General Motors' Opel subsidiary in Europe designed a compact V6 engine with an unusual 54° vee angle. It was an iron block/aluminum head DOHC design with 4 valves per cylinder. All 54° engines were assembled at Ellesmere Port in England.
In the early 1990s, Opel identified the need for a modern, lightweight and compact power plant to replace its ageing straight-6 engine range. These engines have a cast iron engine block with cast aluminium alloy cylinder heads. The cylinder heads contain 4 valves per cylinder actuated by dual overhead camshafts which are driven by a timing belt. These engines however, differed from many modern V6 engines in that it has a 54 degree cylinder bank angle; as opposed to the more conventional 60 degree setup. This added to the engines' compactness which was needed to allow its use in front-wheel drive applications, as well as rear-wheel drive cars. Other features of these engines include: an oil to water heat exchanger is mounted within the V of the engine block, Bosch Motronic engine management system with full sequential fuel injection, knock control on each bank, distributorless ignition system (DIS), and closed loop lambda control.
