This car is also known as the Alfa Romeo AR 146 "Magnagona"
In 1981 the engineer Magnaghi was contracted to design an off-road vehicle to be made in both civilian and military versions.
Two versions of the 146 -with wheelbase of 235 cm and 275 cm - were planned with a load capacity of about 1000 kg. It had a load-bearing chassis and bolted-on framework, rear-wheel drive, with optional four-wheel drive, five standard plus reduced gears, a fully laden weight of approx. 1750 kg and maximum tilt of 60%. The axis are rigid and mounted on leaf springs, steering is power-assisted, disk brakes at the front and drum brakes at the rear. A civilian work version (the puzzle car) was also made, as a modified version of the military "torpedo". 5 versions based on standard vehicles were planned: 2 VM 4 cilinder 2400 cc diesels (normally aspired and turbocharged) and 3 normally aspired versions running on petrol - 2 with 2000 cc a 4-cylinder and a V6) and a 3000 cc V6. Oto-Melara, also a part of Finmeccanica group (like ALfa Romeo back then) provided the transmissions.
