The redesigned for the 2013 model year Ram 1500 pickup truck now claims to be the most fuel-efficient model in the full-size segment when fitted with the base 3.6-liter Pentastar V6 engine coupled to a new (and standard) 8-speed automatic transmission.

With this setup, the lighter and more aerodynamic 2013 Ram 1500 is said to return 18mpg (13.1 lt/100km) in the city and 25mpg (9.4lt/100km) in highway driving.

According to the automaker, the new 3.6-liter Pentastar V6 engine features 42 percent more horsepower at 305HP, 13 percent more torque at 269 lb.-ft. and at least 20 percent better fuel economy when compared to the previous 3.7-liter V6 engine paired to a four-speed auto.

The 2013 Ram 1500 with the Pentastar V6 not only beats the most fuel efficient versions of its main rivals, the Ford F-150 with a 302hp 3.7-liter V6 (17mpg city / 23mpg hwy) and the Chevy Silverado with the 195hp 4.3-liter V6 (15mpg City / 20 mpg hwy), but it also matches the fuel economy of the smaller Chevy Colorado mid-size pickup truck with a 185hp 2.9L inline-four (18mpg city / 25mpg hwy).

The new 1500 is slated to go on sale in the States later in the fall with prices to be announced.
