The Grandstar is a front-wheel-drive minivan in the mould of an early-2000s Dodge Caravan. It is heavy, very nose-heavy (around 58–60% on the front) and it sits tall, so it carries a high centre of gravity. That combination gives it strong understeer and a real tendency to lean and tip — but it also gives it mass, which on a demolition track is a weapon.
How it drives
The Grandstar pushes. All that weight over the front, plus front tyres asked to steer and drive at once, means it understeers hard if you carry too much speed in or get greedy with the throttle on exit. As with any FWD car the answer is to rotate it early — lift off or trail-brake into the corner to bring the light-ish rear round and point the nose before you get back on power. The difference here is that the tall body works against you: lean into a corner too aggressively and the high centre of gravity has it rolling, and it will tip if you provoke it. Smooth, deliberate inputs keep it flat and pointed.
Pace comes from stability, not agility. You are never going to flick this thing through a chicane; you drive it tidily, brake in good time, and let its rotation do just enough to get it turned.
In a pack the Grandstar is in its element. It is heavy and it hits hard — use the mass as a ramming asset, lean on smaller cars and let contact do work that cornering never will. Where a light FWD car survives by dodging, the Grandstar survives by weighing more than the thing that hit it.
