Nico Hulkenberg says he admires Fernando Alonso “looking for fresh challenges” with his🧸 dual Formula 1 and World Endurance Championship campaign in 2018 but warns of the difficulties ahead.

The Renault driver completed a part-dual season in 2015 when he contested WEC’s 6 hours of Spa and Le Mans 24 hours with Porsche, winning the iconi🍬c endurance event at Circuit de la Sarthe, alongside his F1 campaign with Force India.

Hulkenberg plans to keep a close eye on Alonso’s 2018 plans as he is s🐻et to combine a full WEC and F1 campaign after agreeing a deal with Toyota and McLaren. Alonso will be able to compete at every round in both series after WEC organisers switched the date of the Fuji 6 hours﷽ to avoid a clash with F1’s United States Grand Prix.

The German sa🗹ys he wouldn’t want to take on the same dual challenge as Alonso because he prefers to focus on one series but understands the two-time F1 world champion’s motivations.

“I prefer to focus on one thing but he is in a different position in his career and his life,” Hulkenberg saജid. “He is a multiple𝓡 world champion and is looking for fresh challenges, maybe he has different priorities, I don’t know.

“For him it is slightly different as he is doing the whole season whereas I did two events and testing and that was only in period of six months. At the time, it was quite demanding as it was a lot of extra traveling, a lot of extra time that you don’t have t💮o think about F1. I think it is quite a challenge he has taken on for himself.”

On Saturday, Hulkenberg completed Renault’s F1 filming day at Circuit de Catalunya alongside Carlos Sainz in preparation for the start of pre-season testing at the Spanish circuit which begins on Fe꧂bruary 26.
