The first electric offering from Rolls-Royce, Spectre, has just completed a 2.5-million kilometre test program that simulates more than 400 years of use.
In the most demanding development process in its 119-year history, Spectre has endured temperatures ranging from -40°C to +50°C, in conditions spanning from Arctic snow and ice to deserts, high mountain passes and the world’s megacities.
The big, two-door coupe will ride on the same platform as the Phantom and Cullinan, and have a range of more than 500km.
A total 141,200 digital sender-receiver relations and 25,000 performance-related functions have been minutely observed, analysed and tuned by engineers, in a process representing more than 50,000 collective driven hours.
It has resulted in thousands of improvements in everything from Spectre’s acoustic performance, composure under cornering and steering precision to its charge time, electric range and torque delivery; each small in itself, but with an immense overall cumulative effect on the client experience.
Spectre has also been subjected to the marque’s unique Lifestyle Analysis process, enabling engineers to anticipate the very particular demands likely to be placed on a new Rolls-Royce and ensure that final engineered and fashioned experience incorporates appropriate features and responses.
Using this knowledge, engineers have considered a range of variables of particular relevance to Rolls-Royce clients.
For example, they have examined how Spectre’s drivetrain performs on specific roads in and around the world’s most exclusive enclaves, including: Sanya on Hainan Island, China; Dubai in the United Arab Emirates; Napa Valley in California; and London, in the marque’s home market.
This testing is not limited to performance under highway speeds.
Specific city centre destinations are also used to ensure that features such as four-wheel steering offer the requisite manoeuvrability benefits to access areas roads and property approaches with limited space.
Similarly, given the environments Spectre will be placed in worldwide, a large number of static testing procedures are undertaken that address key client concerns.
These include if it is possible to hold a normal telephone conversation inside the motor car while it is parked alongside a waiting helicopter, the strength of the motor car’s in-car internet connection between specific skyscrapers, and ease of access when placing specific objects inside the motor car – the long garment bags used to protect formal evening suiting and gowns.
As with the technical road testing, the Lifestyle Analysis phase of testing is in place to highlight necessary adjustments to the motor car’s specification or performance.
For example, after testing the power-assisted doors on an exceptionally steep hill – replicating the steep driveways common to the hills of Los Angeles, California – engineers added gyroscopic and G-force sensors to ensure that doors open and close at the same effortless speed, regardless of longitudinal or transverse parking angles.
Additionally, one corner was used so frequently to test the steering precision of Spectre, which the marque’s engineers believe is the most exact in Rolls-Royce history, they have named a switchback within the environs of Rolls-Royce’s home in Goodwood, West Sussex, ‘Spectre Corner.’
Fittingly, it was during Lifestyle Analysis testing in London, the capital of Rolls-Royce’s home market, that Spectre completed its 2.5-million kilometre odyssey in preparation for client deliveries, which will commence in the fourth quarter of this year.
“Spectre is the Rolls-Royce that changes everything,” Rolls-Royce Motor Cars Chief Executive Officer, Torsten Müller-Ötvös, said.
“It symbolises not only the marque’s technological leadership of the super-luxury sector, but that a bold electric future, first prophesised in 1900 by our founder, Charles Rolls, is now upon us.”
