In a dyno test, three Lamborghini models – the Aventador SVJ, Huracán STO, and Urus Performante – were measured for actual power output and weight to determine their true power-to-weight ratios. The STO produced 550 wheel horsepower (whp), slightly under its claimed 640 hp. The Urus Performante exceeded expectations with 704 hp, while the SVJ also surpassed its claim with 809 hp. However, all models were heavier than claimed, affecting their power-to-weight ratios. The SVJ was particularly overweight by 220 kg, resulting in a power-to-weight ratio of 439 hp/ton, compared to the claimed 472 hp/ton.
