Brissonneau and Lotz until it was withdrawn in 1968. Upgrades In October 1959, ready for the 1960 model year, the Floride, along with the Renault Dauphine, appeared with significant suspension improvements. The new suspension was conceived by the by now almost legendary automotive engineer Jean-Albert Grégoire and baptised by Renault "Suspension Aérostable", being intended to improve the car's ride and road holding. The addition of extra rubber springs at the front reduced roll and auxiliary air spring units (mounted inboard of the conventional coils) at the rear gave the rear wheels a small degree of negative camber and increased cornering grip. In March 1962, the Caravelle received a new 956 cc engine that would be also used by the new Renault 8 from June. Although the new "Sierra" series five-bearing engine shared no components with the existing 845 cc Dauphine engine, it was conceptually very similar: the engine size was chosen in order to come in (slightly) below the top of the 5CV car tax band in France. It had a sealed cooling system as well as a new front suspension, new rear geometry, new steering, and a new gear linkage. Moving the radiator behind the engine also freed up an extra 12 cm of space behind the front seat. Maximum power output increased to . Four-speed transmission, already included in the price at no extra cost on some export markets, now came as part of the standard with the new engine even for French buyers, although bottom gear still made do without synchromesh. The upgraded cars, first presented at the 1962 Geneva Motor Show, now featured disc brakes on all four wheels: the Floride was the first French volume car to benefit from this enhancement which also reduced unsprung weight by approximately 6 kg. The Caravelle name also replaced the Floride name in all markets from 1962 onwards. In 1964, another R8-derived engine of 1108 cc was introduced to the Caravelle, producing . This model was tested by the British "Autocar" magazine in November 1965. The car had a top speed of and accelerated from 0- in 17.8 seconds. An "overall" fuel consumption of was recorded. The Caravelle's performance closely matched that of the contemporary Triumph Spitfire 4 under most headings, though the Spitfire was a couple of mph ahead on top speed. The British car market was still protected by tariffs at this time, but even allowing for
