Manta had more "sporty" styling, including a droop-snoot nose not seen on the Ascona, which was similar to the UK equivalent of the Ascona, the Cavalier Mk1. The Vauxhall equivalent of the Manta was the Cavalier Mk1 Sports Hatch and Cavalier Mk1 Coupe. Up until 1981, Vauxhall models were sold in continental Europe alongside Opel in 11 countries, resulting in the Vauxhall Cavalier Mk1 Sports Hatch and Coupe, as well as the saloon equivalent of the Ascona B, competing against each other. Engines were available ranging from the small 1.2-litre OHV engine, the 1.6-litre CIH and the 1.9-litre CIH. Also in 1976, the GT/E engine from the Manta A series was adapted into the Manta B programme spawning the GT/E Manta B series. In 1979 the GT/E had the engine replaced with the new 2.0 litre CIH (actually an overhead cam design, but based on the CIH block) and with a new designed Bosch L injection system. Power output was now . The 1.9-litre engine gave way to the 2.0 litre S engine which was aspirated by a Varajet II carburettor. This engine was the most used engine by Opel at the time, and was to be found in several Opel Rekord cars. Opel also offered a dealer-installed tuning kit for the fuel-injected engine, promising at least thanks to a modified camshaft, valve lifters, and exhaust system. The B series Manta fitted 185/70R13 Pirelli Cinturato CN36 tyres on 5.5" or 6" wide 13" wheels. In 1977, a three-door hatchback version appeared to complement the existing two-door booted car. This shape was also not unique, being available on the Vauxhall Cavalier Sports Hatch variant. Both Manta versions received a facelift in 1982, which included a plastic front spoiler, sideskirts for the GT/E and GSi models, a small wing at the rear and quadruple air intakes on the grille. Also the 1.2-, 1.6- and 1.9-litre engines were discontinued and replaced by the 1.3-litre OHC engine, the 1.8-litre OHC and the 2.0-litre S and E CIH engines (although the 75 PS 1.9N continued to be available in a few markets). The GT/E was renamed and was called the GSi from 1983 (except in the UK where the GT/E name continued). Production of the Manta continued well after the equivalent Ascona and Cavalier were replaced by a front-wheel-drive model "Ascona C". The Vauxhall Cavalier Mk1 Sports Hatch and Coupe did not continue past 1981,
