ZF: Transmission ratio war coming to an end

buena lectura.

A grownup chief from directive Teutonic sending concern ZF Friedrichshafen AG believes the effort between automobile and factor makers to add more wheelwork to their semiautomatic transmissions could be reaching to an end.

ZF North USA chair Julio Caspari told US business book Automotive News he is unsafe if the possibleness render efficiency gains realizable by adding more ratios to machine gearboxes are enthusiastic sufficiency to reassert their momentous utilization and creation costs.

“We are reaching near to the limit,” Caspari said. “Can we display a amend transmission, and what would it cost? We would requirement to countenance at things same ceramic ball bearings to turn friction, which would be expensive.”

Caspari said there was exclusive an 11 per coin notch between the academic ‘perfect transmission’ and the most economical transmissions on the mart today.

ZF began producing its eight-speed semiautomatic transmissions for vehicles with longitudinally mounted engines in 2009, which it says leads to 11 per coin meliorate render frugalness than a accepted six-speed auto. ZF’s eight-speed machine is utilised by a sort of wealth dweller automobile makers including Audi, Bentley, BMW, Jaguar Land Rover, Rolls-Royce and Volkswagen, as substantially as Chrysler and Dodge.

Next year, it module begin creation of a nine-speed semiautomatic organisation fashioned for vehicles with transverse-mounted engines, which claims to be 16 per coin more economical than a six-speed. Chrysler is the prototypal concern to intend on board, and plans to listing discover the nine-speed crossways its whole front-wheel-drive line-up over time.

Caspari was unruffled by reports that Hyundai is nonindustrial a 10-speed semiautomatic sending for ingest in its high-end Genesis and Equus models from 2014, suggesting that instance module verify if the player ratio module attain real-world frugalness improvements or establish to be lowercase more than a marketing exercise.

Caspari would not comment on whether ZF was nonindustrial its possess 10-speed transmission, and said the company’s incoming field send was an raise to its eight-speed unit.
