The suspension and brakes got some serious attention too, and the Rally 1900 was quite the sensation in its brief heyday, and garnered a very positive review by Car and Driver. (see related story on C/D’s Opel Kadett assassination story). Until the Ascona/Opel 1900 (CC here) came along in about 1971, the Rally carried a bright flame for Opel. The Ascona had been planned as a replacement for the Kadett, but when Ford launched their very bare-bones Escort, Opel kept the Kadett on, although at least in the US, it reverted to a very basic trim level and only with the 1100 cc motor, and sales swooned, due to rising prices as a result of the falling dollar.
Styling wise, the Corsa OPC/VXR get more aggressive body kits with new bumpers, aluminium frames for the fog lights, a small scoop in the hood, a big roof spoiler and twin pipe Remus exhaust with a diffuser. Inside, the Recaro performance seats take centre stage, with other upgrades including the flat bottomed leather steering wheel, OPC gear knob and sports pedals along, as well as OPC design instruments.
The decklid badge says it's an automatic, but there's a four-speed manual inside. Was it a decklid or transmission swap? Either way, these cars were very, very cheap; the MSRP on a 1967 Kadett two-door sedan was $1,657 (about $12,500 in 2018 dollars), which compared favorably to the $1,639 Volkswagen Beetle that year. The Kadett had 54 hp to the Beetle's 53 (and weighed 93 fewer pounds than the Volks, to boot), so it was a bit quicker. On top of that, it had a heater that worked, plus a design dated a lot later than the late 1930s. Of course, most American car buyers looking for something economical preferred stripped-down versions of "traditional" American cars, e.g., the Chevy II ($2,090), the AMC Rambler American 220 ($2,073) the Ford Falcon ($2,118), or the Plymouth Valiant ($2,017). The Corvair two-door was $2,128 that year, too, and let's not forget the $1,790 Toyota Corona sedan.
The engine came with a choice from two power levels. For the standard 1.0 litre engine maximum output was listed as 40 PS (29 kW) at 5,000 rpm, and in October 1963 the high compression "1.0 S-Motor" was added, sharing the 993 cc capacity of the original power unit, but offering a maximum 48 PS (35 kW) of power at 5,400 rpm. The more powerful "S-Motor" engine featured modifications to the inlet manifold, cylinders and camshaft along with a carburetor employing larger (36 mm (1.4 in) diameter than the 30 mm (1.2 in) used on the standard engine. This came with an 8.8: 1 compression ratio whereas the 40 PS (29 kW; 39 hp) engine used a compression ratio of only 7.8 : 1. Higher compression ratios for performance versions of standard engines were a growing trend in West Germany in the 1960s, led by Opel and Ford, and made possible by the growing availability of higher octane "Super" grade fuel at filling stations.
A 1.6 L multi point fuel-injected engine with 101 PS (74 kW) at 5,600 rpm (98 PS or 72 kW in the catalysed version) and capable of 186 km/h (116 mph) was added to the Corsa/Nova at the 1987 Frankfurt Motor Show, giving decent performance and being badged as a GSi ("Nova GTE" in pre facelift models in the United Kingdom, later models were all called GSi).
The Kadett E (Vauxhall Astra Mark 2 in the UK) wis introduced in 1984, an wis votit 1985 European Caur o the Year, lairgely due tae its advanced aerodynamic body stylin. The 1984 model wis an aa developt intae a mair conventional three-box design wi a buit (trunk), badged as the Vauxhall Belmont in the UK an the Opel Monza in Sooth Africae, launcht in Januar 1986. This wis awardit 1985 Semperit Erse Caur o the Year in Ireland.
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
