Dr Edwin Pang
The Discoverer Stronghold AT distinguishes itself with superior snow handling and ice acceleration, appealing to drivers who prioritise winter agility and traction.
The Discoverer Rugged Trek delivers competitive dry balance and a more aggressive all-terrain positioning, although it trails in braking metrics here. It is also important to note that dedicated off-road testing was not included in this comparison, which could potentially be a key strength of the Rugged Trek given its more rugged design intent.
