the update was regarded as successful although retrospectively some of the purity of the lines of the early car were lost. At a time of rising fuel prices, the need for fuel efficiency was becoming paramount, and Opel decided to change the engine specifications of the Monza. This meant introducing both the inline four-cylinder CIH 2.0E engine from the Rekord E2 (replaced by the torquier 2.2 in October 1984). However, as the Monza weighs almost 1400 kg, given the 115 PS of the two engines, the cars were underpowered and thus unpopular. The 2.5E was given a new Bosch injection system so between 136 and 140 PS was available. The 2.8S was taken out of production. The 3.0E engine stayed the top of the range. The 3.0E was given an upgraded Bosch fuel injection and fuel consumption improved somewhat. The cars now came with more luxurious interior, electrically controlled side mirrors and even an on-board computer, recording fuel consumption, speed and range. The launch of the A2 in the UK saw the demise of the Vauxhall Royale Coupe, which had been sold alongside the Monza, resulting in only the Opel model being available on the market. The Royale was disparagingly described by Autocar as "an effeminate, frilly, titivated version of the [Monza] with fussy wheels and an unpleasant (often pastel-shaded) velour-smothered interior". Monza GSE The last incarnation of the Monza was the GSE edition in mid-1983; basically the A2 car, but a high-specification model which had Recaro sports seats, digital LCD instruments, firmer suspension, the Getrag five-speed manual transmission, an enhanced all-black interior, and a small boot spoiler. Also GSE models are equipped with a 40% limited slip differential, an addition that had to be ordered separately on earlier 3.0E cars when purchasing. By the time the Senator was updated to the new Senator B and the Monza cancelled, 43,812 Monzas had been built. There was no direct Monza replacement, although the idea of a large Opel/Vauxhall sporting car was carried on in the Lotus Carlton/Lotus Omega saloon. Bitter Cars put a 4.0 engine under the hood as a prototype. Three were built; two left hand drive and one right hand drive, one left hand drive burned out on a motorway in Germany and the other is in a museum, but the right hand drive one is in Somerset, UK.
