Outlander sport là hang thấp hơn Tucson phải không?
Kết quả vẫn lập lại
Xe Hàn kỹ thuật thấp hơn và luôn luôn nặng hơn
Vật liệu kém hơn nên xe dễ bị lỗi sau môt thời gian sử dụng ví dụ dễ cháy
Xe Hàn vỏ cứng, dễ gây tử vong hơn.

hơn Tucson phải không?
kết quả vẫn như cũ
vỏ mềm mà an toàn hơn thì bọn tây lông nó crash test làm gì vậy anh ,nói như anh vậy ỉn sao ko đem qua mỹ bán ?

The man who invented the dual-clutch gearbox was a pioneer in automotive engineering. Adolphe Kégresse is best known for developing the half-track, a type of vehicle equipped with endless rubber treads allowing it to drive off-road over various forms of terrain.

Suppliers[edit]
BorgWarner[edit]
BorgWarner Inc. supplies[11] wet dual clutches[2] and electrohydraulic control modules (mechatronics)[1][11] for these dual-clutch transmissions, along with complete dual-clutch transmission and transaxle assemblies. BorgWarner, which call their technology "DualTronic",[1][11][15] entered series production (excludes Bugatti Veyron) for Volkswagen Group,[5][11] which renamed Direct-Shift Gearbox (DSG) in 2003 in the Volkswagen Golf Mk4 R32.[8][9][15] The company signed further agreements with three other (unnamed) European automotive manufacturers to incorporate their components in DCTs.[16]
On 14 January 2009, BorgWarner announced a joint venture with the China Automobile Development United Investment Co., Ltd., which is owned by 12 Chinese automakers. This joint venture is known as the BorgWarner United Transmission Systems Co., Ltd., and is located in Dalian, China. The company has produced various dual-clutch transmission modules beginning in 2011.[17]
The Nissan GT-R uses BorgWarner components, including the dual-clutch module, clutch-control, shift-actuation systems, and synchronizer assemblies.[18]
Eaton[edit]
Eaton Corporation developed the first dual-clutch transmission for class 6-7 trucks in North America - Procision.[19]
Fiat Powertrain Technologies[edit]
Fiat Powertrain Technologies developed a dual-clutch transmission with Magneti Marelli and BorgWarner called Euro Twin Clutch Transmission. Magneti Marelli produces the control system, which integrates BorgWarner's hydraulic actuation module into its own power and transmission control units.[20] It can handle torque inputs of up to 350 N⋅m (260 lb⋅ft), making it the highest-torque dry-clutch application.[21] Its weight of 81 kg (179 lb), including oil and transmission control unit, its three-shaft architecture, especially axially, means it can be installed in several types of B- and C-segment vehicles.[22]
FEV GmbH[edit]
FEV developed a DCT with an integrated electric motor, providing hybrid capability. The 7H AMT Transmission provides seven forward speeds with multiple usages of gears (the electric drive can use unused gears from the combustion engine path): this aims to substantially reduce the complexity of the unit, as well as the package size and weight. Another spin-off from this design was the FEV xDCT that provides 10 forward speeds, but with the mechanical complexity of a standard six-speed DCT.[23]
Getrag[edit]
Getrag has developed a range of DCT[24] transaxles, including 7DCL750, a seven-speed transaxle for midengine longitudinal applications, capable of taking more than 750 N⋅m (553 lbf⋅ft).[25] Getrag provided its DCT in its first commercial applications, for the Dodge Journey and Volvo S40 and V50, from mid-2008.[26] Getrag has developed the 6DCT250 dry clutch DCT, with a maximum torque of 250 Nm,
for use in front wheel drive transverse applications. With use of electromechanical actuation, rather than electrohydraulic, the 6DCT250 transmission surpasses the conventional manual transmission in fuel consumption and CO2 emission.[27]
In the second quarter of 2008, Getrag had signed an agreement with Chrysler to supply its PowerShift DCTs for use in American markets.[5] However, due to the global economic downturn, this was subsequently cancelled.[5][28][29]
In 2006, Getrag was also working with Bosch to develop a DCT for use in hybrid vehicles.[5][30]
In 2015, Getrag introduced a new seven-speed, wet-clutch DCT, the 7DCT300,[31] with a maximum torque of 300 Nm. The first application was the Renault Espace with a 1.6 L, Turbo GDI engine.
Getrag dual-clutch transmissions are used in the BMW M3,[32] BMW 335is, BMW X1 (F48), BMW Z4 (E89) sDrive35i, Dacia Duster EDC,[33] Ferrari California,[34] Ferrari 458 Italia,[35]LaFerrari, Mercedes-Benz SLS AMG,[36] Mitsubishi Lancer Evolution X, Mitsubishi Lancer Ralliart, Ford Fiesta, Ford Focus, Renault Megane, Renault Scenic, Smart Fortwo, Volvo V40, Volvo V60 Volvo V70 vehicles.[37]
The 2011–2016 Ford Fiesta and the 2012–2016 Focus with the Getrag DCT's are the subjects of a class-action lawsuit and many individual lawsuits.
Graziano[edit]
Italian specialist Oerlikon Graziano was in the process of developing a wet-clutch DCT for original equipment manufacturer fitment into supercars.[38] They planned to have it in production by 2010.[38] Their DCT is aiming to have a torque-handling capacity of 750 N⋅m (553 lbf⋅ft),[38] and they are also aiming to improve shift quality over their current AMTs.[38] As of 2011, they supplied the seven-speed DCT for McLaren's MP4-12C supercar with a shifting time of 50ms.[39]
LuK[edit]
LuK Clutch Systems, LLC. designed and manufacture the dual dry single-plate clutch system for the Volkswagen Group seven-speed DQ200 direct-shift gearbox (DSG) introduced in 2008.[40] This DSG variant is used in smaller cars, with smaller-displacement engines with relatively low torque outputs.[40] LuK are naming their technology "XSG" for their overview of automated shift gearbox systems,[41] and "Parallel Shift Gearbox" for its own proprietary DCT.[42]
Ricardo[edit]
English specialist consulting engineering company Ricardo plc designed and built the Bugatti Veyron's seven-speed dual wet multiplate dual-clutch transmission, specifically to cope with the 1,250 N⋅m (922 lbf⋅ft) of torque generated by W16 engine.[1][2][5][43]
ZF[edit]
ZF Friedrichshafen AG, with Porsche, designed and now build the two different variants[44] of the Porsche Doppelkupplungsgetriebe (PDK) seven-speed '7DT' dual wet multiplate clutch transmission.[44][45][46][47][48]

Hyundai[edit]

The DCT transmissions used in some Hyundai and Kia passenger vehicles are supplied by Hyundai DYMOS. At the 2009 Geneva Motor Show, Hyundai unveiled ix-onic concept car, which was said to feature a six-speed dual-clutch transmission.[78]
