[3] Easily the most high profile year of action of his career at that point, Al Harthy adapted quickly to the new discipline and became a regular podium contender in the Pro-Am 1 Class of the prestigious championship.

[4] One of Al Harthy's personal highlights of 2010 was his involvement in the Porsche Carrera Cup France support event to the legendary 24 Hours of Le Mans Race.

On 21 February 2012 at a press conference in Muscat, Oman, Al Harthy announced his continued participation in Porsche Carrera Cup Great Britain for a third successive year.

[6] Al Harthy also made his second career appearance in the Porsche Mobil 1 Supercup in 2012 during the FIA Formula One World Championship British Grand Prix weekend at Silverstone.

In March 2013, Al Harthy and chief sponsor Oman Air announced a move from 'sprint' racing into 'endurance' competition after confirming a deal to graduate into the Avon Tyres British GT Championship with the Motorbase Performance team.

[8] Al Harthy also had the opportunity in 2013 to dovetail his British GT season with a campaign in the pan-European Blancpain Endurance Series, also at the wheel of a Porsche 997 GT3-R but with the Slovakian ARC Bratislava squad in the GTR Class.

Partnering team owner Miro Konopka, and running with headline sponsorship from the National Bank of Oman, Al Harthy achieved one class victory during the five-round season at Silverstone Circuit in June.

At the end of the year, Al Harthy made his maiden appearance in the Gulf 12 Hours at Yas Marina Circuit in Abu Dhabi with the Oman Racing Team.

Celebrating the 10th anniversary of 'Oman Racing' in 2017, Al Harthy continued his increasingly strong partnership with Adam but with the engineering of the Aston Martin transferring to British squad TF Sport, headed by ex-racer Tom Ferrier.

Winning the coveted Pro-Am title with a round to spare, and continuing the squad's 100% podium finishing record for the season, Al Harthy and Adam were again joined by Yoluc for the twice-round-the-clock challenge along with British driver Euan Hankey.
