The 2013 Honda Accord, due to go on sale in the US on 19 September, features the first use of a new Honda-developed catalyst which significantly reduces the precious metals required in catalysts for emissions aftertreatment. The new catalyst enhances the performance of palladium, also allowing a reduction in rhodium use.
