The Kadett featured a more modern design than the Volkswagen Beetle that then dominated the market for small family cars in West Germany and various surrounding countries. The Kadett offered more passenger space, more luggage capacity, and better visibility for the driver. Its water-cooled engine provided effective heating for the passenger compartment. However, by the mid-1970s the Kadett's weakness was already apparent as the car's bodywork was not well protected from corrosion.
For 1937 the Kadett was offered as a small and unpretentious two door "Limousine" (sedan/saloon) or, at the same list price of 2,100 Marks, as a soft top "Cabrio-Limousine". The body resembled that of the existing larger Opel Olympia and its silhouette reflected the "streamlining" tendencies of the time. The 1,074cc side-valve engine came from the 1935 Opel P4 and came with the same listed maximum power output of 23 PS (17 kW; 23 hp) at 3,400 rpm.
The Corsa C was introduced with a 1.7 L DTI Ecotec turbodiesel engine supplied by Isuzu (Circle L) with 75 hp (55 kW). This was later joined by the 1.7 L DI Ecotec turbodiesel engine also supplied by Isuzu. The 1.7 L DI Ecotec did not include an intercooler and this reduced power to 65 PS (48 kW). From 2003, a new 1.3 L CDTI Ecotec turbodiesel engine was supplied by Fiat (MultiJet) which produced 70 PS (51 kW) and a 1.7 L CDTI Ecotec turbodiesel was supplied by Isuzu which produced 100 PS (74 kW). This new 1.7 L CDTI Ecotec featured a variable geometry turbocharger.
After the closure of Opel Australia, Holden imports newer Opel models such as the Astra GTC (ceased 1 May 2017), Astra VXR (Astra OPC), Cascada (ceased 1 May 2017), and Insignia VXR (Insignia OPC, ceased 1 May 2017), under the Holden badge. The 2018 5th-gen Holden Commodore ZB is a badge-engineered Opel Insignia, replacing the Australian-made, rear-wheel drive Commodore with the German-made front-wheel/all-wheel drive Insignia platform.
The Opel Performance Center in 2011 launched a hardcore version of the Corsa OPC – Corsa OPC Nürburgring Edition. The engine is the same, 1.6 litre turbo, but it has been tuned to punch out 210 PS (154 kW; 207 hp) and 250 Nm (280 Nm with overboost function) of torque at 2,250 to 5,850 rpm. 0–100 km/h time is 6.8 seconds and top speed is 230 km/h (143 mph).
While at the AVUS-ring, John Winter suffered a horrendous accident after being nudged by one of the Mercedes on the opening lap. He was pitched into a high-speed half-spin to the right, and hit the barriers with enough force to rupture the fuel tank. A gigantic fireball erupted from the destroyed car, but Winter was able to crawl out relatively unscathed. With only minor burns to his face, he was lucky to be alive.
The Opel Kadett D was also built in South Africa by General Motors South African (Pty) Ltd. The South African range was made up of four-door fastback sedans, five-door hatchbacks, and a five-door estate model called the Voyage. The engines used are Opel's 1.2 litre overhead valve inline-four (L models only), or the OHC 1.3 liter (GL, GLS, and Voyage). Power is 60 PS (44 kW) and 75 PS (55 kW) respectively. Later a 1.6 liter was added and also a 1.8 in the GTE performance model.
The handling and ride are basically fine, but are all but invisible from the point of view of a keen driver. The Crossland is tidy through corners, with reasonable steering weight but no actual feedback, and the body tilts over only to a reasonable angle. The ride is a touch stiff in its damping, especially around town (which is disappointing, given that any Crossland will probably spend most of its life in town) but it does improve on the open road. Refinement is only average though with quite a bit of wind and road noise. There’s little point in having Opel’s phone-based OnStar concierge service fitted if you can’t hear what the operator is saying . . .

In March 2017, Groupe PSA agreed to buy Opel, its British sister brand Vauxhall and their European auto lending business from General Motors for US$2.2 billion. In return, General Motors will pay PSA US$3.2 billion for future European pension obligations and keep managing US$9.8 billion worth of plans for existing retirees. Furthermore, GM is responsible for paying about US$400 million annually for 15 years to fund the existing Great Britain and Germany pension plans.
