The Agades was a concept vehicle developed by the French coachbuilder Heuliez, presented as a small four-wheel-drive passenger car with genuine off-road capability. It measured 320 cm in length, 166 cm in width and 153 cm in height, with a wheelbase of 204 cm and front/rear track widths of 144/142 cm. Ground clearance was adjustable between 10 and 30 cm, and the short front and rear overhangs gave approach and departure angles of 45 and 50 degrees respectively. Its proportions were compared to the Suzuki SJ Samurai, though unlike that pure off-roader, the Agades carried a compact but well-proportioned passenger-car body, making it smaller and more refined in appearance than a Lada Niva.
Its front-end styling was derived from the Peugeot 405 and carried Peugeot badging, though the bumper and integrated front skirt were shaped differently, and all other body panels were newly designed. Power came from a Peugeot XU9 2C four-cylinder engine of 1905 cc producing around 105 hp at 5600 rpm and 155 Nm of torque at 3000 rpm, driving all four wheels through a five-speed gearbox with a short first gear and an electromechanically locking central differential. Suspension was hydropneumatic, with independent rear suspension, disc brakes and a differential brake. It rode on 215 R 14 XCM+S4 off-road tyres. The four-seat interior used denim fabric and leather trim, with long doors allowing easy rear access, and a tailgate opening onto a compact boot.
