The outright SUV lap record on the ‘ring is held by the Audi RSQ8 at 7:36.7. The gravity weighs 600 lbs more but makes nearly 200 more hp for a 15% better power to weight ratio. Otherwise the cars have nearly identical wheelbase, width and length, though the Gravity is a couple inches lower. The Gravity will have a much lower CG, better rubber (PZ5 vs PZ4) and should at least match the Audi’s rear wheel steering, active roll control, torque vectoring, etc. The only obvious reason the Gravity GT wouldn’t take the SUV ‘ring lap record is inadequate thermal management, which over a lap I feel sure they can handle…
You don’t send a small fleet across the world purely for tuning reasons. I’d expect forthcoming lap records for the Gravity GT and/ or the Dream Edition.
