General
Predecessor to the Alfa 155 is the Alfa 75 In contrast to the rear-drive Alfa 75 Alfa 155 has front wheel drive with transverse engine. The only exception is the Q4 version, which is four-wheel driven like the race car and a four-cylinder in-line engine with turbocharger has. The Alfa 155 shares its platform with its consolidated brothers, depending on model and engine came in the following vehicles have the same or revised in detail so-called Tipo Group platform used:

Model history
In January 1992, the Alfa 155 came with two four-cylinder Twin Spark engines (1.8 L and 95 kW/129 hp and 106 kW/144 hp and 2.0 liter and a 2.5 - liter six-cylinder with 121 kW / 165 PS) on the market. The 155 Q4 was permanent all-wheel drive, three differentials ( normally on the front axle, epicyclically including a Ferguson viscous coupling in the center, self-locking Torsen differential on the rear axle ) and a 2.0-liter 16V four-cylinder turbo engine with 190 hp.
In April 1993, the introduction of a smaller twin -spark engine with 1.7 liter displacement and 85 kW (116 hp) and two turbo diesels started with 66 and 92 kW ( 90 and 125 hp ), also the passive safety has been increased.
After three years a minor facelift was carried out in March 1995, the fender flares and a modified front included. Also new is a 2.0 -liter 16V Twin Spark was controlled with variable intake camshaft and 110 kW ( 150 hp).

Motors
At the start of series production of the Alfa 155 was equipped with engines that were derived from the classic Alfa- Vierylinder. These motors are characterized by chain-driven camshafts, two valves per cylinder and an aluminum-made engine block. THe engines possessed cylinder heads with dual ignition, hence the name " Twin Spark " that to which the racing engines of the 1970s were inspired and had a narrower valve angle than the classic Alfa engine. One exception was the 155Q4 whose drive mechanism was completely taken over by the Lancia Integrale and therefore had a turbocharged four-cylinder Fiat Lampredi with toothed belt drive. Later, the Alfa 155 was equipped with the engines of Fiat's " modular " construction series were derived. They had an engine block made of cast iron gear belt driven camshafts, four valves per cylinder and twin ignition. In contrast to the previously installed Alfa engines spark plugs were of different sizes in these engines and ignited simultaneously. Rather, the smaller, laterally screwed candle lit in the exhaust stroke of the engine in order to improve the exhaust emissions.
The 155 motor sports
After a successful first season in 1992, in which the racers Alessandro Nannini and Nicola Larini won confidently on a equipped with 2- liter turbocharged four-cylinder 155, the Italian Touring Car Championship, was the first 155, now with a V6 engine, from 1993 in the German touring Car Championship DTM used. Larini won the championship here right away and laid the foundation for a long-lasting, highly successful career of 155 in motorsport.
