With its twin turbos giving it a boost, the Panamera Turbo storms through to 100 km/h from rest in 4.2 seconds, hits 160 km/h in 9 seconds dead, and runs through the standing kilometre sprint in 22.1 seconds. It is claimed to carry on to a top speed of 303 km/h, and has CO2 emissions that just beat the standard manual Panamera S, at 286 g/km.
