The extra-light, all-aluminium engines, together with optimization of the front and rear axles, also contribute to the low total weight. The particularly compact three-cylinder petrol engines weigh around 15kg less than the previous generation of similarly powerful four-cylinder units. Highly unusual in the small-car-sector is the new Corsa’s aluminium engine bonnet, which although longer, saves 2.4kg in comparison to the previous model’s bonnet made of steel. The Insignia flagship was previously the only model in the Opel range with an aluminium bonnet. The seats also have been put on a diet. The new optimized seat structure saves a total of 10kg – 5.5kg at the front, 4.5kg at the rear. New lighter insulating material was used for fine tuning. Altogether the measures result in a weight reduction that, in combination with optimum aerodynamics and the efficient powertrains, will lead to a considerable reduction in fuel consumption and CO2 emissions.
The brakes were now controlled using a hydraulic mechanism. The suspension featured synchromous springing, a suspension configuration already seen on the manufacturer's larger models and based on the Dubonnet system for which General Motors in France had purchased the license. The General Motors version, which had been further developed by Opel’s North American parent, was intended to provide a soft ride, but there was some criticism that handling and road-holding were compromised, especially when the system was applied to small light-weight cars such as the Kadett.[3] By the end of 1937 33,402 of these first generation Kadetts had been produced.[4]
*Fuel economy values are determined through CO2 measurement in accordance with the latest ECE R101/SANS 20101 standards, as prescribed by South African government, conducted in a controlled environment and were correct at the time this disclaimer was published, which is subject to change. The specifications are for comparison purposes between the different vehicle models available in the S.A market which are all tested in the same manner, specific driving cycles and controlled environment.

For starters, the vehicle features numerous storage spaces for everyday items throughout the cabin. In addition, the rear seats are capable of sliding back and forth by up to 150 millimeters (6 inches), increasing the space in the second row, which is particularly useful for passengers with long legs, or increasing capacity of the luggage compartment.
The outdoor character created by the exterior design continues on the inside of the car with front door sill plates and the high gloss frame for the infotainment system The optional Radio R 4.0 IntelliLink system brings the world of smartphones to the KARL ROCKS via Apple CarPlay or Android Auto. As of this summer, buyers in search of an integrated navigation system can order the urban rocker with the Navi 4.0 IntelliLink system. The connectivity offering of the KARL ROCKS is rounded off by the availability of the Opel OnStar personal connectivity and service assistant including the new Personal Assistant service. It allows OnStar subscribers to book hotel rooms[1] and search for suitable parking spots[2] via an OnStar Advisor.
Both the Opel Karl and its Vauxhall Viva twin will be built alongside the new Spark in South Korea. Looking at the Opel’s measurements, we can see that the new 2016 Chevrolet Spark’s footprint will grow ever so slightly, with a 0.4-inch longer wheelbase and a 0.2-inch longer overall length. The new car’s roof is 3 inch lower overall, and the car could also weigh around 200 lb less than today’s model if the Karl’s 2070 lb curb weight is indicative of the U.S.-spec 2016 Spark’s specification.
Rüsselsheim.  In 2019 Opel celebrates 120 years of automobile production – and thereby 120 years full of innovations for everyone. The German brand has a tradition of pioneering high-tech advancements and quickly bringing them to series production. This makes mobility affordable for many and the cars safer, cleaner, more comfortable and more practical. The 120 years advertising campaign, “Opel. Born in Germany. Made for everyone.” is based on this philosophy. It was as true of the first Opel – the Patentmotorwagen “System Lutzmann” of 1899 – as of all the other models that followed, from the “Doktorwagen” to “Laubfrosch” (Tree Frog), P4 and Kadett. Today the philosophy matches the Opel Corsa more than any other model.
