The Renault 15 and Renault 17 are two variations of the same coupé designed and built by French automaker Renault between July 1971 and August 1979. The R17 was sold as R177 in Italy, respecting the heptadecaphobia superstition. They were effectively coupé versions of the Renault 12. The main differences between the two cars were their headlight configuration (the 15 had two rectangular headlights whereas the 17 had four round headlights) and their rear side windows. Some markets show the 17 with the rectangular lights for TL versions. The Renault 15 and 17 were presented at the Paris Motor Show in October 1971. Underpinnings The chassis and most of the running gear came from the Renault 12, while the 1565 cc A-Type engine in the more powerful R17 TS and R17 Gordini models was derived from the engine in the Renault 16 TS. Though the mechanicals of the cars were derived from other Renaults, the body was completely new. Chronology At the 1974 Paris Motor Show, the Renault 17TS was renamed the "17 Gordini". This new name was an attempt to fill the gap left by the recently discontinued Renault 12 Gordini, nothing was changed beyond the badging. There was a minor facelift during March 1976, most noticeable on the grille of the 15, where the chrome edge surround was replaced with a body-coloured one: the headlights were enlarged and brought forward to a position approximately flush with the surround. The grille of the 17 also lost its chrome surround, although on both cars the partially chrome front bumper now curved up at the edges to roughly half-way up the height of the grille. The R15 and R17 remained in production until summer 1979 when they were both replaced by the Renault Fuego. Performance tested The British Autocar magazine tested a Renault 15 TL in November 1972, shortly after the model's UK debut. The top speed of 94 mph (151 km/h) and the 0-60 mph (97 km/h) time of 13.6 seconds put the car near the bottom of the list of competitor vehicles selected for comparison, but overall fuel consumption for the test was class leading at . The manufacturers' recommended retail price of £1,370 was slightly lower than the UK sticker price on a comparable Vauxhall Firenza Sport and Fiat 128 Coupé 1300: Ford's Capri 1300L at £1,123 massively undercut comparable cars in the UK at the time.
