Alfa Romeo 156 - Development

Development

At the beginning the engine range encompassed four cylinder Twin Spark (1.6 L 120 PS (88 kW), 1.8 L 144 PS (106 kW) and 2.0 L 155 PS (114 kW)) 16 valve engines with variable valve timing, along with the straight-4 1.9 litre 8-valve 105 PS (77 kW) and straight-5 2.4 litre 10-valve 136 PS (100 kW) JTD common rail turbodiesel engines. Until January 2002, the range-topping engine was the venerable double overhead camshaft 2.5 litre 24-valve Alfa Romeo V6 engine rated at 190 PS (140 kW).

Initially the 156 range was available with different options (packs) like a sport pack that could include either Blitz clothing, Momo leather interior or Recaro seats, it also included 16-inch (410 mm) wheels, lowered suspension and leather steering wheel and gear knob. There was also available De-Luxe pack with Momo's mahogany steering wheel and gear knob and for Nordic countries special winter pack consisting of fog lights, headlight washers and heated seats.

Starting from 1999 five-speed Selespeed sequential transmission came as an option to 2.0 litre Twin Spark version and four-speed automatic Q-System to 2.5 litre V6 version, the Q-system can be used as normal automatic or shift manually with H-pattern, it has three automatic modes: city, sport and ice.

A significant addition to the 156 range was the Sportwagon estate in 2000, a first attempt at an estate car of this size for the company. Sportwagon was also available with Boge-Nivomat self-levelling hydropneumatic rear suspension. The Sportwagon was marketed as lifestyle estate without large carrying capacity. The Sportwagon bodystyle filled a gap in the market that Alfa Romeo had distanced themselves from since the 33 SportWagon of the 1980s.

In 2001 engines were upgraded, engines complied with Euro3 norm and outputed 120 PS (88 kW) (1.6 L), 140 PS (100 kW) (1.8 L), 150 PS (110 kW) (2.0 L) and 192 PS (141 kW) (2.5 L).
