company Oettinger and released in 1979. The 343 Oettinger was available in red or silver metallic. A total of 125 cars were produced. A van version also entered production. The van was essentially a five-door 340, but with the rear doors replaced with full body-coloured metal pieces and with the rear seats removed. A glazed version was also available. The cargo compartment has a flat floor and a metal bulkhead behind the front seats to protect occupants from moving loads. It was called "Volvo 345 Van" and was developed for commercial use at the behest of the Dutch Postal Services, who preferred a Dutch-made vehicle. It was first presented at a commercial vehicle show in Amsterdam in February 1982 and was also offered to the public. The only engine was the petrol B14, combined with either the CVT or a four-speed manual. The Millionaire edition was introduced in 1988 to commemorate the production of the one-millionth car in the 300 series. Available on both the 340GLE and 360 GLE/T, the Millionaire featured all options including air conditioning, electric front windows and mirrors, alloy wheels, and leather interior. Prototypes There are variations of the Volvo 300 series that never made production: The Volvo 340 estate and a convertible were both built as design studies, but neither was put into production. The convertible version of the Volvo 340 was mooted, but only exists as a clay model. The 363 CS was short for 'Competition Services', to indicate a high-performance version. The 1977 363 CS was based on the three-door bodyshell and fitted with the B27F 2.7 L V6 PRV engine as used in the Volvo 260 series. The gearbox was a five-speed Alfa Romeo unit, as Volvo did not have a suitable design which would fit a transaxle-design. One prototype was built which was painted in metallic silver with black and orange 'Starsky and Hutch'-style stripes down both sides. Flared wheelarches and orange-painted, multi-spoke alloy wheels were also added to complete the sporty look. At the 1979 Geneva Motor Show, Bertone presented a three-door hatchback coupé concept on 343-basis called the Volvo Tundra. The angular design was by Marcello Gandini and continued the themes developed for the Reliant (Anadol) FW11. In motorsport The 300-series was campaigned in motorsport. A heavily modified version using Alpine/Gordini cross-flow engines bored out to 1770 cc was driven by Per-Inge Walfridsson to win the European Championship of
