There's 281 pound-feet of torque, but it is isn't fully there at lower rpm, so you do have to put your foot down to find all the power, and that doesn't come without a price in fuel efficiency. The PRO-4X gets 15 City and 19 Highway miles per gallon, which is no more than the full-size Dodge Ram pickup with a 390-horsepower Hemi V8 engine.
The four-cylinder engine with manual transmission gets an EPA-rated 19/23 mpg. It's available in a nicely equipped SE King Cab, so this might be an option.
The five-speed automatic transmission shifts in and out of fifth gear frequently, even at fairly low speeds during casual driving, but always smoothly and often invisibly. A manual mode would be useful, but isn't available.
On the highway, we drove Frontiers with both the short and long wheelbase, as well as our week in the PRO-4X with the off-road Bilstein gas-charged shock absorbers and big BFG trail tires, and we didn't encounter any bumps or situations that made us say: This thing rides like a truck.
The handling is also good, tight, never flabby or wallowy. In fact, it feels better than the Nissan Xterra SUV, which uses the Frontier chassis but has a higher center of gravity. The turning circle isn't nearly as tight as that of the Xterra, however. The chassis is a boxed-in steel ladder frame, with double wishbone front suspension and solid rear axle with leaf springs.
The part-time four-wheel-drive system, which can be easily shifted on the fly, is there to be used. Don't even think of driving off the pavement without engaging it, because it makes a world of difference. Even when you don't need it to keep from getting stuck, it transforms the Frontier; on gravel roads the Frontier is totally squirrelly in 2WD, but in 4WD it's stable. Even the ride is improved using 4WD, because the tires remain more in contact with the ground.
On those gravel roads, riding as a passenger in a 4WD King Cab, we found things a bit rough. Later, driving the PRO-4X for a couple hours on fire trails in the Pacific Northwest, no problem. Lots of fun. The good seats were a relief. But that's when we most would have liked a manual mode in the five-speed automatic transmission.
We also got on a closed off-road course, with specific steep challenges. We used 4WD in its low range to get over some ridges and ruts, and found that it allowed higher speeds than some other systems; but also found that it wasn't really needed except in the most extreme situations, because 4WD in high range is good.
You have to get the optional Traction Package to make the PRO-4X capable off-road; it includes Vehicle Dynamic Control, Hill Descent Control, and Hill Start Assist. We tested the HDC that allows you to travel down a steep hill and rely on electronics to slow and keep the truck safe and steady at about 5 mph, with throttle control and ABS automatically applied, meaning all the driver has to do is steer. If you live in a place that has snowy and icy hills in winter, HDC could save your life or the life of another, for example a passenger on the sidewalk because it allows you to maintain steering control.
Hill Start Assist allows you to start moving forward on a steep uphill, without drifting back. It applies the brakes for two seconds after you lift your foot off the brake pedal. However with an automatic transmission, that's not really a problem, because you can use two feet on the two pedals. Next Page
