We got into the Nissan Frontier after stepping out of a full-size Titan, and we must say that the Frontier made the Titan feel huge. And for the week we were in the Frontier, it never felt too small. So we might suggest that among the first things you should consider in choosing a Frontier (or any truck) are the size of the bed you need, and the seating capacity. (That's assuming you don't need the full-size Titan for towing.) Remember that tailgate extenders are available, if you occasionally need a longer bed for larger cargo.

On the road, the all-aluminum dohc V6 engine has very strong acceleration when you put your foot down; as it should, with its 261 horsepower. At 4.0 liters, it's a larger version of the award-winning 3.5-liter engine that's used in other Nissans. It has all the right stuff: Aluminum block and heads, Teflon-coated pistons, Continuous Valve Timing Control (CVTCS), Nissan variable Induction Control System (NICS), silent timing chain and micro finished camshaft and crankshaft surfaces, digital knock control system, and 105,000-mile spark plugs.

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. With four-wheel drive and an automatic transmission it's EPA-rated at 14 mpg City and 19 mpg Highway, so if maximum fuel efficiency is your goal you probably ought not to be looking at a truck in the first place.

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 a choice for a buyer who needs a tidy truck but not a whole lot of power.

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. 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 in 2WD may not be at its best, but in 4WD it's stable.

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.

We tested the Hill Descent Control 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 be of real benefit.

Hill Start Assist allows you to start moving forward on a steep uphill, without coasting backwards. It keeps the brakes applied for two seconds after you lift your foot off the brake pedal. However, with an automatic transmission, starting on hills is not really a problem, because you can use two feet on the two pedals.
