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.

Project MPGiata! Mods for getting 50+ MPG from a 1990 Miata
Honda mods: Ecomodding my $800 Honda Fit 5-speed beater
Mitsu mods: 70 MPG in my ecomodded, dirt cheap, 3-cylinder Mirage.
