2013 Dodge Ram 1500 Review
2013 Dodge Ram 1500 is the release of the third quarter of 2012 will be in great demand by customers for the best in class fuel economy, this car also won Ward 10 Best Engines award in his debut year in 2011 and 2012 was fantastic. There is a very nice feature that there are 2013 Dodge Ram 1500 is a new start-stop feature that automatically shuts down the engine when the engine suddenly died, fuel conservation. If you want to turn the machine back, the driver simply restart the machine again.
As a best in class fuel economy V6 – Pentastar V6 engine, in terms of speed of 2013 Dodge Ram 1500 has 305 horsepower at 6400 rpm and 269 lb.-ft. of torque at 4175 rpm 2013 Dodge Ram 1500 run from 0-60 mph, can take three seconds faster than the previous V6 powertrain. Machine that includes variable valve timing (VVT) with dual independent cam phasing helps fuel efficiency and volumetric better torque band. Peak torque of the engine of nearly 90 percent from 1800 to 6400 rpm.
As a best in class fuel economy v8 – 5.7 liter Hemi V8, in terms of speed of 2013 Dodge Ram 1500 has 395 horsepower at 5,600 rpm and 407 lb. ft. of torque at 3950 rpm. Fuel increases with the HEMI features including a cylinder shut-off technology, which deactivates four cylinders when the engine light acceleration or cruising on the highway situation when full V-8 power is not needed. In addition, the technology found in the car VVT technology serves to improve fuel economy and reduce engine pumping work by closing the intake valve and increase the expansion of the combustion event.
TorqueFlite 8 Automatic Transmission
This new eight-speed automatic transmission 8HP45 transmission is a new standard for the Ram 1500 with a V-6. For the HEMI ® V-8 – equipped Ram 1500 models, higher torque capacity 8HP70 version will be available in the first quarter of 2013.
Owners will appreciate the innovative e-swivel quick shift to trucks equipped with the new 8-speed transmission that replaces TorqueFlite both columns and floor shifter. The exclusive e-rotary shift allows intuitive operation with the feel of a direct and confident, even with gloves. , Convenient dash-mounted, easy to understand and operate the system provides total control of advanced eight-speed transmission and Ram Truck innovative approach to electronic shifter, is used in Class 6-8 trucks. The new design allows quick transition from blind-shift “Reverse” to “Drive” while towing or navigating from mud, snow or busy parking lots and crowded workplace. E-shift of the rotary dial also produce a more functional space for storage and can be used in the console.
Fully electronic, 8HP45 and 8HP70 transmission both features on-the-fly map shift change. More than 40 maps of individual shifts to very specific conditions to optimize shift quality and shift points for fuel economy and drivability performance. Intelligent software take into account variables including engine torque gradient, kicking to the event, longitudinal and lateral acceleration, hill detection, detection of friction and a shift to determine the detection map shifts accordingly. Additional parameters are integrated into the vehicle control strategies including speed control, electronic stability control and interaction of temperature. The result is an automatic shift ideally aligned with the performance requirements of virtually all driving demand.
The efficiency of transmission and spread of the ratio of width to give the best fuel economy by operating the engine at lower rpm on both city and highway environments. Driving at lower rpm also helps to effectively reduce emissions by almost 11 percent. Internally, the transmission gear ratios are used identically in both the 8HP45 and 8HP70 transmission.
The addition of more gear ratios also help reduce the gap is usually associated with upshifting and downshifting. Gear changes are almost invisible because it measures evenly spaced teeth of each gear ratio. Internally, both sets of gear transmission having four and five shift elements (multi-disc clutch and brake). Only two shift elements open at all times. With a little shift element is open, drag losses due to rotating parts relative to each other is reduced, improving fuel efficiency.
High effort shift has been eliminated with the gear selection is controlled by a shift by wire system. Shift in position, selected by the driver via e-shift dial turn on the instrument panel, transmitted electronically without mechanical connection to the outside of the transmission shifter. Elimination of this connection every effort to eliminate the shift of the driver’s gear selection but maintain the feel intuitive operation with direct and confident. Calibration is also improved for smooth shift in the garage or when parking.
Torque capacity for the 8HP45 is 332 lb.-ft. (450Nm). The 8HP70 is rated for heavy duty 516 lb.-ft. of torque capacity (700nm).
