At the Frankfurt Motor Show Peugeot will showcase its new 308 Hybrid HDi, which emits just 90g/km of CO2 and reduces fuel consumption by 58% in the Urban Drive Cycle compared to a standard 308 HDi.
In its pearlescent white and green color scheme, two colors chosen as symbols of purity and ecology, the 308 Hybrid HDi demonstrator is the eagerly anticipated star of the environmental section of Peugeot's stand at the 2007 Frankfurt Motor Show.
This new 308 Hybrid HDi demonstrator represents another step on the path towards the planned commercialization of the technology in 2010. Further evaluation of the original Peugeot 307 Hybrid HDi demonstrator in 2006 has confirmed the choice of a diesel engine, instead of a petrol engine, as the best option to provide the best reduction in fuel consumption and emissions.

In addition, the engine has been designed to meet the future Euro V directive which comes into force in 2009 and offers the possibility of driving exclusively in electric or "ZEV" (Zero Emission Vehicle) mode for journeys in regulated urban centers.
The excellent aerodynamic performance of the 308 hatchback and the use of Michelin's new Energy Saver tyres, which reduce rolling resistance, help to enhance further its performance.

Compared to the previous 307 Hybrid HDi demonstrator presented in 2006, the focus of the development has now switched to concentrating on the packaging of the hybrid technology into the structure of the new 308, and to ensure its compatibility with the future Euro V emission standards.
To ensure a competitive purchase price, priority has been given to using as many components as possible from current Peugeot vehicles. This has enabled the number of specific parts associated with the hybridization of the 308 to be reduced by around 30% compared to the previous 307 Hybrid HDi demonstrator.
A simple, automatic technology
The vehicle is started by a customary ignition key but, unlike a conventional vehicle, this does not start the diesel engine. Instead by pressing the accelerator pedal with the gearbox in automatic mode, the electric motor powers the vehicle. The diesel engine only operates when required and is controlled by a stop and start system. All the powertrain operating modes are controlled by a Power Train Management Unit (PTMU) according to the driver's requirements.
The driver is informed in real time of the powertrain operating mode by a schematic diagram on the vehicle's color multifunction display. Other information is also available, such as the battery charge status or the power train operation mode.
Well equipped and without compromise
The comprehensively equipped demonstrator has all the standard equipment of a Premium Pack 308 and also includes a panoramic glass roof and the RT4 multi-media system with a retractable color display screen. The level of standard equipment, interior space, interior brightness, dynamic qualities and drivability are no different to those of the standard 308.
General dynamic performance is also comparable to a standard 308 HDi. In-gear acceleration, however, both in town and on the open road, is improved with the Hybrid HDi. Indeed, during in-gear acceleration, the diesel engine is backed up by the electric motor which is able on demand to deliver a power boost of up to 31 bhp (and 96 lb ft of torque).
Optimized Hybrid HDi technology
The parallel hybrid power train consists of a 1.6 litre HDi DPFS 110 bhp diesel engine and an electric motor with a continuous output of 22 bhp and a torque of 59 lb ft. The Power Train Management Unit (PTMU) selects the right distribution of power from both units to meet the requirements of the driver and minimize fuel consumption.
The electric motor alone is responsible for starting and driving at low speed, while only the diesel engine is used on open roads and motorways, with both units coming into play simultaneously to provide quicker acceleration. The system is fitted with a 6-speed electronically controlled manual gearbox able to operate in automatic or manual sequential mode.
To extend the battery range, kinetic energy recovered during phases of deceleration and braking is used to recharge the batteries. A special button provides access to an all-electric "ZEV" Zero Emission Vehicle mode. Operation of the diesel engine is then restricted to more pronounced acceleration phases or high speed driving. This "ZEV" mode provides total absence of exhaust emissions and noise pollution.
Technical description of main specific components
The electric motor is of the synchronous type with permanent magnets, developing a continuous power of 22 bhp and a torque of 59 lb ft. However, intermittently its output can attain 31 bhp and 96 lb ft.
An inverter regulates the 150 to 260 volt current from the high voltage battery pack supplying the electric motor in accordance with the torque requirements determined by the Power Train Management Unit (PTMU).
A new generation battery pack has been developed which delivers an output of 200 volts. It is housed in the spare wheel well and does not, therefore, reduce the available boot volume. The batteries are of the Nickel Metal Hydride (Ni-MH) type.
A converter converts the 200 V from the battery pack into 12 V to supply the vehicle equipment in phases of solely electrical operation.
Managed braking maximizes the recharging of the batteries during phases of deceleration and braking. An Intelligent control of the braking optimizes the distribution between regenerative electric braking and traditional dissipative hydraulic braking. The braking management system gives priority to braking efficiency over the recovery of energy.
In order to get every last bit of performance and horsepower from your vehicle, you'll require investing in some modifications. As modifications like wing spoilers, body kits, aftermarket breaks, and performance wheels all of these gives performance benefits to your car; merely setting up your car engine to the fullest will assist you to produce the horsepower required to increase your car over the rivalry down the strip or the street. The following are several well-known ways in how to modify the engine of your car and obtain the performance that you want badly:
• High Performance Radiators - An engine with high performance gives added power, and, as a result, added warmth. This radiator will be required to maintain its coolness. These radiators are made to manage a lot of pressure ranges and higher temperatures compared to OEM radiators. These will assist in keeping your engine performance protected from running smoothly and overheating regardless of anywhere you run your vehicle.
• Cold Air Intake - This can increase and boost the performance of your car engine by a considerable amount. OEM intakes pull in warm air from just about the engine bay, which reduces the capabilities of the performance of your car engine. By supplying a cold stable stream of thick air, the intake of cold air can provide you improved ignition, which provides additional power per stroke, zooming you down the street with superior pleasure.
Turbos and Superchargers -These could boost the performance of your car's engine to a deliberately superior level. Each method provides unlike benefits, and so it will require choosing the one that is right for your requirements. For example, a supercharger provides enhancements in the performance across a broad array of the power band. A turbo, alternatively, offers a performance greater at superior ranges on the RPM (on the whole, a supercharger is immense for the street, while a turbocharger is perfect for the track).

• Custom Ignition System - This can work wonders for your engine. High-tension wires and spark plugs performance could put in horsepower into your engine. Additionally, timing that is advanced could also give you a push that is greater. Performance wires and plugs give more sparks; this is what drives the pistons and ignites the fuel inside your engine. When put together with the intake of cold air benefits, this system of custom ignition will provide you enormous boost in performance.
These are only a small number of car engine modifications that you'll be capable of doing consecutively to make the most of performance and power. Having the exact tools and a bit of assistance, you can increase the performance of your engine to unbelievable heights.
Mike has been working on cars and trucks since he got his first Olds 442 in the early 70's. Since then he was worked on many vehicles and is deeply interested in electronics and the new computer controls of todays vehicles. While it might seem they are limiting the DIY'r he thinks just the opposite. With the right OBDII Code Reader and Haynes repair Manual you can do far more than the days of screwdrivers and timing lights. |
