Aluminum receives good marks as a lightweight material in existing models, including the best-selling Ford F-150 as well as models from Jaguar Land Rover. And every aluminum car and truck crash tested in the US has earned a 5-star safety rating as consumers indicate they like these vehicles’ fuel economy, durability, safety and overall performance.
