Vehicles will be judged on aesthetics, build quality, ergonomics, fuel consumption, safety, handling, performance and value for money.
The 12 finalists (in alphabetical order) are:
Judges will put the finalists through a two-day test session in February 2013 at the Gerotek test facility, west of Pretoria.
Vehicles will be evaluated under the same conditions (except off-road capable entries will also cover a 4x4 track) on the open road, a body-twist track and a handling track at Gerotek with each model weighed for what it is - sports car, mom's taxi, family sedan etc.
Following the test sessions, a final allocation of points will be tallied before an overall winner is announced.
A significant change for the 2013 competition format was a Car of the Year workshop held earlier in 2012. The judges are also no longer compiled simply of veteran SAGMJ members; instead, each member voted for 25 of their peers to serve as a judge. The 30 members with the most votes were co-opted for evaluation duty.
While all of the models are deemed to represent examples of outstanding automotive engineering, there can be only one winner and it will be revealed in March 2013.
