Porsche CEO, Mr Michael Macht, has told the UK’s Autocar magazine that the company will not build hybrid versions of its sports cars saying that both the 911 and Boxster models are “off-limits” as far as hybrid plans are concerned.
Although Porsche is still pushing ahead with its Cayenne S Hybrid SUV, Mr Macht has said that he doesn’t see the technology of batteries as being significantly advanced to live up to the manufacturer’s standards when it comes to pure bred sports cars.
Mr Macht also commented that such systems added considerable weight, while stating that as Porsche sports cars aren’t used primarily for daily commuting in the city, the advantages of a hybrid setup would not fully be realised, but did hint that Porsche is looking to hybrid-type advancements for its cars, including brake regeneration technology and a start-stop system.
The news comes on the same day that Porsche launches its Cayenne S Hybrid model in the US.
The SUV features a 248kW 3.0-litre V6 petrol engine – albeit supercharged and direct injection – that runs in parallel with a 39kW electric motor that’s sandwiched between the petrol engine and the car’s eight-speed automatic transmission. When operating together the system is capable of producing 278kW / 548Nm, or enough to accelerate the car from rest to 100km/h in 6.8 seconds.
As with other hybrid systems, the electric motor doubles as the starter motor and it reverses roles to capture the otherwise wasted energy in regenerative braking mode.
Fuel efficiency is further improved by adopting the usual electrically driven air conditioning and power steering. Electric motors also drive the transmission’s oil pump and provide the brake boost. In all, the hybrid system and its electric ancillaries shave fuel consumption by 28 per cent when compared with the conventional petrol-only Cayenne and its 3.6-litre V6 engine.
