[2] The design had a Kammback rear and a very low nose with flip-up headlights, and a large single windshield wiper.

[4] The design was originally shown as a prototype based on the front-wheel drive Autobianchi A112, and was adapted by Lombardi for the 850 sedan's floorpan.

Low drag resistance and weight (630 kg or 1,390 lb) meant that this was supposedly enough for a top speed of 160 km/h (99 mph).

[3] Later production models had the 850 Special engine, with 47 hp (35 kW) DIN at 6400 rpm - in a period German test the maximum speed of the more powerful variant was 153.8 km/h (95.6 mph).

The front suspension consists of a transverse leaf spring on the bottom and A-arms on top, while the rear received coil sprung semi-trailing arms.

[6] A Cypriot millionaire casino owner had also shown interest in the Lombardi Grand Prix around the time of its introduction.

Going on sale in 1970 it was fitted with the same down-sleeved 817 cc (49.9 cu in) version of the inline-four engine as used in federalized Fiat 850s to get beneath 50 cubic inches, thereby avoiding the need to carry emissions controls equipment.

[11] For better cooling than the original Lombardi and OTAS, Abarth mounted the cooler up front, in the air stream.

[15] Equipped with a version of the Fiat 124s 1.2 litre engine, bored out by 2.5 mm for a total of 1280 cc, this model has 75 hp (55 kW) DIN and only moderately more weight, ranging from 680 to 750 kg (1,500 to 1,650 lb) depending on the source.

[17] With the rear-mounted heavier 124 engine weight distribution has a distinct rear bias (39/61), although this seems to have had only a modest effect on handling, limited to some front-end lift at higher speeds.
