plans to import, modify and market the Opel Monza Coupé as the Holden Monza with the Holden 5 Litre V8 fitted, through his own HDT (Holden Dealer Team) business, but the plans eventually fell through. This was due to the expense of adapting the car to Australian Design Rules. One model was built with modifications, including a 5.0-litre Holden V8 engine. Other uses of the Monza name In South Africa, a saloon version of the smaller Opel Kadett E was also sold as the Opel Monza. In Brazil and Venezuela, a version of the Opel Ascona C was sold as the Chevrolet Monza, which featured a three-door fastback body unique to Latin America. There was also an unrelated Chevrolet Monza in the United States. Since 2019, Chinese buyers have been offered another Chevrolet Monza, this time a four-door sedan. 2013 Monza Concept The Opel Monza Concept is a three-door 2+2 fastback coupé plug-in hybrid concept car with 2 gullwing doors for easy access to the rear seats unveiled at the Frankfurt Motor Show in September 2013. The concept was also shown under the British Vauxhall marque. The concept shares the same basic plug-in hybrid setup as the Chevrolet Volt and Opel Ampera called "VOLTEC", but using a turbocharged 1-liter 3-cylinder natural gas-powered engine as its range extender instead of General Motors’ current 1.4-liter gasoline Voltec engine. The Monza Concept is the first car to feature cutting-edge LED projection infotainment. Dr. Karl-Thomas Neumann, the CEO of Opel has been quoted as saying "The Monza Concept is nothing less than our vision of the automotive future". According to Opel, this concept is the role-model for the next generation of Opel cars, and because of its modular chassis design, future cars based on it would be able to accommodate gasoline, diesel or electric power. Chief designer Ed Welburn of General Motors said "The gullwing doors will go into production and concept".
