The 4.0L V6 Engine fills the bill for the 2010 Nissan Frontier

The 2010 Nissan Frontier offers two engine options to tackle the demands for nearly any task or trip. A 2.7L I4 delivers plenty of power for in-town driving and other light duties, while the 4.0L V6 provides ample muscle for towing and venturing off road. And, only 87 octane gas is sufficient for either engine.

The XE trim and some SE models come standard with a 2.5L I4. With each cylinder featuring a 89.0 mm bore, a 100.0 mm stroke, and a 9.5:1 compression ratio, nobody should underestimate this engine. Double overhead cams, variable valve timing, and multi-port fuel injection keep the fuel economy up to 21 mpg while exerting enough muscle for light duties. Up to 152 horsepower can be called upon at 5200 rpm, while a peak torque of 171 lb-ft is delivered at 4400 rpm.

For those applications requiring a little more oomph, the 4.0L V6 fills the bill. Each cylinder features a 95.0 mm bore, a 92.0 mm stroke, and 9.7:1 compression ratio. Just like the smaller I4 counterpart, it too comes with double overhead cams. The variable valve timing and multi-port injection system provide for a peppy engine that is still respectable in fuel economy, even with 4WD. A Frontier with the 4.0L V6 can be expected to average around 16 or 17 mpg. And, it still outputs 261 horsepower at 5600 rpm, and delivering 281 lb-ft of torque at 4000 rpm, which makes this engine the most powerful V6 for any engine in the compact pickup truck market.

Nissan has employed nearly every trick it can beyond sophisticated engine control modules to increase horsepower and torque while maintaining a reasonable fuel economy. Both engine options feature direct coil ignition. And, they meet the stringent EPA Tier 2 Emissions requirements while meeting the driver's demands.
