Beneath the bright work, Encore rides on GM’s Gamma 2 platform, which it shares with the Chevrolet Trax and Tracker. The Encore GX rides on the GM’s VSS-F platform, which it shares with the Chevrolet Trailblazer. This means there is a size differential — the Encore GX rides on a 2,596-millimetre wheelbase, 41 mm longer than Encore. Likewise, GX is 78 mm longer and 33 mm wider, but it’s also 29 mm lower, which means it has 17 mm less headroom than Encore. Surprisingly, there’s little difference between the two in the amount of legroom front or rear. In terms of cargo space, the Encore GX has 665 litres with the seats upright; and 1,422L with them folded flat. The Encore has 532 L seats up and 1,371 L when folded, which is 133 L and 51 L less, respectively.
