In 2011, Group Lotus and Tony Fernandes continued their fight over naming rights, and following a ruling in May the Malaysian team could continued using the "Team Lotus" name and Team Lotus roundel, but could not use "Lotus" on its own.
The ruling also confirmed Fernandes as the owner of the Team Lotus name, having bought the rights to the name from David Hunt. However, the court ruling stated that Group Lotus had sole right to use the name "Lotus" on its own, and could enter Formula One using "Lotus" for a team name, the black and gold livery, and the Lotus roundel.
Consequently, in 2012 the Enstone team - formerly Toleman, Benetton, Renault and Lotus Renault GP - raced as Lotus F1 Team, while Fernandes outfit will competed as Caterham F1 Team.
In late November 2011, Lotus F1 Team announced that it had been informed by Robert Kubica that he was unable to commit to driving for it in 2012. Days later, the team announced that it had secured the services of 2007 world champion Kimi Raikkonen, the Finn returning to F1 after an absence of two seasons. A couple of weeks later, despite Vitaly Petrov having a valid contract, Romain Grosjean was confirmed as Raikkonen's teammate.
After 300 Grands Prix, 2012 saw Renault with a new name, a new driver line-up and new ambitions. While one applauded the team for its (failed) experiment in 2011, one had to wonder if it wasn't taking another enormous risk in terms of Raikkonen, while there were those who also doubted Eric Boullier's abilities as a team boss.
Right from the outset the E20, named in honour of Enstone the HQ of Benetton and then Renault, was good. Not Red Bull good but good enough to give the McLarens and Ferrari(s) a run for their money.
Despite the lack of budget, certainly compared to the big guns, the (now) British team was one of the front-runners.
Scoring points in every round and Kimi Raikkonen completing all but one of the season's 1192 laps is an indicator of how good the E20 was. Indeed, had it not been for the errors of Grosjean the team might have finished third in the championship ahead of McLaren and Mercedes.
Good looking cars don't always perform well but in the case of the E20 it did, though a lot of the credit, other than James Allison and his team, must go to The Iceman, who was even quicker (and moodier) than we remembered him.
An Enstone car is always going to provide a little controversy and this time around it was the car's suspension which attracted attention. Better on a Sunday than a Saturday the E20 was also better suited to warmer conditions.
In Bahrain it was widely felt that Raikkonen could have pushed Vettel a little harder but then again it was too easy to forget that this was no longer a works team and that the Finn had been away for two years. It was widely seen that an Iceman win was a matter of when rather than if but as the season wore on one tended to think that the window of opportunity had closed. Then came that sublime performance in Abu Dhabi.
By that time the team was clearly losing ground, a situation not helped by its failure to get to grips with its double DRS F-duct style device and its equally controversial Coanda exhaust.
While Raikkonen was one of the true stars of 2012, Grosjean was a major disappointment. Though clearly talented he had gained a reputation as a "nutcase" particularly because of his wild and erratic starts. In Belgium he was responsible for an incident which eliminated Alonso and Hamilton at the first corner, indeed, the Spaniard was lucky not to be seriously injured, or worse. Consequently, the Frenchman became the first driver to be banned from a race (Monza), his place taken by Jerome d'Ambrosio.
On his return the Frenchman was clearly far more subdued and circumspect, the lack of points however saying more about the car than his lack of determination. Claiming that he had learned his lesson, if he has he would be worth watching in 2013, though some insisted he was still too wild and reckless.
With funding, not least from Coca-Cola, things were look good for the Enstone team in 2013, and if Allison and his men were to pick up where they left off, it could be an interesting season for the British team.
With the team taking victory in Melbourne, courtesy of Raikkonen, things got off to the best possible start, though Grosjean, who experienced handling problems, could only manage tenth having qualified eighth. Sadly, in many ways it was the team's highlight of the year.
Though it was on the pace at most circuits, it was problems behind the scenes, mainly financial, that were to dominate. Not as badly affected by the Pirelli rubber as some, even the change to the compounds at mid-season didn't seem to damage the team as much as its rivals.
First to launch its 2013 contender, the team persisted with its Coanda exhaust and a number of other 'devices', the Enstone outfit maintaining its ancestors' reputation for innovation.
However, early in the season there was talk of Lotus being one of several teams suffering money problems, the flames of speculation subsequently fanned when it was revealed that James Allison - widely regarded as one of the up and coming technical stars - jumped ship… the Englishman returning to Ferrari.
Shortly after Allison's departure - which was with immediate effect - Lotus announced that it had agreed a deal with Infinity Racing Partners Limited (Infinity Racing) which was to acquire a 35% minority stake in the team. Sadly, by season end the deal had not yet been finalised. Indeed, as Infinity morphed in to Quantum Motorsport, the reasons for the failure to conclude the deal became ever sillier.
In the meantime, as more top members of staff sought positions elsewhere, it was revealed that Raikkonen had not been paid. While Eric Boullier did his best to paper over the cracks and hold things together it was clear that the team was in difficulty.
Grosjean went from strength to strength, the Frenchman clearly benefitting from his time with a sport psychologist, the erratic antics of 2012 now a distant memory. However, after several 'warnings', Raikkonen eventually gave up and walked out on the team with two races remaining having revealed that he hadn't been paid a single euro for his year's work.
Despite its obvious problems, finishing fourth in the championship, 39 points shy of Ferrari and 45 shy of Mercedes, was no mean feat and Boullier and his men deserved to be applauded... under the circumstances.
Raikkonen gave 100% while Grosjean was one of the true revelations, the Frenchman finally living up to that early promise. Indeed, in the latter stages of the championship he was the only driver giving Vettel a run for his money.
Going into 2014 the financial situation was still far from settled, though Boullier gamely insisted that all was well. To that affect, as Raikkonen headed off back to Maranello, Pastor Maldonado was welcomed along with his PDVSA money and Grosjean promoted to the role of team leader.
The alarm bells first rang when Technical Director Nick Chester confirmed that the team would not be attending the opening test in Jerez. "We're going to keep our car under wraps a little longer than some other teams," he admitted. "We've decided that attending the Jerez test isn't ideal for our build and development programme. We are likely to unveil the car before attending the Bahrain tests, and in Bahrain we should really be able to put the car through its paces in representative conditions."
Of course, part of the problem was revealed at Jerez when the other Renault powered teams were barely able to put more than a few laps together. Over the course of the four days, Renault-powered team managed 151 laps compared to 445 (Ferrari) and 875 (Mercedes).
"A number of related things have been troublesome," admitted Renault's Managing Director (Technical) Rob White, "principally concerning the control and operation of the various sub-systems of the Power Unit within the car. For example on the first run day, we had problems with a sub-system within the Energy Store that did not directly concern either the battery nor the operation of the battery - it is an electronic part that was in the same housing as the Energy Store. We subsequently had problems with turbocharger and boost control systems with knock-on effects on the associated engine management systems, subsequently provoking mechanical failures."
As its rivals prepared to head to Bahrain, Lotus went to Jerez for two days of 'filming'. Not for the first time, its approach to regulation changes was somewhat unique - Benetton and all that followed are in its DNA - and consequently nobody was too surprised by its 'twin nose' approach.
Once testing proper got underway, it was clear that in addition to its burdensome power unit, Lotus was running a dog of a car. Meanwhile, after days of speculation, it was revealed that Eric Boullier had left the team, the Frenchman subsequently popping up at McLaren as Racing Director.
Along with his role as co-Chairman, Gerard Lopez took over as Team Principal, the Genii Capital boss now fully immersed in the team he was funding.
Despite its radical look, the E22 was awful and, in tandem with its Renault power unit, it was clear the team would struggle. That said, it was never clear how much the team would struggle, scoring just 10 points over the course of the year and slipping to 8th in the standings.
Indeed, the team's season was summed up best in Abu Dhabi when Maldonado's car stopped after 26 laps and burst into flames. Back in the pits the mechanics were seen laughing, clearly delighted to see the back of the car and the year.
In reality there is little to dwell on, the team's decline was dramatic. Grosjean was unable to build on the obvious progress made in 2013 whilst Maldonado continued to do what he does best - bring money from PDVSA and cause incidents.
Away from the track despite the insistence of some sections of the media, Mansoor Ijaz' money never arrived, indeed he wasn't seen. Consequently, when Marussia and Caterham both went into administration, Lotus was one of the first teams to call for some spending sanity within the sport.
With both drivers retained for 2015 - Maldonado courtesy of his oil millions and Grosjean because there were no other suitable offers - the Enstone outfit has made the decision to switch to Mercedes power units, possibly in a 'if you can't beat 'em..." move.
Like the song said; "things can only get better", but didn't that 'anthem also end in failure?
