The origin of the lightning in the 2012 Opel logo lies in the truck Opel Blitz (German Blitz = English "lightning"), which had been a commercial success, widely used also within the Wehrmacht, Nazi Germany's military. Originally, the logo for this truck consisted of two stripes arranged loosely like a lightning symbol with the words "Opel" and "Blitz" in them, in later, 1950s models simplified to the horizontal form of a lightning which appears in the current Opel logo. The jag in the lightning always follows the original from the "Opel Blitz" text stripes, in the form of a horizontally stretched letter "Z".
The Opel Eye front camera processes diverse data, thus forming the basis for the driver assistance systems such as Speed Sign Recognition and Lane Departure Warning. If the system registers that the lane is being left unintentionally it warns the driver by emitting audible and visible signals. Cruise control with speed limiter also makes driving more pleasant. Forward collision alert with pedestrian detection and Automatic Emergency Braking helps avoid accidents, and it is combined with a special Driver Drowsiness Alert.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).
