re: Maruti Ciaz SHVS with Integrated Starter Generator & idling start / stop system. EDIT: Now Launched! First, one has to appreciate Maruti Suzuki for "democratising" different technologies by introducing them in their mass-market cars, like AMTs and now this SVHS. ![Thumbs Up](https://www.team-bhp.com/forum/images/smilies/thumbs up.png) It doesn't have to be complicated, cutting edge stuff like full hybrids which would increase the cost tremendously and hence be unsuitable in sub-1 million rupee cars. Second, I think this is certainly NOT going to be a misleading piece of marketing like what one company did with their "micro-hybrid" label, which turned out to be nothing more than mere start-stop technology. Third, I guess this is going to be somewhat similar to Nissan's S-Hybrid system that is used on their Serena (and possibly some other products). Let's take a look at how Nissan's S-Hybrid system functions: Quote:
The S-HYBRID (which stands for "smart" and "simple" hybrid) powertrain equipped in the Serena is a simple and compact hybrid system. It mounts an upgraded version of the ECO motor used in the existing Serena, and serves as an auxiliary motor to increase power output and power generation capabilities. The hybrid system also adds a sub battery for increased storage capacity, which fits in the current engine compartment. Mounting the entire hybrid system inside the existing engine space maintains the key features of the Serena, such as largest-in-class cabin and flexible seat configurations.

The Serena S-Hybrid is powered by a MR20DD 2.0 litre engine with 147 PS and 210 Nm (figures are from engine alone, excluding 54 Nm from electric motor). This direct injection twin-CVTC unit is paired to Nissan’s latest Xtronic CVT gearbox with Adaptive Shift Control.
An Idling Stop System shuts down the engine when idle, and restarts in just 0.3 seconds after the brake is released. There’s a timer that shows the driver how long idle stop is in use.
The S in S-Hybrid stands for “smart” and this Serena is actually a “micro-hybrid” of sorts. What Nissan did was beef up the ECO Motor, the Serena’s starter motor that controls Idling Stop and functions as an alternator during deceleration.
The starter motor uses a belt pulley type cranking system instead of a normal gear type unit. Even the regular Serena has this, but in the Serena S-Hybrid, the capacity of this motor is increased from 1.0kW/150A to 1.8kW/200A, and the engine bay has an extra 12V-27V-Ah battery. The main 12V-64V-Ah battery drives the motor, while the sub battery powers electrical components like the radio, wipers, etc.
With it, the engine also does not need to move the car AND power the car’s electrical needs at the same time, resulting in fuel savings. Fuel economy is listed as best in class – 15.2 km/l in Japan’s JC08 test cycle. However it’s important to note the ECO-motor does actually contribute to acceleration – this is not a motor assist system like Honda’s IMA.
