2014 Toyota Tundra Engine Comparison: What’s the difference in the 4L & the 5.7L engine?

The 2014 Toyota Tundra is one of the most popular trucks on the market. It is a full-size pickup truck with several different cab options; the base model with a regular cab will seat five, although other choices can bring the seating up to six.

In addition to the normal choices in terms of cab size, truck bed length, and trim, you will also get the chance to select the engine you want for your 2014 Tundra. There are three options: a 4-liter, a 4.6-liter, and a 5.7-liter, each of which is considered an upgrade.

Various Engine Options

The standard engine is the 4.L gas V6 engine. The next choice is a 4.6L V8 gas engine, and the final is a 5.7L gas V8 engine. The major differences between the 4L and 5.7L engines are based on overall size and being a V6 versus V8. These are considered the least and most powerful engines options, but each can be a good option.

Horsepower and Torque

The standard 4L V6 engine has 270 horsepower and a torque of 278 pound-feet. The 5.7L V8 engine is significantly more powerful with 381 horsepower and a torque of 401 foot-pounds. If you want a middle ground, you can opt for the 4.6L, which gets 310 horsepower and 327 foot-pounds of torque. The 4L is generally powerful enough for most everyday functions, but those who planning on using their Tundra for towing or simply need more power could do well with the 5.7L.

Associated Transmissions and Fuel Economy

Due to the variations in power, you will get different standard transmission and fuel economy depending on which size engine you opt for. The 4.L will come standard with a five-speed automatic transmission. This engine will usually get around 16 mpg in the city and 20 on the highway for a combined gas mileage of 17 mpg*, a fairly good number for a full-size pickup truck. The 5.7L has a six-speed automatic transmission standard. Because of the added power, trucks with this engine will get slightly worse gas mileage at 13 mpg in the city and 18 on the highway for a combined total of 15 mpg*.

Towing

The standard towing capacity associated with the 4L (when in a 2014 Toyota Tundra SR 4WD) is 4,800 pounds with a maximum payload of 1,630. Due to its added power, you can expect better numbers from the 5.7L, which has a towing capacity of about 10,400 pounds.

Trim Options

Although you have the option for an upgrade in most trim levels, not all engines are available with all trims. The 4L is standard with the rear-wheel drive SR models. The 5.7L is standard for 4WD models with regular cabs, as well as all Limited, Platinum, and 1794 trim options.
