Vectra C

Built over the Epsilon platform the Opel Vectra C of 2002 was initially available as a four-door sedan and a five-door hatchback, known as the GTS. A five-door station wagon was added in 2003, along with an "executive hatchback" sold under the Signum nameplate. The Signum, which is based partly on the Vectra C features a completely different layout in the rear.

The engine range was substantially modified to account for an increased curb weight. While a 90 kW (121 hp) 1.8 litre Family 1 Ecotec engine was reserved for the base model, a 2.0 litre turbocharged Family II engine with 129 kW (173 hp) was also offered, along with a new 3.2 litre V6, with 155 kW (208 hp). Diesel power, which by now was important for commercial success in Europe, is provided by an Isuzu-sourced 3.0 litre V6 outputting 132 kW (177 hp), but the four-cylinder diesel engine was replaced in 2004 by a Fiat-designed 1.9 litre Ecotec CDTI engine capable of outputting 110 kW (148 hp) in 16v form and 89 kW (119 hp) in 8v form. Handling is reported to be much better than the old car, but reviews still criticise the overlight feel of the steering, complicated indicator switches and the rather ungainly styling of the sedan version.

The Vectra received a facelift near the end of 2005, retaining a similar line of engines, however the 3.0 diesel received a power increase to 137 kW (184 hp) and the petrol V6 engine was replaced by an Australian-built turbocharged 2.8 litre High Feature V6 unit. This Saab co-developed motor could produce 170 kW (228 hp) for the facelifted Vectra. Opel installed the twin scroll turbo engine in its Signum productline with 185 kW (248 hp) output. The 185 kW (248 hp) version was available for Vectra later in 2006. Opel also introduced - for the first time - an OPC version of the Vectra, using the VXR name in the United Kingdom. These high-performance variants were available only in the hatchback and station wagon bodies. In the United Kingdom the power on the High Feature V6 engine was increased to 188 kW (252 hp), and maximum speed just falls short of 250 km/h (155 mph). In Australia and New Zealand, the Holden Vectra ZC series was dropped and replaced with the Holden Epica, a badge-engineered Daewoo Tosca in 2007. Due to stockpiling of 2005 model Vectras for the Australasian market, there was enough supply of the car for deliveries to last through to 2007, as a result facelifted Vectra Cs were not sold in those markets. In 2008, Vectra OPC was available with either 6 speed manual or 6 speed automatic transmission (Previous Vectra OPC had manual gearbox only). The 2.8L DOHC V6 turbo engine could generate 206 kW (276 hp).

Sales of the Vectra in the United Kingdom have not been as strong as its predecessors. For much of its production life, the original Vectra was the fourth best selling car in the country, yet the Vectra C has never come higher than tenth in the country's car sales charts, though it is still the second best selling car in its sector behind the Ford Mondeo. In 2007, it finally made the top 10 of Britain's car sales charts, being the nation's tenth most popular new car with over 50,000 sales, outselling the Ford Mondeo for the first time since 1999. Also in 2007, the station wagon variant garnered the Estate Car of the Year 2007 award by What Car? magazine.

While the Vectra C has been sold in Mexico and Chile as the Chevrolet Vectra, it is not marketed in Brazil, where Chevrolet opted to sell the Astra C under the Vectra brand since October 2005, keeping the Astra B as the cheaper option. Both local-spec cars are powered by the FlexPower SOHC engine originally introduced in 1982 in the Chevrolet Monza.

Vectra B

The second model, the Vectra B, was introduced in 1995, and the model range included an estate version for the first time. This model replaced the Vauxhall Cavalier in the UK. The Vauxhall badged Vectra B was the last Vauxhall to be produced at the company's Luton plant, where the end of automobile production was announced at Christmas 2000, taking effect just over a year later.

The model was badged as the Holden Vectra in Australia and New Zealand. In 1998, Holden began assembly of the Vectra for export to other right-hand drive markets in the region, although this was adversely affected by the Asian economic crisis, and ended in 2001.

Engines started from the 71 PS (52 kW) 1.6 L, Family 1 but eventually the 8-valve engines were all replaced by 16-valve powerplants. The 2.0 L Family II engine, with 136 PS (100 kW) was developed as a basis for touring car racing (later in Australia, 2.2 L 108 kW), but the top of the line was a 2.5 L V6 with 170 PS (125 kW). Diesel power came once again from Isuzu, with 1.7 L 82 PS , also 2.0 L Ecotec with 82 PS or 101 PS and 2.2 L Ecotec with 125 PS.

In 1999 the Vectra was updated, receiving a mildly modified body (that can be identified by the single piece headlight units and body-coloured bumpers) together with somewhat improved handling characteristics and better equipment.

Sporting limited edition models included the touring car championship inspired i500, Super Touring and GSi. The first model was developed in Germany by Opel Motorsport, with the V6 engine's power increased to 195 PS (143 kW), and the other two were created in Milton Keynes by Motor Sport Developments, the team that run the Vectras in the British Touring Car Championship (BTCC). Only 3900 2.5 GSi models were ever produced, mostly in saloon and hatchback guise. With only 317 estate versions produced during this time, they became one of the rarest production Vauxhalls ever.

On model years 2001 and 2002 a last of the line 2.6 GSi was made also but these were limited to 500 cars. These were again mostly saloons and hatchbacks however 37 estates were made. These models received a host of extra upgrades including but not limited to Xenon headlights and larger front brakes.

In Egypt, the production of the Opel Vectra B continued in mid-1996 with two models, initially a 1.6l 8v GLS trim with manual transmission and a 2.0l 8v CD trim with automatic transmission. Later in 2000 the revised model was produced with three models 1.6 8v GLS trim with manual transmission (later replaced by the 1.6 16v GLS trim with automatic transmission), 2.0 16v CD trim with automatic transmission, and a 2.0 CDX trim automatic transmission and all with saloon body style. In 2002 local production of the Opel Vectra ceased in favour of the Opel Corsa Sedan and Opel Astra Sedan.

A related model sold in North America was the Saturn L-Series, introduced in 2000 but dropped from the lineup in 2005. It was replaced by the 2007 Saturn Aura, which was built around GM's Epsilon architecture, as the Vectra C is.

Vectra A

The first Vectra, known as the Vectra A, was introduced in 1988 as a saloon and hatchback, replacing the Opel Ascona C. A coupé based on the Vectra, called the Calibra, was also sold. Both cars were designed by the Opel design chief at the time, Wayne Cherry. Vauxhall Motors, the British GM subsidiary that shared most of its models with Opel, did not use the "Vectra" model name. It marketed the car as its next generation Cavalier.

Engines ranged initially from a 75 PS (55 kW) 1.4 L to a 130 PS (96 kW) 2.0 L Family II. With the introduction of Euro I emissions regulations, the base model was replaced by a 1.6 L with the same output, while the top of the line was given to a 16-valve version of the 2.0 L engine, which powered the GT (GSI) version, and had 150 PS (110 kW). Four-wheel drive versions were added to the lineup in 1990, and in 1993, the car received a limited edition turbocharged version, with 204 PS (150 kW). The 1.4-litre engine was not available in all markets, and even then, it was only available in basic trims (Base/L in United Kingdom, LS/GL in Europe). A 2.5 L V6 engine appeared towards the later stages of the Vectra's life, developing 170 PS (125 kW), turning the car into a relaxed motorway cruiser rather than give it sporty pretensions.

There were a choice of two diesel engines; one was an Isuzu 1.7 L Circle-L I4 unit, in both naturally aspirated and turbocharged form (1686 cc), this one capable of achieving 82 PS (60 kW), and a Opel designed 1.7 "low blow" turbodiesel (1699 cc), and naturally aspirated diesel unit, delivering up to 68 PS (50 kW; 67 hp). Both units have a reputation for longevity, especially Isuzu developed units, which were also regarded as some of the most refined diesels available at the time.

The front suspension was fully independent, with MacPherson struts, pressed steel lower control arms, and an anti-roll bar. The front suspension, together with the major mechanicals (engine and transmission) is remotely mounted on a front subframe. On front wheel drive models, the rear suspension is semi-independent, consisting of a torsion beam axle linked to trailing arms, with double conical coil springs and direct acting telescopic hydraulic shock absorbers, with certain models also having an anti-roll bar. On the four wheel drive GSi, the rear suspension is a subframe-mounted fully independent design, with semi-trailing arms, double conical coil springs, direct acting gas-assisted telescopic shock absorbers, and an anti-roll bar. Steering gear is a rack and pinion type (manual or power assisted, depending on model), mounted on the bulkhead (firewall), with a telescopically deformable steering column.

The Vectra also received a refresh in 1992. The range received new front grilles and a black plastic strip above the rear tail lights, along with an upgrade to the structure for improved crashworthiness. Airbags became available from 1993 onward.

The Vectra gave birth to a coupé version, the Opel Calibra, which shared the Vectra's underpinnings, including the most powerful engines (115 PS and up) and transmissions.

In New Zealand, the Vectra A was offered initially as an Opel, but it wore Holden badges from 1994. It was not sold in Australia, where Holden instead offered a rebadged Toyota Camry called Apollo until 1997.

In Brazil, the Chevrolet-badged Vectra A was not introduced until 1993, when it replaced the Chevrolet Monza, a restyled version of the Ascona C.

In Egypt, the Opel Vectra A was not introduced until 1994 through GM Egypt Dealerships, and started production in late 1994 by GM Egypt through early 1996 with a range of 1.6 GL, 2.0 GL trim and 2.0 GLS trim and only Saloon body style boosting strong sales during this short run.

Astra H

The Astra H was launched in March 2004 as a five-door hatchback, whilst a five-door estate launched late 2004 and a sporty three-door hatchback, designated the GTC (Gran Tourismo Compact) for European markets, Sport Hatch in the UK and the Coupé in Australia, launched in 2005. The GTC has the option of a windscreen called "panoramic windscreen" (unique for a production car at the time of its launch) which extends into the roof area.

Based on the then-new Delta platform, its size was increased compared to the previous version.

In the 2005 European Car of the Year contest, the Astra H was just edeged out by the top three, Toyota Prius, Citroën C4 and the Ford Focus.

In 2005, a Diesel-Electric Hybrid prototype was presented but not put into production, whilst the aging Vectra B was replaced in Brazil with a sedan version of the Astra H, named Chevrolet Vectra. The model was matched with the others models offered in Brazil. This version was offered as an Opel in some Eurasian markets in 2006, following a debut at the international auto show in Istanbul, Turkey. This was manufactured in Gliwice, Poland. Also in 2006, the Astravan, a 3-door van variant of the estate, was launched.

In September 2007, a version of the 5-door Astra was launched in Brazil, marketed as Chevrolet Vectra GT to differentiate from the already existing Astra G, which remains in production with a lower price.

In 2008, the Astra sedan was launched in Ireland as the Opel Astra Saloon, one of the countries in Western Europe where it was sold. In Spain it is sold as Astra "Sedán".

GM Russia launched SKD assembly of Astra on a temporary production site near Saint Petersburg in February 2008, with a potential capacity of 25,000 vehicles annually.

The Chevrolet Astra was withdrawn from Mexico in 2008 as a result of withdrawal of Opel products from the brand, replaced by the Chevrolet Cruze sedan for the 2010 model year.

A first for any major European car is the availability of digital radio on some versions of the new Astra, while for the Astra product class first are electronic Continuous Damping Control (CDC) and AFL (Adaptive Forward Lighting).

Astra G

The Astra G was launched in Europe in 1998. It was available as a 3 and 5-door liftback, 4-door saloon, 5-door station wagon and two special versions from 2000: the Astra Coupé and the Astra Cabrio, both of them designed and built by Bertone. The Astra G saw the introduction of a natural gas-powered engine. Its chassis was tuned by Lotus and formed the base of a seven-seater compact MPV, the Opel Zafira. Approximately 90,000 coupes were produced, of which 7000 were cabriolets.

The manufacturing of Astra G continued at Opel's Gliwice plant in Poland after the debut of the next-generation Astra H, with the older model being branded as Astra Classic in a similar fashion to its predecessor, catering to the lower end of the market. This car was offered in Central and Eastern Europe, as well as Turkey with the name Astra Classic II from 2004 to the end 2009. Apart from European markets, these models were sold in Australia and New Zealand as Holden Astra Classic, until they were replaced by the Holden Viva in 2006.

The Astra G continues as the locally built Chevrolet Astra in Brazil. It was facelifted in 2003, and is sold in Brazil, Argentina, Mexico, and other Latin American markets. In Brazil, the Astra G/B remains as the leader of its segment in sales since 1999. The GM Brazilian 2.0 8V I4 engine which equips the Astra has the "flexpower" technology, that allows the car to run on both petrol/alcohol fuels, providing 128/140 hp (G/A) at 5200 rpm.

A taxi version of the Brazilian sourced model, powered with gasoline 2.0 engine was sold in Chile as the Chevy Urban.

In 2004, GM's Russian joint venture, GM-AvtoVAZ, launched the GM-AvtoVAZ Chevrolet Viva, a four-door version of the Astra G/B. It was sold through Chevrolet dealers in Russia, while Opel dealers were (and are, as of July 2008) selling the newer Opel Astra H/C. Sales were poor from the start due to high pricing: the only version launched was equipped with a 1.8L engine with an above-average trim level, placing the Viva's price above the Toyota Corolla. A project costing $340 million was selling less than a thousand cars annually (801 cars in 2007); rumours of shutting down Chevy Viva production circulated as early as summer of 2005. GM-AvtoVAZ shut down small-scale production of the Viva in March 2008.

Astra F

The Opel Astra F debuted in October 1991. With the Kadett E's successor, Opel adopted the Astra nameplate, which was already used by Vauxhall for the Kadett D and E (see Vauxhall Astra). It was offered as a three or five-door hatchback, a saloon (sedan), and a estate (wagon) known as the Caravan and available with five doors only, bringing Opel's run of three-door wagons to an end at long last. A cabriolet was also offered, designed and built by Bertone in Italy. While the Astra F finished production in Germany in 1998, Polish-built Astras remained on offer in Central and Eastern Europe, as well as Turkey, with the name Astra Classic from 1998 to 2002.

The Opel Astra F consisted of two main revisions and was revised in 1995, with the launch of Opel's new Ecotec engine. For a short period, a submodel which consisted of parts from both revisions was produced. The submodel used all the new Ecotec running gear, but many parts from the previous revision were used in order to use up leftover parts. Other main changes included mildly altered exterior styling, and availability of new specification models.

Aside from the South Africa-only Opel Astra 200t S, the lead model was the GSi — a 2.0 L I4 16V petrol injected model with 151 hp (110 kW), available as a 3-door only. It also featured sports bodykit and widened front seats in the interior. However, this was substituted in 1995 and was renamed as SPORT, although only a limited number were produced and the bodykit was removed also and it could be selected with the lower-powered, but more modern 'Ecotec' version, the X20XEV (136 hp, 100 kW) parallel with the C20XE. In Europe from 1994 all Astra models were offered with the 2.0 L 16V ECOTEC X20XEV parallel with the 2.0 L 8V (C20NE) engine, but the 3-door and station wagon models could be selected with the 151 hp (110 kW) C20XE engine.

After the Astra F was replaced by the new generation Astra G in 1998, the so called "REDTOP" C20XE engine was also taken out of production.

Zafira Tourer C

     The third generation Zafira Tourer was previewed in concept form at the 2011 Geneva Motor Show, as the 'Zafira Tourer Concept'. It has been revealed that, when the Zafira Tourer C goes on sale, the Zafira B will remain on sale, albeit in facelifted form, to act as a smaller and cheaper version, as the Zafira Tourer C is to increase in size to act as a proper rival to the Ford S-Max. A hybrid and/or electric version is expected to follow during 2012.

The production version debuted at the 2011 Frankfurt Motor Show in September, and went on sale late 2011.
A natural gas version of the Zafira Tourer was announced in December, 2011. A dual-fuel vehicle, its CNG tank will drive the car 530 kilometers, and a 14 liter gasoline tank provides additional range or operation when a CNG filling stations isn't unavailable.
