Members of Jaguar’s Formula E team have been spotted this weekend at the Berlin race. Okan Tur (pictured), the brains behind the Williams Advanced Engineering battery powering all Formula E cars, and Gary Ekerold, who headed up the WAE Formula E battery programme, are both on-site and in Jaguar jackets. (Read our detailed interview with the pair about the design and development of the battery here.)

Williams is working with Jaguar to develop the marque’s debut Formula E entry, which will hit the grid for season three. The British engineering firm will also provide technical trackside support for Jaguar.

It is the first time that we’ve had it confirmed that Tur and Ekerold are part of the new Jaguar effort. We’re assured the pair have been moved away from the battery project at Williams, with Spark taking a far greater technical support role on site.

We’re also told elsewhere in the paddock that the Jaguar entry has prompted other OEMs who had been in discussions about possible involvement in the sport to suddenly get a lot more serious. We’re expecting at least one more global car maker to reveal an involvement (possibly sponsorship followed by technical input) for season three.
