CO2 emissions are the biggest issue for the car industry right now, and governments around the globe are seemingly obsessed with one single gas.
Now manufacturers are rushing to play catch-up with<b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b><b></b> their petrol engine technology over diesel engine, and many are downsizing and turbocharging.
Mazda take different approach: weight reduction-a new car that's lighter than the one it replaces. Lighter weight brings emissions and economy benefits - and also helps handling and performance. It's the 21st century's must-have car accessory.
Now Mazda has released details of exactly where and how it has removed 100kg from the kerb mass.
By making the car physically smaller (40mm shorter and 55mm lower), 22kg has been lost. This is made possible by modern CAD computer design and the use of high and ultra-high tensile steels, which have the subsequent effect of making the bodyshell stronger.
Suspension changes, which include shorter rear trailing arms, have cut 13kg. Even smaller savings are important, though: different magnets in the door speakers have shaved 980g, while 690g has also been trimmed from the bonnet hinges. Shortening the wiring harness has cut 2.86kg.
