A first? BMW concept vehicle preheats transmission fluid to improve efficiency

Via GCC:

This is actually an old article; not sure why I stumbled across it.

Except I noticed in the illustration: "Solar roof for pre-warming of transmission fluid"

I wasn't sure at first if it was photovoltaics or thermal. Of course, it's PV:

The concept car also features a solar roof which acts as an additional energy source for the vehicle power supply which is independent of the engine. High-power solar cells covering a surface area of some 1.0 square meters generate a maximum energy of one kilowatt hour for consumers inside and outside the vehicle. This enables pre-heating of the gear oil, thereby shortening the inefficient warm-up phase.

The roof can contribute power to other systems too.

This is the first I've ever seen the idea of prewarming a transmission from a manufacturer.

I like how they are improving on old technology instead or inventing something new.

Seriously the ICE needs to die. It's ancient.

I know it sounds brilliant on paper but trust me. BMW always finds a complex solution to a simple problem that is guaranteed to fail on spectacular and unexpected ways. Somehow 'keep it simple stupid' never got translated into German. I know. I've owned 3 thus far. The fewer the cylinders, the more fun you have.

The internal combustion engine will outlive you by at least a century.
