As the war progressed, military authorities placed greater stress on the development of air-cooled engines, which they felt had more immunity to damage from weather, shellfire, and misuse. To meet this demand, Opel engineers developed an unusual variation on normal cooling for the 3.6 L truck engine. It was called "air-oil cooling", and used engine oil to take heat away from the jackets around the cylinder barrels. The heads were directly cooled by air, there being three separate aluminium finned heads, each serving two cylinders. Of this interesting engine, which developed 72 hp (54 kW; 73 PS) at 3,000 rpm on 74-octane fuel, only three examples were built.
Joseph DeBattista and his son, Joey, acquired this Lapis Blue wonder after trading a Volkswagen. Owing to its rarity, they had to be creative with the restoration. While Joey was hunting for parts on eBay, his father bent metal to perfection, slowly completing a car that will always remain an underdog, a nice conversation starter, and a fail-proof daily driver. Just ask Richard Hammond, if you need more proof.

The Kadett C appeared in August 1973[12] and was Opel's version of the General Motors' "T-Car". It was the last small Opel to feature rear-wheel drive, and remained in production at Opel's Bochum plant until July 1979, by which time Opel had produced 1,701,076. Of these, 52% had been exported outside West Germany,[13] most of them to markets in other parts of western Europe.
In addition to its West German home market, the Kadett A sold strongly in what were becoming the manufacturer's traditional export strongholds (notably in Benelux, Scandinavia, Austria and Switzerland). Between February 1964 and the Autumn/Fall of 1965 the cars were also exported to the United States where they were sold through approximately 500 Buick dealers. The same 993 cc engine was fitted and it is not clear whether it was differently tuned for North America: horsepower ratings were differently computed in the USA, following locally devised "SAE" rules: for American market purposes the maximum outputs for the engines were quoted as 46 hp (34 kW; 47 PS) and 54 hp (40 kW; 55 PS).
The Corsa C arrived in the 2002 model year as a five door hatchback, and was imported from Europe; but for the model year of 2003, the Corsa sold in Mexico began coming from Brazil and a saloon version was added. In 2005, the saloon version introduced a semi-automatic transmission called easytronic because it was only offered in a five speed manual transmission, however, the easytronic transmission was rapidly discontinued after the model year of 2007, because of poor sales and technical flaws.[citation needed]

The manufacturer now offered two versions of the Kadett, designated the "Kadett KJ38 and the "Kadett K38" the latter also being sold as the "Kadett Spezial". Mechanically and in terms of published performance there was little to differentiate the two, but the "Spezial" had a chrome stripe below the window line, and extra external body trim in other areas such as on the front grill. The interior of the "Spezial" was also better equipped. To the extent that the 300 Mark saving for buyers of the car reflected reduced production costs, the major difference was that the more basic "KJ38" lost the synchromous springing with which the car had been launched, and which continued to be fitted on the "Spezial". The base car instead reverted to traditional rigid axle based suspension similar to that fitted on the old Opel P4.
1Opciono. Funkcioniše automatski iznad 5 km/h i ispod 85 km/h. Od 5 do 30 km/h, indikator usporenja da bi se umanjila brzina udara pri sudaru je 0.9 g. Od 30 do 85 km/h, sistem smanjuje brzinu za maksimalno 22 km/h. Nakon ove granice, vozač mora sam da koči kako bi dodatno smanjio brzinu. Raspon operativne brzine AEBPD-a zavisi od vrste otrkivene prepreke (pokretna meta: od 5 do 85 km/h; fiksna meta: od 5 do 80 km/h; pešak: od 5 do 60 km/h). Namena Opelovih sistema pomoći vozaču je podrška vozaču u okviru sistemskih ograničenja. Vozač ostaje odgovoran za zadatak vožnje.  Očekuje se da će biti dostupan od jeseni 2017.

Things are a little better up front, where we find driver and passenger seats approved by the Aktion Gesunder Rucken, or German Bad Back Association. They are truly, properly comfortable, and even long journeys fail to induce numb-bum, nor thigh-tremble. It does go a bit downhill from there though. The fascia and instrument panel are pulled, more or less directly, from the Corsa hatch, which means everything’s reasonably well made, but a bit dour and glum in appearance. That contrasts sharply to the quirkier, more welcoming interiors of the Crossland’s French cousins. There are good things – the seven-inch IntelliLink touchscreen is clear and good to use, albeit it has a slightly messy menu system, but the main dials look drab, and items such as the column stalks actually feel quite fragile and cheap.


Rüsselsheim/Geneva. Opel is paving the way to the future by providing even more information, services and safety in cars. The Rüsselsheim-based carmaker is presenting the personal mobility services offered by Opel OnStar – after already announcing the intention to bring Opel OnStar to Europe last year – at the International Motor Show in Geneva (Hall 2, Stand number 2231) ...
Instead, it had the same front fascia as the Latin American Chevrolet Corsa, possibly because GM South Africa wanted the same front fascia as the sedan and pickup, as swapping with the European front fascia would have been expensive sawing and welding due to the Latin American Corsa's sharper headlights. This car was 2001 Semperit Irish Car of the Year in Ireland.
This range of engines was also used for later models of the Corsa/Nova, and the mid-sized Cavalier/Ascona. From May 1981, the 1.3 was also available with a three-speed automatic. The automatic was made available to the diesel in September 1982. One interesting version which first appeared in mid-1982 was the Kadett Pirsch, (for deer stalking, a stealthy form of hunting). In non-German-speaking countries it was generally marketed as the Kadett Off Road. This was a station wagon with rustic trim, fitted with a differential brake, reinforced suspension and more suitable tires, increased ground clearance, a skid plate, and shortened front fenders.[17] In Sweden, a special postal Kadett ("Opel Kadett Post") was offered, fitted with a high roof (necessitating a unique and much taller windshield) and a sliding right-hand door, RHD, and the automatic transmission.[18] This version was converted by Karosseriefabrik Voll (in German) in Würzburg, Germany. Voll also made a postal version of the Kadett E.

In 1935 the time was ripe for the people’s car – from Opel, mind you. The P4 presented in November rolled of the assembly line soon thereafter. The four-seater with four-cylinder four-stroke engine – according to the P4 brochure “like the most expensive cars in the world” – cost only 1,450 Marks in the standard version. “How is this possible? To offer so much value, a real full-out automobile that even exceeds expectations for so little money?” The answer was clear: thanks to state-of-the-art mass production. This also came into play shortly thereafter with the Kadett 1, which also took over the design of the Opel Olympia. This made it one of the first German cars to feature a self-supporting all-steel body, which was more comfortable, safer and more durable than the conventional frame structures.
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.
On 29 February 2012, Opel announced the creation of a major alliance with PSA Peugeot Citroen resulting in GM taking a 7% share of PSA, becoming PSA's second-largest shareholder after the Peugeot family. The alliance was intended to enable $2 billion per year of cost savings through platform sharing, common purchasing, and other economies of scale.[25] In December 2013, GM sold its 7% interest in PSA for £250 million, after plans of cost savings were not as successful.[26] Opel was said to be among Europe's most aggressive discounters in mass-market.[27] GM reported a 2016 loss of US$257 million from its European operations.[26] It is reported that GM has lost about US$20 billion in Europe since 1999.[28]
The Kadett E (Vauxhall Astra Mark 2 in the United Kingdom) was introduced in August 1984, and was voted the 1985 European Car of the Year.[21][22] The 1984 model was also developed into a more conventional three-box design with a boot (trunk), badged as the Vauxhall Belmont in the United Kingdom, launched at Frankfurt 1985. This was awarded the 1985 Semperit Irish Car of the Year in Ireland. There was a station wagon called the "Caravan" available, with either three or five doors. In South Africa, the Kadett notchback was sold as the Opel Monza, along with a convertible.[23] This replaced the Opel Ascona.[24]
