I just love the Mazda3

Very nice video of optimization.

nice aerodynamics! now it can go 50 km/h in the city even faster!

@strapinhotpockets

Improving aerodynamics means that for the same speed, the more aerodynamic vehicle will require less power and use less fuel. Redesigning bodywork is considerably cheaper than redesigning engines and drivetrain yet can reap greater efficiency gains.

That's because of the square cube law. To double the speed of a vehicle the drag goes up by the square but the power required goes up by the cube. 8 times more power!

For a set speed, Halve the drag, 4times less power is required

I don't think it was necessary to make the car ugly (huge smile face on front end) in order to improve aerodynamics. I still like the car though.

I love how this video shows the design evolution of the Mazda3. Cool music too!

Look, they turned the red squigglies blue!

The video is extremely well put together ;)

[FLLMTR]

Really neat. Too bad it isn't on the U.S. Mazda website. It should be.

[chrisfll]

Pretty cool.

it kinda looks like the old and elow ACURA MDX

come on u could design better than that

[pbcmbeez22]

@moepsp the MDX is an SUV...this is a sedan. they are NOTHING alike

[togi93ab]

Brilliant design!
