The Volvo 343 was introduced on 19 February 1976. The introduction model was fitted with a 1.4-litre
Renault Cléon-Fonte engine in the front and DAF's radical
Variomatic continuously variable transmission unusually mounted in the rear, helping weight distribution. The engine was an enlarged version of those fitted to the DAF 55 and 66. To add to the car's appeal and boost its sales, Volvo adapted the M45 manual transmission from the
200 series to fit in place of the CVT, and sold the manual version alongside the CVT models from 1979. Volvo had also by this point substantially redesigned the interior with a much higher quality dashboard; also new seats, steering wheels and various fittings derived from the larger 200 Series model - addressing the heavy criticism of the DAF-designed interior of the early cars. A five-door model, the 345, was added in August 1979 for the 1980 model year. The extra doors added ; other modifications included better brakes, a slightly larger track due to wider wheels, and interval wipers. The more powerful 360 GLT was only available with a five-speed manual and the engine came equipped with a
breakerless ignition system and velour interior, amongst other comfort details. The 360 GLT can be recognized by its front spoiler with integrated extra lights, a rear spoiler, and by being lower. This 2.0 L 360 model was available in five-door and three-door hatchback form, with four-door "
notchback" saloon models added in 1984. Trim levels were GL, GLE, or GLT, depending on output and specifications. In 1985, the 300 Series received a significant facelift. Other changes were (optionally body-coloured) wrap-around bumpers with integrated turn signal lights. The taillights were also redesigned. Instrumentation changed from Smiths units to VDO. The older Volvo "redblock" engines in the 360 were upgraded to the low-friction B200 unit. Capacities and outputs remained much the same. The carburetor version was designated B200K, and the Bosch LE-Jet fuel-injected version is known as the B200E. A famous advertisement for the 300 series in the late 1980s saw a
crash test dummy "come alive", and drive a 340 out of a second-floor factory window, nose-diving into the concrete ground. From 1987 on, incremental improvements in features and emissions control were made. The newly designed power steering from the new
Volvo 480 became available as an option for the 1988 model year, while rust protection was improved with the increased use of galvanised steel. Production of the 360 came to an end in 1990, while the 340 was discontinued in 1991, despite the fact it had supposedly been replaced by the
Volvo 440 in 1987. The last car of the Volvo 300 series (a white Volvo 340) rolled off the production line on 13 March 1991, three years after the launch of the 400 series. ==Engines==
