The new duel VV-I engine technology adds to the already existent fuel efficiency of the Toyota Yaris. The Variable Valve Timing ensures that both the intake and the exhaust valves are regulated, creating a more efficient system. It averages 55 miles per gallon. The intelligence factor senses the driving conditions of the vehicle and slows down or speeds up depending. This works well for traveling on hills or other inconsistent terrain. With direct ignition, there is no need for spark plugs wires. This takes away some of the maintenance of the engine and is an important component to many of the desirable features of the Yaris. Finally, the Start/Stop System is important to the emissions and lack of fuel consumption. At an idle, when the vehicle is in neutral, it automatically turns the vehicle off. As the clutch is pressed down again, the vehicle restarts. All of these factors add not only to the fuel efficiency, but also the over all performance of the Yaris.
With better gas mileage, better sensitivity and a reduction in admissions, the Yaris is a perfect example of the ever-improving engine technology from Toyota. On the down side, with only 106 horsepower, many consider the engine too small and suggest that it does not have enough power behind it. This is especially true when compared to other vehicles of similar size and emerges in certain driving conditions. For example, when a quick acceleration in needed to avoid a collision, the Yaris does not have enough power to move the vehicle quickly. Also, the noise created by the engine itself can become aggravating as the drive continues. It has been described as a “buzzing†noise that can distract from the enjoyment of the ride.
