Honda completely redesigned the Accord, making it bigger and more powerful in the process. By EPA interior volume standards, the Accord is now in the full size category, and larger in most dimensions than its main competitors, the Camry and Altima. Accord EX/EX-L models equipped with the 2.4L inline-4 are tuned for slightly more power than the base LX/LX-P models. The 4-cylinder is available with a 5-speed manual or automatic, while the 3.5L V-6 is coupled to the automatic only. Honda added VCM® variable displacement technology to the V-6 for improved fuel economy. Both engines meet ULEV-2/PZEV standards, depending on configuration. All Accords are equipped with VSA® stability control. An optional 270-watt audio system with subwoofer is available on EX-L models. The optional navigation system also includes Bluetooth® hands-free technology.
