Honda Accord EX
From Honda press: Three engines are available for the Accord: There is 3.0-liter, 200-horsepower, 24-valve V-6 and two 2.3-liter 4-cylinder engines. A 5-speed manual transmission is standard on 4-cylinder models and a 4-speed automatic transmission is available for the 4-cylinder engines and standard on V-6 models.
The 3.0-liter, 200-horsepower, 24-valve V-6 is the first V-6 engine to use VTEC (Honda Variable valve Timing and valve Lift Electronic Control system), Honda's variable valve timing system. VTEC helps give the V-6 a broader, more powerful torque curve. All engines and transmissions are built at Honda facilities in Ohio.
The Accord's 2.3-liter, in-line 4-cylinder engine is shared by DX, LX and EX models and features a 16-valve cylinder head and a vibration-canceling second-order balance system. Both LX and EX engines receive California Low-Emission Vehicle (LEV) certification, thanks in part to the application of VTEC technology.
Accord V-6 sedans and coupes are powered by an aluminum-alloy, transversely mounted, 3.0-liter, 200-hp V-6 engine. The engine features 4 valves per cylinder (24 total), single overhead camshafts and VTEC.
The V-6 is quite compact and incorporates several innovative features that help minimize its size, weight, friction and vibration. The block is heat-treated, die-cast aluminum and is very compact and rigid, with a high natural frequency and minimal resonant vibration. In addition, its 60-degree V angle serves to minimize vibration. Bore and stroke are "square," each measuring 86 mm, for a total displacement of 2997 cc. The cylinder liners are cast-iron.
The 2.3-liter, 4-cylinder Accord engine has been engineered to meet the goals of more power, greater noise and vibration reduction, and lower emissions. Horsepower and torque figures for the engine are 150 hp @ 5700 rpm and 152 lb.-ft. @ 4900 rpm for the LX and EX models (ULEV EX is 148 hp). The DX model's engine produces 135 hp @ 5400 rpm and 145 lb.-ft. torque @ 4700 rpm for the DX model.
Acceleration (0-60) for the 4-cylinder models is improved (around the mid-9-second mark), with comparable fuel efficiency to its predecessor: 23 mpg/city and 30 mpg/hwy for LX and EX models with automatic transmissions.
Emissions of Non-Methane Organic Gases (NMOG), also known as unburned hydrocarbons, produced during engine warm-up are considerably lower. The LX and EX engines produce less than 0.0075 grams per mile, qualifying them for California LEV (Low-Emission Vehicle) status. In California, the Accord EX with the available automatic transmission will produce less than 0.003 grams per mile of NMOG, qualifying it as the first gasoline-powered vehicle to reach ULEV (Ultra-Low Emission Vehicle) status.
