Welcome to section three of our deep dive collection in to the Perodua Ativa (also called the D55L), where the main target this time is within the transmission that will be utilized by the compact B-phase SUV.
The launch gear is employed when placing off from the cease, previously in comparison to the transmission switches to belt drive like a CVT as a substitute. This was designed to supply a extra immediate travel relationship at very low speeds.
It does not simulate any equipment alterations like specific more recent CVTs from Toyota and Nissan. Now this is one thing users must get used to, particularly if they’re coming from a traditional torque converter automatic like Perodua’s possess 4AT.
At bigger speeds like when freeway cruising, the CVT is at its highest achievable ratio, which could continue to result in the engine being at a large rev position that isn’t superior for gasoline financial state.
The CVT gearbox offers a clean and seamless driving knowledge, resulting in much better driving dynamics in major website traffic situations.

Welcome to fifty percent a few of our deep dive sequence in the Perodua Ativa (usually known as the D55L), the put the leading focus this time is to the transmission that might be utilized by the compact B-phase SUV.
Nevertheless, usually there are some downsides, as CVTs commonly knowledge power losses due to friction (on the belt or chain) as as compared with geared transmission.
pada D-CVT bermain di kecepatan tinggi saat pedal gasoline mulai diinjak lebih dalam, rpm naik, dan laju mobil makin kencang dan konstan.
For additional figures, the corporate suggests that the space between the centre of your enter and output pulleys while in the transmission is simply 136 mm, when the distance amongst the centre of your transmission’s input and output points is simply 168 mm, both claimed for being the smallest on the earth. Limits? Like other CVTs and ordinary transmissions, the D-CVT is can only handle a specific volume of torque, that's approximately 150 Nm. Daihatsu claims its transmission is optimised to be used in all models from mini (kei cars) to vehicles with motor capacities of around one.5 litres. Because kei cars and trucks are limited to 660 cc by regulation, having a max output of 64 PS (sixty three hp), the D-CVT is in excess of up sila klik link ini on the activity. As for your 1KR-VET in the Ativa, it would make 98 PS (ninety seven hp) and one hundred forty Nm, which can be well within just bounds in the D-CVT, And so the pairing is nicely in the limits. So, the effect on driving knowledge? To summarise, the D-CVT really should present sleek acceleration up to medium speeds, but with far better gas intake in addition to a quieter drive at higher speeds.
Challenging-driven DCT automobiles will require clutch pack servicing previously as compared to placid freeway CVT utilization
Both pulleys have movable and stationary elements. The belt drives these pulleys, and their diameters alter dependant on the sheaves’ motion, supplying infinite equipment ratios. When a single pulley expands, the opposite contracts, making it possible for for easy and seamless adjustments in gear ratios.
To the motive force, and as opposed to traditional CVTs, the D-CVT mimics the much larger unfold of gears comparable to the distinction amongst a six-pace transmission and an eight-velocity unit, but in a far more light-weight and compact package that’s Preferably suited to scaled-down vehicles and mated to smaller engines such as the 1KR-VET turbocharged 3-cylinder motor while in the Perodua Ativa.
For extra figures, the company states which the gap in between the centre of your enter and output pulleys in the transmission is just 136 mm, whereas the gap amongst the centre of the transmission’s enter and output components is simply 168 mm, Every single claimed for being the smallest about the earth.
