This year was also the first in which a CFRP rear impact crash structure was fitted, albeit one year ahead of the FIA requirement. Spare space within the gear case may be used to accommodate oil for the engine, the gearbox if it is dry-sumped, the hydraulics, and the mandatory catch tank. He had created a seven-speed gearbox with an automatic clutch. Ferrari 640 was the first F1 car using a semiautomatic sequential gearbox 1989 in the Brasilian GP. The transmission that it was mated to, however, attracted more attention, as it contained the very first 7-speed semi-automatic gearbox seen in F1. Machining the titanium plates required considerable investment in CNC machine tools, but otherwise John claims this approach is not more expensive than traditional techniques. Ferrari had been working at a sequential semi-auto (or manual-hydroelectric activated gearbox) for many years, and had several iterations that were built and ran. All cars must be fitted with a reverse gear to comply with the FIA regulations, and reverse is operated using a button on the steering wheel which engages an intermediate gear between the gearbox input and output shafts to reverse the direction of rotation of the output shaft.Since the Ferrari 640 F1 showed the performance benefits of semi-automatic gearboxes back in 1989, all F1 teams adopted that idea.
This being another product of Barnard's quest to improve packaging, with the conventional spring and damper arrangement set to disturb the 640's lines, something that was both aesthetically and aerodynamically unsettling to him.As such, he set about finding a way to repackage the suspension in order for it to offer the same, if not better handling characteristics.

"I looked at a transverse layout, to see if I could line up the bearings of the gear shafts and final drive/differential into planes and move the weight ahead of the rear wheels. The car was designed by John Barnard, and it was the first Ferrari he was responsible for designing. Ferrari Online Store: Apparel, accessories and merchandise by Ferrari. But 1989 witnessed a car, the Ferrari 640, that was just as important for shaping F1's future technology, even though it suffered a fair share of hiccups along the way.This day on that year was another classic example, as the car proved quick at the United States Grand Prix but would suffer yet another retirement with a recurring alternator problem.Put simply this was a case of famed technical director John Barnard pushing the boundaries over what was possible in F1. Another new era began in 2019 with the launch of the new SF90 Stradale and Ferrari Roma models, which feature a fresh eight-speed dual-clutch gearbox, more compact and lighter than its seven-speed predecessor.
Founded by Mike Hewland in 1957, Hewland Engineering invented the bespoke racing car gearbox and it has supplied the worlds racing car constructors ever since.John has never been particularly happy with cast magnesium, and had already got rid of it for uprights back in 1975, on the Parnelli Formula 1 car. With 4 years of successful experience of the CFRP/titanium gearbox construction under his belt, John decided to take the next step when he joined Arrows to design their 1998 car. [citation needed] In 1989, then-Ferrari engineers and designers John Barnard and Harvey Postlethwaite created a paddle-shift semi-automatic gearbox for use in the Ferrari 640. Despite problems in testing, the car won its first race at the hands of Nigel Mansell. Nigel Mansell won on the car's debut in Brazil and would add a victory in Hungary later on, while Gerhard Berger would triumph in Portugal.However, its impact on the sport is perhaps as far reaching as the carbon monocoque that Barnard created for the McLaren MP4 before it, as fragments of the 640's DNA are heavily intertwined with the cars raced today. The car scored 39.5 points of the teams 55.5 points in 1991 with 8 podiums and finished 3rd in the constructors championship.
