Holden Commodore VN

The Holden Commodore (VN) is a full-size car that was produced by Holden from 1988 to 1991. It was the first iteration of the second generation of this Australian made model, which was previously a mid-size car, as well as the first Commodore available as a coupé utility. The new range included the luxury variants, Holden Berlina (VN) and Holden Calais (VN) and, from 1990, introduced the commercial Holden Utility (VG).

Overview

The VN series was released on 17 August 1988 and it was a re-engineered hybrid of the European Opel Omega and Opel Senator. This donor body was paired to a Buick V6 engine or the Holden V8 engine. The project cost some .

As well as being highly based on the Opel Senator, the VN also was similarly based on the Opel Omega, but this time, the previous VL Commodore floor plan was widened and stretched. The Commodore could now match the rival Ford Falcon for size. The VN Commodore was available in Executive, S, SS, Berlina and Calais specification levels, although a more basic SL model (opt. code A9K) was supposedly offered to government and fleet buyers, as it was not officially listed as part of the Commodore range. The VN Commodore was also awarded ''Wheels Car of the Year'' for a second time in 1988. For the first time since 1984, Holden again offered a commercial coupe utility with the first-Commodore based VG Utility sold from August 1990. The Holden Statesman and Caprice (VQ) models, which were introduced in March 1990, were also VN Commodore based, but shared a longer wheelbase with the VN Commodore wagon and VG Utility.

Changes in the relative values of the Australian dollar, the Japanese yen, and the US dollar made it impractical to continue with the well-regarded Nissan engine of the VL. Instead, Holden adopted and domestically manufactured their own variant of the Buick LN3 V6 which was adopted from US market GM vehicles, although initially it was imported. Built with archaic rope seals for the rear main crankshaft seal and a floating seal carrier, these engines nearly all had problems with leaking rear main seals, with several TSBs issued to try and correct this poor design, to little effect. The 5.0-litre V8 remained optional and received a power boost to . Both these engines used multi point GM EFI and the V6 using 3 coil-packs for ignition. Although not known for its smoothness or quietness, the V6 was nevertheless praised for its performance at the time. A fuel-injected, 2.0-litre four-cylinder VN Commodore model was offered for some export markets including New Zealand and Singapore, which were sold as the Holden Berlina sharing an engine with the Opel Vectra A. Accompanying the changes to engines, the four-speed Jatco automatic transmission was replaced by the GM TH700 (also with four speeds) and the Borg-Warner T-5 five-speed manual gearbox.

A centre high-mount stoplight (CHMSL) was introduced prior to 1 July 1989 due to regulations in Australia requiring them to be fitted to all passenger cars manufactured from this date.

In September 1989 the Series II of the VN Commodore was released with the EV6 engine. Some of the changes included a new cast exhaust manifold, new camshaft sprocket profile and timing chain, improved air and fuel distribution to combustion chamber, recalibrated ignition and injector firing within the engine management computer, wider conrod bearings and revised throttle uptake. The automatic transmission was also recalibrated to match the new engines torque characteristics. These revisions helped reduce initial torque levels whilst also improving the noise and vibration levels of the V6 engine.

Under the Hawke government's Button car plan, which saw a reduction in the number of models manufactured locally, and the introduction of model sharing, the VN Commodore was rebadged as the Toyota Lexcen, launched in September 1989, named after the late America's Cup yacht designer, Ben Lexcen and replaced the previous similar-sized Toyota Crown S120 offered in Australia. Subsequently, the Toyota Corolla and Camry were, similarly, badged as the Holden Nova and Holden Apollo.

A total of 215,180 VN Commodores were manufactured during the model's 3-year lifespan, before production ended in September 1991.

A clone of the Commodore called the Beijing BJ6490 was produced in China under the brand Beijing Travel Vehicle Works for 1997 only. The car was powered by a 2.2 liter 4 cylinder engine and a hybrid version, the BJ6490D was shown at an Auto Show in 1998 and was priced at 140,000 yuan (20,180 USD).

;New Zealand

The VN series was assembled in New Zealand between 1988 and 1990. For the first few months of production it was actually assembled alongside its predecessor, the VL. This was due to the VL Commodore being slightly smaller, and offering a 2.0 L inline-six Nissan RB20E (for New Zealand only) or 3.0 L RB30E straight-six engine, also by Nissan.

A unique situation of the New Zealand VN Commodore was its trim levels. Where in Australia, Berlina was of higher spec than Executive; in New Zealand the roles were actually reversed. Commodore Executive was the Australian Berlina spec, while Berlina – had a similar spec to the Australian Executive models – and utilised a 2.0-litre '' Family II 20SE'' four-cylinder engine.

The Berlina four-cylinder model was a unique car for New Zealand (as well as a few other export markets) and was unavailable to Australia. The four-cylinder Berlina was developed in Australia primarily for the New Zealand market, it was equipped with an unemissionised fuel-injected 2.0 L motor (tuned to run on 96 octane fuel), essentially that of the Opel Vectra A mounted north-south, driving the rear wheels. The Berlina was available in both sedan and wagon body styles.

The Calais models were also offered to New Zealand, primarily in V6 form. In fact, due to a cancelled Singapore order, twenty fully equipped VN Calais models were sold in New Zealand – utilizing the Berlina's four-cylinder motor. Additionally, it is believed that there are a few VN Calais wagons in existence in New Zealand.

An indigenous sports model, the Commodore GTS, was also offered to the New Zealand market during 1990. Based on the New Zealand Executive models, the GTS featured a 3.8 L V6 engine, manual or automatic transmission, bodykit (similar to that of the VN Commodore SS), alloys and FE2 suspension. It was a limited build, available in either White or Dark Blue.

The VN was the last Commodore to be assembled in New Zealand, after General Motors New Zealand closed its plant in Trentham in late 1990. The last locally assembled model was a 3.8-litre Commodore V6, which came off the assembly lines on 21 November of that year. Thereafter, Holden cars sold in New Zealand came fully built up from Australia, from where they could be imported duty-free under the Closer Economic Relations agreement.

Commodore SS Group A SV

The SS Group A SV was a race homologation special based on the VN Commodore SS, which was built at Elizabeth, South Australia (Holden) but extensively modified at Clayton, Victoria (HSV). It was powered by a 4.9 L '' HEC 5000i'' V8 engine, which was mated to a six-speed ZF S6-40 manual.

The SS Group A SV existed primarily as a homologation special, created specifically so a racing optimised version of the Commodore could be utilised for Group A touring car motor racing. In fact, the regulations set down by the international governing body FISA at the time required a minimum of 500 road-going versions. HSV produced only 302 units in total. This shortened production run did not affect the SS Group A SV's homolgation thanks to the Confederation of Australian Motor Sport (CAMS) giving Holden special dispensation, in the hope of bolstering thinning grids in the 1991 Australian Touring Car Championship (ATCC).

Clubsport

The VN Series HSV Clubsport was released in June 1990 and was based on the VN Commodore. It was offered as a four-door sedan with a 5.0-litre Holden V8 engine.

Maloo

Special editions

In addition to the above mainstream models, HSV also built the following special editions and prototype, respectively:

;SV LE
Limited edition V8 model from August 1989. 110 sedans were built until September 1989, and 80 wagons until January 1990.

;Convertible prototype
Built in 1989 as a feasibility study—and bearing the eventual front styling of the VP series—this car never made it into production and is now displayed at the National Holden Motor Museum in Echuca, Victoria.

Motorsport

Group A

Group A regulations governed many touring car series between the 1980s and 1990s including in Australia, New Zealand, Great Britain, Japan, Italy, Germany and the European Touring Car Championship as well as the one-off 1987 World Touring Car Championship as well as significant races like the Bathurst 1000, Spa 24 Hours and the RAC Tourist Trophy.

The arrival of the Commodore SS Group A SV, coincided with the return of former Holden racing driver, Peter Brock, for the first time since their acrimonious split in 1987. Brock teamed with former three time Bathurst co-winner and HDT driver, Larry Perkins and his team for the first time since 1985 to run two cars under Brock's Mobil sponsorship. The team formed a two-pronged attack by Holden, which also comprised Holden Racing Team led by British driver Win Percy.

Engine outputs of this race car produced approximately , enabling it to reach with suitable gearing. It was also equipped with a specially homologated Holinger six-speed transmission, and their homologated racing weight was , down from the VL SV's .

The SS Group A SV — as was the rest of the field that included Ford Sierra RS500 and the BMW M3 Evolution teams — was outclassed in the 1991 ATCC by the Gibson Motor Sport built Nissan Skyline R32 GT-R' of reigning champion Jim Richards and his teammate, Mark Skaife. Major complaints by Holden drivers included that the VN SS Group A SV lacked downforce compared to the VL series SV. Reportedly, this was a consequence of Holden demanding that the car be more eye pleasing to its predecessor, which was given various nicknames including the " plastic pig". While the car had a better aerodynamic drag and was significantly faster in a straight line than the VL (at Bathurst that year, Brock recorded in the Tooheys Top 10 runoff, and aided by a tow from the Sierra of Dick Johnson was recorded at in the race compared to around for the VL the year before), it was slower through the corners due to the lack of downforce. This meant that while lap times at most of the shorter ATCC tracks stayed almost the same as with the VL, the VN's were actually slower at Bathurst by around two seconds, though in fairness the VL series had 3 years development compared to less than 1 year for the VN.

Brock gave the VN its only win in Group A racing when he won the opening heat of the first round of the 1992 Australian Touring Car Championship at Amaroo Park in Sydney, though both he and HRT were again uncompetitive during the season to the point that the leading Holden runner became Larry Perkins running a privately entered VL model. In September 1992 the VN was replaced as Holden's front line touring car for Sandown and Bathurst by its VP series successor. Brock's team was the only top team to run the VN Group A in the endurance races as the team's second car driven by Andrew Miedecke and Troy Dunston. The VN continued to be used by various privateers in 1993 and 1994 and last raced in the 1994 Australian Touring Car Championship by long time Holden running Sydney-based privateer, Terry Finnigan.

AUSCAR

The VN model was introduced to Bob Jane's AUSCAR category in the 1990/91 season. AUSCAR was based on America's NASCAR stock car racing, with the major differences being that the cars were based on the Holden Commodore and Ford Falcon road cars and were not pure space frame chassis like NASCAR. AUSCAR's also ran smaller V8 engines (5.0 L compared to 6.0 L) which developed less power, and as the cars are right hand drive, raced clockwise on the ovals tracks (the Jane owned Calder Park Thunderdome and the ½ mile Speedway Super Bowl at the Adelaide International Raceway) whereas the NASCAR's being left hand drive raced anticlockwise. The theory being that the driver was positioned on the side of the car that was furthest from the outside wall. Also unlike NASCAR, AUSCAR's used a control tyre with tread that was more like a road tyre than a pure racing slick.

The VN was instantly successful in AUSCAR racing and was soon a popular choice as a replacement for the older VK and VL models. Albury based touring car driver Brad Jones won three straight Australian championships driving his CooperTools Racing VN Commodore in 1990/91, 1991/92 and 1992/93.

NASCAR

A VN model Commodore was also developed for NASCAR racing in Australia. Bob Jane, wanting local involvement from Holden (Ford was already represented with the American Thunderbird model), pushed development of a left hand drive VN. Highly respected Roadways Racing chief mechanic Les Small developed the car which Allan Grice drove to a number of race wins in 1990 at both the Calder Thunderdome and Adelaide. The VN used a 358-cubic-inch (6.0 L) Chevrolet engine such as used in the Chevrolet Monte Carlo, Chevrolet Lumina and Pontiac Grand Prix NASCAR's.

Bob Jane had hoped to take the VN NASCAR for Grice to the United States to race in the NASCAR's Winston Cup series, but a fallout between himself as the sanctioning body in Australia, and NASCAR in the USA saw the VN remain in Australia. However, Bob Jane's dream of bringing a Commodore to race in NASCAR in the United States would come into fruition in 2013 with NASCAR's premiership, as General Motors made the decision to use a VF Commodore for the series in the United States, as the VF is sold in the United States as a niche market performance sedan known to Americans as the Chevrolet SS.
