The participation of Israelis in the rally's lightweight vehicle and truck categories comes after a rapprochement between Israel and Arab states that has been in high gear, fueled by Riyadh's quiet assent.
In total, ten drivers, navigators and support staff entered Saudi Arabia on Israeli passports, according to team member Omer Pearl.
"It was extraordinary - huge dunes that go on for hundreds of kilometers," said Danny Pearl, one of the Israeli drivers and Omer's father.
For decades, Saudi Arabia, Islam’s birthplace and supporter of the Palestinian cause, shunned official contacts with Israel, with virulent anti-Jewish rhetoric the norm among clerics.
But Riyadh gave its assent to Israel's US-brokered normalization of relations last year with the United Arab Emirates and Bahrain, although it held off on establishing full ties itself. Israeli airliners have since been permitted to cross Saudi airspace, trimming flight times.
"I couldn't take my eyes off the track to enjoy the sights, but I kept thinking: This is our neighbor. Maybe one day - tomorrow, the day after - I'll be able just to drive in for a trip," Pearl senior said.
However, the rally website listed the teams as Belgian and American - a possible indicator of official reluctance to publicize an Israeli presence.
The Saudi government's media office and rally spokespeople did not immediately respond to requests for comment.
The annual rally started in 1978 as a race from Paris to the Senegalese capital, Dakar, but moved from Africa for safety reasons in 2009. The race is now held entirely in Saudi Arabia, after a stint in South America, where some countries withdrew from hosting parts of the route due to concerns over its environmental impact.
The race began in Jeddah, its circuitous route passing by Riyadh, Ha'il and the new mega-business zone called Neom under construction at the northern tip of the Red Sea.
