"The real reason is that carmakers want to go up market and sell bigger, more luxurious cars and make more profit. And heavy cars use more fuel." (http://news.bbc.co.uk/1/hi/business/7387432.stm)

Formula One Car and Driver

And we have weight choices today too! A 2,400 # compact is usually far more fuel efficient than a 3,300 # midsize ... -- Ed.

The motor car has been with us for a little over a century - ushering in an era of personal mobility that would have been inconceivable to our ancestors.

Yet now the car as we know it is under threat as never before. Rising fuel costs and mounting environmental pressures mean its long-term prospects are increasingly uncertain.

One man who thinks the motor industry faces a very bleak future indeed is the renowned engineer, Professor Gordon Murray.

"If we don't do anything, we're going to have restricted use of our cars very soon, within the next ten to fifteen years," he says.

Weight equals profit

Professor Murray designed some of the most successful Formula One cars ever built - as well as the McLaren F1, for years the world's fastest road going car.

But now, he has left the high-octane world behind and turned his attention to making the motor car more environmentally friendly… http://news.bbc.co.uk/1/hi/business/7387432.stm

Professor Murray is onto something with the weight thing. I used to install, maintain, and tune servo drives which are used on manufacturing machinery. The drive allowed you to look at the KWHr usage in chart form during it's commanded moves. By far and away, most of the power usage was during acceleration. And, as the weight of the machinery parts change, the power usage changed drastically.

Faithful and True.
