Abstract
With over 72% of registered vehicles in India being 2 wheelers, the environmental impact of this transportation segment is significant due to the sheer number of vehicles plying on the roads coupled with the congested urban environment prevalent.
‘DVI’ (द्वि), Sanskrit for 2, is a fully integrated mild hybrid powertrain in a compact vehicle that efficiently utilizes space and P1 parallel coupling to provide a spirited driving experience, while still being as effective, if not more in bustling urban roads.
All functions listed are inherently possible thanks to its small, compact, integrated drive configuration. Additionally, the driver’s interaction with the vehicle doesn’t feel as alienating or complicated due to the seamless integration of the control strategies of both systems, giving the driver uncompromising performance and efficiency. To an average driver, it feels but like a higher capacity vehicle without the disadvantages that come with a larger, less efficient & heavier engine.
