The Kadett D was introduced in the middle of August 1979, with deliveries on the home market beginning early in September 1979. In November 1979, the car went on sale in the United Kingdom, some five months before the Vauxhall Astra Mark 1, the British version, was launched in April 1980. The cars were designed as three- or five-door hatchbacks and estates or station wagons. There were also two- and four-door sedans featuring separate boots/trunks, which shared the silhouettes of the hatchbacks: in the United Kingdom, the sedan versions were soon withdrawn, until the 1986 launch of the MKII-based Belmont. For the first time since 1965 there was no coupé-bodied Kadett in the range: the previous Kadett C coupé was indirectly replaced by the three-door 1.3 SR sports model.
My dad bought a Kadett when we became a two-car family in the 60’s (Mom got the Rambler Rebel, and then a 72 Impala). It lasted until ’77, when we used the Impala to help push it down the highway and into the Olds dealership where they were having a “We’ll give you $1000 for whatever you can drive onto the lot” trade in sale. (Sadly, we got an awful 77 Cutlas Supreme). I got some of my early driving lessons (in the neighborhood) in that Opel – shifting gears from the passenger seat, or sometimes riding on my Dads lap and steering.
You may remember the beloved Opel Kadett A named “Oliver” that Richard Hammond of Top Gear fame slogged through the Makgadikgadi Salt Pan of Botswana. He became so attached to the little car that he had it restored and owns it to this day. Hammond’s love of this classic comes with good cause as it was a secret weapon of Opel developed specifically to invade the dominance of Volkswagen during the 1960s. Even though it delivered similar levels of horsepower (around 40 hp) it did offer better heating as well as more interior and luggage space. The Kadett’s popularity and engine reliability provided a resurgence for Opel and the car was exported to many countries including the United States. Whether you punish yours in the muck and mud or reserve your driving strictly to the road is entirely up to you.
But how was Opel/PSA able to shave off so much fat from the hatchback? For starters, all engines will be made from aluminum (-15 kg / 33 lbs), much like the hood (-2.4 kg / 5.3 lbs). The optimized seats (-5.5 kg / 12.1 lbs front and -4.5 kg / 10 lbs rear) contribute to this significant weight loss, while the insulating material used throughout the cabin is also a new weight-saving development. The most important diet is found in the body-in-white, which is a term referring to the body panels being joined together before adding the engine, sub-assemblies, and trim. The new BIW is an impressive 40 kg (88 lbs) lighter than the old one.
the Chevy Chevette, while a MUCH better car than the Vega was at the time, and even now, that’s not saying a whole lot, other than it WAS infinitely more durable and longer lasting and reliable than the Vega, though by ’76, the Vega was decent enough, but the damage was done. I know as my Mom drove a ’76 Vega from roughly 78-83 with the only major thing being the carb being rebuilt around 1980. The Chevette was basically a redesigned Kadett/Vauxhaul Chevette.
