The Spanish circuit was the scene of a famous triumph last year, with the Münnich Motorsport teams and the drivers judging the greasy conditions to perfection as Esteban Guerrieri won from 16th on the grid, heading a 1-2 from Nestor Girolami.
In normal conditions, the races were trickier for the Honda Civic Type R TCR quartet and all four are expecting their toughest weekend of the season yet at Aragon.
An increase in Balance of Performance weight from 10kg to 20kg, coupled with a 60kg hike in compensation weight, means the cars will run 70kg heavier in Spain than they did at the opening two rounds.
All four drivers are nevertheless ready for the challenge, knowing it is important for their early title aspirations that they maximise their points haul where possible this weekend.
With two victories from the opening four races of the season, ALL-INKL.DE Münnich Motorsport currently lead the Teams’ Championship; it is the first time they have done so.
Leading the charge is Attila Tassi, who sits second in the Drivers' Championship and just five points shy of the summit following a breakthrough first victory at Estoril.
Attila took a hat-trick of top-10 finishes on the WTCR’s second visit to Aragon at the end of the 2020 season, with a best finish of eighth.
His team-mate Tiago Monteiro is eager to respond following the disappointment of losing a home victory last time out at Estoril, having led the majority of the race that Attila won before his bonnet came loose.
Despite a non-score as a result of that issue - without which he would have led the standings by 20 points - Tiago remains in the top five overall and is enjoying his best start to a World Touring Car season since his return from injury.
Though factors have conspired against him on both racedays so far this season, Esteban is level on points with Tiago in a share of fifth in the standings, in part thanks to an excellent record in qualifying; the Argentinian has taken 16 of the maximum 20 points on offer from the first two rounds.
That total has also been scored by his ALL-INKL.COM Münnich Motorsport stablemate Nestor. ‘Bebu’ was the best Honda qualifier on both of last year's visits to Aragon, and is hoping to bounce back in Spain after a difficult raceday in Portugal.
