The overall 96-cell battery system from Axeon has a mass of 550 kg (1210 lb), and RUF states that "preliminary data" puts vehicle mass at 1910 kg (4210 lb).

An electric Porsche 911 prototype has been announced by RUF Automobile in Germany. Step-off acceleration to 100 km/h (62 mph) in about 7 s is claimed, and its single charge range is described as being better than 300 km (186 mi).

The eRUF 911 is equipped with a prototype advanced technology Axeon lithium-ion phosphate base battery. The battery has undergone a six-month evaluation program and is to be followed by a second prototype, which is expected to lead to a production model in 10-12 months, revealed Axeon. Battery capacity is 48 kW·h, and charging time is 10 h.

The eRUF 911 has a three-phase brushless ac electric motor with peak figures of 650 N·m (479 lb·ft) and 150 kW. Target performance of the production vehicle is a top speed of up to 225 km/h (140 mph) with a range of 250-320 km (155-199 mi) on a single charge. Initial acceleration is in the bracket expected of a 911.

The overall 96-cell battery system has a mass of 550 kg (1210 lb), and RUF states that "preliminary data" puts vehicle mass at 1910 kg (4210 lb).

The battery technology for the eRUF model is the latest in Axeon’s product lineup. The company, based in Scotland, already supplies its lithium-ion battery technology to the Modec commercial vehicle range as well as taxis and other vehicles converted by Allied Vehicles.

RUF is a producer of high-performance vehicles, specializing in manufacturing new RUF automobiles from the bare chassis and conversions to RUF specification. RUF has a long association with Porsche models.

Axeon Holdings plc describes itself as Europe’s largest independent supplier of lithium-ion battery solutions, manufacturing over 5 million battery packs a year across its applications.

Axeon designs and manufactures batteries and battery management systems for three main sectors: automotive, power tools, and mobile power. It also provides battery management systems for managing lithium-ion batteries.

Hamish Grant, CEO of Axeon, said: "RUF’s all-electric prototype car, equipped with a high-technology Axeon battery pack, demonstrates that electric-powered vehicles can perform in every sense. The world’s first all-electric German sports car from RUF, together with our other work for clients in need of less speed but more carrying capacity, demonstrates our capability to design and produce a range of batteries for electric and hybrid-electric vehicles with very different performance criteria. We look forward to working on the second prototype RUF vehicle."

The first eRUF prototype was built by U.S. specialist design and engineering company, CalMotors. It builds prototype vehicles with hybrid-electric and electric-only powertrains. CalMotors’ President, Mike Kasaba, said: "We chose Axeon as the battery supplier for its integration capability and independence from cell suppliers. We have been delighted with the support we have received during the development process."

Engine manufacturer Rolls-Royce is in many ways the leader in MRO support packages and was so even before the arrival of the digital revolution that allowed a transformation in support capability. This support extends into every aspect of operations, control, analysis of performance and through life maintenance and repair. Over the years, Rolls-Royce has consolidated its lead in comprehensive customer support activities alongside the continuous development of new advanced specification aerospace engines.
