By the time the R5 comes out, the battery pack that powers the car will have been made from a new material that’s significantly lighter than the old lithium-ion batteries.

The R5’s new battery pack is designed to provide more energy density, but the car’s batteries will still last more than 30 years, the carmaker says.

The battery pack, made of the same material as those used in smartphones and laptops, has been designed by a team of engineers at the University of Michigan and the University to be lighter than traditional batteries, allowing for greater energy density and less noise.

The new battery design is made from aluminum alloy that’s a fraction of the weight of conventional lithium-air batteries.

The alloy is also lighter than lithium, making it ideal for powering electronic devices that require high power and high efficiency.

“It’s basically the equivalent of the materials we’ve been using for years in our smartphones and tablets,” said R5 senior engineer Dan Stempel.

“We’re using aluminum alloy to make it lighter and more efficient than the lithium-ions.”

The new materials are manufactured in the United States at a facility in Ann Arbor, Michigan.

The R5 has an internal combustion engine, which is what powers the R4, and an electric motor, which powers the next generation of R4s.

The lithium-ionic battery is used in the R3, R5, and R6 models of the R6.

These cars are made with the lithium ion battery.

The lightweight aluminum alloy will also be used in future R5 and R5 Plus cars.

The company is also working on developing a lithium-manganese battery that will be more efficient and lighter than conventional batteries.

A similar lithium-polymer battery is also being developed for the R7.
