Jaguar’s engineering team has decided to specify BorgWarner’s pre-emptive on-demand transfer case across more vehicles in the model range. Initially available for the XF sedan, BorgWarner will also provide the all-wheel drive (AWD) technology for the XE sedan and F-Pace crossover.
The transfer case directly connects to the vehicle’s control systems, which monitor signals such as steering wheel angle, accelerator pedal position and wheel speed. To optimize AWD function, pressure from the lightweight centrifugal electro-hydraulic actuator (CEH) compresses the clutch pack to distribute torque between the front and rear axle, as needed. The AWD transfer case is claimed to offer pre-emptive linear clutch actuation, enhanced vehicle traction and stability control. The case is also equipped with BorgWarner’s HY-VO transfer case chain, a pumpless design and sump management. According to BorgWarner, the compact chain and gear drive options reduce total vehicle weight and facilitate optimum packaging.
BorgWarner produces the AWD transfer case for the Jaguar XF at its newly built facility in Oroszlány, Hungary. Jaguar Land Rover is the first European automaker to feature the system.
“We are pleased to expand our long-standing cooperation with Jaguar Land Rover by providing several vehicle models with our innovative pre-emptive on-demand transfer case,” said Dr Stefan Demmerle, president and general manager, BorgWarner PowerDrive Systems. “Our state-of-the-art AWD solution helps customers achieve their ambitious efficiency and weight targets, and enables accelerated development cycles. Additionally, the transfer case offers superior dynamic performance and drivability.”
