How the 2008 Honda Civic Hybrid Sedan Works

This is Honda's hybrid answer. The Honda Civic hybrid showcases Honda's renewed commitment to Hybrid technology and gives drivers a environmentally friendly car without any compromise on style, performance or comfort.

Honda's Hybrid system is called Integrated Motor Assist (IMA). Developed in 1999 it was first launched in the 2 seat-er Honda Insight which gave an idea of how advanced it was - 83 miles per gallon on a combined cycle.

Hybrid is the combination of a gas engine with an electric motor. The electric motor is coupled to a powerful battery. The electric motor helps the engine by giving it a boost during acceleration and solely runs the car at idle to reduce emissions and fuel consumption. The battery that powers the electric motor charges itself up with regenerative energy from deceleration and braking. A regenerative brake is a mechanism that reduces vehicle speed by converting some of its kinetic energy into electrical energy. A brake pedal sensor sends a signal to the car's computer, activating systems whenever the driver applies the brake. This allows braking energy from the wheels to be stored as electrical energy in the high voltage battery for future use. Therefore the car never needs to be recharged from an external power supply. This regenerative brake assistance also extends the life of the brakes and their components as it reduces its workload appreciably.

The majority of the hybrid cars available in the market today aren't that good looking. And nobody wants to drive around in a car that looks like a deflated football. Honda engineers have taken note and engineered the components to enhance looks and more importantly, help achieve their primary targets.

The elegant styling combines a sweeping roof-line, a sharply raked windscreen and short overhangs that contribute to the vehicle's advanced mono-form profile. Superior aerodynamics is achieved by ultra-tight body panels that fit firmly around the monocoque frame. A chin spoiler and a lip spoiler are also designated to aid the aerodynamics by reducing turbulence beneath and behind the car. The low-drag alloy wheels are made specifically for the Civic Hybrid so to enhance the looks and reduce excess weight while the opposable windscreen wipers serve both styling and efficient cleaning purposes.

The fuel tank is made from an innovative six-layer polyethylene composite material that blocks fuel evaporation and saves weight. The front sub-frame which accommodates the engine and transmission is produced from hydro-formed elements for increased strength and rigidity. Special rubber floating mounts minimize the level of road and engine NVH (Noise, Vibration, Harshness) entering the passenger cabin.

But it's not all about the looks. Honda's new IMA system gives out more power than a conventional 1.6-litre engine (115PS), but only uses the same amount of fuel as a 1.1-litre car. There's no ambiguous starting procedure or complicated operating system – it looks and drives like a modern, stylish saloon with a top speed of 115mph. The Civic Hybrid's engine took top honors for three successive years at International Engine of the Year "1 litre to 1.4 litre" size category award from 2002 through 2004 and the "Best Fuel Economy" category for 2003 and 2004.

The Civic hybrid is one of the safest cars in its class. It is equipped with ABS and Electronic Brake force Distribution (EBD) to achieve decent stability and high braking performance. Vehicle Stability Assist (VSA) assists the driver in maintaining maximum possible control during cornering, acceleration and sudden manoeuvres by applying braking either to the right or left wheels accordingly while controlling the throttle and brake systems simultaneously.

The Civic Hybrid uses multiple "load paths" to limit penetration of the car's structure by absorbing more of the crash energy if it encounters a collision. Whatever energy gets through is mitigated by the car's eight standard air bags. The Civic Hybrid has earned top safety rankings from NHTSA and IIHS. To help reduce pedestrian injuries in the event of a collision, the Civic Hybrid's bonnet and wing areas are designed to deform if contacted by the head of an adult or child pedestrian. Energy-absorbing collapsible bonnet supports, wiper arms and wing mounts are designed to allow a degree of deformation in an impact making this car very safe to travel in.
