But from September the brand could be well placed to make a greater impression, particularly among eco-focused businesses.
The Cayenne, which is mechanically similar to the Volkswagen Touareg, offers competitive CO2 emissions and running costs with cars such as the BMW X5 and Mercedes-Benz ML, while the same powertrains in the Panamera have given senior executives access to a driver-oriented saloon in the same price bracket as BMW, Mercedes-Benz, Audi and Jaguar rivals.
The Panamera Hybrid caught people’s attention as a company car because of its CO2 emissions of 159g/km, which, at launch, fell below the 160g/km threshold for enhanced capital allowances.
However, changes were made in April and the threshold was reduced to 130g/km, taking many popular company cars out of contention, let along high-performance choices for senior executives.
But Porsche was well advanced along the road to the next stage of its hybrid programme, and the facelifted version of the Panamera comes with a plug-in hybrid model.
The Panamera S E-Hybrid comes with CO2 emissions of just 71g/km and fuel consumption of 91.3mpg on the official combined cycle.
This makes it sound like an ultra-economy version but performance-wise it’s placed squarely in the middle of the Panamera range.
The combined output of both petrol and electric power is 416bhp, with a maximum torque output of 435lb-ft, enough to propel the car from rest to 62mph in just 5.5 seconds.
The 71g/km rating takes it out of July’s new lower CO2 limit for the London congestion charge zone, ensures it’s in 100% write down allowance territory and falls into the lowest BIK tax band, which will also minimise employers’ National Insurance contributions.
Whether it will qualify for the £5,000 plug-in car grant or not is still being discussed, but this should be resolved by the time deliveries commence in September.
But this is still an expensive and relatively exclusive car and should not see a significant rise in sales, although it should make Porsche much more visible to fleet operators and high-end user-choosers.
A smartphone app allows the driver to check the status of the car’s range and charge remotely, as well as flash the lights or sound the horn to make it more visible when returning to it in a car park.
The car will come with a free home charging unit, although the fitting of the unit will need to be arranged and paid for by the customer.
The Panamera facelift is subtle: minor cosmetic changes with new headlamps, rear light clusters and bumper designs mark out the new model, although the instrument panel of the plug-in hybrid is different from other models in the range.
