Following GM’s announcement of official fuel economy and capability ratings for its new 4.3L V6 (LV3) engine that powers the 2014 Silverado and 2014 Sierra, we’ve compiled the following comparison of how the new standard engine compares to those from the competition.
|METRIC||GM 4.3L V6 LV3||FORD 3.7L V6||RAM 3.6L V6|
|TRANSMISSION||6-SPEED AUTO||6-SPEED AUTO||8-SPEED AUTO|
|POWER HP / kW||285 / 212||302 / 225||305 / 227|
|TORQUE LB-FT / Nm||305 / 413||278 / 376||269 / 364|
|2WD FUEL ECONOMY CITY / HWY||18 / 24||17 / 23||17 / 25|
|4WD FUEL ECONOMY CITY / HWY||17 / 22||16 / 21||16 / 23|
|MAXIMUM PAYLOAD LBS / KG||2108 / 956||1900 / 861||1550 / 703|
|MAXIMUM TOWING LBS / KG||7200 / 3265||6700 / 3039||N/A*|
The LV3 makes more torque than Ford’s 3.7L V6 and RAM’s 3.6L V6, allowing the Silverado and Sierra to claim the highest-available towing rating of 7,200 pounds, along with the highest-available payload rating of 2,108 pounds.
The 4.3L V6 LV3 doesn’t disappoint when it comes to fuel economy either, achieving best-in-class city fuel economy (by 1 MPG) compared to both Ford and RAM in both 2WD and 4WD applications. On the highway, however, the new six-banger achieves 1 MPG more than Ford’s V6, but falls short by 1 MPG to RAM’s V6 (also in both 2WD and 4WD applications). An 8-speed transmission, which has been rumored to make an appearance in the 2015 Silverado and 2015 Sierra, should help GM raise the highway fuel economy numbers of its new trucks.
