The Daewoo Lacetti is a compact car manufactured and marketed globally by GM Korea since 2002. The first-generation Lacetti was available as a four-door sedan and five-door station wagon, styled by Pininfarina—and five-door hatchback styled by Giorgetto Giugiaro. The sedan and wagon were marketed as the Suzuki Forenza in North America. The hatchback, was introduced in 2004 and marketed as Daewoo Lacetti5 in South Korea, Suzuki Reno in the United States, Daewoo Nubira in Europe, and elsewhere also as the Chevrolet Nubira and Lacetti.
In November 2008, the second-generation Lacetti was launched as the Daewoo Lacetti Premiere, a badge-engineered version of the Chevrolet Cruze, co-developed by GM Daewoo, Holden, and General Motors. It was marketed under the Daewoo marque until the beginning of 2011, when the brand was discontinued, and was thereafter marketed under the Chevrolet and Holden brands.
The name Lacetti derives from the Latin Lacertus, meaning youthful.
In Australia and New Zealand the Daewoo Lacetti was briefly sold between September 2003 and December 2004 as a four-door sedan. At this time, Daewoo withdrew from the Australian market. Fitted with the 1.8-liter engine rated at 90 kW (120 hp) and 165 Nm (122 lb⋅ft), the Lacetti offered standard five-speed manual or optional four-speed automatic transmission. The single trim level, called SX, included are dual front airbags, air conditioning, power steering, keyless entry, power windows, CD player, and an alarm. The special edition SX Limited from October 2003 added anti-lock brakes, side impact airbags, alloy wheels, climate control air conditioning, six-stacker CD player, tilt/telescopic steering wheel, lumbar support for the front passenger seat, and leather trim.
From 2005, the Lacetti (sedan and wagon) and Lacetti hatchback were sold together as the JF series Holden Viva. It was introduced at around the same time as the Daewoo Gentra-based Holden Barina. Unlike the Barina, however, the Viva was meant to be below the premium Holden Astra as a budget alternative.
Despite the Viva's lower price compared to the Astra , the Astra continued to outsell the Viva by a factor of about two-to-one.
With the release of the all new Holden Cruze in mid-2009 the Viva ceased to be sold in Australia. In New Zealand, where many cars are imported second-hand from Japan, several Japanese specification Chevrolet Optra sedans and wagons were also sold.
The Holden Viva was a small car produced by the Australian automaker Holden between 2005 and 2011. It was designed as a replacement for the Holden Astra, which was discontinued in 2004. The Viva was based on the Opel Astra, which is a popular car model in Europe, and was manufactured in South Korea by GM Daewoo.
The Viva was first introduced in 2005 and was available in both sedan and hatchback body styles. It featured a modern, sleek design and was equipped with a range of efficient four-cylinder engines. The base model was equipped with a 1.8-liter engine that produced 104 horsepower, while the top-of-the-line Viva SRi was powered by a 2.0-liter engine that produced 141 horsepower.
The Viva was well-received by consumers in Australia and was praised for its fuel efficiency, spacious interior, and comfortable ride. It also had a good reputation for reliability and durability. The Viva was marketed as a value-for-money option, and was positioned as a budget-friendly alternative to the more expensive European imports.
In 2008, Holden updated the Viva with a new front fascia and a revised interior, which included a new dash and steering wheel. The car's exterior was also updated to give it a more modern and sporty look. The Viva now featured a new grille, headlights, and front and rear bumpers. The interior was also improved with the addition of new upholstery and seat fabrics.
The Viva was offered in several trim levels, including the base model, the LS, and the SRi. The base model was equipped with features such as air conditioning, power windows and mirrors, and a six-speaker audio system. The LS and SRi models came with additional features such as alloy wheels, fog lights, and a sunroof.
The Viva was also equipped with a range of safety features such as front and side airbags, anti-lock brakes, and electronic stability control. These features helped the car achieve a five-star safety rating from the Australasian New Car Assessment Program (ANCAP).
In 2010, Holden announced that the Viva would be discontinued due to slow sales. The Viva was replaced by the Holden Cruze, which was a larger and more modern car that was also based on an Opel model. The Cruze was manufactured in Australia and was offered with a choice of four-cylinder engines and a turbocharged diesel engine.
The discontinuation of the Viva was met with disappointment from many Holden enthusiasts who had grown to appreciate the car's fuel efficiency, spacious interior, and comfortable ride. However, the Viva's replacement, the Cruze, was a worthy successor and was well-received by consumers. The Cruze was larger and more spacious than the Viva, and it was also more powerful and had a more modern design.
Overall, the Holden Viva was a well-designed and reliable car that was popular with consumers in Australia. It was a solid choice for a small car and was known for its fuel efficiency, spacious interior, and comfortable ride. Although it was not in production for very long, the Viva left a lasting impression on many Holden enthusiasts. The Viva was a budget-friendly and efficient car that provided a great value for money, and was well-liked by many who had the opportunity to own and drive one.
