Rolls-Royce released more details on its upcoming Specter EV this morning, highlighting recent winter testing and providing more details on the new Rolls-Royce 3.0 digital chassis and chassis.
The Rolls-Royce Specter EV recently completed the winter phase of a planned 2.5 million kilometer test drive for the new luxury car announced last year. When the full test cycle is completed, the Specter will have simulated more than 400 years of use, Rolls-Royce said. The winter part was held in Arjeplog, Sweden, 55 km from the Arctic Circle.
Freezing temperatures (between -26 and -40 degrees) allowed Rolls-Royce to test the resistance of the Specter’s heating system and weather to the elements. Rolls-Royce engineers also used ice and snow-covered roads to test the changing low-speed conditions that would normally occur at higher speeds and programmed the Specter EV’s performance to respond appropriately to these conditions.
Rolls Royce 3.0
Rolls-Royce also announced its new generation of architecture called Rolls-Royce 3.0, a continuation of the previous two Rolls-Royce series launched after Rolls-Royce arrived at Goodwood in 2003. The first generation Phantom was designed with Bespoke architecture, while the second The all-aluminum space frame architecture on which the current Phantom, Cullinan and Ghost are based is considered Rolls-Royce architecture 2.0.
Rolls-Royce 3.0 aims to integrate an all-electric powertrain into the company’s architecture while digitizing the chassis. More than 1,000 functions and 25,000 sub-functions are integrated into the architecture, compared to just 456 and 647 respectively in the current Rolls-Royce Phantom.
What does all this mean, exactly? Rolls-Royce explains it better than we can:
“The greatly increased intelligence of the electrical and electronic architecture of Specter allows detailed information to be exchanged freely and directly between these more than 1,000 functions, without intermediate processing. Although this required engineers to increase the length of cables from almost 2 kilometers in the product existing Rolls-Royce up to 7 kilometers on the Spectre, and writing more than 25 times more algorithms, represents a significant step forward for the brand. A specific controller can be created for each set of functions, allowing unprecedented levels of detail and optimization to be achieved, and achieve what Rolls-Royce chassis experts are already calling “High Definition Rolls-Royce”. “.
The Rolls-Royce Specter EV will have a drag coefficient of just 0.26, which is undoubtedly an improvement over the current Phantom and Ghost, and the material used to insulate the Specter’s battery is equivalent to 700kg of additional soundproofing material.
Rolls-Royce’s new electric car has now completed 25% of its initial testing. The remaining testing phase is expected to be completed before the first Specter EV deliveries are expected in late 2023.
