Porsche second-best selling model, the Panamera, has added a hybridised V6 model.Mirroring the new Cayenne S Hybrid’s drivetain, the Panamera also features Audi’s supercharged 3-litre V6 S4 engine augmented by an integrated electric motor.Full hybrid output for the drivetrain is 279kW, which means the electric motor is worth 34kW.Interestingly the Porsche hybrid drive system’s electrification is powered by a less-than-contemporary nickel-hydride battery pack instead of a lithium-ion set-up, the latter favoured by most manufacturers for their hybrid models.Performance figures are keen; the 0-100km/h sprint is done in 6 seconds dead whilst top speed is 270km/h. Improved fuel economy is the raison d'être of any hybrid car (even a performance one) and to this end the Panamera Hybrid S is claimed to consume only 6.8l/100km. Unfortunately the Hybrid S won’t be quite as dynamically tuned-in as other Panamera models as it will only be available with an eight-speed automatic transmission, instead of Porsche’s Doppelkupplung seven-speed PDK option. LONG-WHEELBASE PANAMERA?Beyond the new Panamera Hybrid S (which is official, priced and availible), the rumour mill says that Porsche is preparing to pander to the tastes of its Chinese (and to a lesser extent, American) customers by releasing a long-wheel base version of the Panamera.In an attempt to provide optimal comfort for rear-seat passengers the Panamera is expected to gain additional axle spacing to the tune of 120mm, increasing the overall wheelbase to 3.04m. For a car which already possesses one of the most controversial side-profile views around any further elongation could prove an even more pronounced aesthetic demerit. Designers are expected to flesh out only the rear doors in an attempt to improve ingress and egress and hide some of the long-wheel base stretch’s bulk. Porsche is mum on the subject of a possible long-wheel base Panamera, but Chinese customers are expecting theirs late in 2012… In the meanwhile you can order the Panamera Hybrid S for R1 095 000.
