Meanwhile on the responsiveness aspect, the new Shift Control Strategy featured with SmartStream IVT apparently reproduces the shifting pattern of a conventional automatic, which supposedly better reflecting the driver’s intent and driving conditions and therefore making it feel more responsive than the rubber-band effect normally associated with CVTs.Īll these bold claims from this Smartstream IVT, especially in terms of its efficiency, originates from one main innovation over traditional CVTs, and that would be the use of a chain belt instead of a metallic belt as the main power transfer mechanism within the gearbox.
On the efficiency front, paired with a Smartstream G1.6 MPi four-cylinder in the new Elantra, an 8-speed variant of this novel transmission supposedly improves fuel economy by some 4.2%, and engine power loss by a margin of 5-8%. This is all because of Hyundai’s recent claims that its new SmartStream Intelligent Variable Transmission (IVT) is able to provide maximum efficiency, yet also be able to provide better responsiveness and smoothness compared to traditional CVTs on the market today. It is however the last one on the list that has been generating some considerable headlines as of late. The Korean automotive conglomerate is the only auto group in the world to currently have cars that feature all the four main gearbox types within its lineup: automatic, manual, dual-clutch and continuously variable transmissions (CVT). Here’s a surprising fact for the day, the Hyundai Motor Group is currently the only automaker in the world to comprehensively possess the technology for all transmission types. The clever new Smartstream Intelligent Variable Transmission (IVT) looks to be a giant leap forward over the conventional CVTs.
