/MODULAR EFFICIENCY PLATFORM
At Audi we group together all our technologies that promote
the further reduction of fuel consumption and CO
2
emissions
within the modular efficiency platform. This comprises an array
of building blocks in many different areas of technology that
are being steadily refined and elaborated. We are gradually
integrating these efficiency technologies into our various model
series in the form of product improvements and at model
changeovers. For example, the cylinder on demand technology
that can significantly improve fuel efficiency by deactivating
cylinders is already available in three engines. We brought a
further efficiency technology onto the market last year in the
new Audi Q7. The predictive efficiency assistant provides
anticipatory advice that helps the driver adopt an economical
driving style. In combination with adaptive cruise control,
speed can then be adjusted automatically – to comply with
speed limits or on bends, for example.
