In 1989, alongside the renewal of the Same Explorer, a corresponding Lamborghini model was introduced, which received the additional name Grand Prix alongside the model designations of its predecessors. The most important innovation was the hydraulic Power Speed quick-shift system, which enabled the number of gears to be 40+40. The basic transmission was now also equipped with crawling gears, totaling 20+20.

The Same Grand Prix was distinguished by a water-cooled engine with a displacement of 4.0 liters. The increase in torque was 23% and 26%, and in the turbocharged 90 model, 31%. The power take-off speeds were 540, 750, 1000, and 1250 rpm, as well as a road power take-off. The operation of the PTO was electro-hydraulic. The Grand Prix 80 and 90 models featured an auxiliary cylinder for the lifting device, resulting in a lifting capacity of 4760 kg.

The cabin was a narrow model similar to its predecessor, with a reported noise level of 80 dB, clearly lower than that of the Same. The shape of the engine hood was still the traditional Lamborghini style, tapering downwards, unlike the green Hürlimanns, whose shape corresponded much more closely to the Same Explorer. The Hürlimann lineup also included the H 358 Prestige, a 3-cylinder equivalent to the Explorer 60, but its engine was water-cooled. The 4-cylinder Hürlimann models were designated H 468, 478, and 488T Prestige.
