The auto start/stop function, used by Porsche for the first time in the new Panamera – and only available in conjunction with PDK – reduces fuel consumption and hence emissions. For example, if you're waiting at traffic lights with your foot on the brake, the system automatically switches off the engine. As soon as you release the brake, it starts again. This saves fuel: in the city, up to 10 % and overall by more than 5 %.*
Fuel consumption/emissions* of the Panamera models: Urban in l/100 km 17.0 (16.7**)-8.1 (7.8**); Extra urban in l/100 km 8.4 (8.3**)-5.6 (5.5**); Combined in l/100 km 11.5 (11.3**)-6.5 (6.3**); CO2 emissions in g/km 270 (265**)-172 (167**).
