Renewed Ram comparisons

With both Chevrolet Colorado and Ford F-150 boasting of their fuel economy— the latter without actually releasing it yet — Ram has done the footwork to provide comparisons of their mileage versus every competitor.

Of note, the Ram 1500 V6 is no longer the most efficient full-sized gasoline-powered pickup, though it is tied for best with the Chevrolet Silverado. The Ram 1500 diesel does retain the title of most efficient full or midsized pickup, arguably, with Tacoma coming in at the same rounded combined mileage (1 mpg better city, 3 mpg worse highway). Tacoma is smaller, and comes with a four cylinder engine coupled to a manual transmission.

The new Ford F-150’s gas mileage has yet to be revealed; the company has already said that it will be the highest-mileage F-150 ever,  but has not said it will be the best in the full size segment.

Ram wrote that their 1500 achieved strong mileage through its low drag (0.36 cD compared with mode of around 0.40, resulting in a gain of around 0.4 mpg on the highway); eight-speed automatic and parasitic loss prevention systems (around 2 mpg gain); and diesel engine (around 6 mpg gain). A Ram press release claimed that a 500 pound weight reduction results in around a 2% increase in fuel economy, or around 0.5 mpg.

Ford continues to enjoy a reputation for fuel economy, though F-150 is near the bottom of the class, ironically only beating a pair of Japanese trucks. The top two trucks in fuel economy come from two companies whose reputation among the general public is, also ironically, for inefficient powertrains: Chrysler/Ram and GM/Chevrolet.

Top 9 Most Fuel-Efficient Trucks for 2014

2014 truck of the year2 copy

For the past several years, the best-selling vehicle in the nation has been a pickup. It’s not difficult to understand why Americans love trucks. Pickups offer the kind of unassailable utility that makes them a natural fit for anyone who frequently hauls outsize cargo.

Certain trucks offer another benefit: outstanding fuel efficiency. The nine models shown offer the best gas mileage in the segment. Our list is shorter than the usual 10 due to a shrinking talent pool. GM’s hybrid trucks made appearances on last year’s list, but for 2014, GM has dropped these hybrids from its lineup.

Our list this year includes fuel-efficient gas-only models like the Nissan Frontier, Ram 1500 and Toyota Tacoma. Note that each model is allowed just one appearance on our list, for its most fuel-efficient powertrain.

Each vehicle’s ranking is determined by its Environmental Protection Agency (EPA) combined fuel economy rating. The EPA’s combined fuel economy rating is based on miles-per-gallon ratings for city and highway travel, using the following formula: 55 percent of city mpg rating plus 45 percent of highway mpg rating.

1. Toyota Tacoma — 23 mpg combined (21 city/25 highway) (tie)

1. Ram 1500 — 23 mpg combined (20 city/28 highway) (tie)

2. Nissan Frontier — 21 mpg combined (19 city/23 highway)

3. Chevrolet Silverado 1500 — 20 mpg combined (18 city/24 highway) (tie)

3. GMC Sierra 1500 — 20 mpg combined (18 city/24 highway) (tie)

4. Ford F-150 — 19 mpg combined (17 city/23 highway)

5. Honda Ridgeline — 17 mpg combined (15 city/21 highway) (tie)

5. Toyota Tundra — 17 mpg combined (16 city/20 highway) (tie)

6. Nissan Titan — 15 mpg combined (13 city/18 highway)

Ram diesel: official mileage

The 2014 Ram 1500 pickup, powered by the VM 3-liter V6 (also used in Jeep Grand Cherokee), set a best-ever full-size-pickup 28 mpg in EPA highway testing, neatly beating all current mid-size and full-size pickups. Before the diesel, the best full-size pickup highway mileage was set by Ram 1500 V6.

The half-ton pickup also set a new combined city/highway benchmark of 23 mpg, matching the best four-cylinder midsize pickup’s record. The Ram 1500 diesel  is rated at 20 city, 28 highway, and 23 combined, where the Toyota Tacoma, with a four-cylinder engine and manual transmission, is rated at 21 city, 25 highway, 23 combined. Ram 1500 easily beat the Nissan Frontier and Honda Ridgeline midsize pickups, as well as all Ford, Toyota, GM, and Nissan full-size trucks.

Ram chief Reid Bigland said, “To put the Ram 1500 EcoDiesel in context, it gets 6 mpg better fuel economy than the best F150 EcoBoost. Overall, the Ram 1500 EcoDiesel has outstanding pick-up truck capability with compact car-like fuel economy.”

Ordering will begin on February 7, in all 50 states (and presumably in Canada).

The engine delivers peak torque unsurpassed among V-6 pickups (420 lb-ft). Ram 1500 remains the only pickup with eight-speed automatics, and the only half-ton pickup with an optional diesel.

Torque is higher than the base F-150 V8 and Silverado 1500 V8s , both rated at 15 city, 21 highway; and the Ram Hemi, rated at 14/20 with six-speed, and 15/22 with eight-speed.  (The base Nissan Titan V8 is rated 13/18, while the base Tundra V8 is 15/19).  The Ram 1500 diesel is rated to tow 9,200 lb.

The engine’s block and bedplate are made from lightweight Compacted Graphite Iron (CGI); it uses Fiat’s highly praised MultiJet 2 common-rail fuel-injection system, whose high-dispersion nozzles and servovalve can accommodate up to eight fuel-injection events per cylinder cycle. This mitigates noise and improves low-speed throttle response, while cutting fuel consumption and emissions. Other features include Selective Catalytic Reduction (SCR), high-pressure cooled Exhaust Gas Recirculation (EGR), variable swirl intake ports, and a variable-geometry turbocharger (pioneered by Chrysler with the 2.2 Turbo IV).

One of Ward’s 10 Best Engines for 2014, the EcoDiesel V-6 was a major factor in the Ram 1500’s selection as 2014 Motor Trend Truck of the Year.  Powertrain chief Bob Lee said, “We are immensely gratified by achieving these milestones. Not only do they confirm our position as an industry leader in powertrain development and truck design, they promise tremendous benefits for our customers.”

The truck also has a thermal-management system that quickly warms transmission oil to reduce pumping losses associated with cold, low-viscosity fluid, active grille shutters, electric power steering, and aluminum for components, such as hoods, “that do not compromise capability.”

The diesel engine adds $2,850 to the cost of the 2014 Ram 1500, which starts at $24,200; the diesel includes the eight-speed automatic, but even without that, the “diesel premium” is far lower than with the hefty Cummins diesel available on Ram 2500-5500. The truck has a five-year /100,000-mile powertrain warranty and three-year / 36,000-mile bumper-to-bumper warranty.  It is built in Warren, Michigan (which has assembled more than 12.5 million trucks since it started operations in 1938) except for regular cabs, which are made in Saltillo, Mexico. VM engines are made in Cento, Italy, while the eight-speed automatics are made in the United States.
