SOME US CARS MADE OF ALUMINIUM THAT DON’T RUST AND WEIGH LESS, BUT COST MORE:

ACURA NSX $60 000 in 1991, $116 000 in 2020

The original everyday supercar was also the first massproduced vehicle with an aluminium body and chassis.

FORD F-150

$33 375 and up

Ford shifted its best-selling vehicle to aluminium alloy in 2015, for better towing and fuel efficiency.

TESLA MODEL S

$89 990

A lighter body helps offset the heavy batteries. The less expensive Model 3 uses steel parts.
