We’re not the type to be easily surprised by anything that happens in the auto industry, but this one really caught us off-guard - in a good way, of course.

This here is a new lightweight BMW X5 prototype that, according to BMW, is about 50% lighter than the weight of the first ever X5 to be released to the public some years ago. The material in use for this prototype is something that’s called carbon fiber reinforced plastic, a material that supposedly cuts the overall bulk of cars without compromising any of the safety standards set on these vehicles.

That potential alone should make the hairs on the back of our heads rise without provocation.

In addition to its lightweight nature – and the fact that nothing is taken away as far as safety is concerned, the CFRP can also provide stability to a vehicle in inclement conditions while providing the necessary sturdiness to absorb any potential hits without debilitating damage.

All in all, this X5 prototype, by using the CFRP material, saves as much as 400 pounds from other X5s that use steel on the body. It may not look a lot to the casual observer, but 400 pounds less means less weight to pull around. And you don’t need to tell us how that affects the power and speed of a car.

Wow! So its really possible to put a carbon fiber material in the body of the car. For sure, this car would be lighter they should make it a sports car instead!

hmm. I don’t like the huge body concept for this car its kind of distracted. However, just recently, BMW X5 has been released, and the specification is good plus the outstanding engine performance.

It looks a lot better moving around than standing still......I don’t hate it anymore, but it’s way ugly none the less, I hate the rear bumper and I really hate the fact that the front bumper is interrupted by the grill. At very least they kept the grill attached to the hood, other than that I hate it. It looks funny, the 3rd row looks like a novelty, it doesn’t look very functional at all. Have you ever been inside the Nissan armada? Nissan really thought about the functionality of the third row. BMW did not. It looks like a bloated X3....whats the difference between the X3 and X5 now, a 3rd row....a terrible 3rd row at that. And what is with with these soulless barren deco, novelty interiors that BMW is putting in their cars now? it makes me so sad because they used to have great driver oriented interiors that wrapped around you and hugged you like a loving
mother. I used to love you BMW.

I would like to leave is that although it’s the first time I’ve seen the new X5 in action thus making the video instantly cool, it would have been a more entertaining experience to hear some commentary in addition to the background noises of the car and environment. It was just too boring after the first minute, and for the last 8 minutes, I pretty much tuned out... Maybe the specs, with some nuggets of car geek information from the BMW press release. I don’t know, anything to keep the viewer a little more engaged than just the car going through motions. Just my 2 cents.

Only the doors are made out of steel, and one can see the weave pattern when the door frames and structural ars are examined.

I think BMW is years ahead of the competition when it comes to materials research & supply/manufacturing process. We will see more magnesium components and carbon components in their mainstream lineup, where other manufacturer will be playing catch up.

They are investing in plants to mass produce this stuff. Makes perfect sense and is a smart move.

The body-in-white monocoque without any other bodywork was 400 kilos, now 200 kilos, or two fat blokes, well done indeed.

do this came in package or is it just an optional.

good, carbon kits can lessen the x5’s weight. with that, it can lessen the fuel consumption and it can accelerate faster than a regular X5.
