In tandem with the announcement on CO2 emissions reduction, Porsche pointed out that its current engine range is already engineered to run on E10, and that the Cayenne SUV can run on E25. A new FFV powerplant capable on running on gasoline alone or blends up to E85 is also being worked on, but there's no timetable for release at present.
This, combined with the confirmation this week that the Cayenne Hybrid is coming in 2009 and word that the system should be usable on all Cayenne powertrains -- including the monstrous 500-horsepower Turbo -- is great news for enthusiasts who'd like to have their cake and eat it too. One has to believe all this research will be applied in other areas sometime in the future. Can you imagine something like a biofueled 911 Turbo Hybrid somewhere down the line? I can. And I'm intrigued by the idea.
Press release after the jump, and we'll have more on Porsche in a little bit.

Porsche Reduces CO2 and Pollutant Emissions
Stuttgart. Dr. Ing. h.c. F. Porsche AG, Stuttgart, has set out to further
reduce the CO2 emissions of its cars by a significant margin. As the
Company announced at the Geneva Motor Show (5 – 18 March 2007), all Porsche
models, starting as early as next year, will comply with the strict EU5
emission standards applicable as of September 2009, at the same time even
fulfilling the currently defined limits of the EU6 standard not scheduled
to take effect until September 2014.
A further point announced by the company is that all Porsche engines are
already able today to run on fuel with an ethanol additive. This applies
both to Porsche's sports cars designed for a 10 per cent share of ethanol
and to the Cayenne sports utility vehicle able to run on a fuel mixture
with up to 25 per cent ethanol. With ethanol being a so-called bio-fuel
recovered from regenerating raw materials, this improves the overall
balance of CO2 by a corresponding figure of approximately 10 and,
respectively, 25 per cent. Porsche's Development Centre is also working on
a so-called Flexible Fuel Vehicle (FFV) able to run on both gasoline alone
and on a mixture of up to 85 per cent ethanol.
In its efforts to minimise fuel consumption and emissions, Porsche
currently gives top priority to the introduction of a hybrid engine which
the company is developing together with the Volkswagen Group and which is
planned to enter the market in a further variant of the Cayenne before the
end of this decade. This alternative drive concept will then reduce fuel
consumption by another 30 per cent, the hybrid Cayenne thus consuming less
than 9 litres of fuel on 100 kilometres (better than 31.4 mpg Imp).
Porsche plans to introduce a so-called "full hybrid" combining a gasoline
combustion engine with an electric motor. Benefiting from this system, both
power units can be run together and independently of one another, thus
allowing three different operating modes. In this process the electric
motor provides the power required not only when starting off at a moderate
pace or when manoeuvring, but also when driving in, say, residential areas.
Apart from ongoing efforts to reduce fuel consumption through consistent
lightweight technology and the use of innovative VarioCam Plus valve
management and direct gasoline injection, the planned measures serve not
only to significantly reduce CO2 emissions, but also to cut back the share
of nitric oxide in exhaust emissions by fulfilling the EU5 and EU6
standards ahead of time.
