Reduced fuel consumption


Because wheels are considered un-sprung weight, additional fuel savings are realized due to mass moment of inertia, where less effort is required to rotate a forged aluminium wheel that weighs half as much as a steel wheel.

In testing performed by an independent testing and research firm, the Alcoa aluminium wheels demonstrated an improvement of 3% in tyre rolling resistance over a steel wheel. This reduction in rolling resistance translates in a fuel saving of 1.0%.
