Rolls Royce Spectre Winter Testing
15In September 2021, Rolls-Royce Motor Cars made an historical announcement that it would launch its most important product since 4th May 1904, when the marque’s founders Charles Rolls and Sir Henry Royce agreed that they would create “the best car in the world”. The Rolls-Royce Spectre.
While Rolls-Royce has built a reputation for creating what are regularly described as “the best cars in the world” using internal combustion engines, the idea of electrification is something that is familiar to the brand. Henry Royce began life as an electrical engineer and dedicated much of his life to creating internal combustion engines that simulated the characteristics of an electric car – silent running, instant torque, and the sensation of one endless gear.
A new Rolls-Royce motor car always begins its life in winter. Temperatures at the Bespoke facility used by the marque, located in Arjeplog, Sweden, just 55km from the arctic circle, drop to -26 degrees centigrade and are further cooled to -40 degrees centigrade.
There are several reasons for subjecting the marque’s products to such extremes. When the first prototypes are built, engineers perform very basic tests in extreme conditions to ensure that each system is operational and functions at a basic level in a cold weather environment. This test is combined with the beginnings of the refinement process – the first ‘lessons’ in a finishing school that will form the foundations of a motor car worthy of the marque.
This begins with processes that are common to the automotive industry such as noise, vibration and harshness tests. The variables that affect this are manifold, spanning from the materials selected for major hardware components to the density of the door rubbers, bushing compounds, fastening materials and even properties of bonding agents. The performance of these variables can change considerably when subjected to extreme temperatures – likewise the efficiency of the motor car’s heating, ventilation, air conditioning and cooling systems.
