2013 Honda Accord prototype - camouflaged front 3/4 view

Honda is set to unveil its new "Earth Dreams" family of engines, and while the lineup will make its debut in the all-new Accord, the more efficient powertrains are poised to spread throughout the lineup.

According to an Automotive News report, the direct-injected, dual overhead cam powerplant range is said to be good for a 10-percent increase in fuel economy over the current lineup.

Also mentioned in the story is the possibility of getting a 1.6-liter diesel with 220 pound feet of torque here in the States, and possibly a large-car hybrid setup. Will Honda renew the short-lived Accord Hybrid?

The report is not limited to engine technology, as Automotive News says Honda will move to Continuously Variable Transmissions in a much larger way. We've known for some time that the Japanese automaker is poised to go the belt and pulley route, but it hasn't been clear what vehicles will receive the transmission. Not every vehicle will get a CVT, as the report states that "performance models and off-road vehicles will retain geared transmissions."

AN also provided a breakdown of future product plans, which include a redesigned Fit in summer of 2014, with a 1.5-liter four-cylinder paired with a CVT. Europe will get a hybrid Fit, but American plans for the hybrid version have reportedly been nixed. Honda's smallest offering, may also spawn a compact crossover, slotted below the CR-V, but it's not expected until Spring, 2015.

In other portfolio news, the aging Pilot three-row crossover will receive a new 3.5-liter Earth Dreams V6 when the model is redesigned for 2014. Power is expected to be on the order of 310 horsepower and 265 pound-feet of torque, and a CVT is also part of the program, but only on front-drive models. Also included is additional confirmation that the Civic will get an emergency refresh, a mere 18 months after its launch triggered a lackluster response from critics.

Finally, the AN report also dangles the possibility of reviving the S2000 to compete with the Scion FR-S and Subaru BRZ, but then dashes hopes by saying that its not a priority for the Japanese automaker.
