A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. [1] This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.
Variomatic is the continuously variable transmission (CVT) of the Dutch car manufacturer DAF, originally developed by Hub van Doorne. [1] It is a stepless, fully- automatic transmission , consisting of a V-shaped drive-belt, and two pulleys , each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle ...
The NuVinci CVT system has a small number of parts. [5] [6] Most CVTs have lower mechanical efficiency than competitive conventional transmissions.Since any CVT may allow a power plant, human or motorized, to operate at (or closer to) its speed of optimal efficiency, output torque or output power, the NuVinci CVT may improve a system's overall efficiency or performance compared to a ...
It remains one of the worst vehicles Consumer Reports has ever tested. [40] The publication noted that the car took 37.5 seconds to go from 0–60 MPH, it was dangerously structurally deficient in a 30MPH crash test with a standard car, and its bumpers were "virtually useless against anything more formidable than a watermelon ", all of which ...
Lineartronic CVT transmission. The fifth generation Legacy/Outback and the Subaru Exiga received a newly revised CVT under the Lineartronic name. It is a metal chain, pulley-based CVT, which is considered the most reliable, due to the simplicity of the pulley system and durability of the metal chain.
General Motors shines, but Lexus is on top.
The Multitronic system uses a link-plate chain drive, [2] an oil-cooled multi-plate clutch [2] (initially of six parts, [2] later of seven to enable it to cope better with the high torque outputs of larger turbodiesel engines), and complex electronics, to overcome the traditional shortcomings of CVTs, [2] and allow a CVT transmission to be ...
They have 79 percent more problems, on average. Plug-in hybrids are even worse.
