The Wolf-Williams FW05 was a Formula 1 race car, which was used in the 1976 season by the British team Walter Wolf Racing . The model was created in 1975 at Hesketh Racing as the Hesketh 308C .
The origin of the Williams FW05 lies in the British team Hesketh Racing. Founded by Alexander Hesketh racing team was first launched in 1973 as a customer team in Formula 1 and had since 1974 own cars of the type 308 used. The designer was Harvey Postlethwaite . After the team had begun the 1975 season with revised versions of the 308, it presented in August 1975 with the type 308C before a redesign. The car followed the lines of the 1974 308, but was more compact, had a modified aerodynamics and a self-contained suspension. Hesketh placed the 308C in the fall of 1975 in two races for James Huntone, who came in both attempts in the points. At the end of the year Hesketh Racing ran into financial difficulties, after which the founder retired from the racing stable. The former team manager Anthony "Bubbles" Horsley continued to operate the team on its own responsibility. In order to receive money for the coming season, he sold all copies of the 308C to the competing team Frank Williams Racing Cars .
Frank Williams ' team - the predecessor of today's Formula 1 team Williams F1 - was engaged since 1969 in Formula 1. In a few years, the racing team worked as a customer team, but from 1973 it produced its own race car, which was initially referred to as the main sponsor - the Italian car maker Iso Rivolta and the cigarette brand Marlboro - Iso Marlboro. After Williams had separated from Iso in the spring of 1975, the cars were subsequently referred to as FW 01 to 04 (FW for Frank Williams). At this time Williams was considered "starvation in Formula 1".His team was unsuccessful. The cars had a low technical level and were poorly maintained due to weak finances.
The situation changed at the end of 1975. Frank Williams entered into an alliance with the Austro-Canadian entrepreneur Walter Wolf , who took over shares of the team and provided funds for a technical start of the team. With Wolf's money Williams bought all three copies of the Hesketh 308C, which he launched in 1976 with only minor technical changes under the name Williams FW05 at the start.
After the first race of the 1976 season, the team of Frank Williams Racing Cars (Williams) was renamed Walter Wolf Racing; however, the vehicles retained the designation Williams.
The designer of the car was Harvey Postlethwaite. The car had a flat aluminum monocoque, which in the first version was too weak and tended to twist. After initial test drives, reinforcements had to be retrofitted. The front end pointed towards the front towards the bottle neck. The coolers were housed in the back of the side boxes. The first copy of the car had a very narrow track. It should improve the aerodynamics, but deteriorated the handling. After the test drives, the track was widened. The second car was built from the beginning with a wider track. The front suspension consisted of wishbones with extremely short upper rocker arms, compared to Ferrari, the suspension was extremely small in size. The rear brake discs were inside, right next to the gearbox.
A special element of the car was the so-called Aeron rubber suspension on the front axle. Postlethwaite had designed the chassis - originally based on a suspension made of titanium coil springs - also for a rubber suspension / shock absorber unit on the front wheel. The rubber suspension should save weight and be easier to handle. Williams took on this design unchanged for t 1976
The drive was a Cosworth DFV eight-cylinder; the power transmission took place via a Hewland FGA-400 five-speed gearbox . The curb weight of the FW05 was given in early 1976 at 595 kg, 15 kg more than the Hesketh 308C had at its introduction. The tank contents of the three tanks - indicated with 182 liters was - two side, one behind the driver's seat.
Frank Williams' longtime partner Patrick Head reworked Postlethwaite's design in winter 1975/76 in some detail. He considered the car unfit and later explained that he did not learn how to design race cars based on the 308C or FW05 . Hesketh produced three chassis of the 308C in the fall of 1975.The chassis no. 308C / 1 was built in the 1975 season. It was the only copy of the 308C that was completed by Hesketh. James Hunt drove this car in 1975 in two Formula 1 races.From the chassis no. 308C / 2 1975 only single parts originated. The completion took place only in the spring of 1976 at Williams.The third chassis (No. FW05 / 3) was completed by the Williams mechanics only in early summer 1976 from spare parts.
The Williams FW05 were used in the Formula 1 World Championship. The team Walter Wolf Racing, which had emerged from the year 1975/76 from Frank Williams Racing Cars, brought in 1976 at times two copies of the FW05 at the start. The regular driver was initially Jackie Ickx . He predominantly drove the chassis 308C / 1 already used by Hunt last year. Ickx finished four times. His best result was seventh place in the Spanish Grand Prix . This was also the team's best result this year. The race result was faced with four missed qualifications of the Belgian. After the Grand Prix of France , he was subsequently replaced by Arturo Merzariowho regularly qualified with the newly built FW05 / 3. Merzario, however, never came to the finish. For all six attempts he was out prematurely; in two cases this was due to driving mistakes Merzarios.
The second vehicle (chassis 308C / 2) reported Wolf seven times for Michel Leclère . Leclère came five times to the finish; his best result was the 10th place in the Spanish Grand Prix. Before his home race , the team
In 1977 and 1978 , two FW05s were used in the British Aurora FX series . The drivers were Derek Cook and John Cooper .
