The Panamera S E-Hybrid is one of the most advanced Porsches ever, thanks to a plug-in hybrid system which combines a 3.3-litre petrol V6 engine with a 134 bhp electric motor driving all four wheels through an 8-speed Tiptronic S automatic gearbox. The system is designed to provide a moderate electric-only range of between 15-31 miles at up to 88 mph and moderate the fuel consumption of the petrol engine at all other times.
The electric range allows the Panamera to qualify for super low company car tax, and exemption from the London Congestion Zone charge. If you can regularly keep within the electric range (Monday – Friday commute) then it is capable of very low CO2 and other exhaust emissions.
Once you run out of electric-only range the motor will still chip in like any hybrid but fuel consumption is likely to be in the mid-30’s mpg equating to around 190g/km. The upshot is that if you will do lots of electric running it does make sense, if you won’t the diesel Panamera is a better real-world solution.
Apart from the price, the only compromises are a smaller boot (335 litres), no manual gearbox option, and no four-wheel drive option. The upsides are very low tax, very low running costs in electric mode, and despite the two tonne kerb weight, physics-defying body control and a very neutral balance. It remains a niche product but the Panamera proves that in the right circumstances space, pace and driving enjoyment can be combined with low emissions.

Please note that CO2 emissions quoted for electric cars are not directly comparable to diesel and petrol cars. This is because CO2 emissions quoted are calculated by Green Car Guide and include the emissions created at the power station turning fuel (e.g. gas etc) into electricity and in transmitting and distributing the electricity to an end user. They do not include the actual production of the fuel (e.g. gas extraction and refinery emissions). Petrol and diesel emissions are supplied by car manufacturers and are based solely on the fuel burnt in the engine (tailpipe emissions) and do not include the production of the fuel or distribution to a fuel station. In practice this means that electric car emissions are over-estimated relative to petrol and diesel. For instance if an electric car, a petrol car, and a diesel car are all reported to emit 100 g/km CO2, the electric car actually has lower emissions.
