Chevrolet Astra

The Opel Astra (Lat: Stars) is a small family car (C-segment in Europe) engineered and manufactured by the German automaker Opel since 1991.

It is branded as Vauxhall Astra in the United Kingdom and the Buick Excelle XT in China. The Holden Astra was axed in Australia and New Zealand in 2009 owing to exchange rates making the car uncompetitive, and was replaced by the Holden Cruze. It briefly returned to the Australian market in 2012 as an Opel, but was discontinued after Opel withdrew from the country a year later.

The Astra is now built in Germany, the United Kingdom, Russia, Poland and China as well as being assembled from complete knock down (CKD) kits in other countries.

Naming convention
The Astra nameplate originates from Vauxhall who had manufactured and marketed earlier generations of the Opel Kadett (the Kadett D (1979–1984) and Kadett E (1984–1991)) as Vauxhall Astra. Subsequent GM Europe policy standardised model nomenclature in the early 1990s whereby model names were the same in all markets regardless of whether the vehicle was being sold as an Opel or a Vauxhall.

As of 2009, there have been four generations of the Astra. In a fashion typical for Opel they are designated with subsequent letters of the Latin alphabet. Opel's official convention is that the Astra is a logical continuation of the Kadett lineage, thus referring to the first generation of Opel Astra as the Astra F (the last Opel Kadett was the Kadett E). Another convention used by GM starts with Astra A, adopting the notion that the Astra is a separate model. Models sold as Vauxhall, Holden or Chevrolet have different generation designations reflecting the history of those nameplates in their home markets and their naming conventions.

Astra F (1991–1998)
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 an 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 three-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 three-door and station wagon models could be selected with the 151 hp (110 kW) C20XE engine. Some of Astra models had an 1.6 L engine with 83 hp.

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.

South Africa
The model was also launched in South Africa in 1991, where it was produced under licence by Delta. However, the "Kadett" name was retained for the hatchback Astras until 1999. The sedan and station wagon models were offered under the Astra name. Controversially, the Kadett and Astra in South Africa won the title of 'Car of the Year' in two consecutive years (1993 and 1994) even though they were versions of the same car. South African nomenclature was denoted in centilitres, so the Astra and Kadett ranges featured 140, 160i, 180i and 200i models. The South African Astra included a variant with a 2.0 L turbocharged engine called the Opel Astra 200t S. The 200t S was a specific name where Delta Motor Corporation wanted to show the specialty of the type, which could beat the BMW M3 in a quarter mile in that time. The 200t S stands for: 200 for the horsepower, t for the turbocharger and S for the six-speed transmission - which was unique in its class at the time. Both engine and chassis was produced in limited numbers (250 only) in both sedan and hatchback guise in Opel's Hungarian factory at Szentgotthárd. The engine (C20LET) in the Opel Astra 200t S was sourced from the Opel Calibra and Opel Vectra A 4x4 2.0 16V turbo, four-wheel drive found in European markets, but local engineers converted the six-speed, four-wheel-drive drivetrain (Getrag F28) to front-wheel drive only and as such it was unique to South Africa.

Other markets
The Opel Astra also became available in Australasia badged as a Holden, first in New Zealand in 1995, and then Australia in 1996. The first models were imported from the UK, but later models were imported from Belgium. The Holden Astra name had previously been used on rebadged Nissan Pulsar models from 1984 to 1989.

Opel Astra's first generation was imported to Brazil from December 1994 as the Chevrolet Astra, possible because of a lowering of import tariffs. Chevrolet of Brazil sent the 2.0-liter, 115 bhp engines to Belgium whence the completed cars took their way to Brazil. In February 1996 the Brazilian government again changed the import tariff, from 20 to 70% - making the car prohibitively expensive and leading to its cancellation after just over a year on the market. Instead, the locally built Kadett was updated. The second generation Astra was manufactured in Brazil.

Awards

 * 1992 – Semperit Irish Car of the Year
 * 1993 and 1994 – South African Car of the Year

Astra G (1998–2004)
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 Sedan 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 was built as Chevrolet Astra in Brazil. It was facelifted in 2003, and was sold in Brazil, Argentina, Mexico, and other Latin American markets until 2011. 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 four-door version of the Astra G as the Chevrolet Viva. It was sold through Chevrolet dealers in Russia, while Opel dealers were selling the newer Opel Astra H. 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.

V8 Coupe in DTM
The Astra G series Coupé look was used for the V8 powered dedicated race cars in the DTM series. These DTM cars are purpose built race cars with barely any parts taken from the road cars save for lights or door handles. The car's bodywork featured gull-wing doors that were each supported by two gas struts. The race cars were powered by 4.0L V8 engines with nearly 500 hp. Opel did poorly during several season of DTM as only Manuel Reuter placed significantly in the championship once, taking second in the inaugural season 2000. Opel won the 24h Nürburgring in 2003, though.

XTreme
The Astra XTreme, a concept presented at the 2001 Geneva motor show, was a single-production V8-powered Astra based on the G-series Astra DTM. Like the DTM race car, it featured a 4.0 L V8 engine, producing 444 hp, gull-wing doors supported by gas struts, carbon fiber panels, and race-specification interior with five-point seatbelts.

Stock Car Brazil
The season of 2005 also joined the history of Stock Car. In addition to the category have become multi - the first time the Mitsubishi Lancer ran alongside the Chevrolet Astra, on October 30 of 40 cars Stock Car V8 engine performed an unprecedented race outside of Brazil worth points for the championship. It was a round to the side of TC 2000, the main category of Argentina and in July had run in Curitiba (Autodromo Internacional de Curitiba). The Autódromo Juan y Oscar Gálvez received an audience of 70,000 people. Giuliano Losacco was the winner with Mateus Greipel second and Luciano Burti third. The engine was a V8 Chevrolet 350 imported from the United States by JL, similar to that used in Busch Series, the second category of NASCAR, equal and limited to 450 hp. Thus, the automaker GM is now sponsoring the category, providing the fairing of the Astra, making room for other manufacturers could enter the category with low investment.

Astra H (2004–2009)
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.

The aging Vectra B was replaced in Brazil with a sedan version of the Astra H, named Chevrolet Vectra, until it was replaced by the Chevrolet Cruze in 2011. 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, including Ireland in 2008. 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, which was replaced by the Chevrolet Cruze hatchback in 2011.

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 electronically controlled chasiss (IDS+) and AFL (Adaptive Forward Lighting).

OPC
During 2005, Opel introduced the OPC version of the Astra GTC (Sold as the Astra VXR in the UK) which is powered by an updated version of the 2.0 L turbo ecotec engine (Z20 LEH) producing 240 PS (177 kW, 237 bhp) and 320 Nm of torque. Standard features of the OPC version include sports bodykit and recaro interior, a six-speed manual gearbox, xenon headlamps and 18-inch alloy wheels amongst others.

This vehicle was sold until late 2009 in Australia and New Zealand by Holden Special Vehicles as the HSV VXR. HSV VXRs are sold as standard with full leather trim, climate control, 6 disc CD and 19-inch alloy wheels. HSV VXRs were badged as per the UK Vauxhall Spec models, but without the usual rear boot badge. Inside the Opel Blitz appears on the steering wheel with an OPC dashboard. The Astra OPC was also sold as the Chevrolet Astra OPC in Chile.

TwinTop
In 2006, the Astra TwinTop arrived. The "TwinTop" name also applies to the smaller Tigra refers to a folding hard-top coupé version of the car. In the case of the Astra, the TwinTop has a three-part folding metal roof which sits in the upper half of the boot space, leaving considerable luggage space below it. Still marketed as a four-seater, the rear seating space is smaller than a "normal" Astra. The TwinTop was available in three trim levels with a range of engines in each, including a 200 PS 2.0L turbo and the 1.9 CDTI diesel in 150 PS form.

Stock Car Brazil
In Brazil, Chevrolet Vectra (Astra H) substituted the Chevrolet Astra on Stock Car.The V8 is still the same, apart that now they use Ethanol instead of Petrol.

Saturn Astra
The Saturn Astra debuted during the 2007 Chicago Auto Show. Intended to replace the Ion as the brand's smallest model, the Saturn Astra was a captive import built in Antwerp, Belgium. It was offered in three and five-door hatchback body styles, with sales starting on January 2, 2008. Only one engine was available: a 1.8 L Z18XER inline-4-cylinder gasoline engine with variable-valve technology producing 138 hp and with an available five-speed manual transmission or a four-speed automatic transmission.

The Astra XE was available only on the five-door hatchback bodystyle version; this was the basic trim level for the Saturn Astra. The upmarket XR trim level was available in both the three and five-door hatchback. 17 in alloy wheels were standard with the XR, while the XE made do with steel wheels and plastic covers.

In Insurance Institute for Highway Safety (IIHS) crash tests the Astra earned a Good overall score in frontal impacts, while in side impacts it received a Marginal overall rating. Front and rear head curtain airbags and front seat-mounted torso airbags were standard.

General Motors predicted sales of between 30,000–40,000 vehicles a year in the United States. Sales were slow, due initially to a large glut of unsold Ions and later the uncertainty surrounding the Saturn brand's future. In 2008 only 11,968 were sold in the US and in 2009 this fell to 6,298.

At the end of 2012, Astravan was replaced by the new Opel Combo (whom the Astra H had already ended).

With a large number of unsold cars remaining on dealer lots, GM announced it would end importation of the Astra. In June 2009, GM announced its intention to sell the Saturn Corporation to Penske Automotive Group but this never was concluded and in 2010 General Motors discontinued the Saturn brand.

Engines

The Astra has been used in the shape of silhouette racing cars as well. It was featured in the Deutsche Tourenwagen Masters from 2000 to 2003 (Manuel Reuter was runner-up in 2000) and the Stock Car Brasil from 2004 to 2008 (Giuliano Losacco won the tournament in 2004 and 2005). In 2009, the Astra G body was replaced Stock Car Brasil by a Vectra, which is in fact the same as the Astra H.

The car has also been raced in the Russian Touring Car Championship.

A HSV VXR Turbo driven by Dutchman Ivo Breukers and Australians Morgan Haber and Damian Ward, won Class E (Production performance) at the 2013 Liqui Moly Bathurst 12 Hour in Australia on 10 February.
