Porsche’s new 374bhp hybrid Panamera S has been launched at the Geneva motor show.
It will go on sale in June boasting the lowest CO2 output of any sporty large saloon - just 159g/km in the combined EU test cycle, beating diesel-powered competitors like the Jag XJ and BMW 7-series by between 19 and 25g/km.
Significantly the CO2 output is below a government threshold of 160g/km that for tax purposes allows businesses to write off more of the cost of the car, which should boost its appeal to company drivers.
The Panamera’s powertrain is shared with the Cayenne hybrid and is centred on a 330bhp supercharged 3.0-litre V6 sourced from Audi. It’s a different engine family to the 295bhp 3.6-litre V6 that powers other Panamera models.
The hybrid mates the 3.0 V6 to a 44bhp electric motor, which doubles up as the starter/generator and is packaged alongside a clutch, so that either petrol or electric power can provide drive.
