2005 Honda Accord Hybrid Sedan Overview Introduction Since the Accord’s launch as a compact hatchback car in 1976, it has earned widespread acclaim as a leader in smart design, superb quality and world-class efficiency. In its 28-year history, the Accord has constantly re-invented itself, going from that original compact hatchback to today’s premium intermediate sedan and coupe. The seventh-generation Accord V-6, released in 2003, once again raised the bar for performance, safety and value in the intermediate segment with a highly efficient and powerful 3.0-litre, 240-horsepower, SOHC VTEC V-6 engine, 4-wheel disc brakes and a standard anti-lock braking system (ABS) on all models, along with standard features such as air conditioning, an AM/FM/CD stereo system, power windows and door locks. In 2005, the Accord further establishes its role as a technology, performance and efficiency leader with the introduction of the Accord Hybrid, the world’s first V-6-powered gasoline- electric-hybrid vehicle. Boasting the highest fuel efficiency for a V-6-powered automobile, Accord Hybrid utilizes the third-generation of Honda’s exclusive Integrated Motor Assist (IMA) hybrid system featuring new Variable Cylinder Management (VCM) technology. By combining a high-output V-6 engine and IMA with VCM, the Accord Hybrid Sedan provides even more power – 255 hp versus 240hp in the regular Accord V-6 Sedan – while improving fuel efficiency to an estimated 7.9 L/100km city / 5.9 L/100km highway – better than virtually all 4-cylinder intermediate sedans and similar to that of the Honda Civic Sedan, already a benchmark for fuel efficiency in the compact car class. 2005 Accord Hybrid Sedan - 1 - OVERVIEW The Honda Accord Hybrid Sedan is designed to show that a hybrid powertrain can be an important component in the mainstream of the automotive landscape that provides exceptional fuel economy while still improving power, performance and comfort. With the introduction of the 2000 Insight – North America’s first hybrid-powered car and still the leader of annual fuel economy ratings – Honda has been at the forefront of hybrid technology. The company followed up the Insight with a hybrid version of Canada’s best-selling compact car, the Civic Hybrid, introduced in 2002 as the first truly mainstream hybrid and the first application of hybrid technology to an existing, high-volume vehicle. With the addition of the Accord Hybrid, Honda becomes the only car company in North America with three hybrid models available to consumers. While using a more powerful and efficient version of Honda’s IMA system, the Accord Hybrid Sedan also incorporates new, leading-edge technologies that engineers are also applying to Honda’s main line of cars and trucks. Among these advanced technologies is its Variable Cylinder Management (VCM) system that allows for deactivation of three of the engine’s six cylinders during cruising. The system also features an Active Control Engine Mount (ACM) an Active Noise Control (ANC) system to eliminate the potential effects of three-cylinder operation on cabin noise and engine vibration. This same technology is also being applied on the all-new 2005 Odyssey minivan equipped with the available i-VTEC engine. In addition, the Accord Hybrid utilizes a dual scroll hybrid air conditioning compressor that is both belt (engine) and electric motor driven, allowing for more efficient operation of the Accord Hybrid’s dual zone automatic climate control system, even when the engine is in idle stop mode. Combined, these technologies along with improvements in aerodynamics and weight saving features like an aluminum hood, allow the Accord Hybrid to achieve an estimated fuel economy rating of 7.9 L/100km in the city and 5.9 L/100km highway, up from 11.4 L/100km city / 7.3 L/100km highway for the Accord EX V-6 Sedan – a fuel economy gain of 31 percent and 21 percent, respectively. The Accord’s Integrated Motor Assist System (60%) accounts for over half the gains in city fuel efficiency, while Variable Cylinder Management (15%) and idle stop 2005 Accord Hybrid Sedan - 2 - OVERVIEW (25%) is responsible for the rest. During highway cruising, the VCM system (57%) provides the majority of the increase, while IMA (38%) and a lower drag coefficient and greater aerodynamics (5%) also contribute.

The use of Honda’s new Variable Cylinder Management (VCM) system that deactivates the three of V-6 engine’s cylinders to save fuel during cruising and deceleration allow Honda engineers to maximize fuel economy while the hybrid IMA system helps to increase peak power by 15 hp and 20 lb.-ft. of torque over the current Accord EX V-6. The Accord Hybrid Sedan improves on the current Accord V-6’s 0-100 km/h time by half a second (7.5 sec. vs. 8.0 for an Accord EX V-6). In addition, peak torque of 232 lb.-ft @ 5000 rpm is now spread out over a much flatter curve, which makes 90 percent available at engine speeds less than 4000 rpm.

The 2005 Accord Hybrid Sedan adds to this foundation design cues intended to help it achieve top-of-class fuel economy and to improve the car’s aerodynamics and reduce its drag coefficient to a low 0.29. These additions include a rear decklid spoiler and lightweight 16” aluminum alloy aerodynamic wheels. Additionally, lightweight aluminum was used in the Accord Hybrid’s hood, bumper frames and rear suspension knuckles, helping to reduce overall weight. Powertrain In balancing the seemingly contradictory goals of high fuel efficiency and high performance, Honda combined the 3rd generation IMA system with the all-new Variable Cylinder Management (VCM) system that alone generates substantial fuel savings when full engine power is not needed (as in highway cruising Accord Hybrid Powertrain and deceleration). Working together, the two systems provide exceptional fuel efficiency benefits when the engine is not at full capacity, but intermediate class-leading power when the car is at full throttle. Overall, the VCM system helps to maximize highway fuel economy while the IMA system helps to maximize city fuel economy. The engine used on the Honda Accord Hybrid Sedan is primarily the same as that of the Accord V-6, but with a few modifications to save weight and to allow for the use of Honda’s VCM system. Foremost among these changes is the implementation of Honda’s advanced i-VTEC system in place of the VTEC system of the Accord EX V-6. 2005 Accord Hybrid Sedan - 5 - OVERVIEW Without any help from the electric IMA system, this 3.0L engine provides 240 hp and 217 lb.-ft of torque, but utilizes some lighter weight materials than the original version used in the standard Accord EX V-6. First introduced to North America in the all-new 2005 Odyssey minivan, Honda’s innovative Variable Cylinder Management (VCM) system has now been engineered to Variable Cylinder Management and Integrated Motor Assist maximize fuel economy in the Accord’s 3.0L i-VTEC V-6 in concert with the IMA system.
