The Opel Monza Concept is a 3-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".
