Engines.
Increasing power output, reducing fuel
consumption. Brief fulfilled. With engines
characterised by sporty performance
and yet comparatively low energy
consumption and CO
2 emissions.
This has been achieved thanks to
technologies such as direct fuel injection
(DFI), VarioCam Plus or variable camshaft
control, turbocharging, recuperation,
the auto start/stop function, the coasting
function or the use of plug-in hybrid
technology. The engines are structurally
rigid and, thanks to aluminium cylinder
heads and magnesium valve covers (except the Panamera S E-Hybrid), they
are comparatively light weight. This helps
to ensure a decent weight-to -power
ratio and balanced weight distribution.
Let’s take the new engine generation of
the Panamera S and Panamera 4S as
an example. It may have been stripped
of t wo cylinders and its displacement
reduced by 1.8 litres compared with
that of its predecessor, but it has been
given a twin-turbocharger arrangement.
This is where the figures begin an
upward trend. Increased power output,
greater dynamics and enhanced
e f f ici e n cy.
Direct fuel injection (DFI).
With millisecond precision, DFI injects
fuel at up to 120 bar directly into the
combustion chamber by means of
electromagnetically actuated injection
valves. DFI also improves the internal
cooling of the combustion chamber by
having the mixture prepared directly in
the cylinder. The higher compression ratio
helps to deliver more output at the same
time as enhanced engine efficiency.
