The Opel GT is a two-seat sports car introduced in 1968 by Opel, a German possession of General Motors. It relied partly on components from the contemporary Opel Kadett B and had a body made by French contractor Brissonneau & Lotz.

Its styling has been likened to the 1968 Chevrolet Corvette which went on sale in September of 1968.^{[citation needed]}

Although the life of the GT was limited to six model years, after a 34-year hiatus it returned it as a 2007 model based on the Pontiac Solstice and Saturn Sky, and is built alongside them in Wilmington, Delaware, USA.

[edit] General information

The Opel GT was equipped with a base 1.1 L OHV straight-4 engine, which produced 67 hp (SAE) at 6000 rpm. However, most buyers chose an optional 1.9 L Cam-In-Head (CIH) engine, which produced 102 hp (SAE) at 5200 to 5400 rpm. Some of the early 1968 models also came with a slightly higher compression "H" code cylinder head. In 1971, due to emissions regulations, Opel reduced the compression ratio of the U.S.1.9 L engine and output fell to 83 hp (SAE). There was also a GT/J model, which was a less expensive version of the 1900GT sold only in Europe. Standard transmission was a manual 4-speed. A three-speed automatic was available with the 1.9 L engine. The model run of the Opel GT was from 1968 to 1973.

The Opel GT used a steel unibody and a conventional front-engined, rear-wheel drive layout. The Cam-In-Head (CIH) engine was mounted far back in the chassis to improve weight distribution. Front suspension consisted of double A-arms and a transverse leaf spring. A live axle and coil springs were used in the rear. The power-assisted braking system used discs in the front, drums in the rear. Steering was unassisted.

One unusual feature of the Opel GT was the operation of the pop-up headlights. They were manually operated, by way of a large lever along the center console next to the shifter. Unlike most pop-up headlights, they both rotated in the same direction (counterclockwise from inside the car) about a longitudinal axis. One standard joke about GT owners was that you can easily spot them due to the heavy muscles on their right arm built up by using the lever to pop up the headlights.

The Opel GT was a fastback, that had neither an externally accessible trunk nor a conventional hatchback. There was a parcel shelf behind the seats that could only be accessed through the main doors. Behind the parcel shelf was a fold-up panel that concealed a spare tire and jack.

The interior of the Opel GT was surprisingly large for a car its size, owing to its original design process (exterior metal was sculpted around an interior model). Headroom and legroom were sufficient for those over 6 feet (1.83 m) tall.

During 1968 to 1973, a total of 103,463 cars were sold. The most collectible GTs are probably the first few hundred cars hand-assembled in 1968 and the 1968–1969 models with the 1.1 L engine, which totaled out at 3,573 cars. Of the later cars 10,760 were the cheaper model (GT/J), which lacked nearly all chrome parts and less standard features. In some markets, items like a limited slip differential, front and rear anti-sway bars, heated rear window and engine bay light were standard, although most cars were shipped without them.

The Opel GT can be seen in reruns of some episodes of the last season of Get Smart. Agent Maxwell Smart drove a GT in several episodes, with the car featuring prominently in the opening credits.

[edit] Classic GTs today

The Opel GT shared many parts with other Opel models, mostly the Kadett B. Opel also used variants of the CIH engine from 1966 to 1995, so most parts are somewhat available. Also, in the USA and Europe, there are companies which specialize in Opel GT parts and services; including some new body parts. Some of the rarest and most costly parts are the ignition switches, rear trim strips, and 1968–1970 rear axle bearings.

One can fairly easily adapt larger engines, transmissions and brakes from newer Opels. For example, a fuel-injected 2.0 L engine (110 hp DIN) and a 5-speed Getrag manual transmission from an Rekord E or Manta B may be used to improve both fuel economy and performance.

There are GT owner clubs, some with very informative websites, such as the Opel Motorsport Club in USA (http://www.opelclub.com) and the very active Opel GT bulletin board website (http://www.opelgt.com). Numerous other Opel GT clubs are active in Europe, particularly in the Netherlands and in Germany.

Concept

On February 1, 2006, Opel issued a press release announcing the upcoming production of a new Opel GT, as a likely 2007 model. The car shares the GM Kappa platform with the Pontiac Solstice and the Saturn Sky. Unlike its platform mates, the 2.0 L, 194 kW (263.8 PS/260.2 hp) direct injection turbocharged Ecotec four-cylinder engine is being the only engine offered. It also features 18-inch alloy wheels, and a folding cloth top similar to those found on the Solstice and the Sky. Since GM's Saturn division already shares models with Opel, the GT is in fact Opel's version of the Saturn Sky. The car replaced the Opel Speedster in the European lineup; however, it is not sold in right-hand drive in the UK. The situation is similar to Holden in Australia, as the Saturn Sky and Pontiac Solstice are produced at a North American plant, which does not have the necessary tooling for producing right-hand drive vehicles.
