The Holden Commodore (VT) is a full-size car that was produced by the Australian manufacturer Holden from 1997 to 2000. It was the first iteration of the third generation of this Australian made model and the last one to be powered by a locally made V8 engine (1999). Its range included the luxury variants, Holden Berlina (VT) and Holden Calais (VT) but not a new generation utility version.

Introduced in August 1997, the VT-series represented Holden's largest development yet. On debut, it won the 1997 Wheels Car of the Year, resulting in the fourth time that this award was won by the Commodore. It found ready acceptance in the market as many buyers steered away from the more radically designed Ford Falcon (AU), becoming the best selling Commodore and cementing its place as number one in Australian sales at its time.

A VT Series II (VT II) was released in 1999, before being replaced by the re-styled VX model in 2000. In 1998, the VT formed the basis of a prototype that became the catalyst for the re-introduction in 2001 of the Holden Monaro coupé—a nameplate on hiatus since 1977.

History of development

The station wagon variant of the third generation Commodore possessed a cargo volume of 2,683 litres (94.7 cu ft), compared to the sedan's 475 litres (16.8 cu ft). Model displayed is an Acclaim (VT II)

As with previous Commodore models, Holden looked to Opel in Germany for a donor car. The VT series was derived from the Omega B by broadening that vehicle’s width and adapting the mechanical setup for Australian conditions. The alternative would have been to adopt the Omega as is (which, notably, was also sold in North America as the Cadillac Catera between 1997 and 2001), save for the engines and transmissions or just reskinning the second generation (VN–VS) architecture.

The VT project ended up being a A$600 million development program that spanned more than half a decade. It sported many firsts for an Australian-built car (such as more advanced electronic systems), improved dynamics and increased crash safety also thanks to a body that was 30 percent stiffer than its predecessor, the VS series.

Its rounder exterior design, which made it more attractive to buyers than the more aerodynamic rival, Ford Falcon (AU), was considered only a styling exercise with low emphasis on aerodynamics given the sedan's ordinary drag coefficient of Cd=0.33. At the time of the VY series launch in 2002, Holden aerodynamic engineers conceded that the design was not ideal, primarily because of the rounded trailing edge of the sedan's boot lid, which did not promote a clean separation of the airflow off the back of the car as would have a sharper change of angle. As such, the VY series rectified this problem.

In 1999, the VT wagon platform served as the basis for the second generation Statesman and Caprice luxury cars. This third generation Commodore also formed the basis for the resurrection of the iconic Monaro coupé from the 1960s and 1970s. Presented as the "Holden Coupé" concept car at the 1998 Australian International Motor Show held in Sydney. Overwhelming public interest resulted in the coupé finally reaching production in 2001 as the Monaro albeit by then based on the VX series.

Input from the United States

Holden's parent company was interested in incorporating a left-hand drive Commodore into the Buick lineup in the United States and became involved in the VT development cycle early on. Holden was provided funds for the necessary engineering changes and a prototype was unveiled to the American public in 1995 as the Buick XP2000 concept car whose styling formed the basis for the VT series. The project, known internally as Project 127, was abandoned in early 1994, well before the VT's release but Holden made the most of the situation by exporting left-hand drive VTs to parts of Indochina and the Middle East badged as the Chevrolet Lumina, and to Brazil badged as the Chevrolet Omega.

Engineering

The VT heralded the fitment of semi-trailing arm independent rear suspension (IRS) as standard across the range. However, when originally carried over, the European design was simplified with the removal of the toe control link, standard equipment on the six-cylinder Omega since 1987. This design was prone to distorting the suspension camber angle and toe under heavy loads (e.g. when towing or travelling over undulated surfaces), leading to excessive rear tyre wear. Holden's performance arm HSV re-added the toe control link on the flagship GTS 300 model, based on the Series II update.

The base engine was the 3.8 L Ecotec V6 that Holden originally launched with the Commodore VS Series II. Apart from the Holden 5.0 litre V8 and HSV variants, the other engine offered was a supercharged version of the Ecotec, also previously launched with the VS II, which was uprated to 171 kilowatts (229 hp). and available as an option on the S, SS, and Calais models. The supercharged V6 availability was revised for the VT Series II. No longer available on the SS, it became optional on the Berlina and standard fitment of the Calais, although the naturally aspirated version could be specified as a "delete option". Safety wise, side airbags with torso and head protection became an option for the Acclaim and higher models in 1998 (a first for Holden and Australian manufactured vehicles) as were more advanced electronics from launch such as optional traction control and key-based memory settings for Calais.

Although considered to be part of the "VT Commodore" range, the Berlina and Calais luxury models were not badged or marketed as Commodore's and the Calais was only offered as a sedan. Apart from greater standard interior features as listed above plus such things as map lamps, footwell lamps, programmable interior dimming lights, auto-off lamp function, speed sensitive windscreen wipers (and, for Calais, including a woodgrain-look gear gate, chrome-look door handles, door lamps), the key differentiating exterior features of these luxury-oriented models relative to Executive and Acclaim included chrome-look grilles, side mouldings and bumper bars with chrome-look strips, chrome exhaust tips. In addition, the Calais featured lower skirt area of the Calais in contrasting paint (for a dual tone effect), chrome-look window mouldings, front fog lights, clear rear side indicators.

The range colours included: Heron (white and sole non-metallic), Rubens Mica, Capricorn Mica, Raven Mica, Orion Frost (silver), Valencia Mica, Tundra Mica, Botanica Mica, Granada Mica, Morocco Sand Frost, Bermuda Mica.

Special editions included the following:

• 1998 Commodore 50th Anniversary sedan and wagon (commemorating Holden's history)
• 1998 Calais 50th Anniversary (as above)
• 1999 Commodore Equipe (marketing package)
• 1999–2000 Commodore Olympic edition (commemorating the Sydney 2000 games)
• 2000 Calais International (marketing package).

Featuring special badging, with the exception of Calais, which featured unique limited edition parts, the rest of these special editions were base Commodores sold with extra equipment (e.g. full body-coloured bumper bars, standard alloy wheels—from Berlina for the 50th Anniversary—but without the luxury interior features such as climate control and full trip computer).

Series II

A limited edition Commodore Olympic (VT II), featuring the alloy wheels from a Berlina (VT), as standard

All facelifted Commodore (VT II) sedans featured clear side and rear indicator lenses originally exclusive to Calais (VT)

The Ecotec V6 remained the same, however, it received an updated tune that made the Series II of the V6 slightly faster than the original version. The VT had lost some of the performance of the VS due to the significant weight increase and thus could match neither its predecessor, nor, most importantly, its competitor, the AU Falcon.

The 1999 update replaced the venerable Holden 5.0 litre V8 with a new 5.7 litre Gen III V8 sourced from the United States. The VT II in Gen III V8 guise was claimed by Wheels magazine in 1999 to be the fastest Australian car ever. The V8 was detuned to 220 kilowatts (300 hp) from the original version, but would receive incremental power upgrades to 250 kilowatts (340 hp) throughout its time in the Commodore.

Cosmetically, all Series II VT models received slightly revised wheel covers and alloys, front grilles (silver accents on the base models and thicker horizontal chrome bars on Berlina and Calais) as well as clear side and rear indicator lenses (as fitted on the 1997–1999 VT Calais) instead of the previous amber. The updated Calais now also featured a chrome strip across the boot garnish above the number plate, to distinguish it from the lower model variants.

Holden Ute

Unlike in the case of its other new generation platforms, which saw Holden release a utility version concurrent to other mainstream body shapes, a VT Ute version was never developed. Instead, Holden continued to sell the VS Commodore utility version until December 2000, at which time the VU-series Holden Ute was released. This vehicle was based on the long wheelbase platform of the VX Commodore, itself launched in October 2000 as the first significant facelift of the VT series.

HSV range

See also: Holden Special Vehicles

The enhanced performance range of the original VT-based range sold by Holden Special Vehicles (HSV)comprised the following variants:

• Manta sedan with a 5.0-litre 195 kW V8 5-speed manual or optional 4-speed automatic
• Clubsport sedan with a 5.0-litre 195 kW V8 5-speed manual or optional 4-speed automatic
• GTS sedan with a 5.7-litre 220 kW V8 or optional 230 kW version 6-speed manual or optional 4-speed automatic
• Senator sedan with a 5.7-litre 220 kW V8 or optional 230 kW version 4-speed automatic with the 5- or 6-speed manual option
• Senator Signature sedan with a 5.7-litre 220 kW V8 or optional 230 kW version 4-speed automatic with the 5- or 6-speed manual option
• Senator Estate wagon with a 5.7-litre 220 kW V8 or optional 230 kW version 4-speed automatic only.

A limited-run XU8 model was also released powered by the last Australian-made 5.0-litre V8, due to be replaced by the imported 5.7-litre V8 standard on VT Series II cars. The launch of this series also introduced the short lived XU6 sedan, which was powered by the supercharged version of Commodore's 3.8-litre V6 engine.

Clubsport

HSV Clubsport (VT)

Launched in 1997, the HSV VT Clubsport was much larger and heavier than its predecessors. Critics noted that its engine, a 5.0 L V8 (producing 195 kW (265 PS; 261 hp)), was also available as an option on the Commodore SS, making the Clubsport less exclusive and desirable. The VT Clubsport did feature many luxury features, including a CD player, leather-wrap steering wheel, powered front seats and foglights.

The VT Series II was released in 1999 to replace the standard Clubsport. It featured a new 5.7 L V8 LS1 Gen III engine, sourced from GM Powertrain, producing 250 kW (340 PS; 335 hp). Production ceased in 2000.

GTS

• Series 1 VT GTS — 161 produced — 126 manual, remainder automatic
• Series 2 VT GTS — 100 produced

Senator Signature

HSV Senator (VT) sedan

Introduced in 1997 the VT gained the larger all-new bodyshell of the VT Commodore and also heralded the introduction of a Senator Signature wagon for the first time into the HSV range. An upgraded 195 kW (261 hp) 5.0 litre and 220 kW (295 hp) 5.7-litre V8 engines were offered. The VT Senator Signature came standard with speed-sensitive steering which would act in different ways depending on the road and surrounding conditions and luxury suspension tuned featuring Monroe Sensatrac shock absorbers. Appearance differed from other HSV models with the use of a chrome single-slat grille, side skirts, front fog lamps and 10-spoke 17 inch alloy wheels. The suspension was lowered, with leather seats and woodgrain standard throughout the Senator Signature.

The steering featured the Variatronic power assisted rack and pinion technology. The independent rear suspension and luxury front and rear Sensatrac variable rate dampers fitted made for smooth ride control and high speed stability. Additionally, HSV added complementary special features which were for the driver rather than the car, such as a Maglite torch, wheel nut cap remover and a multi-purpose pen knife. The VT Series II introduced a new 5.7 litre LS1 V8 which produced 250 kW (335 hp) and 473 N⋅m (349 lb⋅ft).

A choice of two transmissions were offered a 6-speed manual and 4-speed automatic. Front and side airbags, climate control air-conditioning and traction control are some of the features that come as standard. By activating a certain button in the cabin labeled "power" the automatic transmission holds the gears in longer, this gives the car more acceleration power. Storage wise the cabin offers, pockets behind the seats, door pockets, a large glove box and a console bin plus the larger boot.

The Senator Signature Estate Wagon had two versions available with this version the 195i and the 220i these was known by the badges found on the rear. The numbers that were chosen was to illustrate the power the cars had. Some of the optional features included an upgraded braking system, rain sensing wipers and luxury tuned suspension. Leather featured heavily throughout the vehicle and dual climate control was to enhance comfort for the passengers throughout the large wagon. A special entertainment audio system is only available as an extra option it includes a Premium audio pack with 350 watt power amp and 6 stack CD. There is an optional Coulson 'performance' front seating which is for extra comfort. The wheels are 10-spoke 17" x 8" alloy wheels. These days there are very few of these wagons left today.

Video games

HSV versions of the VT Commodore have featured in a number of video games. These include "HSV Adventure Racing", which was an adapted version of Beetle Adventure Racing exclusively for the Australian Nintendo 64 market, and, the "Need for Speed" collection.

Exports

Exports of the VT to the Middle East, rebadged as the Chevrolet Lumina, began in 1998.

In addition, General Motors do Brasil also imported the VT as the Chevrolet Omega from October 1998 to replace the same-named predecessor that was a rebadged Opel Omega A. The Brazilian model sold as a single-specification CD model, based on the Holden Calais automatic powered by the Ecotec 3.8-litre V6 engine. The VT II model came to Brazil in December 1999. VT Omega sales ended in 2001 when replaced by the VX-based model, as announced on 18 May 2001.

Production

Production of all VTs between August 1997 and August 2000 totalled 303,895 units. Of these, some 100,000 units were sold in the first 22 months leading up to the release of the VT Series II in June 1999, and 33,428 were exported.
