So we reached out to its PR team. And interviewed the company's CEO, Daniel Barel. He told us everything was in-wheel, which seemed incompatible with the reduced unsprung mass the company claimed to have achieved. Nothing a visit to the Frankfurt Motor Show could not clarify, especially with the help of Ran Dekel, the automotive team leader for the company.
Dekel gave us an extensive explanation of what the REE system offers. And not all is inside the wheel, as Barel had previously told us. The impression we had was that he just could not clarify all our doubts. Was it a problem with patents? According to Barel, no. Apparently, it was a request from Musashi, its main partner.
"It has a torque transfer module between the motor and the wheel. The suspension has a 150 mm travel for 17-inch wheels and steering is by wire," said Dekel. "A larger wheel will be able to provide more travel."
