Erich Bitter Automobil GmbH (Bitter) is a premium sports-luxury automobile marque originally produced in Germany and later Austria. Founder Erich Bitter, a former race car driver turned automobile tuner, importer and ultimately designer began crafting his own vehicles after business ventures with Italian manufacture Intermeccanica ended.
The Bitter automobile company initially produced vehicles between 1973 and 1989, selling them in Europe and the United States. Several prototypes were created by Bitter in later years with an eye on possible low-volume production, but none of those plans came to fruition until the Vero in 2007.
- Bitter CD - The Opel Diplomat-based CD, a three-door hatchback coupe featuring a Chevrolet 327 V-8 of 227 hp (169 kW), was built between 1973-1979. Inspired by the styling study OPEL CD (Coupé Diplomat) displayed in 1969 at the International motor show (IAA) in Frankfurt, it was the first car built by the newly formed Bitter GmbH.
- Bitter SC - The SC was based on Opel’s biggest contemporary model, now the Opel Senator, and was sold from 1979 until 1989 as a coupé, sedan and convertible. The SC was powered by a fuel-injected Opel 3.0 l-I6 (177 hp) or a stroked 3.9 l-I6 that developed 207 hp (154 kW). The bodywork design seems to have been heavily influenced by Ferrari`s 400i.
- Bitter Vero - After some lapse in production, Bitter’s next marketed model was the Vero. Sold between 2007 and 2012, the car is based upon GM’s Holden Caprice (WM) but with different front and rear treatments, 20 inch wheels, new suspension and a leather interior featuring DVD screens in the headrests. The V8 6.0 l 362 ch (266 kW) with six-speed automatic transmission of the Caprice is unchanged.
- Bitter Insignia - essentially a remodelling of the Opel Insignia, featuring the trademark Bitter grille and tail signatures, as well as a luxury bespoke leather interior.
- Bitter Adam (not pictured) - Bitter has applied its styling signatures to the Opel Adam, a car which also features a bespoke leather interior.
Clearly, with the passage of time, the Bitter brand has moved away from creating its own models on Opel floorplans. Now, the Bitter name is associated with luxurious upgrades of standard Opel models.
