It cannot be denied, however, that
with the introduction of these models, speculation began as to
whether these cars represented the last production series of the types and heralded a new series of
models to be released to the public.
Such speculation apart, the Silver
Spirit II and the Silver Spur II had more than skin-deep differences
to their forebears. By taking advantage of the advances made in technology, particularly in electronics,
the engineers at Crewe had reworked the Rolls-Royce self-levelling system and
developed a suspension without an equal in the world.
Vertical, longitudinal and lateral
accelerometers monitored acceleration, road surface conditions and braking
and sterring changes. All data from external transducers and switches were received by a
microprocessor control unit. This information was compared continuously with programmed
threshold values for each switching control and the damper values adjusted as necessary
The interior of Silver Spirit II
gained modest, although useful, alterations and additions.
An extensive programme of ergonomics research led to a
level air conditioning could
be tuned more precisely due to two additional outlets in the
A sound system with ten speakers and a 100 watt amplifier was considered to provide
concert hall quality.
Heated front seats with an electrically operated lumbar support and a
leather trimmed two-spoke steering wheel underlined how carefully Rolls-Royce had
considered any feature which
would make the new product a true driver's car.
Rolls-Royce had produced a pair
of very desirable motor cars and now saw the need to provide an
anti-theft alarm as standard thus helping keep their customers' precious possessions from
changing hands in an unintended way.
