The Accord sedan has been completely redesigned for 2008. It is available in six trims: LX, LX-P, EX, EX V6, EX-L, and EX-L V6. Engine choices include a 2.4L four-cylinder engine or a new 268-horsepower 3.5L i-VTEC V6 engine with Variable Cylinder Management (VCM). The VCM system can operate on six, four or three-cylinders to improve fuel efficiency, resulting in an EPA fuel economy rating of 19 city and 29 highway miles per gallon (Accord Sedan V-6). The 2.4L four-cylinder engine is mated to either a five-speed manual or automatic transmission while the 3.5L V6 is available with a five-speed automatic or six-speed manual transmission. Also new on the Accord is an Advanced Compatibility Engineering (ACE) body structure that enhances frontal collision compatibility with vehicles of different sizes and bumper heights.
