Australia’s most affordable hybrid 1 HONDA JAZZ HYBRID – Low Emissions and Practicality without Compromise The all-new Jazz Hybrid is another The IMA system is shared with all example of Honda’s commitment to Honda’s hybrids, taking advantage of producing fuel efficient engines that are the proven reliability of this important also fun and practical. The Jazz Hybrid is technology. With almost two decades of Australia’s most affordable hybrid and development and 10 years of sales, the joins Honda’s other hybrid models – Honda IMA system has proven itself to Civic Hybrid, Insight and CR-Z. be a flexible and dependable system, with over one million hybrid vehicles The Jazz Hybrid does not lose any of the sold around the world. practicality of the petrol-powered Jazz, with the compact nature of Honda’s The all-new Jazz Hybrid uses the same IMA system allowing this light car to 1.3 litre i-VTEC engine and electric retain its ultra-flexible ‘Magic Seats’ motor as the Insight. The system is and 223 litres of boot space (with the combined with a CVT gearbox and rear seats in their normal position). has an emission count of just 107 g/ With the rear seats down, the cargo km of CO2. Fuel consumption is just 4.5 area (load to window) is 722 litres. l/100km combined urban/extra urban. The IMA battery pack and power control unit have been integrated in the area under the boot floor, retaining the normal boot area and allowing the ‘Magic Seats’ to fold in a similar manner as the petrol version (Utility mode is slightly different). This means that the seats fold flat, to provide a surprising 722 litres measured to the window and accommodating tall items within the car. 2 HONDA JAZZ HYBRID – Low Emissions and Practicality without Compromise Visually, the Jazz Hybrid is distinguished The Jazz Hybrid is available with from the rest of the Jazz range with the following specifications: headlights that have a chrome-blue • 1.3 Litre SOHC i-VTEC engine surround, clear rear LED tail lights, delivering 65kW @ 5800 rpm and chrome-blue front grille and a chrome 121Nm of torque at 4500 rpm tailgate garnish.

This virtually eliminates the which consists of a low-friction 1.3 litre pumping losses, decreasing resistance engine that serves as the primary power to allow the IMA motor/generator to source assisted by an ultra-thin electric operate more efficiently and increase motor, coupled with a Continuously energy recovery to charge the battery. Variable Transmission. The sealing of the cylinders means the air trapped within it can be used like a Honda was the first to introduce hybrid spring, increasing the efficiency without motoring in Australia in 2001 and also the necessity to decouple the engine. introduced the world’s first six-speed manual transmission with a hybrid The technology used to shut drivetrain in 2011. IMA technology has the cylinders, Variable Cylinder featured in the Insight, Civic Hybrid and Management (VCM), is also used to the CR-Z. Over this time, the system has shut all four cylinders when only little evolved and become more compact and torque is required – during low speed lightweight, ensuring that one of the most cruising for example. In this mode the famous attributes of the Jazz – practicality – Jazz Hybrid is powered by the electric is not diminished. motor only, with the pistons running idle, meaning no fuel is used and The 1.3 litre i-VTEC engine has been zero CO2 is produced. The Jazz further enhanced to improve fuel economy. Hybrid can stay in this electric mode The low-friction, pattern coated piston fractionally longer by virtue of its design has been combined with an lower weight and shorter cabling ultra-efficient catalyst to optimise this route between the battery and motor. highly efficient power unit. 5 ENGINE AND IMA SYSTEM Drivers can see when the car has The motor uses coils with high-density entered the EV mode through the windings and high-performance Multi-Information Display (MID) where magnets to produce 10kW and 78 Nm. a graphic indicates if the car is being As with other Honda hybrids, the motor powered by the engine, electric motor or is constructed using flat wire windings, the two combined. which have an oval cross section. The use of flat wire reduces the thickness In addition, virtually everything possible of the winding, without reducing has been done to the engine to reduce its density, which makes the motor friction, including an offset crankshaft/ compact enough to slot into an connecting rod design, plateau honing of existing model such as the Jazz. the cylinders for a smoother surface and a second low friction piston ring. The engine and IMA system produces 72kW at 5800rpm and 167Nm at 1000- 1700 rpm. The key to Honda’s hybrid systems is the support given by the electric motor that can help boost performance as well as keep emissions and fuel consumption to a minimum. 6 ECO ASSIST A few years ago, while monitoring When the ECON switch is depressed, customer use of the Jazz, the development the Jazz Hybrid enters ECON mode, team found that there were significant resulting in the following: differences in the fuel economy achieved • Power output is limited and torque is reduced from one driver to another. For example, by four percent (except when the driver presses at an average speed of 30km/h, there the pedal to the floor e.g. when overtaking) were differences of up to 21 percent in the actual fuel consumption being • Smoothes driver accelerator input to optimise recorded by different drivers. throttle position and engine speed. At any engine speed, there is an optimum throttle With this in mind, the engineers tweaked angle, which if maintained, results in the best the car’s management system in an fuel efficiency. Some drivers apply a more on/ attempt to minimise the effect of varying off approach to throttle control, often pressing driving styles on fuel economy. the accelerator down too far. To counteract When the tests were repeated, the least this, the system ‘smoothes out’ driver input efficient drivers improved their results by maintaining the throttle opening to match and the difference between all the the speed and conditions.
