The Alfa Romeo 156 (known internally as the type 932) is a compact executive car introduced by Italian automaker Alfa Romeo at the 1997 Frankfurt Motor Show[4] as the replacement for the Alfa Romeo 155. Cars were assembled at Fiat Group factory in Pomigliano d'Arco, Italy and General Motors facility in Rayong[1], Thailand (production in Thailand started March 2002 and lasted couple of years, cars were targeted for Asia Pacific markets[5]). Between 1997 and 2005, 680,000 examples of the 156 were produced,[6] a huge success for the brand.

The 156 was available in saloon and estate 'Sportwagon' bodystyles with seven engine configurations and it went through two facelifts, first in 2002 and second in 2003.

The 156 saloon was discontinued late in 2005 in Europe, the four-wheel drive Q4 Crosswagon was produced to the end of 2007.[7][8] The 156 was replaced with 159, which also spawned the Brera, the 2-door coupe that replaces the Alfa Romeo GTV along with its convertible sister the new Spider.

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 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.[1]

156 Sportwagon

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,[9] the Q-system can be used as normal automatic or shift manually with H-pattern,[3] 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.[10] The Sportwagon was marketed as lifestyle estate without large carrying capacity.[11]

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).

Exterior styling

The 156 was designed by Alfa Centro Stile under control of head designer Walter de'Silva.[12] Its distinctive style with its high curved flanks, retro styled front door handles, hidden rear door handles, dramatic deep grille and sweeping profile made it, to some, the best looking car in its class.[13] The car was one of the first saloons to feature hidden rear door handles and prominent front door handles to give it a coupé look. The design was influenced by three historical Alfa Romeo models: the 1900, the Giulietta and the Giulia.[14] The 156 achieved a drag coefficient (Cd) of 0.31.[1] The sportwagon bodystyle filled a gap in the market that Alfa Romeo had distanced themselves from since the 33 SportWagon of the 1980s. The 156 Sportwagon was released to much critical acclaim, being one of the best, if not one of the most spacious estate cars available. Oddly enough, the 156 saloon has more luggage space than the sportwagon.[15] It can be seen the sportwagon is a hatchback version of the 156 with much better access to storage. Other differences included a lower ride height, side skirts as standard and a factory spoiler. Walter de'Silva has commented the design of the 156 as:

perfectly balanced. [12]

Interior styling

The 1998 original interior builds on a benchmark set by Alfa Romeo in their previously released Alfa Romeo 166, with a deeply scalloped upper dashboard and simple centre console. All of the main controls and displays are angled towards the driver in typical Italian sports car style, although this can sometimes be awkward for passengers who will struggle to see the interior clock. Despite being a family car, the interior design lacks cup holders, which normally come standard in saloons. Typically, for a smaller executive car, there is ample room up front for the driver and passenger to sit comfortably, with very comfortable seats. However, rear seat passengers may find the design restrictive in overall room. The 156 is a car for four people, rather than five, although later models did add a full centre seatbelt in place of the lap belt in earlier models.

2002 saw an update to both the interior and exterior of the 156.

Platform and suspension

The 156 uses a platform derived from the Alfa Romeo 155, which in turn was derived from the Fiat Group's "Tipo" platform. However it is sufficiently different from the original "Tipo" one to be seen as a new platform.[16][17] The 156 is a highly-developed front-wheel drive car; (the Cross/Sportwagon Q4 offered four-wheel drive in left-hand drive markets) with a double high wishbone front suspension and all independent multi-link rear suspension,[1][18]which consists of a telescopic vertical strut with coaxial spring and two transverse links of different lengths and a longitudinal strut. This structure means that the rear wheels have a small passive steering ability.[10] Weight saving material (aluminum) has been used in several parts both front and rear suspension. The weight saving materials was also used in many other parts like magnesium framed front seats.[19]

Facelifts

2002 also saw the arrival of a facelifted interior with different matte-finish surfacing and chrome highlights. New version used the 147's dual-zone digital climate control and CanBus serial wiring system, the interior climate could also be controlled via air quality sensor.[20]A different choice of colours were available for the interior, with the option of a two-tone interior very much like that BMW were introducing at the time. A wider range of options including xenon lighting, tele-informatics (CONNECT and CONNECT NAV) and a Bose stereo system were available, the stereo system could now also be operated via buttons on the steering wheel. Also the Selespeed gearbox control system was updated, buttons at steering wheel were replaced by paddle shifters, like seen earlier on Alfa Romeo 147. In the center console was added multifunctional display with trip computer, fault and service monitor. Also electronic stability control VDC (Vehicle Dynamic Control) and slip control ASR (Anti Slip Regulation) came as standard. Passive safety was also made better, all versions got window airbags as standard. The 2.0 L JTS 165 PS (121 kW) gasoline direct injection engine replaced the 2.0 litre Twin Spark engine, offering more low end torque and more power than the Twin Spark, diesel engines were also uprated. Only notable difference exterior-wise was a body colored mirrors and bumper strips which were earlier black.

2003 facelift (2nd series)

Late 2003 saw the launch of a facelifted 156, with new front and rear fascias designed by Giorgetto Giugiaro.[21] To the top of range was added new TI trim level (Turismo Internazionale) designating a sporty kit, this version was equipped with modified suspension, bigger wheels (215/45 17") and leather-trimmed interior. This mid-life facelift divided opinion with some preferring the prettier pre-facelift look with others singing the praises of the newer more aggressive demeanour of the latter models. The GTA models never received the exterior update. Diesel engines underwent a major re-working, new four valve per cylinder heads were added, second stage common rail injection with 1400 bar maximum injection pressure with up to five injections per cycle for lower noise, consumption and higher performance. They were rated at 140/150 PS (103/110 kW) for straight-4 1.9 litre 16-valve and 175 PS (129 kW) for straight-5 2.4 litre 20-valve.

2004 Q4 variants

In 2004, Q4 (short for Quadrifoglio 4) four-wheel drive versions arrived to some markets, which were known as the Crosswagon Q4 and Sportwagon Q4 (both using the 1.9 L 150 PS (110 kW) JTD diesel engine). These cars were equipped with a Torsen C four-wheel drive system and raised ride heights (Crosswagon height: 1,497 mm (58.9 in), Sportwagon 1,458 mm (57.4 in).[22] The Crosswagon version was made to look more like all-terrain vehicle; door sill aluminium protection, front and rear bumpers were equipped with aluminium inserts. The Sportwagon Q4 was a normal looking version with just slighly higher ground clearance than the front wheel drive Sportwagon.

GTA version

In September 2001, the 156 GTA and Sportwagon GTA were launched at the Frankfurt Motor Show. The GTA was named after the Alfa Romeo GTA from the 1960s, the letters GTA meaning Gran Turismo Alleggerita (English: lightened Grand Tourer). Even though the name suggests a light car, the GTA isn't any lighter than base 156. It was actually 91 kilograms (200 lb) heavier than 2.5 litre V6 engined version.[23] With its 3.2 litre engine its easy to get very varying fuel consumption figures, the EC urban fuel consumption is 15.6 miles per imperial gallon (18.1 L/100 km/13.0 mpg-US) and combined 23.3 mpg-imp (12.1 L/100 km/19.4 mpg-US), extra-urban consumption is 32.8 mpg-imp (8.61 L/100 km/27.3 mpg-US).[24]

The very first GTA was sold on-line auction from September 13 to 23, the duration of the Frankfurt Motor Show. Winning bid was 48,691.26 euros, which was donated to "Telethon" charity fund.[25] Equipped with a 3.2 litre V6 with six-speed manual transmission or six-speed Selespeed (paddles in steering wheel, hydraulically operated clutchless manual gearbox), the GTA variants were aimed at the performance market. The GTA variants boasted 250 PS (180 kW), had a lowered and stiffened suspension, a distinctive body kit and leather interior. The suspension was specifically made for the GTA by Fiat Research Centre and Fiat Auto Design and Development Department.[26] Steering was also made faster, only 1.7 turns from lock to lock compared to 2.1 in normal models. The GTA had also much bigger brakes (Brembo), at front 305 millimetres (12 in) discs and rear 276 millimetres (10.8 in). The front discs were later updated to 330 millimetres (13 in). The GTA subsequently stopped production in October 2005 citing the upcoming replacement to the 156, the Alfa Romeo 159.

Engines

The 156 offered various engines and power levels during its lifespan, four and six cylinder petrol engines and four and five cylinder diesel engines, all produced at Pratola Serra except the V6 engine , which was produced at Alfa Romeo's Arese plant.[1] [27][28][29][30] The 1.9 JTD diesel was world's first common rail diesel engine in a passenger car.[31]

The Alfa Romeo 156 was as well vested in motorsport as its predecessor, the 155. It runs in the British Touring Car Championship as well as various European championships, most notably the WTCC and formerly the ETCC where it was especially successful. The 156 sports car program was run by Fiat Group's partner N.Technology S.p.A., originally founded as Nordauto Squadra Corse to compete in Italian Touring Car Championship. In 1994 name was changed to Nordauto Engineering and 2001 to N.Technology.[38] In 1998 Alfa Romeo also offered for sale the 156 Group N version for the track.[9] The 156 Group N had no carpets, seats or upholstery, but included additional track safety devices. The 156 has won the following titles:
