BMWs new concept car.....vid..



part 2
http://www.youtube.com/watch?v=T_CqN...eature=channel

Car will feature futuristic design in a 2+2 seating arrangement
-- diesel electric hybrid engine with high performance hybrid drivetrain

-- powered by 3-cylinder diesel engine with two electric motors

-- power output ~350hp (which together with its lightweight contruction
will be as fast as BMW's current M3 as as fuel efficient as a Prius)

-- can run on either diesel engine or electric motors alone, or a
combination

-- battery can be partially charged through regenerative braking or fully
charged via plugin to standard outlet.

What's the sticker, I'd imagine over 75k if they ever built it...

Still very pie in the sky, but this is how it starts. Great to see some of the concept looks.

One very cool potential of future cars if they contiune down the electric route is the TQ numbers that will come out of some of the designs.

Electric motors have an insane potential for bone shattering TQ. The mechanic of the future (50 years from now) will need a damn EE degree though...

Glorified Chevy Volt copy. The concept of using an ICE to recharge the batteries was GMs. Everybody is now running like hell to do the same thing, the Japs, Krauts, and the rest of the multicultural car market pirates.

I repair electric material handling equipment that used DC motor controls along with some of the newer equipment that have a DC battery and an inverter to run brushless AC motors.

I think it's just going to require a new line of thought for today's technicians.

The part that runs the motors and controls their speed are usually a "black box" that is a serviced as a unit and rarely fail, then you have various sensors that tell it what to do and when to do it. These can be monitored thru a scan tool or computer program. Often, the black box has self diagnostics built into it and it tells you what is wrong. The box can also handle the turning the motors into generators when braking to help recharge the battery.

The part I struggled with the most when I came from a 15 year automotive backround is realizing there is no ground, only positive and negative connections to make the motors run and change direction.

Electric motors make the most torque at zero rpm and are most efficient at their highest rpm.

This technology has been in use for at least 50 years now, it's the advancements in battery design and engine management that has made it practical for automotive use.
