Rolls-Royce signs deal to trial hybrid-electric train conversions

LONDON — Rolls-Royce has signed an agreement to conduct a trial conversion of diesel trains to hybrid-electric engines in Britain, in a deal which could be rolled out to hundreds of trains across the country starting in the 2020s. The British company, which is best known for making aircraft engines, said on Wednesday that its German Power Systems business had signed an agreement with Porterbrook, the UK's largest owner of passenger rolling stock. Rolls-Royce's Power Systems unit, which sells engines used on ships, yachts, trains, trucks, mining and nuclear power stations, is one of the fastest growing parts of the company, and its boss said hybrid technology is behind that. "We expect hybrid technology to grow at above the current growth rates of diesel," the CEO of Rolls-Royce Power Systems, Andreas Schell, told Reuters. The Power Systems business is expected to post low double-digit revenue growth this year and is a bright spot in a company grappling with the negative headlines and cost of fixing a problem with its Trent 1000 aero-engines. Diesel trains can be fitted with Rolls-Royce Hybrid PowerPacks to turn them into hybrid trains that can also run on battery power, reducing carbon emissions and making them cheaper to run for operators while also making them much quieter when, for example, they approach stations. From RR's press release: The MTU Hybrid PowerPack is an environmentally friendly drive system which combines the advantages of diesel and battery-powered rail traction. The version for Porterbrook incorporates an MTU diesel engine which fulfils future EU Stage V emissions regulations; plus an electric machine, which can be used either as an electric motor or generator; and an MTU EnergyPack battery system, which stores the energy recovered during braking. This enables very low-noise, emissions-free battery-only electric operation in urban areas and around stations. The hybrid initiative comes as Britain seeks to phase out diesel-only trains by 2040. Adding the powerpacks to trains allows railway networks to be partially electrified without the need for expensive overhead infrastructure. The Institution of Mechanical Engineers says that 42 percent of Britain's rail network is currently electrified, which means that the country lags behind electrification rates in other European nations. Last year the British government scrapped electrification projects in some parts of the country, saying it would look to hybrid technology trains instead.

Rolls-Royce considering carbon coachbuilding?

There's any number of applications in which you might expect to find carbon fiber on an automobile, but a Rolls-Royce is not one of them. That could change in the near future, however, as the super-luxe auto marque is reportedly looking into using the lightweight material on a range of special models.
The idea, according to Edmunds, would be to rebody certain models in carbon fiber as a sort of in-house coachbuilding operation for discerning customers looking for something a little different from what the neighbors in the next mansion or ivory tower over have in their gold-paved driveway. While the carbon-fiber bodywork might help shave off some of the weight from a range of cars that tip the scales at 5,500 pounds or more, the principal notion here is exclusivity.
The business case for these bespoke automobiles apparently stems out of two developments. For one, the vast majority - over 90 percent - of Rolls-Royce customers opt for some manner of customization or another. For another, parent company BMW has been working hard to reduce the cost of carbon-fiber production in particular for the new i3, and that expertise could turn these premium-priced creations a greater cash cow for Rolls-Royce than the development of a sport-utility vehicle ever could.

Rolls-Royce Spectre electric coupe testing moves to sunny southern France

Rolls-Royce's first series-produced electric model is well on its way to production. Called Spectre, the big coupe is undergoing shakedown testing on and off the track in the sunny south of France, and the British firm announced that development work is about 40% complete. Going electric isn't an excuse for Rolls-Royce to stray from the reputation for excellence that it has earned over the past 116 years, so engineers are putting the Spectre through the most rigorous testing program they've ever subjected a new model to. We're told that, when all is said and done, the prototypes will have covered over 1.5 million miles of testing, which represents on average more than 400 years of use for a Rolls-Royce. Some test mules were sent to freeze in Sweden near the Arctic Circle, while others were shipped to the French Riviera. Testing in France will be split into two parts. First, the Spectre will be put through its paces on the track that Rolls-Royce parent company BMW operates in Miramas, a town located about an hour west of Marseilles. Engineers will notably get the opportunity to drive the prototypes on handling courses, on a 3.1-mile oval with steep banks, and in standing water. when they have passed every challenge with flying colors, the prototypes will be sent out to the picturesque roads that zig-zag through the countryside surrounding the test track. Rolls-Royce explained it's putting a tremendous amount of effort into fine-tuning the Spectre because the coupe packs more technology than any model it has previously released. It features "141,200 sender-receiver relations and has more than 1,000 functions and more than 25,000 sub-functions," according to the company, which is around three times more sender-receiver signals than in a typical Rolls-Royce. The Spectre will inaugurate a new suspension system that promises to take the firm's Magic Carpet Ride to the next level. It relies on technology that scopes out the road ahead and on data sent by the navigation system to decouple the anti-roll bars when needed, such as on a straight road, and recouple them as the car approaches a corner. The suspension system also gets firmer ahead of a bend. Rolls-Royce hasn't released powertrain specifications yet, and the Spectre's final design remains hidden by camouflage, but the few official numbers available are impressive.
