the 750, many more 750 vans were produced. 750 The next evolution of the Rebel was the 750 model, introduced in October 1972. This car gained some parts with the three-wheeled Reliant Robin that was due to be introduced in 1973, parts gained were: The new 748cc engine Rear light clusters Modified version of the 4 speed all sycro gearbox Radiator The Rebel 750 was the most popular Rebel as Reliant gave the Rebel a big marketing push in magazines and newspapers including full-page colour ads, because of this many people were only discovering the Rebel for the first time now with its large range of models. The interior also had a large change, fatter more comfortable front seats were used with a soft touch padded dashboard, all the interiors now used black vinyl seats and black carpets. Van production saw a short-lived effort to produce more as Royal Mail needed a replacement for its fleet of Morris vans, they had already trialed the Reliant Supervan but thought the more conventional Rebel van would be a good replacement, only as little as 10 vans were trialed. In early 1974 with the new Reliant Robin proving to be so popular production on all other models including the Rebel, Bond Bug, Reliant TW9 ended so more Robin models could be made. In 1975 the Rebel would be replaced with the Reliant Kitten. Estate legacy The Reliant Rebel estate was the first time Reliant would build a small estate vehicle using a large side hinged door with fold-flat rear seats. Owing to the popularity of this design, Reliant would carry on using this formula for the Regal, Robin and Rialto models until 1998. Engines The Rebel used all of Reliant's own all aluminium OHV engines (based on a reverse-engineered 803cc Standard SC engine used in the discontinued Standard Eight). The car was launched with a 598cc engine producing 28 horsepower, this was 4 more horsepower than standard 600cc from the regal 3/25, this was done as the car felt sluggish with its extra weight. After the introduction of the 70 mph speed limit on British motorways the new speed limit was seen as a target, any vehicle with a top speed lower than 70 mph was seen to be slow, with this Reliant increased the engine size to 701cc and 31 hp, the new engine was then used in both the Rebel and
