Neither Nor – Renault 16

While Citroën was busy trying to develop a suitably innovative vehicle known as Projet F with a wankel motor and torsion bar suspension to fit between it’s successful small 2CV and and successful large DS models Renault’s Gaston Juchet was developing today’s featured Renault 16 with an aluminium straight 4 motor and torsion bar suspension for exactly the same market.

Like the Renault 4 launched in 1961 the 16 featured front wheel drive, umbrella stick gear change and an asymmetrical wheelbase thanks to the torsion bar suspension.

Another similarity with the smaller Renault sibling was the five door body style, neither car was offered with anything else for private use, though in the case of the 16 the rear door was noticeably more inclined toward the front.

Motoring Illustrated in May 1965 reported that “The Renault Sixteen can thus be described as a large family car but one that is neither a four door saloon (sedan) and nor is it quite an estate (wagon). But, importantly, it is a little different.”

The important neither nor word the journalist was struggling for was of course “hatchback” a term that was not coined as a body style until the early 1970’s.

European Journalists were so impressed with the Renault 16 that it became the first French car, after the Rover 2000 and Austin 1800, to named European Car of The Year in 1966.

Initially the Sixteen was launched in Grand Luxe and Super variants both powered by a 1470cc / 89 cui motor producing 54 hp.

At the 1968 Geneva Motor Show the TS version was launched with a 1565cc / 95 cui engine, an all-new instrument panel that included; a tachometer, water temperature gauge, two-speed windscreen wipers, column shift, rear defroster, passenger reading light, and optional electric powered windows.

In 1970 no less a luminary than Stirling Moss was quoted as saying “”There is no doubt that the Renault 16 is the most intelligently engineered automobile I have ever encountered and I think that each British motorcar manufacturer would do well to purchase one just to see how it is put together”.

By the time production of the facelifted Renault 16 ceased in 1980 over 1.8 million examples had been built, and most European manufacturers had a similar 5-door hatchback in their showrooms.

It is said that when the Renault 16 was launched Citroën cancelled it’s Projet F because of the similarities of the 16 and F amid rumours of industrial espionage, however these remain unfounded possibly in the light of the similarities of the Renault 4 and 16, possibly because the truth was the planned Wankel engine Citroën hoped to use could not be made as reliable as they would have liked.

Unlikely as it may seen among my earliest motor racing memories was seeing a Renault 16 being raced in Zambia at typically Gaulish angles on the corners by a chap called de Decker who tried in vain to keep up with a similarly standard Alfa Romeo 1750 GTV driven by Sergio Pavan at Nchanga.

The left hand drive non UK spec ’68 model year Renault 16 TX seen in these photographs taken in Bristol was not registered in the UK until October 2008.

Rolling Into Records – Howmet TX #2

In 1967 Philadelphian sports car racer Ray Heppenstall persuaded his friend Tom Fleming that a conventional sports car with an aircraft gas turbine engine might make a competitive racing car. Fleming, sales vice-president of Howmet a major suppliers of precision castings to the aircraft gas turbine industry, and Heppenstall in turn convinced the board of Howmet that such a program would be a great way to promote their business.

Two spaceframe chassis based on a Can Am design were built and fitted with Continental TS325-1 turboshaft motors that were donated from a batch of ten motors Continental had developed for a failed observation helicopter contract. The motors produced 330 hp and were given a 3 litre / 183 cui equivalency rating by the regulation governing FIA. In order to comply with the reverse gear regulations a separate electric motor drive was employed.

Today’s featured car chassis #2 is the second of the two Howmet’s built with a slightly longer wheel base. The week after Ray had recorded the teams first victory and the first ever for a gas turbine powered car at Huntsville, Dick Thompson repeated the feat driving #2 at Marlboro winning the SCCA Preliminary then sharing the car with Ray to win the 300 mile feature race.

In July ’68 Ray and Dick shared chassis #2 again to come home third overall and first in class at the Watkins Glen 6 hour race behind a pair of 4.7 litre / 286 cui Ford GT40’s.

Ray recorded a third place finish driving chassis #2 at Donnybrook in August ’68 before both Howmet’s were shipped to Europe for the Le Mans 24 Hours, which had been delayed until September from it’s usual June date by civil unrest and strikes involving 11,000,000 French workers.

#2 was the faster of the two Howmets in qualifying for the 24 hour endurance classic Dick and Ray qualifying 20th two seconds faster and four spots ahead of the sister machine driven by Hugh Dibley and Bob Tullis. In the race the cars were hampered on the corners because the single gear was designed to optimise performance on the 4 mile Mulsanne straight.

Dibley / Tullis were disqualified after a three hour pit stop to change a rear hub bearing for covering insufficient distance after seven hours, while #GTP2 had a faulty fuel control which restricted the cars top speed to just 100 mph. During the evening Dick lost control and rolled the car at the slightly banked Indianapolis corner.

Note the rear lights sourced from the original iteration of the Ford Cortina, according to Bob Mckee other proprietary parts used to finish the Howmet included front indicators from a Ferrari, Porsche wipers, modified Triumph steering and Mustang door latches.

Howmet withdrew their support for the project after Le Mans having determined the disadvantages of throttle lag, running the car with a single gear, absence of engine braking and high fuel consumption were insurmountable issues for competitive entries in the long run.

Ray Heppenstall rebuilt #GTP2 with open spyder bodywork and in 1970 timed by IMSA officials recorded six World Records for standing starts over 1/4 mile, 1/2 km and 1 km distances in two weight divisions for vehicles upto and over 1000 kgs. Ray’s fastest speed of 167.97 mph was recorded in the lighter division over 1 km all set on a stretch of open road adjacent to Talladega Super Speedway !

With the motors returned to Continental Ray bought the worlds only gas turbine powered race winning cars for a nominal dollar from Howmet in 1971. Chuck Haynes had Bob McKee restore #2 back into Coupé form in 1996, it is now fitted with an Allison 250C18 turboshaft helicopter motor which is lighter but with a similar power output to the original.

My thanks to Pete Stowe for additional in formation on the Hownet’s regarding the records chassis numbers and a quote from Bob Mckee on the proprietary parts used.
