The most advance auto transmission instead of CVT, the world’s 1st 9 speed created by ZF offers smoother gear change and optimize fuel efficiency. We can see most cars in production now shifting to auto 6 speed from 4 speed now and soon, the 9 speed will also be widely used by most cars. Read full news from thestar below.
WORLD’S 1ST 9 SPEED AUTO TRANSMISSION GEARBOX BY ZF
DUSSELDORF: A nine-speed automatic gearbox is coming and it can be adapted for use in hybrids and all-wheel drive cars as well as in stop-start applications.
ZF Friedrichshafen AG presented the world’s first nine-speeder at the International VDI Conference “Transmissions in Vehicles 2011″ earlier this week at the German town of Friedrichshafen, 587km south-east of here.
With its two model ranges, the ZF transmission covers a torque range between 280Nm and 480Nm.
Thanks to its construction kit principle, the basic 9HP transmission can be supplemented in line with special requirements.
The gearbox is more fuel efficient than a six-speed automatic transmission, offering savings of up to 16% in front-transverse installations.
The new transmission owes this fuel efficiency to its high total spread of 9.84.
Very small gear steps can also be realised, resulting in better driving comfort and ensuring the engine always runs in the consumption-optimal speed range.
In the ninth speed, there are only 1,900rpm at 120kph instead of 2,600rpm in case of transmissions featuring six speeds.
Development of the world’s first 9-speed automatic passenger car transmissionSignificant improvements in fuel economy expected
Under high pressure – ZF is working on the development of new fuel-efficient transmission generations. The latest innovation: an entirely new automatic passenger car transmission, developed with 9 gears for vehicles with a transverse engine.
Already at the IAA 2009 (International Motor Show) in Frankfurt, Germany, ZF presented a concept study for front-transverse transmissions which has entered serial development now. Approximately 80 percent of all passenger cars worldwide feature a transverse engine installation. ZF is developing a state-of-the-art automatic transmission for this type of engine installation, which will significantly improve fuel economy. All around the world, new customer segments will be conquered with this transmission. Transmission production has been scheduled for Greenville, SC, USA.
Fuel economy and increased performance
With its 9-speed automatic transmission for vehicles with transverse installed engines, ZF will once again establish a benchmark in terms of fuel consumption. Compared to today’s standard 6-speed automatic transmissions for front-transverse design, ZF’s new 9-speed automatic transmission clearly improves both driving performance and fuel economy. The modern shock absorber systems in the torque converter, which make a rapid lock-up of the converter clutch possible, also mean better fuel economy and lower CO?emissions.
Just like the 8-speed automatic transmission for longitudinal installation, the new 9-speed front-transverse transmission ensures that the extremely short response and shifting times are clearly below the threshold of perception. This means that double shifts and direct multiple gearshifts are also made possible. Thus, the new transmission system is equipped with the same ‘sporty genes’ as already its 8-speed automatic transmission predecessors; in conjunction with the excellent shift comfort characteristics, they certainly entail ultimate customer satisfaction.
wow
main highway malaysia xsompat nk raso 9speed, da kono slow blik..
rasanye x sempat pakai kot gear terakhir,
9 speed ni tak bermakna ambil masa yg lama untuk tukar,Mcm ZF6 Speed auto yg ade kat public bus negara lain,Baru jalan jer dah tukar gear 2 pergi gear tiga tak sampai 30m dan seterusnya.Minyak save tapi clutch gear plak tak boleh pakai cikai nyer.Ade pro n cons.Mcm moto cagiva mito 125 thn 91 7 speed.gear 6-7 tak banyak beza.Yg best ialah auto 5-6 gear jer.7 speed tu semua tambahan jer.
Is it a good thing?
kalo 9 speed auto untuk kereta berhorsepower rendah xde bezanya…….paling best kalo diguna pakai untuk kereta berhorsepower 280 ke atas……..itupun kalo nak rase effect dia kat highway ajela jalan kt bandar jgn harapler…….gear baru masuk 5 dah sampai traffic light dah……
Aku dah bwk Rolls Royce Ghost yg pakai ZF 6 speed masa kwn sewa untuk hari perkahwinan dia,Gear 1-2 mmg dekat,Gear 6 selalu bila rpm dekat 4,500..Mmg mantop tekan2 alih2 dah sampai 140kmh mcm tak rasa gitu
To Norman,
Cayala bro…..eeer Rolls Royce Ghost tu member ko sewa berape riban utk upacara raja sehari tu bro….peeergh..masyuuk..ha lagi satu alang2 aku rase ko memang tau pasal kete nie,kalo gear 6 dah dekat RPM 4,500 kalo kete2 yang bakal ade 9 gear nie tahap RPM dia max sampai berape agaknya……..
120kph rpm baru 1900 je?? msti semuuuuttt je kn..saga blm aku 120kph rpm dh cecah 4k..meraung je enjin 2..huh..apepun x bole!! hahha =p
