Good question shhan. I also think that it is a wasting of resources unless it is a raze.

True shehan for me also mileage is important than the horsepower.

Naperlou, while the bigger cars are lighter than the 70's, pickups and the small ones certainly are not being rare at under 3k lbs now for even subcompacts.  Try to find a pickup under 4k lbs?  Vs the under 2k lb  for both compact cars and mini pickups then that got 30-49 mpg.

Plus most were more aero driven in reverse!!

The Tesla shows the power, performance and eff of EV's.  I do agree it is too heavy but it seats 7!!   Not a small car.  I don't see much good in most EV's having over 80-100 mile range as you just drag a lot of weight you never use.  Instead a tiny 4-20kw generator for unlimited range makes both a lighter, lower cost, more flexible EV.

While Alum is lighter than steel, not by much, maybe 10 percent .  It's big thing is cheaper production line and doesn't rust.   To get an actual lighter, lower cost, more eff  vehicle one has to go composites dropping the weight 40 percent, thus batteries, etc cost by 40 percent.

Hopefully by summer I'll be doing an all composite sixty four split window Corvette  body/chassis this way with Miata racing suspension coming in under 2,000lbs if I can get the money up. Already have the molds ready.  I'd like to do a series of 10 of them to show just how fast, cool all composite EV's can be. 

But the one thing to be said is the E motor is the eff one of the future can't be ignored for cars and even trucks because it almost always runs eff. Vs iCE's that rarely are.

shehan, I do not disagree, I am just pointing out that Detroit suffered a huge image problem in the late 70's and through the 1980's while Japan was actually making improvements to their cars in terms of MPG and precieved power. With this in mind, I think Detroit is sticking with V8 power and making their smaller engines as robust as possible. They want to avoid the crappy image they had.

@Charles – Most European car manufacturers don't take fuel consumption seriously, I've heard almost all Chystlers consume much fuel than an ordinary Asian car. What do you think of the German cars?

@GTOlover – I would be happy if this fuel consumption was for a truck as it carries much payload, but for a car a V6 or V8 engine is just a waste.

@William – yes some of the owners care about fuel and some really don't, but do we really need to waste our resources. What's the difference in using a car with less horsepower.

@lynnbr2 -Most of the younger generation today wants power and torque hence they go for vehicles with higher engines.

@Zippy – we don't need much horsepower for day to day traveling as I always say. Horsepower is needed for racing and off-road journeys.

Sometimes I feel it's the customer's duty too to make the right choice. Why do you want to select a higher horsepower vehicle with less MPG when you can go for a hybrid vehicle.
