Cheapest car in the Vauxhall range is the basic two-door Viva. De Luxe and SL Vivas are available as saloons with two or four doors, or as three-door station wagons. Normal power unit is 1,256 c.c. but SL cars can be ordered with the GM automatic transmission and then have an engine of 1,759 c.c. All cars have underbody sealing and matt black wipers with intermittent action. Surprise for the 1975 Motor Show is the low-cost two-door Viva "E" which comes with the 1256 cc engine only and uses the fastback Coupé body that is identical in shape to the two-door Magnum. Vivas are noted for liveliness and low fuel consumption, and are extensively anti-corrosion treated. Estates have fastback bodies.
Using the same bodies as the Viva saloon and the former Firenza Coupé, Vauxhall have created compact well-finished performance cars with a choice of 1.8 or 2.3-litre engines. Anti-roll bars at front and rear give secure cornering, four headlamps ensure adequate night vision, viscous fan coupling, double-skinned silencer and two-piece propeller shaft cut noise and vibration. Bumpers and side mouldings are rubber-faced. Magnums come in two and four-door saloon, two-door Coupé, and three-door Estate form, with choice of 1.8 or 2.3-litre engines. The Magnums are 'plus' cars with deep cloth seats, rev-counter, four headlights etc. For 1976 the 1800 has a new cylinder-head and carburettor which increases the power-output some 11 bhp. The 2300 Magnum has a modified cylinder-head and a single carburettor which improve economy. Both cars are livelier, and are available with manual or fully - automatic transmissions. Heated rear windows and front seat belts are standard.
VAUXHALL MAGNUM ESTATE
Sleek three-door estate cars are featured in the Magnum line, with a host of refinements and a wide choice of colours. The carburetter receives hot and cold air, mixed thermostatically for exactly the right temperature. Suspension is developed from that of the former Firenza Sport. The steering wheel has a soft leatherlike covering, front seats have reclining backrests, inertia reel belts are standard.
Lean lines, with a hint of the fluted radiator that identified Vauxhalls half a century ago enclose a thoroughly modern interior which has been extensively revised since the Victor first appeared. Other improvements include stiffer cylinder blocks, new gear ratios, quieter gearbox casing, quieter exhaust, stronger differential, and pressure limiting valve for rear brakes. VX 4/90 has the 2300 engine with twin carburetters giving 116 b.h.p. Victor saloons have four doors, and the Estate has five, both models being available with the choice of Vauxhall's two overhead camshaft engines, the 1800 or 2300. All-round visibility is a strong feature of all Victors with the big glass area. Radial-ply tyres and a heated rear window are standard equipment. The Victor saloon is a very commodious car, seating five in comfort, and the Estate has a folding rear seat which transforms the rear of the body into a vast load-carrying area. Four-speed manual or three-speed/ torque-converter 'Strasbourg' automatics are available.
Numerous improvements have been made to body and mechanical parts since the Ventora was introduced early in 1972, Gearbox and differential are stronger, changes to dampers and suspension bushes give a better ride, seats are more comfortable and the instrument panel has been redesigned. With a 3.3-litre six-cylinder engine in the same saloon or station wagon bodies as the Victor, performance is outstanding.
No change for the sportsman's edition of the Victor, which with 2.3-litre twin-carburettor overhead camshaft engine is lively as well as luxurious. There are plenty of instruments on the facia for the sport-orientated driver, and inertia-reel seat belts are standard. The four big doors make the VX4/90 a good family car, and the huge boot will accommodate all the holiday baggage. The distinctive grille and sports road wheels pick out this top-of-the-range four-cylinder model. The steering wheel is leather-covered, and the bumpers have rubber inserts to guard against minor knocks.
Already familiar on the race circuits, the Competition Firenza is now being developed to give startling performances. The roadgoing model has light alloy wheels with Avon Safety rims to prevent the tyre peeling off after a blow-out. Special camshaft, larger valves, new manifolds and a lighter flywheel help the 2.3 litre engine to produce 131 b.h.p. and a ZF five speed gearbox makes the most of it.
