There was also an Oldsmobile Omega, an unrelated vehicle that was produced during the 1970s and 1980s

The Opel Omega was an executive car produced by the German automaker Opel between 1986 and 2003. Replacing the Opel Rekord, it was voted European Car of the Year for 1987. Like the Rekord, the Omega was produced at Rüsselsheim in Germany. There were two generations of the model, the latter (Omega B) debuted in 1993. The Omega A was available in saloon and estate (Caravan) bodystyles as a competitor for the likes of the Ford Scorpio and Rover 800.

In the United Kingdom, the Benelux countries, Germany and Italy, the Omega was widely used as a police car and was once commonly used as a security vehicle to transport politicians etc. The car has also been converted into limousines and hearses.

Production of the Omega ceased in 2003. There was no direct replacement for it, as executive models from "non-prestige" manufacturers were proving less popular by the early 2000s; rival manufacturer Ford had pulled out of this sector in 1998 on the demise of its Scorpio. In 2009 Opel introduced Opel Insignia, (Vectra successor), which can be also considered as a Omega Successor (as it's the only comparable car since Omega production ending).

Development

The original Omega went into production in September 1986 as a replacement for the Opel Rekord, which had been in production since 1978. Sales began in November. The body was designed as an evolution of the previous Opel design theme engineered more towards aerodynamics in view of higher fuel prices and the general drive towards more fuel efficiency. The result was a remarkable drag coefficient of 0.28 (0.32 for the Caravan). The whole development program cost 2 Billion Deutschmark.

Compared to the Rekord, the Omega featured many modern technological advances, which were new to Opel in general, if not to the volume segment European automotive market. These included electronic engine management, ABS, on-board computer (which displayed parameters such as momentary fuel consumption or average speed), air-conditioned glove compartment and even the then-fashionable LCD instrument cluster (available in some version from 1987 but dropped in 1991). More importantly, the Omega came with a self-diagnose system (which is now a standard feature in present-day cars), whose output could be read by appropriately equipped authorized service stations.

Engines

All Omegas used a longitudinally-mounted engine with a rear-wheel drive setup, with a five-speed manual transmission or four-speed automatic transmission. The engine range consisted of 1.8 L, 2.0 L and 2.4 L four-cylinder units (2.0 L and 2.3 L Diesel, 2.3 L turbodiesel) to 2.6 L, 3.0 L, 3.0 L-24v six-cylinder units. In Brazil, the Chevrolet Omega/Suprema was powered to 2.0/2.2 four cylinders and 3.0 straight-6 Opel engine until 1994. Since the Omega A (and its 3.0 straight-six engine) was discontinued in Germany, the Brazilian GM factory needed a new engine for 1995. The cheapest (but not the best) solution was to fit the old 4100cc (250 cid), Chevrolet Straight-6 engine, a heavy and lazy engine compared to the original high-winding 3000 cc Opel unit.

Notable trim levels and special variants

The four basic trim levels were LS, GL, GLS and CD (from least to most expensive). The base LS was clearly intended for the fleet market, with the sedan not available to individual customers in some markets. The LS Caravan was also available as a panel van with rear side windows covered with body-colored foil rather than replaced by solid panels.

For the 1991 year, the Omega A was afforded a facelift, which encompassed slight alterations to front and rear fascias, as well as interior materials and additional sound dampening. The until-then base 1.8 L engine was dropped. The LS and GLS trim levels were also dropped, while the CD was joined by Club and CD Diamant.

Omega Diamant

This options package was introduced in 1988 and could be added onto the GLS, LS and CD trim version. It included alloy wheels, metallic paint, tinted windows, stereo with cassette player, various leather trim in the interior, as well as a painted grille and door mirrors. It sold well and the package was kept after the facelift and a similar system with the same name was used for the Omega B.[3]

Omega 3000 / Carlton GSi

The Omega 3000 was the sports version of the Omega. It featured a straight-6, 3.0 litre, 12-valve engine, which produced 177 bhp (132 kW; 179 PS) . Other modifications from the base model included a lowered suspension and limited slip differential, as well as different fascias and a rear spoiler. The car had a top speed of 222 km/h (138 mph), and accelerated from 0-100 km/h in 8.8 seconds.

In 1989, the Omega 3000 was upgraded. The engine now had 24 valves, two overhead camshafts, and a variable intake manifold (Opel Dual Ram system). It also used a more advanced engine control unit. Power increased to 204 bhp (152 kW; 207 PS) , which increased top speed to 240 km/h (149 mph), and 0-100 km/h time dropped to 7.6 seconds. In countries where the car was sold as a Vauxhall, the 3000 was called the Carlton GSi.

Omega Evolution 500

Opel Omega 500

This was limited series model produced together with Irmscher. It was built so Opel could compete in the DTM. The car had a 3 litre straight-6 producing 230 bhp (172 kW; 233 PS) . The car accelerated from 0-100 km/h in 7.5 seconds and had a top speed of 249 km/h (155 mph). The racing version used on the track had 380 bhp (283 kW; 385 PS), accelerated to 100 km/h (62 mph) in about 5 seconds, and could reach nearly 300 km/h (186 mph) . It did not achieve great success however.[3]

Lotus Omega/Carlton

Opel Omega with Lotus Engine

In 1989, a high performance version built in cooperation with Lotus was introduced. The car was named the Lotus Omega or Lotus Carlton, depending on whether the base car was sold as an Opel Omega or Vauxhall Carlton respectively. The car was built using a great variety of parts from other GM suppliers and car manufacturers. The engine was a 3,0 litre 24 valve item, and this was handed to Lotus for the tuneup. Lotus added a hardened and larger crankshaft, giving the engine its total size of 3,6 litres. Two Garrett T25 turbochargers were installed, along with a watercooled intercooler. The engine management was also changed and the ignition changed to an AC Delco type (same system as the Lotus Esprit uses). The result was a 377 bhp (281 kW; 382 PS) performance engine. The Omega also got a bigger differential from a Holden car with a 45% LSD, and the gearbox was changed to the 6-speed manual ZF gearbox from the Corvette ZR1. The tyres where custom made by Goodyear and can be recognized by the small Greek letter Ω (Omega) on the side. This was required as this car could reach 280 to 300 km/h (186 mph). This was a fact not popular at the time, as most of the other German car manufacturers that produced fast and powerful cars had already begun putting in speed limiters to limit their cars to 250 km/h (155 mph). The 1,663 kg (3,666 lb) car accelerated from 0 to 100 km/h (0 to 60 mph) in 5.3 seconds, 0 to 160 km/h (0 to 100 mph) in 11.5 seconds.[4][5]

[8]

Common Faults

The V6 engine is prone to cambelt failure, the initial 80,000-mile (130,000 km) service interval for toothed belt replacement was revised down to 40,000 miles (64,000 km) early in the model's life. Due to the fact that the engine is an interference design, failure of this component can result in serious engine damage. The service interval was revised to 100,000 miles for model year 2000 and later units when upgraded tensioner pulley were introduced.[citation needed]

  • hood (grill now integrated with hood)
  • tail lights
  • mirrors
  • new design of alloy wheels

Changes inside:

  • brand new central console with gps, air conditioning controls
  • ESP
  • brake assistance system

Engines

Late in 1999, the Omega received a facelift and a 2.2 L 16-valve engine was added to the range as an eventual replacement for the 2.0 L.

The following year, a 3.2 L V6 engine replaced the 3.0 L V6 unit, and a 2.6 L V6 engine replaced the 2.5 L V6 unit.

Opel was aiming to compete with BMW 5 and Mercedes E class, deciding of putting the V8 engine into at the time flagship model Opel Omega. There were prototypes of sedan and station wagon version (equipped with multimedia systems, and named V8.com).

Omega V8.com

The V8.com concept car project was meant to be a "mobile office" it was built on Omega station wagon which was elongated by 130mm, to provide more space for the passengers and additional equipment; containing separate 9.5 inch LCD screens for all passengers, internet access and integrated video conference mobile phone system with separate cameras and microphones providing passengers hands-free operation. Additionally the car was equipped with Xenon headlights, and Advanced Frontlighting System (AFS), automatically adjuststable to the road conditions.

Hence the name it was powered by a GM LS1 V8 engine.

The car debuted at Frankfurt Motor Show in 1999.[11]

Omega V8

Opel was planning to upgrade its flagship Omega model with powerful GM LS1 V8 engine used in Chevrolet Corvette.

Unlike V8.com which was the concept car, this model was intended to go into serial production.

Omega V8 was showed publicly for the first time at 70th Geneva Motor Show (March 2 - 12, 2000). A V8-engined version was to be put on sale autumn 2000.[12]

Cancelling

The reasons for cancelling production plans were concerns about whether the engine was vollgasfest (German, "Full throttle resistant") - the engine might overheat and be damaged if driven flat out on the Autobahn for long periods of time.[13]

Omega for different markets

Great Britain

Vauxhall Carlton

See main article: Vauxhall Carlton

In the United Kingdom, the Omega A was marketed as the second generation Vauxhall Carlton (the first generation Vauxhall Carlton having been a rebadged Opel Rekord) E2, and the Omega B generation as Vauxhall Omega. This generation introduced Vauxhall's corporate "V" chrome grille which would be seen in the forthcoming Vectra and facelifted Astra the following year. This grille design would remain a feature of all subsequent Vauxhall models until the 2009 Insignia.

America

Chevrolet Omega

See main article: Chevrolet Omega

The Omega was built and sold in Brazil badged as a Chevrolet Omega and Suprema (Caravan), but this name is now used for imported Holden Commodores.

Cadillac Catera

A badge engineered version of the Omega B MV6 was sold in North America under the name of Cadillac Catera.

Australia

Holden Commodore

See main article: Holden Commodore

The Omega B platform is the base, enlarged and modified, of the Holden VT Commodore and Holden VX Commodore, assembled in Australia and sold solely in the Australian and New Zealander markets.

End of the Omega

Opel Omega proved to be a successful car, being reliable and durable, after latest facelifting it was also very modern looking car, nevertheless, after 4 years since introduction of Omega B FL, Opel ended production of this model, not showing successor. On 25 June 2003 the factory left Omega B FL number 797,011. A silver 3.2-liter V6, was the last vehicle of this model built in Rüsselsheim.
