Nico and Lewis may or may not have settled their feud, but in years past there have been quite a few in Formula One.
10. James Hunt vs Riccardo Patrese
When Riccardo Patrese started his F1 career he was a much wilder driver than the steady hand who ended his career at Williams and Benetton. At the start of the 1978 Italian Grand Prix, Patrese was judged to have caused the pile-up that caused Ronnie Peterson's accident. Although the Swede's injuries were not life-threatening he died in hospital from an embolism overnight.
With pressure from Hunt, the Grand Prix Driver's Association banned Patrese from the following race, the United States Grand Prix. Hunt retired and became the BBC grand prix pundit alongside Murray Walker in the commentary box, but he never lost any opportunity to criticise Patrese with barbed asides whenever he did anything wrong.
9. Nigel Mansell vs Nelson Piquet
Nigel Mansell had already spent a season at Williams in 1985 when double world champion Nelson Piquet arrived for 1986. The Brazilian reputedly expected number one status at the team. He described Mansell as an uneducated blockhead and also aimed some pretty low-blows at Mansell's wife Roseanne, who, unlike many drivers on the grid, had supported him all the way through the hard times of junior formulae. Mansell was not deflected by the mind games and although neither won the 1986 shoot-out in Adelaide, Nigel exacted one of the most convincing and humiliating defeats of a team-mate in the 1987 Silverstone GP, hauling back 28 seconds in 30 laps which included the legendary pass into Stowe.
8. Ken Tyrrell vs Jean-Marie Balestre
Frank Williams and Ron Dennis are the last surviving 'garagistas', the independents who came up and beat the factory teams. In the 70s, 80s and 90s there was also Ken Tyrrell. 'Uncle Ken' was part of the awkward squad; team bosses who held the FIA (FISA) to their word. In the 1980s while everyone else was acquiring turbo engines, Tyrrell soldiered on with the Cosworth DFV. By the 1984 season his cars were seriously underpowered but he stood a chance at the less power-hunger circuits such as Monaco and Detroit.
After Martin Brundle had finished in an exhilarating second place at the 1984 USGP in Detroit, the FIA found impurities in the water injection system on his Tyrrell 012. The team was disqualified from the remainder of the World Championship and lost the 13 points they had won. Many in the paddock believed that the despotic FISA (FIA) boss Jean-Marie Balestre (seen in the Senna film) wanted to make an example of Tyrrell and pay him back for being an uppity garagista. Balestre was like that.
7. Ecclestone vs Silverstone and the BRDC
Bernie Ecclestone's traditional enmity in the late 1990s and early 2000s was reserved for the Silverstone circuit owned by the 'old boy, blazerish' British Racing Drivers Club. Bernie never lost any opportunity to have a go at the lack of investment at the circuit and was always threatening to take the British Grand Prix away. At one time he looked to place the GP at Brands Hatch but the facilities couldn't be expanded due to planning restrictions. Donington got the GP but couldn't come up with the investment to improve the track.
The low point of the feud came in 2000. Helped by FIA boss Max Mosley , Silverstone was given a ludicrous April slot on the calendar for the 2000 race. Britain in April can have snow, frequently has long periods of rain and occasional flooding, so that date was never going to work. When the GP came, the grass field car parks proved wholly inadequate and getting to and from the race proved to be a muddy nightmare
6.Fernando Alonso vs Ron Dennis
Ferrari's spygate took a new twist thanks to Fernando Alonso's insistence that he be treated as the McLaren team's No.1 driver and that they should give him priority over Lewis. Matters got to such a head that during qualifying for the Hungarian Grand Prix Alonso refused to move his car out of the pitbox and prevented Hamilton going out for a final run in qualifying - this after Hamilton had ignored a request for the cars to switch position on track (it should have been Alonso out last).
When Alonso then threatened to go to Max Mosley with information that McLaren knew all about the dossier that Mike Coughlan and Nigel Stepney had collected in Spygate, Ron Dennis was compelled to tell Max Mosley himself. Alonso believed that McLaren wanted Hamilton to win the World Championship, a position made worse by Ron describing Alonso as "the other car" in a way that made it sound like he was driving for a rival team. Alonso left the team at the end of the season.
5. Max Mosley vs Ron Dennis and McLaren and Rupert Murdoch's newspapers
After the revelations of Spygate, Max Mosley hauled the McLaren team over the coals for possessing the "dodgy Ferrari dossier" even though there was no hard evidence that McLaren had copied any system of the 2007 Ferrari.
McLaren were investigated by the FIA and given an eyewatering $100 million fine. Renault were also found guilty of possessing McLaren Intellectual Property but were let off. When Martin Brundle drew attention to the apparent inconsistency in this, the FIA sued the Sunday Times in which Brundle's column appeared.
A year later Max Mosley was uncovered by a News of the World report as participating in sado-masochistic sex acts with five consenting women and subsequently sued them for a breach of his privacy. This precipitated his ultimate removal as FIA president.
4.Sebastian Vettel vs Mark Webber
Mark Webber didn't like Sebastian Vettel right from the time that he crashed into the back of him at the 2008 Japanese Grand Prix, when they were running behind the Safety Car. Back then, Vettel was in the Toro Rosso, and the German ruined what could have been Webber's debut Red Bull win.
The 2010 World Championship was Webber's to win, but poor qualifying, 0.5 slower than Vettel, at the final race in Abu Dhabi ruined Mark's chances. In fact, he still would have won that year had Vettel not crashed into him while attempting to grab the lead at the 2010 Turkish GP. Vettel also hit Jenson Button in a similar manner at the 2010 Belgian GP.
The 'Multi 21' affair at Malaysia in 2013 only cemented what was a long-standing dislike after which Mark announced his retirement.
3. Didier Pironi vs Gilles Villeneuve
One of the most dramatic last laps in the history of F1 was the final lap of the San Marino Grand Prix at Imola in 1982 when Ferrari team-mates Didier Pironi and Gilles Villeneuve were entertaining Ferrari's home crowd. Villeneuve thought there was an agreement in place that if he was leading on the final lap, that Pironi would hold station behind to ensure a 1-2 for the adoring tifosi.
When Pironi overtook Villeneuve, he thought at first that it was a bit of showboating for the crowd and overtook him back. But when Pironi nicked the win Villeneuve was furious and wouldn't speak to Pironi. At the following race, the Belgian Grand Prix at Zolder, Villeneuve was killed in practice and the dispute never resolved. Pironi broke both legs at the Canadian Grand Prix and couldn't finish the season, which was won by Keke Rosberg with the lowest number of wins for any World Champion.
2. FOCA vs FISA
Less of a feud, more like a war. In the past Bernie Ecclestone was able to organise the teams (FOCA) to get greater control over F1's finances and the rulebook. He was opposed by the equivalent to today's FIA, FISA, and their pompous, power-wielding boss Jean-Marie Balestre. There was talk of breakaway series and strikes, but eventually they reached a compromise to continue with F1. Bernie, abetted by his lawyer/friend Max Mosley learned a lot in the affair and one day poacher would turn gamekeeper.
1.Alain Prost vs Ayrton Senna
Although the Prost vs Senna showdown is typically played out as the two Championship-deciding races at Suzuka, the problem really started back in 1989 at Imola. This was the race in which Gerhard Berger's Ferrari had gone off the road in Tamburello and the world watched in shock as the Austrian was rescued from a fiery inferno. The race had to be restarted.
Before the race Prost and Senna had struck an agreement - suggested by Senna - that whoever led into Turn One would win the race. On the re-start Prost got the better start and led into Turn One, but then got overtaken by Senna at the Tosa hairpin. Prost was angry that Senna had cheated him but Senna maintained that the agreement was only for the first start and didn't count for the second.
