BMW's Green Supercar Revealed

Posted February 04, 2009 10:18 AM

From INHABITAT:

The race for the green supercar is on, and BMW is itching to become a key player. In a push to roll out a green vehicle, BMW recently revealed the BMW Z10 ED, a ultra-efficient 400 horsepower hybrid that the company hopes will become their new flagship vehicle. The focus of the Z10 Efficient Dynamics vehicle is on technology to reduce its carbon emissions. Instead of an electric motor, BMW is experimenting with increasing the efficiency of the motor. A new high-pressure turbocharged engine will replace the current 3.0 litre unit. According to BMW, the advances in technology mean that petrol engines can be manufactured to run much more efficiently, but provide the same amount of power as that of a conventional engine.

Hmmm, yes, and how efficient could they be if they didn't insist on producing a ludicrous amount of power?
400hp....ooooh yes we all really need that much power.

1 hp used to be sufficient to move the average "Joe" around, all right with the vehicle under our buds maybe 8-10,

therefore 1/40th would be sufficient.

Del, I just don`t see BMW using an ad campaign advertising a 40 hp vehicle, remember that you are not using all of the hp all the time, if you were the engine would be toast very soon.

OK 120 if you add the family and a load of groceries, just have to rename the car MWB (might work better), on second thought BMW sounds better.

As long as the gas mileage is not affected negatively, who cares if there were 600 hp, just go easy on the accelerator!

I do take your point ..but a 400hp engine must by necessity be heavier than a 40hp one or a 100 hp one...thus it must be wasting energy.
You don't need all those horses to get the performance either..that's why they invented gearboxes.

Lose the weight, half the hp at least.

OK, so if we lose the weight of the gear boxes, the additional HP will make up for it?

You missunderstand me.

I mean you might need 400hp if you didn't have a gearbox in order to get sufficient power/torque to the wheels over the necessary rev range.
With a gear box you can transmit enough power or torque to the wheels with a much smaller engine.
The average 1500cc engined medium sized car today can out perform the racing cars of my youth in handling, speed & acceleration.
