The GAC Grampus A is a medium‑to‑large utility pickup built with a tough, powerful and imposing appearance. It adopts a streamlined low‑drag body design with a drag coefficient below 0.4, fitted with integrated headlights, side‑mirror‑mounted turn‑signal indicators as well as front and rear fog lights. Available exterior paint colours include Black, White, Red, Blue and Silver.

In terms of dimensions, the double‑cab standard‑bed variant measures 5,330 mm in length, 1,870 mm in width and 1,864 mm in height, with a wheelbase of 3,100 mm. The long‑bed double‑cab version stretches to 5,730 mm long while keeping the same width and height, paired with a 3,513 mm wheelbase. Its large‑volume pickup bed reaches 1.61 m³, delivering 20 percent greater loading volume than conventional utility pickups and supporting payloads over 750 kg. The truck comes factory‑equipped with external cargo hooks, spray‑in bed liner and roll cage.

The GAC Grampus A features a black‑toned interior, fitted with premium ergonomic leather seats to deliver solid support and long‑journey comfort. High‑contact areas are covered with leather and soft slush‑moulded materials, complemented by piano‑black lacquer on the centre console. The door sill height stands at only 560 mm; side steps plus grab handles enable easy cabin access.

It is equipped with an eight‑speaker audio system and a standard 9‑inch touchscreen infotainment unit integrating radio, Bluetooth, navigation and hands‑free calling functions, alongside USB ports and a standard reversing camera. The driver gets a four‑way manually adjustable seat while the passenger seat also supports four‑way manual adjustment. Other practical configurations cover multifunction steering wheel, key‑fob central locking, manual air‑conditioning, dual hood‑lift gas struts, front disc‑and‑rear‑drum brakes, hydraulic power steering, plus ABS and EBD for active safety.

The GAC Grampus A offers three engine selections: the Mitsubishi 4G69 2.4‑litre gasoline engine (100 kW peak power, 200 N·m peak torque), the Mitsubishi 4K22 gasoline unit (160 kW peak power, 320 N·m peak torque), and the Yunnei D20T diesel engine generating 110 kW and 350 N·m. The Yunnei D20T diesel motor uses a Bosch high‑pressure common‑rail fuel‑injection system and Honeywell turbocharger; it achieves fuel consumption of 8.3 L/100 km and can run 400 000 km without major overhaul, with low‑end torque optimised for climbing capability.

Transmission choices cover 5‑speed manual, 6‑speed manual and 6‑speed automatic. It supports rear‑wheel drive or part‑time all‑wheel drive with rear differential lock. The chassis uses a variable‑section trapezoidal frame with two longitudinal and nine cross members. A widened double‑wishbone front suspension matches reinforced 3+2 variable‑stiffness rear leaf‑spring suspension, delivering a one‑ton load‑bearing capacity, while the powertrain transmission efficiency can hit up to 98 percent.
