1968-1970 Vauxhall Viva HB Estate 1600 (84 Hp)

The Vauxhall Viva HB Estate 1600, produced between 1968 and 1970, represents a practical and affordable family vehicle from British manufacturer Vauxhall. Part of the second generation of the Viva (HB), the Estate model offered increased versatility compared to the saloon, catering to the growing demand for vehicles capable of carrying both passengers and cargo.

It was a key part of Vauxhall’s strategy to provide economical transportation to a wider audience.

Vauxhall Viva HB Estate: A Detailed Overview

The Viva HB Estate was designed to provide a cost-effective and reliable mode of transport for families. Its estate body style, with a rear tailgate, offered a significantly larger cargo area than the standard saloon, making it ideal for holidays, shopping, or transporting work equipment. The 1600 variant, equipped with a 1.6-liter engine, provided a reasonable balance of performance and fuel economy for the era. The car’s simple mechanical design made it relatively easy to maintain, contributing to its popularity among budget-conscious buyers.

Engine & Performance

The heart of the Viva HB Estate 1600 is a 1.6-liter (1599 cm³ or 97.58 cu. in.) inline-four cylinder petrol engine. This naturally aspirated engine produces 84 horsepower (Hp) at 5800 rpm and 122 Newton-meters (Nm) of torque at 3200 rpm, which translates to 89.98 lb.-ft. The engine features an overhead camshaft (OHC) valvetrain and a compression ratio of 8.5:1. Fuel is delivered via a carburetor. The power-to-weight ratio is a respectable 10.6 kg/Hp, or 94.7 Hp/tonne, while the torque-to-weight ratio stands at 7.3 kg/Nm, or 137.5 Nm/tonne. Power per liter is rated at 52.5 Hp/l. Power delivery is relatively smooth, making it suitable for everyday driving. The engine is coupled to a four-speed manual transmission, which drives the rear wheels. Performance figures were modest by modern standards, but adequate for the time, prioritizing fuel efficiency and reliability over outright speed.

Design & Features

The Vauxhall Viva HB Estate is a three-door station wagon (estate) with seating for five passengers. Its design is characterized by a boxy, utilitarian shape, typical of cars from the late 1960s. The estate body style extends the roofline rearward, creating a larger cargo area accessible through a rear tailgate. The car’s exterior styling is relatively simple, with minimal chrome trim. Inside, the cabin is functional and spartan, reflecting the car’s affordable price point. Features were limited compared to modern vehicles, but included basic instrumentation, such as a speedometer and fuel gauge. Safety features were also rudimentary by today’s standards, consisting primarily of seatbelts. The focus was on providing a practical and reliable vehicle at a low cost. The trunk (boot) space offers between 526 liters (18.58 cu. ft.) with the rear seats up and a substantial 1522 liters (53.75 cu. ft.) with the rear seats folded down, showcasing the estate’s versatility.
