In the mid-90s it was customary to differentiate the different body variants of the same model by inserting two cars with different names in the price list. Fiat had done it with the Bravo and Brava models from 1995 to 2002 but also Alfa Romeo with 145 and 146. Today our attention is focused precisely on the two compact sedans of the Arese company, as similar in mechanics and in the design of the front up to the B-pillar, as different in the rear.
The first, designed in the Fiat Style Center by Chris Bangle and presented in 1994 at the Turin Motor Show, was characterized by a 2-volume and 3-door body while the second, a sedan with a 2 and a half volume body with 5 doors. designed by Walter de Silva of the Alfa Romeo Style Center, it was officially shown for the first time during the 1995 Geneva Motor Show.
The two sedans of the Arese company, heirs of the iconic Alfa Romeo 33, were born on the Fiat Tipo 2 platform. In addition to the unibody structure that united the chassis, the underbody and the body of the vehicle in a single structure, the 145 and 146 could count on McPherson type suspension at the front and multi-link suspension at the rear. The steering, equipped with hydraulic power steering, was rack and pinion.
One of the most important advantages in using this platform was represented by the fact that it allowed the thrusters to be positioned both in a longitudinal and transverse position. The first allowed the installation of Boxer engines which were mounted in the same configuration used on the Alfa 33 or Alfasud, while the second was used for the Twin Spark diesel and petrol engines. The powertrain was completed in all versions by a 5-speed manual transmission.
Boxer engines available
Despite their market launch within a year of each other, the engine range of the 145 and 146 was identical. The customers of the Casa del Biscione could choose between a 1.9-liter 4-cylinder turbo diesel and three gasoline engines of the boxer type with opposed cylinders, derived from those seen on the previous Alfa 33: a 1.4 and a 1.6 with single camshaft overhead and 2 valves per cylinder that guaranteed a maximum power of 90 and 103 hp respectively. To these was added a 1.7 16-valve with double overhead camshaft of 129 HP.
Farewell to boxers with the ’97 restyling
In January 1997, the two models underwent a major upgrade to the engine range that closed the boxer chapter for Alfa Romeo forever. The three opposing cylinder units, in fact, were replaced by the 1.4, 1.6 and 1.8 liter Twin Spark 16 V petrol engines capable of delivering 103, 120 and 140 hp respectively. The restyling also brought with it numerous innovations in the passenger compartment and exterior design, including a new air conditioning system, a dashboard with a renewed design, new wheel covers and alloy wheels.
The latest restyling and the arrival of the 147
Before being withdrawn from the market in 2000, leaving room for the successful Alfa 147, the 145 and 146 underwent a final late-career update in March 1999 that led to the replacement of the 1.9 turbodiesel with the new 1.9 JTD common rail direct injection turbodiesel. from 105 hp. Among the aesthetic innovations, the most significant were represented by the introduction of bumpers in the same color as the body with round fog lights and chrome interior finishes.
