Paddle up

The paddle-operated transmission has come a long way. What began as an infuriating gimmick that hindered the likes of the first Aston Martin Vanquish and the Ferrari 575M has morphed into a highly competent, capable system many consider an essential facet of the modern supercar.

And when it comes to the mastery of said system, few can hold a candle to Ferrari. The 296 GTB’s eight-speed double-clutch transmission is one of the very best in the business, while the ‘F1’ gearbox (first seen in the F355 in 1997) has the distinction of being the very first road-going paddle-operated transmission, its name a clear reference to the Scuderia’s on-track breakthrough from eight years prior.

The 1989 season saw an end to turbocharging in Formula 1, a rule change that spawned a flurry of naturally aspirated eight, 10, and 12-cylinder motors, all with narrower power bands than their turbocharged predecessors requiring quicker gear shifts to keep them on the boil. The grid was left scrambling for a solution, and it wasn’t long before one was devised.

The brainchild of Ferrari’s technical director, John Barnard, the sport’s first semi-automatic gearbox was born. Curiously the prime motivation behind it was  not faster shift times but improved packaging. Barnard figured out that the space-inefficient gear linkage connecting the driver to the gearbox could be replaced with a paddle-operated electrical signal, allowing the drivetrain to be packaged more tightly, thus improving aerodynamics.

The result was the 640, the Scuderia’s first new Grand Prix car since the passing of Enzo Ferrari in 1988. With Nigel Mansell and Gerhard Berger on driving duty, the 640 managed an emphatic debut win at the season opener in Brazil, Mansell coming home some 7.8 seconds ahead of eventual World Champion Alain Prost. But despite its early season promise, the 640 would turn out to be a frustrating misfire. Ferrari may have racked up three wins and nine podiums that year, but chronic unreliability and six double DNFs denied the team any title chances.

Yet despite that fragility in its early life, the benefits of the semi-automatic transmission were clear for all to see. The final manual gearbox was killed off just six years later, the paddle shift having morphed into an indispensable fixture in Formula 1.

But what if I told you there was another? An alternate starting point? One that predated Barnard’s efforts by nearly a decade and, were it not rejected by one man, could have changed the face of F1 very much sooner? For that, we must spool back to the very end of the 1970s and the work of one Mauro Forghieri.

In contrast to 1989, turbocharging was becoming increasingly commonplace in Formula 1 at the end of the previous decade, but with it came enormous turbo lag, a highly undesirable trait in urgent need of mitigation. In 1979 when Ferrari was starting work on its own turbo motor, Forghieri – widely regarded as one of the most influential figures in the history of Ferrari – began work on a semi-automatic transmission, one he believed could slash shift times and negate the pitfalls of forced induction. A high-pressure hydraulic system was developed bearing a strong resemblance to systems used by the aviation industry, and linked to push buttons on either side of the steering wheel.

Obscure though it may seem, Forgheri’s efforts yielded significant track time. The then-current, title-winning 312 T4 was fitted with the semi-automatic gearbox and, with the great Gilles Villeneuve at the helm, completed 100 trouble-free laps around Fiorano after the end of the 1979 season.

"Despite the fragility in its early life, the benefits of the semi-automatic transmission were clear for all to see. The final manual gearbox was killed off just six years later, the paddle shift having morphed into an indispensable fixture in Formula 1"

To those who witnessed it, the days of the manual gearbox in F1 must have seemed numbered to say the least. Or rather, they would have done were it not for the verdict given by Villeneuve himself. According to Forghieri, the Canadian bemoaned the loss of a manual gearbox, stating that ‘a steel shift lever will always be more reliable than electronics’.

Famed and feared for his treatment of drivers, of all the racers he employed in his autumn years it was Villeneuve to whom Enzo Ferrari was closest, his flamboyance and unwavering commitment reminding him of Tazio Nuvolari, in Enzo’s eyes the finest driver of them all. Gilles’ word was all it took for the Old Man to scrap the project. The following year’s disastrous 312 T5 made do with three pedals and a stick.

John Barnard deserves every bit of the praise he has received for moving the sport on in such a fundamental way. But Mauro Forghieri’s would-be breakthrough remains a fascinating what-might-have-been, one that makes you realise that while Enzo Ferrari may not have been any kind of wizard ingegnere as he liked to be described, when it came to recruiting them to his team, he was one of the greatest there has ever been.

Andrew wasn't immediately a fan of the F355's F1 gearbox

When paddles arrived in showrooms, by Andrew Frankel

I never expected to like the Ferrari F355 with the ‘F1’ robotised manual transmission, replacing as it did one of my favourite six-speed gearboxes. To me part of the joy, even the mystique of driving a Ferrari was to hear every click, clack and scrape as you manhandled an alloy ball on top of a slender stalk around an exposed gate.

Then I drove the two-pedal F355 and found it met my expectations precisely. On the road the shifts were slow and, if you didn’t lift the throttle, notably jerky too, making you look like an amateur in front of your passenger.

But slowly it grew on me: if you timed the changes properly you could make it as smooth as the standard car, but the best bit were downshifts on the race track where you could either left foot brake and stab the throttle to rev-match each shift, or just heel and toe. If you were anywhere close it would sound and feel brilliant.

No, I’d never have chosen one over the manual, but I did see there was enormous potential if somehow the changes could be made smoother and swifter. Of course I didn’t figure that the key was to have the next gear already in mesh just waiting to be engaged, just like they used in pre-selector transmissions before the war. And, as you know, the solution lay not in perfecting the robotised manual, but introducing the dual-clutch gearbox. And the rest, as you know, is history.
