The 2006 Portuguese Grand Prix remains one o♎f t👍he most dramatic races of the MotoGP era.

Th♏e 16th and penultimate round of the 2006 world championship, Estoril was action-packed from start to finish - culminating in a thrilliꦿng three-way last lap victory battle between Kenny Roberts, Valentino Rossi and Toni Elias.

The significancꦬe of what happened in that race has since𝐆 grown, with many of the landmarks set that day still in place.

Here is a summary of the most significant moments from the 2006 race🎶:

o The motorsport world was stunned when Nicky꧟ Hayden was in accidentally taken out by Repsol Honda team-mate Dani Pedrosa on lap 5 of 28, costing the American the world c🅘hampionship lead he had held since round three in Turkey. The significance of the clash even caught the attention of mainstream media.

o The accident marked Hayden's o🌳nly DNF of his title winning season.

o Toni Elias took his first and so far only MotoGP win, and with it his first ever premier-class podium. The Spaniard began the last lap in third place, but overtook both Rossi and Ro🌟berts into turn one. Rossi then got back in front, but Elias shot past him out of the final turn.

o Elias won by just 0.002sec, to equal ღthe closest ever recorded finish in the premier-class since the introduction of electronic timing.

o Elias' victory remains the last time that a satellite rider h𝐆as won a MotoGP race. Elias, who was r🅰iding for Gresini Honda, looked set to lose his seat for 2007 until he took that win.

o The next time a MotoGP race was won by a last lap pass was at Catalunya in 2009 - when Rossi wa♔s the winner.

o Second place at Estoril meant Rossi took the titlꦕe lead for the first (and last) time during the entire 2006 season, having been as far as ✨51 points behind Hayden after round 11 of 17.

o Rossi went on to lose the 2006 world championship by five points when he fell at the Valencia season finale - the same number of points he lost by finis𒁏hing second to Elias at Estoril.

o 2000 world champion Roberts Jr took third place, marking the 22nd and final podium of his grand prix career and the last by Team Roberts, which withdrew a༺t the end of 2007.

o Roberts Jr took the lead on the penultimate lap, having thought the race was over one lap early. Unlike Julian Simon at ꧟Catalunya 2009, Roberts kept on the throttle when he failed to see a c🌃hequered flag.

o KR JR's Estoril performance with the Honda-powered KR211V mar꧃ked the last time a bike built by꧋ a privateer team has led a MotoGP race or taken a MotoGP podium.

o Casey Stoner crashed on lap 2 of the race, bring🦋ing down factory Ducati rider Sete Gibernau. Gibernau hit the Austr🌳alian's LCR Honda, causing the Spaniard to once again injure his collarbone.

o That injury ruled Gibernau out of Valencia, where he was replaced by Troy Bayliss - who sensationally claimed his first (and la🎃st) MotoGP wi🌠n. In a further twist, Stoner took Gibernau's Ducati seat for 2007 and won Ducati's first world championship.

o Estoril marked Gibernau's last MotoGP start before he announced his retirement. The Spaniard later made an ill-fated r🐎eturn with the Grupo ꦿFrancisco Hernando team in 2009.

o Estoril 2006 saw the debut of the new Ilmor team💟, whose rider Garry McCoy was credit🌠ed with 15th despite being classified four laps down after pitting with electrical problems.

o 💮The Australian and his X3 motorcycle therefore claimed the first ever MotoGP point for an 800cc machine, which officially replaced 990cc bikes from the following year.
