In a relatively short period of time, cars
and motorcycles have become essential tools for many of us. However, some vehicles
do more than simply transport us from place to place, they have a power and a
beauty which captures the imagination. A new exhibition at Adelaide's National Motor
Museum, Velocity: Built for Speed presents some of these cars and motorcycles.
The exhibition explores five key themes:
Going slowly – red tape and red flags Looking at when the first
cars started to appear on roads including fears that they would endanger
pedestrians and terrify horses. Legislation controlled the speed of mechanically
propelled vehicles and even required that each vehicle be accompanied
by someone with a red flag walking 60 yards (55 metres) ahead of the vehicle.
Going fast – aerodynamics Streamlining and aerodynamics have
played an important role in the quest for speed and the 1930s saw smooth
curvilinear shapes replace the blocky ‘horseless carriages’ of the previous age.
Aerodynamics is the science of how air flows around an object and designers must
consider two major factors - drag and downforce.
Going faster – giving it grunt The first half of the twentieth
century saw a trend to increase engine power, particularly in the American
models and design changes incorporated all known methods of raising engine
capacity.
Going fastest – land speed records Even before 1900 the 100
km/h barrier had been broken. In 1970 the 1,000 km/h record was broken. But it was
not until 1997 that the sound barrier in a land vehicle was broken, when a speed
of almost 1,228 km/h was recorded.
Stopping dead With all this talk of speed, one must consider
the negative side - higher speed increases the risk of crashes and injuries. The
thrill of going fast has significant risks and is dangerous even for
experienced, skilled drivers.
On show will be examples of cars and bikes that are designed to go fast, such
as:
- 1990 Streamliner land speed racer
- 1970 Lamborghini Miura
- Torana A9X
- 1971 Chrysler Valiant Charger
- 1972 Kawasaki Z1A 900
- 1916 Indian motorcycle
