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 four 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 aging straight-six engine range. These engines have a cast-iron engine block with cast aluminium alloy cylinder heads. The cylinder heads contain four 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 or 90-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 included an oil-to-water heat exchanger 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 , and closed-loop lambda sensor control....
