Honda unveiled this Accord Coupe Concept at Detroit, which should be just a concept in name. It shows off the styling direction for the next gen Accord, as well as a host of new technologies for the ninth-generation 2013 model, set to go on-sale in America this fall.

The 2013 Accord will feature three all-new powertrains, including a 2.4-litre direct-injected four-pot and two-motor plug-in hybrid system from Honda’s next-generation Earth Dreams technologies. In addition, the V6 Accord will be the first Honda sedan to feature a new 6-speed automatic transmission. Both the Accord Sedan and Coupe are expected to achieve class-leading fuel economy ratings in the US.

Honda says that the next gen Coupe will retain today’s size, but the new US Sedan, which we normally get, will feature a more compact exterior footprint with shortened length and reduced weight for “more responsive handling and improved driving dynamics.” Despite the smaller body, both the Sedan and Coupe will retain the current model’s generous cabin space.

The new 2.4L DI engine will make more than 181 hp and 240 Nm of torque, which is more that today’s 2.4L, while delivering better economy. This engine will be paired to a 6-speed manual or a new CVT, which utilises an innovative cooperative control system for “excellent acceleration and responsive shifting.”

Higher up, the re-engineered 3.5L V6 engine will be paired to a new 6-speed automatic transmission or a 6-speed manual. There will be an increase in horsepower and torque over the current model, and automatic transmission variants will come with Honda Variable Cylinder Management technology. Once again, class leading economy is the target.

The 2013 Accord range will also feature the first application of a new two-motor plug-in hybrid system in the Sedan. The system moves continuously through three modes – all-electric, gasoline-electric and direct-drive.

In all-electric mode, the car will use a 6 kilowatt-hour lithium-ion battery and a 120 kW electric motor to achieve an all-electric range of approximately 16 to 24 km in city driving scenarios and a top speed of 100 km/h. A full charge will take less than four hours using a 120-volt, outlet and less than 1.5 hours using a 240-volt charger.

In the gasoline-electric mode, the Accord is powered by a 2.0L, i-VTEC inline four Atkinson cycle engine, paired with an electric Continuously Variable Transmission (E-CVT). For more efficient high-speed cruising, the Accord Plug-In Hybrid can engage in a direct-drive mode, in which only the engine drives the front wheels. This model will debut late next year.
